HP OpenView GlancePlus for HP-UX Dictionary of Operating System Performance Metrics Print Date 12/2006 OVPA for HP-UX Release C.04.60.000 Copyright 2006 Hewlett-Packard Development Company, L.P. All rights reserved. ************************************************************* Introduction ============ This dictionary contains definitions of the HP-UX operating system performance metrics for HP OpenView GlancePlus. This document is divided into the following sections: * "Metric Names by Data Class," which lists the metrics alphabetically by data class. * "Metric Definitions," which describes each metric in alphabetical order. * "Glossary," which provides a glossary of performance metric terms. NOTE: The name MeasureWare Agent for UNIX has been replaced with HP OpenView Performance Agent (OV Performance Agent or OVPA) for UNIX and the name PerfView for UNIX has been replaced with OV Performance Manager for UNIX throughout this documentation. However, the process names and software components operationally remain MeasureWare Agent (MWA) and PerfView.

APP_ACTIVE_APP ---------------------------------- The number of applications that had processes active (consuming cpu resources) during the interval. APP_ACTIVE_APP_PRM ---------------------------------- The number of PRM groups with at least one process that had activity during the interval. APP_ACTIVE_PROC ---------------------------------- An active process is one that exists and consumes some CPU time. APP_ACTIVE_PROC is the sum of the alive-process- time/interval-time ratios of every process belonging to an application that is active (uses any CPU time) during an interval. The following diagram of a four second interval showing two processes, A and B, for an application should be used to understand the above definition. Note the difference between active processes, which consume CPU time, and alive processes which merely exist on the system. ----------- Seconds ----------- 1 2 3 4 Proc ---- ---- ---- ---- ---- A live live live live B live/CPU live/CPU live dead Process A is alive for the entire four second interval, but consumes no CPU. A's contribution to APP_ALIVE_PROC is 4*1/4. A contributes 0*1/4 to APP_ACTIVE_PROC. B's contribution to APP_ALIVE_PROC is 3*1/4. B contributes 2*1/4 to APP_ACTIVE_PROC. Thus, for this interval, APP_ACTIVE_PROC equals 0.5 and APP_ALIVE_PROC equals 1.75. Because a process may be alive but not active, APP_ACTIVE_PROC will always be less than or equal to APP_ALIVE_PROC. This metric indicates the number of processes in an application group that are competing for the CPU. This metric is useful, along with other metrics, for comparing loads placed on the system by different groups of processes. On non HP-UX systems, this metric is derived from sampled process data. Since the data for a process is not available after the process has died on this operating system, a process whose life is shorter than the sampling interval may not be seen when the samples are taken. Thus this metric may be slightly less than the actual value. Increasing the sampling frequency captures a more accurate count, but the overhead of collection may also rise. APP_ALIVE_PROC ---------------------------------- An alive process is one that exists on the system. APP_ALIVE_PROC is the sum of the alive-process-time/interval- time ratios for every process belonging to a given application. The following diagram of a four second interval showing two processes, A and B, for an application should be used to understand the above definition. Note the difference between active processes, which consume CPU time, and alive processes which merely exist on the system. ----------- Seconds ----------- 1 2 3 4 Proc ---- ---- ---- ---- ---- A live live live live B live/CPU live/CPU live dead Process A is alive for the entire four second interval but consumes no CPU. A's contribution to APP_ALIVE_PROC is 4*1/4. A contributes 0*1/4 to APP_ACTIVE_PROC. B's contribution to APP_ALIVE_PROC is 3*1/4. B contributes 2*1/4 to APP_ACTIVE_PROC. Thus, for this interval, APP_ACTIVE_PROC equals 0.5 and APP_ALIVE_PROC equals 1.75. Because a process may be alive but not active, APP_ACTIVE_PROC will always be less than or equal to APP_ALIVE_PROC. On non HP-UX systems, this metric is derived from sampled process data. Since the data for a process is not available after the process has died on this operating system, a process whose life is shorter than the sampling interval may not be seen when the samples are taken. Thus this metric may be slightly less than the actual value. Increasing the sampling frequency captures a more accurate count, but the overhead of collection may also rise. APP_COMPLETED_PROC ---------------------------------- The number of processes in this group that completed during the interval. On non HP-UX systems, this metric is derived from sampled process data. Since the data for a process is not available after the process has died on this operating system, a process whose life is shorter than the sampling interval may not be seen when the samples are taken. Thus this metric may be slightly less than the actual value. Increasing the sampling frequency captures a more accurate count, but the overhead of collection may also rise. APP_CPU_NICE_TIME ---------------------------------- The time, in seconds, that processes in this group were using the CPU in user mode at a nice priority during the interval. On HP-UX, the NICE metrics include positive nice value CPU time only. Negative nice value CPU is broken out into NNICE (negative nice) metrics. Positive nice values range from 20 to 39. Negative nice values range from 0 to 19. On a system with multiple CPUs, this metric is normalized. That is, the CPU used over all processors is divided by the number of processors online. This represents the usage of the total processing capacity available. APP_CPU_NICE_UTIL ---------------------------------- The percentage of time that processes in this group were using the CPU in user mode at a nice priority during the interval. On HP-UX, the NICE metrics include positive nice value CPU time only. Negative nice value CPU is broken out into NNICE (negative nice) metrics. Positive nice values range from 20 to 39. Negative nice values range from 0 to 19. On a system with multiple CPUs, this metric is normalized. That is, the CPU used over all processors is divided by the number of processors online. This represents the usage of the total processing capacity available. APP_CPU_NNICE_TIME ---------------------------------- The time, in seconds, that processes in this group were using the CPU in user mode at a nice priority calculated from using negative nice values during the interval. On HP-UX, the NICE metrics include positive nice value CPU time only. Negative nice value CPU is broken out into NNICE (negative nice) metrics. Positive nice values range from 20 to 39. Negative nice values range from 0 to 19. On a system with multiple CPUs, this metric is normalized. That is, the CPU used over all processors is divided by the number of processors online. This represents the usage of the total processing capacity available. APP_CPU_NNICE_UTIL ---------------------------------- The percentage of time that processes in this group were using the CPU in user mode at a nice priority calculated from using negative nice values during the interval. On HP-UX, the NICE metrics include positive nice value CPU time only. Negative nice value CPU is broken out into NNICE (negative nice) metrics. Positive nice values range from 20 to 39. Negative nice values range from 0 to 19. On a system with multiple CPUs, this metric is normalized. That is, the CPU used over all processors is divided by the number of processors online. This represents the usage of the total processing capacity available. APP_CPU_NORMAL_TIME ---------------------------------- The time, in seconds, that processes in this group were in user mode at a normal priority during the interval. Normal priority user mode CPU excludes CPU used at real-time and nice priorities. APP_CPU_NORMAL_UTIL ---------------------------------- The percentage of time that processes in this group were in user mode running at normal priority during the interval. Normal priority user mode CPU excludes CPU used at real-time and nice priorities. On a system with multiple CPUs, this metric is normalized. That is, the CPU used over all processors is divided by the number of processors online. This represents the usage of the total processing capacity available. APP_CPU_REALTIME_TIME ---------------------------------- The time, in seconds, that the processes in this group were in user mode at a "realtime" priority during the interval. "Realtime" priority is 0-127. APP_CPU_REALTIME_UTIL ---------------------------------- The percentage of time that processes in this group were in user mode at a "realtime" priority during the interval. "Realtime" priority is 0-127. On a system with multiple CPUs, this metric is normalized. That is, the CPU used over all processors is divided by the number of processors online. This represents the usage of the total processing capacity available. APP_CPU_SYS_MODE_TIME ---------------------------------- The time, in seconds, during the interval that the CPU was in system mode for processes in this group. A process operates in either system mode (also called kernel mode on Unix or privileged mode on Windows) or user mode. When a process requests services from the operating system with a system call, it switches into the machine's privileged protection mode and runs in system mode. On a system with multiple CPUs, this metric is normalized. That is, the CPU used over all processors is divided by the number of processors online. This represents the usage of the total processing capacity available. APP_CPU_SYS_MODE_UTIL ---------------------------------- The percentage of time during the interval that the CPU was used in system mode for processes in this group. A process operates in either system mode (also called kernel mode on Unix or privileged mode on Windows) or user mode. When a process requests services from the operating system with a system call, it switches into the machine's privileged protection mode and runs in system mode. On a system with multiple CPUs, this metric is normalized. That is, the CPU used over all processors is divided by the number of processors online. This represents the usage of the total processing capacity available. High system CPU utilizations are normal for IO intensive groups. Abnormally high system CPU utilization can indicate that a hardware problem is causing a high interrupt rate. It can also indicate programs that are not making efficient system calls. APP_CPU_TOTAL_TIME ---------------------------------- The total CPU time, in seconds, devoted to processes in this group during the interval. On a system with multiple CPUs, this metric is normalized. That is, the CPU used over all processors is divided by the number of processors online. This represents the usage of the total processing capacity available. APP_CPU_TOTAL_UTIL ---------------------------------- The percentage of the total CPU time devoted to processes in this group during the interval. This indicates the relative CPU load placed on the system by processes in this group. On a system with multiple CPUs, this metric is normalized. That is, the CPU used over all processors is divided by the number of processors online. This represents the usage of the total processing capacity available. Large values for this metric may indicate that this group is causing a CPU bottleneck. This would be normal in a computation-bound workload, but might mean that processes are using excessive CPU time and perhaps looping. If the "other" application shows significant amounts of CPU, you may want to consider tuning your parm file so that process activity is accounted for in known applications. APP_CPU_TOTAL_UTIL = APP_CPU_SYS_MODE_UTIL + APP_CPU_USER_MODE_UTIL NOTE: On Windows, the sum of the APP_CPU_TOTAL_UTIL metrics may not equal GBL_CPU_TOTAL_UTIL. Microsoft states that "this is expected behavior" because the GBL_CPU_TOTAL_UTIL metric is taken from the NT performance library Processor objects while the APP_CPU_TOTAL_UTIL metrics are taken from the Process objects. Microsoft states that there can be CPU time accounted for in the Processor system objects that may not be seen in the Process objects. APP_CPU_TOTAL_UTIL_CUM ---------------------------------- The average CPU time per interval for processes in this group over the cumulative collection time, or since the last PRM configuration change on HP-UX. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. APP_CPU_USER_MODE_TIME ---------------------------------- The time, in seconds, that processes in this group were in user mode during the interval. User CPU is the time spent in user mode at a normal priority, at real-time priority (on HP-UX, AIX, and Windows systems), and at a nice priority. On a system with multiple CPUs, this metric is normalized. That is, the CPU used over all processors is divided by the number of processors online. This represents the usage of the total processing capacity available. APP_CPU_USER_MODE_UTIL ---------------------------------- The percentage of time that processes in this group were using the CPU in user mode during the interval. User CPU is the time spent in user mode at a normal priority, at real-time priority (on HP-UX, AIX, and Windows systems), and at a nice priority. High user mode CPU percentages are normal for computation- intensive groups. Low values of user CPU utilization compared to relatively high values for APP_CPU_SYS_MODE_UTIL can indicate a hardware problem or improperly tuned programs in this group. On a system with multiple CPUs, this metric is normalized. That is, the CPU used over all processors is divided by the number of processors online. This represents the usage of the total processing capacity available. APP_DISK_FS_IO_RATE ---------------------------------- The number of file system disk IOs for processes in this group during the interval. Only local disks are counted in this measurement. NFS devices are excluded. These are physical IOs generated by user file system access and do not include virtual memory IOs, system IOs (inode updates), or IOs relating to raw disk access. An exception is user files accessed via the mmap(2) call, which will not show their physical IOs in this category. They appear under virtual memory IOs. APP_DISK_LOGL_IO_RATE ---------------------------------- The number of logical IOs per second for processes in this group during the interval. Only local disks are counted in this measurement. NFS devices are excluded. On many Unix systems, logical disk IOs are measured by counting the read and write system calls that are directed to disk devices. Also counted are read and write system calls made indirectly through other system calls, including readv, recvfrom, recv, recvmsg, ipcrecvcn, recfrom, writev, send, sento, sendmsg, and ipcsend. On many Unix systems, there are several reasons why logical IOs may not correspond with physical IOs. Logical IOs may not always result in a physical disk access, since the data may already reside in memory -- either in the buffer cache, or in virtual memory if the IO is to a memory mapped file. Several logical IOs may all map to the same physical page or block. In these two cases, logical IOs are greater than physical IOs. The reverse can also happen. A single logical write can cause a physical read to fetch the block to be updated from disk, and then cause a physical write to put it back on disk. A single logical IO can require more than one physical page or block, and these can be found on different disks. Mirrored disks further distort the relationship between logical and physical IO, since physical writes are doubled. APP_DISK_LOGL_READ ---------------------------------- The number of logical reads for processes in this group during the interval. Only local disks are counted in this measurement. NFS devices are excluded. On many Unix systems, logical disk IOs are measured by counting the read system calls that are directed to disk devices. Also counted are read system calls made indirectly through other system calls, including readv, recvfrom, recv, recvmsg, ipcrecvcn, recfrom, send, sento, sendmsg, and ipcsend.

APP_DISK_LOGL_READ_RATE ---------------------------------- The number of logical reads per second for processes in this group during the interval. Only local disks are counted in this measurement.

APP_DISK_LOGL_WRITE ---------------------------------- The number of logical writes for processes in this group during the interval. Only local disks are counted in this measurement. NFS devices are excluded. On many Unix systems, logical disk IOs are measured by counting the write system calls that are directed to disk devices. Also counted are write system calls made indirectly through other system calls, including writev, recvfrom, recv, recvmsg, ipcrecvcn, recfrom, send, sento, sendmsg, and ipcsend.

APP_DISK_LOGL_WRITE_RATE ---------------------------------- The number of logical writes per second for processes in this group during the interval. Only local disks are counted in this measurement. NFS devices are excluded. On many Unix systems, logical disk IOs are measured by counting the write system calls that are directed to disk devices. Also counted are write system calls made indirectly through other system calls, including writev, recvfrom, recv, recvmsg, ipcrecvcn, recfrom, send, sento, sendmsg, and ipcsend.

Mirrored disks further distort the relationship between logical and physical IO, since physical writes are doubled. APP_DISK_PHYS_IO_RATE ---------------------------------- The number of physical IOs per second for processes in this group during the interval. APP_DISK_PHYS_READ ---------------------------------- The number of physical reads for processes in this group during the interval. APP_DISK_PHYS_READ_RATE ---------------------------------- The number of physical reads per second for processes in this group during the interval. APP_DISK_PHYS_WRITE ---------------------------------- The number of physical writes for processes in this group during the interval. APP_DISK_PHYS_WRITE_RATE ---------------------------------- The number of physical writes per second for processes in this group during the interval. APP_DISK_RAW_IO_RATE ---------------------------------- The total number of raw IOs for processes in this group during the interval. Only accesses to local disk devices are counted. APP_DISK_SUBSYSTEM_QUEUE ---------------------------------- The average number of processes or kernel threads in this group that were blocked on the disk subsystem (waiting for their file system IOs to complete) during the interval. This is the sum of processes or kernel threads in the DISK, INODE, CACHE and CDFS wait states. It does not include processes or kernel threads doing raw IO to disk devices. The Application QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues, within the context of a specific application. The Application WAIT PCT metrics, which are also based on block states, represent the percentage of processes or kernel threads that were alive on the system within the context of a specific application. These values will vary greatly depending on the application. No direct comparison is reasonable with the Global Queue metrics since they represent the average number of all processes or kernel threads that were alive on the system. As such, the Application WAIT PCT metrics cannot be summed or compared with global values easily. In addition, the sum of each Application WAIT PCT for all applications will not equal 100% since these values will vary greatly depending on the number of processes or kernel threads in each application. For example, the GBL_DISK_SUBSYSTEM_QUEUE values can be low, while the APP_DISK_SUBSYSTEM_WAIT_PCT values can be high. In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. APP_DISK_SUBSYSTEM_WAIT_PCT ---------------------------------- The percentage of time processes or kernel threads in this group were blocked on the disk subsystem (waiting for their file system IOs to complete) during the interval. This is the sum of processes or kernel threads in the DISK, INODE, CACHE and CDFS wait states. It does not include processes or kernel threads doing raw IO to disk devices. A percentage of time spent in a wait state is calculated as the accumulated time kernel threads belonging to processes in this group spent waiting in this state, divided by accumulated alive time of kernel threads belonging to processes in this group during the interval. For example, assume an application has 20 kernel threads. During the interval, ten kernel threads slept the entire time, while ten kernel threads waited on terminal input. As a result, the application wait percent values would be 50% for SLEEP and 50% for TERM (that is, terminal IO). The Application QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues, within the context of a specific application. The Application WAIT PCT metrics, which are also based on block states, represent the percentage of processes or kernel threads that were alive on the system within the context of a specific application. These values will vary greatly depending on the application. No direct comparison is reasonable with the Global Queue metrics since they represent the average number of all processes or kernel threads that were alive on the system. As such, the Application WAIT PCT metrics cannot be summed or compared with global values easily. In addition, the sum of each Application WAIT PCT for all applications will not equal 100% since these values will vary greatly depending on the number of processes or kernel threads in each application. For example, the GBL_DISK_SUBSYSTEM_QUEUE values can be low, while the APP_DISK_SUBSYSTEM_WAIT_PCT values can be high. In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. APP_DISK_SYSTEM_IO_RATE ---------------------------------- The number of physical IOs per second generated by the kernel for file system management (inode accesses or updates) for processes in this group during the interval. APP_DISK_VM_IO_RATE ---------------------------------- The number of virtual memory IOs per second made on behalf of processes in this group during the interval. IOs to user file data are not included in this metric unless they were done via the mmap(2) system call. APP_INTERVAL ---------------------------------- The amount of time in the interval. APP_INTERVAL_CUM ---------------------------------- The amount of time over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. APP_IO_BYTE ---------------------------------- The number of characters (in KB) transferred for processes in this group to all devices during the interval. This includes IO to disk, terminal, tape and printers. APP_IO_BYTE_RATE ---------------------------------- The number of characters (in KB) per second transferred for processes in this group to all devices during the interval. This includes IO to disk, terminal, tape and printers. APP_IPC_SUBSYSTEM_QUEUE ---------------------------------- The average number of processes or kernel threads in this group blocked on the InterProcess Communication (IPC) subsystems (waiting for their interprocess communication activity to complete) during the interval. This is the sum of processes or kernel threads in the IPC, MSG, SEM, PIPE, SOCKT (that is, sockets) and STRMS (that is, streams IO) wait states. This is calculated as the accumulated time that all processes or kernel threads spent blocked on (IPC + MSG + SEM + PIPE + SOCKT + STRMS) divided by the interval time. The Application QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues, within the context of a specific application. The Application WAIT PCT metrics, which are also based on block states, represent the percentage of processes or kernel threads that were alive on the system within the context of a specific application. These values will vary greatly depending on the application. No direct comparison is reasonable with the Global Queue metrics since they represent the average number of all processes or kernel threads that were alive on the system.

This is the sum of processes or kernel threads in the IPC, MSG, SEM, PIPE, SOCKT (that is, sockets) and STRMS (that is, streams IO) wait states. A percentage of time spent in a wait state is calculated as the accumulated time kernel threads belonging to processes in this group spent waiting in this state, divided by accumulated alive time of kernel threads belonging to processes in this group during the interval. For example, assume an application has 20 kernel threads. During the interval, ten kernel threads slept the entire time, while ten kernel threads waited on terminal input. As a result, the application wait percent values would be 50% for SLEEP and 50% for TERM (that is, terminal IO).

In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. APP_MAJOR_FAULT ---------------------------------- The number of major page faults that required a disk IO for processes in this group during the interval. APP_MAJOR_FAULT_RATE ---------------------------------- The number of major page faults per second that required a disk IO for processes in this group during the interval. APP_MEM_QUEUE ---------------------------------- The average number of processes or kernel threads in this group blocked on memory (waiting for virtual memory disk accesses to complete) during the interval. This typically happens when processes or kernel threads are allocating a large amount of memory. It can also happen when processes or kernel threads access memory that has been paged out to disk (deactivated) because of overall memory pressure on the system. Note that large programs can block on VM disk access when they are initializing, bringing their text and data pages into memory. The Application QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues, within the context of a specific application. The Application WAIT PCT metrics, which are also based on block states, represent the percentage of processes or kernel threads that were alive on the system within the context of a specific application. These values will vary greatly depending on the application. No direct comparison is reasonable with the Global Queue metrics since they represent the average number of all processes or kernel threads that were alive on the system. As such, the Application WAIT PCT metrics cannot be summed or compared with global values easily. In addition, the sum of each Application WAIT PCT for all applications will not equal 100% since these values will vary greatly depending on the number of processes or kernel threads in each application. For example, the GBL_DISK_SUBSYSTEM_QUEUE values can be low, while the APP_DISK_SUBSYSTEM_WAIT_PCT values can be high. In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. APP_MEM_RES ---------------------------------- On Unix systems, this is the sum of the size (in KB) of resident memory for processes in this group that were alive at the end of the interval. This consists of text, data, stack, and shared memory regions. On HP-UX, since PROC_MEM_RES typically takes shared region references into account, this approximates the total resident (physical) memory consumed by all processes in this group. On all other Unix systems, this is the sum of the resident memory region sizes for all processes in this group. When the resident memory size for processes includes shared regions, such as shared memory and library text and data, the shared regions are counted multiple times in this sum. For example, if the application contains four processes that are attached to a 500MB shared memory region that is all resident in physical memory, then 2000MB is contributed towards the sum in this metric. As such, this metric can overestimate the resident memory being used by processes in this group when they share memory regions. Refer to the help text for PROC_MEM_RES for additional information. On Windows, this is the sum of the size (in KB) of the working sets for processes in this group during the interval. The working set counts memory pages referenced recently by the threads making up this group. Note that the size of the working set is often larger than the amount of pagefile space consumed. APP_MEM_UTIL ---------------------------------- On Unix systems, this is the approximate percentage of the system's physical memory used as resident memory by processes in this group that were alive at the end of the interval. This metric summarizes process private and shared memory in each application. On Windows, this is an estimate of the percentage of the system's physical memory allocated for working set memory by processes in this group during the interval. On HP-UX, this consists of text, data, stack, as well the process' portion of shared memory regions (such as, shared libraries, text segments, and shared data). The sum of the shared region pages is typically divided by the number of references. On Unix systems, each application's total resident memory is summed. This value is then divided by the summed total of all applications resident memory and then multiplied by the ratio of available user memory versus total physical memory to arrive at a calculated percentage of the total physical memory. It must be remembered, however, that this is a calculated metric that shows the approximate percentage of the physical memory used as resident memory by the processes in this application during the interval. On Windows, the sum of the working set sizes for each process in this group is kept as APP_MEM_RES. This value is divided by the sum of APP_MEM_RES for all applications defined on the system to come up with a ratio of this application's working set size to the total. This value is then multiplied by the ratio of available user memory versus total physical memory to arrive at a calculated percent of total physical memory. APP_MEM_VIRT ---------------------------------- On Unix systems, this is the sum (in KB) of virtual memory for processes in this group that were alive at the end of the interval. This consists of text, data, stack, and shared memory regions. On HP-UX, since PROC_MEM_VIRT typically takes shared region references into account, this approximates the total virtual memory consumed by all processes in this group. On all other Unix systems, this is the sum of the virtual memory region sizes for all processes in this group. When the virtual memory size for processes includes shared regions, such as shared memory and library text and data, the shared regions are counted multiple times in this sum. For example, if the application contains four processes that are attached to a 500MB shared memory region, then 2000MB is reported in this metric. As such, this metric can overestimate the virtual memory being used by processes in this group when they share memory regions. On Windows, this is the sum (in KB) of paging file space used for all processes in this group during the interval. Groups of processes may have working set sizes (APP_MEM_RES) larger than the size of their pagefile space. APP_MEM_WAIT_PCT ---------------------------------- The percentage of time processes or kernel threads in this group were blocked on memory (waiting for virtual memory disk accesses to complete) during the interval. A percentage of time spent in a wait state is calculated as the accumulated time kernel threads belonging to processes in this group spent waiting in this state, divided by accumulated alive time of kernel threads belonging to processes in this group during the interval. For example, assume an application has 20 kernel threads. During the interval, ten kernel threads slept the entire time, while ten kernel threads waited on terminal input. As a result, the application wait percent values would be 50% for SLEEP and 50% for TERM (that is, terminal IO). The Application QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues, within the context of a specific application. The Application WAIT PCT metrics, which are also based on block states, represent the percentage of processes or kernel threads that were alive on the system within the context of a specific application. These values will vary greatly depending on the application. No direct comparison is reasonable with the Global Queue metrics since they represent the average number of all processes or kernel threads that were alive on the system. As such, the Application WAIT PCT metrics cannot be summed or compared with global values easily. In addition, the sum of each Application WAIT PCT for all applications will not equal 100% since these values will vary greatly depending on the number of processes or kernel threads in each application. For example, the GBL_DISK_SUBSYSTEM_QUEUE values can be low, while the APP_DISK_SUBSYSTEM_WAIT_PCT values can be high. In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. APP_MINOR_FAULT ---------------------------------- The number of minor page faults satisfied in memory (a page was reclaimed from one of the free lists) for processes in this group during the interval. APP_MINOR_FAULT_RATE ---------------------------------- The number of minor page faults per second satisfied in memory (pages were reclaimed from one of the free lists) for processes in this group during the interval. APP_NAME ---------------------------------- The name of the application (up to 20 characters). This comes from the parm file where the applications are defined. The application called "other" captures all processes not aggregated into applications specifically defined in the parm file. In other words, if no applications are defined in the parm file, then all process data would be reflected in the "other" application. APP_NAME_PRM_GROUPNAME ---------------------------------- The PRM group name. The PRM group configuration is kept in the PRM configuration file. APP_NETWORK_SUBSYSTEM_QUEUE ---------------------------------- The average number of processes or kernel threads in this group were blocked on the network subsystem (waiting for their network activity to complete) during the interval. This is the sum of processes or kernel threads in the LAN, NFS, and RPC wait states. This does not include processes or kernel threads blocked on SOCKT (that is, socket) waits, as some processes or kernel threads sit idle in SOCKT waits for long periods. The Application QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues, within the context of a specific application. The Application WAIT PCT metrics, which are also based on block states, represent the percentage of processes or kernel threads that were alive on the system within the context of a specific application. These values will vary greatly depending on the application. No direct comparison is reasonable with the Global Queue metrics since they represent the average number of all processes or kernel threads that were alive on the system. As such, the Application WAIT PCT metrics cannot be summed or compared with global values easily. In addition, the sum of each Application WAIT PCT for all applications will not equal 100% since these values will vary greatly depending on the number of processes or kernel threads in each application.

In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. APP_NETWORK_SUBSYSTEM_WAIT_PCT ---------------------------------- The percentage of time processes or kernel threads in this group were blocked on the network subsystem (waiting for their network activity to complete) during the interval. This is the sum of processes or kernel threads in the LAN, NFS, and RPC wait states. This does not include processes or kernel threads blocked on SOCKT (that is, socket) waits, as some processes or kernel threads sit idle in SOCKT waits for long periods. This is calculated as the accumulated time that all processes or kernel threads in this group spent blocked on (LAN + NFS + RPC) divided by the interval time. A percentage of time spent in a wait state is calculated as the accumulated time kernel threads belonging to processes in this group spent waiting in this state, divided by accumulated alive time of kernel threads belonging to processes in this group during the interval. For example, assume an application has 20 kernel threads. During the interval, ten kernel threads slept the entire time, while ten kernel threads waited on terminal input. As a result, the application wait percent values would be 50% for SLEEP and 50% for TERM (that is, terminal IO). The Application QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues, within the context of a specific application. The Application WAIT PCT metrics, which are also based on block states, represent the percentage of processes or kernel threads that were alive on the system within the context of a specific application. These values will vary greatly depending on the application. No direct comparison is reasonable with the Global Queue metrics since they represent the average number of all processes or kernel threads that were alive on the system.

In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. APP_NUM ---------------------------------- The sequentially assigned number of this application. APP_OTHER_IO_QUEUE ---------------------------------- The average number of processes or kernel threads in this group that were blocked on "other IO" during the interval. "Other IO" includes all IO directed at a device (connected to the local computer) which is not a terminal or LAN. Examples of "other IO" devices are local printers, tapes, instruments, and disks. Time waiting for character (raw) IO to disks is included in this measurement. Time waiting for file system buffered IO to disks will typically been seen as IO or CACHE wait. Time waiting for IO to NFS disks is reported as NFS wait. This is calculated as the accumulated time that all processes or kernel threads in this group spent blocked on other IO divided by the interval time. The Application QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues, within the context of a specific application. The Application WAIT PCT metrics, which are also based on block states, represent the percentage of processes or kernel threads that were alive on the system within the context of a specific application. These values will vary greatly depending on the application.

In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. APP_PRI ---------------------------------- On Unix systems, this is the average priority of the processes in this group during the interval. On Windows, this is the average base priority of the processes in this group during the interval. APP_PRI_QUEUE ---------------------------------- The average number of processes or kernel threads in this group blocked on PRI (waiting for their priority to become high enough to get the CPU) during the interval. This is calculated as the accumulated time that all processes or kernel threads in this group spent blocked on PRI divided by the interval time. The Application QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues, within the context of a specific application. The Application WAIT PCT metrics, which are also based on block states, represent the percentage of processes or kernel threads that were alive on the system within the context of a specific application.

APP_PRI_STD_DEV ---------------------------------- The standard deviation of priorities of the processes in this group during the interval. This metric is available on HP-UX 10.20. APP_PRI_WAIT_PCT ---------------------------------- The percentage of time processes or kernel threads in this group were blocked on PRI (waiting for their priority to become high enough to get the CPU) during the interval. A percentage of time spent in a wait state is calculated as the accumulated time kernel threads belonging to processes in this group spent waiting in this state, divided by accumulated alive time of kernel threads belonging to processes in this group during the interval. For example, assume an application has 20 kernel threads. During the interval, ten kernel threads slept the entire time, while ten kernel threads waited on terminal input. As a result, the application wait percent values would be 50% for SLEEP and 50% for TERM (that is, terminal IO).

APP_PRM_CPUCAP_MODE ---------------------------------- The PRM CPU Cap Mode state on this system: 0 = PRM is not installed or not configured. 1 = CPU Cap Mode is not enabled (PRM CPU entitlements are in effect) 2 = CPU Cap Mode is enabled (The PRM CPU entitlements behave as caps or limits) APP_PRM_CPU_ENTITLEMENT ---------------------------------- The PRM CPU entitlement for this PRM Group ID entry as defined in the PRM configuration file. APP_PRM_CPU_TOTAL_UTIL_CUM ---------------------------------- The average CPU time per interval for processes in this group over the cumulative collection time, or since the last PRM configuration change. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. APP_PRM_DISK_STATE ---------------------------------- The PRM DISK state on this system: 0 = PRM is not installed or no disk specification 1 = reset (PRM is installed in reset condition or no disk specification) 2 = configured/disabled (The PRM disk management is configured) 3 = enabled/configured (The PRM disk management is enabled and volume groups are configured) 4 = enabled/unconfigured (The PRM disk management is enabled, however, no volume groups are configured) APP_PRM_GROUPID ---------------------------------- The PRM Group ID. The PRM group configuration is kept in the PRM configuration file. APP_PRM_INTERVAL_CUM ---------------------------------- The amount of time over the cumulative collection time.

APP_PRM_MEM_AVAIL ---------------------------------- PRM available memory is the amount of physical memory less the amount of memory reserved for the kernel and system processes running in the PRM_SYS group 0.

APP_PRM_MEM_STATE ---------------------------------- The PRM MEM state on this system: 0 = PRM is not installed or no memory specification 1 = reset (PRM is installed in reset condition or no memory specification) 2 = configured/disabled (The PRM memory scheduler is configured, but the standard HP-UX scheduler is in effect) 3 = enabled (The PRM memory scheduler is configured and in effect) APP_PRM_MEM_UPPERBOUND ---------------------------------- The PRM MEM upperbound for this PRM Group ID entry as defined in the PRM configuration file. APP_PRM_MEM_UTIL ---------------------------------- The percent of PRM memory used by processes (process private space plus a process' portion of shared memory) within the PRM groups during the interval. PRM available memory is the amount of physical memory less the amount of memory reserved for the kernel and system processes running in the PRM_SYS group 0. PRM available memory is a dynamic value that changes with system usage. APP_PRM_STATE ---------------------------------- The PRM CPU state on this system: 0 = PRM is not installed 1 = reset (PRM is configured with only the system group. The standard HP-UX CPU scheduler is in effect) 2 = configured/disabled (the PRM CPU scheduler is configured, but the standard HP-UX scheduler is in effect) 3 = enabled (the PRM CPU scheduler is configured and in effect) APP_PRM_SUSPENDED_PROC ---------------------------------- The number of processes within the PRM groups that were suspended during the interval. APP_PROC_RUN_TIME ---------------------------------- The average run time for processes in this group that completed during the interval. On non HP-UX systems, this metric is derived from sampled process data. Since the data for a process is not available after the process has died on this operating system, a process whose life is shorter than the sampling interval may not be seen when the samples are taken. Thus this metric may be slightly less than the actual value. Increasing the sampling frequency captures a more accurate count, but the overhead of collection may also rise. APP_SAMPLE ---------------------------------- The number of samples of process data that have been averaged or accumulated during this sample. APP_SEM_QUEUE ---------------------------------- The average number of processes or kernel threads in this group that were blocked on semaphores (waiting for their semaphore operations to complete) during the interval. The Application QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues, within the context of a specific application. The Application WAIT PCT metrics, which are also based on block states, represent the percentage of processes or kernel threads that were alive on the system within the context of a specific application. These values will vary greatly depending on the application. No direct comparison is reasonable with the Global Queue metrics since they represent the average number of all processes or kernel threads that were alive on the system. As such, the Application WAIT PCT metrics cannot be summed or compared with global values easily. In addition, the sum of each Application WAIT PCT for all applications will not equal 100% since these values will vary greatly depending on the number of processes or kernel threads in each application.

In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. APP_SEM_WAIT_PCT ---------------------------------- The percentage of time processes or kernel threads in this group were blocked on semaphores (waiting for their semaphore operations to complete) during the interval. A percentage of time spent in a wait state is calculated as the accumulated time kernel threads belonging to processes in this group spent waiting in this state, divided by accumulated alive time of kernel threads belonging to processes in this group during the interval. For example, assume an application has 20 kernel threads. During the interval, ten kernel threads slept the entire time, while ten kernel threads waited on terminal input. As a result, the application wait percent values would be 50% for SLEEP and 50% for TERM (that is, terminal IO).

APP_SLEEP_QUEUE ---------------------------------- The average number of processes or kernel threads in this group that were blocked on SLEEP (waiting to awaken from sleep system calls) during the interval. A process or kernel thread enters the SLEEP state by putting itself to sleep using system calls such as sleep, wait, pause, sigpause, sigsuspend, poll and select. The Application QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues, within the context of a specific application. The Application WAIT PCT metrics, which are also based on block states, represent the percentage of processes or kernel threads that were alive on the system within the context of a specific application. These values will vary greatly depending on the application. No direct comparison is reasonable with the Global Queue metrics since they represent the average number of all processes or kernel threads that were alive on the system.

A process or kernel thread enters the SLEEP state by putting itself to sleep using system calls such as sleep, wait, pause, sigpause, sigsuspend, poll and select. A percentage of time spent in a wait state is calculated as the accumulated time kernel threads belonging to processes in this group spent waiting in this state, divided by accumulated alive time of kernel threads belonging to processes in this group during the interval. For example, assume an application has 20 kernel threads. During the interval, ten kernel threads slept the entire time, while ten kernel threads waited on terminal input.

APP_TERM_IO_QUEUE ---------------------------------- The average number of processes or kernel threads in this group that were blocked on terminal IO (waiting for their terminal IO to complete) during the interval. This metric is available on HP-UX 10.20. APP_TERM_IO_WAIT_PCT ---------------------------------- The percentage of time processes or kernel threads in this group were blocked on terminal IO (waiting for terminal IO to complete) during the interval. A percentage of time spent in a wait state is calculated as the accumulated time kernel threads belonging to processes in this group spent waiting in this state, divided by accumulated alive time of kernel threads belonging to processes in this group during the interval. For example, assume an application has 20 kernel threads. During the interval, ten kernel threads slept the entire time, while ten kernel threads waited on terminal input. As a result, the application wait percent values would be 50% for SLEEP and 50% for TERM (that is, terminal IO). This metric is available on HP-UX 10.20. APP_TIME ---------------------------------- The end time of the measurement interval. BYCPU_ACTIVE ---------------------------------- Indicates whether or not this CPU is online. A CPU that is online is considered active. For HP-UX and certain versions of Linux, the sar(1M) command allows you to check the status of the system CPUs. For SUN and DEC, the commands psrinfo(1M) and psradm(1M) allow you to check or change the status of the system CPUs. For AIX, the pstat(1) command allows you to check the status of the system CPUs. BYCPU_CPU_CLOCK ---------------------------------- The clock speed of the CPU in the current slot. The clock speed is in MHz for the selected CPU. BYCPU_CPU_CSWITCH_TIME ---------------------------------- The time, in seconds, that this CPU was performing context switches during the interval. On HP-UX, this includes context switches that result in the execution of a different process and those caused by a process stopping, then resuming, with no other process running in the meantime. BYCPU_CPU_CSWITCH_TIME_CUM ---------------------------------- The time, in seconds, that this CPU was performing context switches over the cumulative collection time. On HP-UX, this includes context switches that result in the execution of a different process and those caused by a process stopping, then resuming, with no other process running in the meantime.

A rising rate of collisions versus outbound packets is an indication that the network is becoming increasingly congested. This metric does not currently include deferred packets. This data is not collected for non-broadcasting devices, such as loopback (lo), and is always zero. For HP-UX, this will be the same as the sum of the "Single Collision Frames", "Multiple Collision Frames", "Late Collisions", and "Excessive Collisions" values from the output of the "lanadmin" utility for the network interface. Remember that "lanadmin" reports cumulative counts. As of the HP-UX 11.0 release and beyond, "netstat -i" shows network activity on the logical level (IP) only. For most other Unix systems, this is the same as the sum of the "Coll" column from the "netstat -i" command ("collisions" from the "netstat -i -e" command on Linux) for a network device. See also netstat(1). AIX does not support the collision count for the ethernet interface. The collision count is supported for the token ring (tr) and loopback (lo) interfaces. For more information, please refer to the netstat(1) man page. Physical statistics are packets recorded by the network drivers. These numbers most likely will not be the same as the logical statistics. The values returned for the loopback interface will show "na" for the physical statistics since there is no network driver activity. Logical statistics are packets seen only by the Interface Protocol (IP) layer of the networking subsystem. Not all packets seen by IP will go out and come in through a network driver. An example is the loopback interface (127.0.0.1). Pings or other network generating commands (ftp, rlogin, and so forth) to 127.0.0.1 will not change physical driver statistics. Pings to IP addresses on remote systems will change physical driver statistics. This metric is updated at the sampling interval, regardless of the number of IP addresses on the system. BYNETIF_COLLISION_1_MIN_RATE ---------------------------------- The number of physical collisions per minute on the network interface during the interval. A rising rate of collisions versus outbound packets is an indication that the network is becoming increasingly congested. This metric does not currently include deferred packets.

BYNETIF_ERROR ---------------------------------- The number of physical errors that occurred on the network interface during the interval. An increasing number of errors may indicate a hardware problem in the network. On Unix systems, this data is not available for loop-back (lo) devices and is always zero.

Remember that "lanadmin" reports cumulative counts. As of the HP-UX 11.0 release and beyond, "netstat - i" shows network activity on the logical level (IP) only.

BYNETIF_LOGL_INTERVAL ---------------------------------- The amount of time in the interval. On systems with large numbers of Interface Protocol (IP) addresses, the measurement code now dynamically determines the interval for updating the BYNETIF_LOGL_* metrics. This reduces the collection overhead for these metrics in Glance and GPM. For the interval, it looks at how many IP addresses there are. The update interval for the BYNETIF_LOGL_* metrics is then set as follows: * For 1 - 20 IP addresses, the counters are updated at the normal sampling interval. * For 21 - 120 IP addresses, the counters are updated at an interval (in seconds) equal to the number of IP addresses. * For more than 120 IP addresses, the counters are updated every 120 seconds. For example, if Glance or GPM is run with 5-second update intervals on an 11.0 system with 200 IP addresses configured, the information shown in the Network detail screens will only change once every 2 minutes. The data reflects all activity over that time so no information is lost. BYNETIF_LOGL_INTERVAL_CUM ---------------------------------- The amount of time over the cumulative collection time.

BYNFS_HOSTNAME ---------------------------------- The Internet host name of this NFS entry. An NFS host is added if there are already NFS directories mounted or whenever any IO activity is seen, either server or client activity. It remains listed as long as the current midaemon program is running even if all NFS file systems are unmounted. A host on the network can act both as a client, or as a server at the same time.

BYNFS_LAST_PROC_ID ---------------------------------- The PID of the last process to generate or receive NFS traffic for this NFS host.

BYOP_NAME ---------------------------------- String mnemonic for the NFS operation. One of the following: For NFS Version 2 Name Operation/Action ------------------------------------ getattr Return the current attributes of a file. setattr Set the attributes of a file and returns the new attributes. lookup Return the attributes of a file. readlink Return the string in the symbolic link of a file. read Return data from a file. write Put data into a file. create Create a file. remove Remove a file. rename Give a file a new name. link Create a hard link to a file. symlink Create a symbolic link to a file. mkdir Create a directory. rmdir Remove a directory. readdir Read a directory entry. statfs Return mounted file system information. null Verify NFS service connections and timing. On HP-UX, no actual work done. writecache Flush the server write cache if a special write cache exists. Most systems use the file buffer cache and not a special server cache. Not used on HP-UX. root Find root file system handle (probably obsolete). Not used on HP-UX. For NFS Version 3 Name Operation/Action ------------------------------------ getattr Return the current attributes of a file. setattr Set the attributes of a file and returns the new attributes. lookup Return the attributes of a file. access Check access permissions of a user. readlink Return the string in the symbolic link of a file. read Return data from a file. write Put data into a file. create Create a file. mkdir Make a directory. symlink Create a symbolic link to a file. mknod Create a special device. remove Remove a file. rmdir Remove a directory. rename Give a file a new name. link Create a hard link to a file. readdir Read a directory entry. readdirplus Extended read of a directory entry. fsstat Get dynamic file system information. fsinfo Get static file system information. pathconf Retrieve POSIX information. commit Commit cached data on server to stable storage. null Verify NFS services. No actual work done. BYOP_SERVER_COUNT ---------------------------------- The number of current NFS operations that the local machine has processed as a NFS server during the interval. A host on the network can act both as a client, or as a server at the same time. BYOP_SERVER_COUNT_CUM ---------------------------------- The number of current NFS operations that the local machine has processed as a NFS server over the cumulative collection time. A host on the network can act both as a client, or as a server at the same time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. BYSWP_SWAP_PRI ---------------------------------- The priority of this swap device. This value is set by either the swapon(1M) command, or by the "pri=" field in /etc/fstab. On HP-UX, swap space is used by the lower value priorities first. Since device swap is faster than file system swap, it is advisable to have lower values for device swap. The legal values for priority range from 0 to 10. On HP-UX, the "memory" swap area has a priority of 11, which is one greater than the maximum legal priority value that a real swap device can be assigned. This indicates that using memory as a swap area is only done after all other swap resources have been exhausted. This is true in extreme cases of memory pressure forcing the kernel to swap the entire process to disk. In cases of process deactivation, the memory pseudo swap actually has the highest priority - deactivated pages are not moved - they are simply marked as deactivated and the space they occupy is considered pseudo swap. On Linux, swap space is used by the higher value priorities first. The legal values for priority range from 0 to 32767. The system assigns negative priority values if no priority is specified during the creation of swap area. See swapon(8) for details. BYSWP_SWAP_SPACE_AVAIL ---------------------------------- The capacity (in MB) for swapping in this swap area. On HP-UX, for "device" type swap, this value is constant. However, for "filesys" swap this value grows as needed. File system swap grows in units of "SWCHUNKS" x DEV_BSIZE bytes, which is typically 2MB. This metric is similar to the "AVAIL" parameters returned from /usr/sbin/swapinfo. For "memory" type swap, this value also grows as needed or as possible, given that any memory reserved for swap cannot be used for normal virtual memory. Note that this is potential swap space. Since swap is allocated in fixed (SWCHUNK) sizes, not all of this space may actually be usable. For example, on a 61 MB disk using 2 MB swap size allocations, 1 MB remains unusable and is considered wasted space. On SUN, this is the same as (blocks * .5)/1024, reported by the "swap -l" command. On AIX, this metric is set to "na" for inactive swap devices. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. BYSWP_SWAP_SPACE_NAME ---------------------------------- On Unix systems, this is the name of the device file or file system where the swap space is located. On HP-UX, part of the system's physical memory may be allocated as a pseudo-swap device. It is enabled by setting the "SWAPMEM_ON" kernel parameter to 1. On SunOS 5.X, part of the system's physical memory may be allocated as a pseudo-swap device. Also note, "/tmp" is usually configured as a memory based file system and is not used for swap space. Therefore, it will not be listed with the swap devices. This is noted because "df" uses the label "swap" for the "/tmp" file system which may be confusing. See tmpfs(7). BYSWP_SWAP_SPACE_USED ---------------------------------- The amount of swap space (in MB) used in this area. On HP-UX, this value is similar to the "USED" column returned by the /usr/sbin/swapinfo command. On SUN, "Used" indicates amount written to disk (or locked in memory), rather than reserved. Swap space is reserved (by decrementing a counter) when virtual memory for a program is created. This is the same as (blocks - free) * .5/1024, reported by the "swap -l" command. On SUN, global swap space is tracked through the operating system. Device swap space is tracked through the devices. For this reason, the amount of swap space used may differ between the global and by-device metrics. Sometimes pages that are marked to be swapped to disk by the operating system are never swapped. The operating system records this as used swap space, but the devices do not, since no physical IOs occur. (Metrics with the prefix "GBL" are global and metrics with the prefix "BYSWP" are by device.) On AIX, this metric is set to "na" for inactive swap devices. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. BYSWP_SWAP_TYPE ---------------------------------- The type of swap space allocated on the system. On HP-UX and SUN, types of swap space are device, file system ("filesys"), or memory. "Device" swap is accessed directly without going through the file system, and is therefore faster than "filesys" swap. "Filesys" swap can be to a local or NFS mounted swap file. "Memory" swap is space in the system's physical memory reserved for pseudo-swap for running processes. Using pseudo-swap means the pages are simply locked in memory rather than copied to a swap area. On SUN, note that "/tmp" is usually configured as a memory based file system and is not used for swap space. Therefore, it will not be listed with the swap devices, and "swap" or "tmpfs" will not be swap types. This is noted because "df" uses the label "swap" for the "/tmp" file system which may be confusing. See tmpfs(7). On AIX, "Device" swap is accessed directly without going through the file system. For "Device" swap, the device is specially allocated for swapping purpose only. The swap is often referred as paging to paging space. FSDETAIL_LABEL ---------------------------------- The type of entry this file system is associated with. It could be a device, partition, logical volume, or volume group. FSDETAIL_NAME ---------------------------------- The name of the device, partition, logical volume, or volume group this file system is associated with. FS_BLOCK_SIZE ---------------------------------- The maximum block size of this file system, in bytes. A value of "na" may be displayed if the file system is not mounted. If the product is restarted, these unmounted file systems are not displayed until remounted. FS_DEVNAME ---------------------------------- On Unix systems, this is the path name string of the current device. On Windows, this is the disk drive string of the current device. On HP-UX, this is the "fsname" parameter in the mount(1M) command. For NFS devices, this includes the name of the node exporting the file system. It is possible that a process may mount a device using the mount(2) system call. This call does not update the "/etc/mnttab" and its name is blank. This situation is rare, and should be corrected by syncer(1M). Note that once a device is mounted, its entry is displayed, even after the device is unmounted, until the midaemon process terminates. On SUN, this is the path name string of the current device, or "tmpfs" for memory based file systems. See tmpfs(7). FS_DEVNO ---------------------------------- On Unix systems, this is the major and minor number of the file system. On Windows, this is the unit number of the disk device on which the logical disk resides. FS_DIRNAME ---------------------------------- On Unix systems, this is the path name of the mount point of the file system. On Windows, this is the drive letter associated with the selected disk partition. On HP-UX, this is the path name of the mount point of the file system if the logical volume has a mounted file system. This is the directory parameter of the mount(1M) command for most entries. Exceptions are: * For lvm swap areas, this field contains "lvm swap device". * For logical volumes with no mounted file systems, this field contains "Raw Logical Volume" (relevant only to OVPA). On HP-UX, the file names are in the same order as shown in the "/usr/sbin/mount -p" command. File systems are not displayed until they exhibit IO activity once the midaemon has been started. Also, once a device is displayed, it continues to be displayed (even after the device is unmounted) until the midaemon process terminates. On SUN, only "UFS", "HSFS" and "TMPFS" file systems are listed. See mount(1M) and mnttab(4). "TMPFS" file systems are memory based filesystems and are listed here for convenience. See tmpfs(7). On AIX, see mount(1M) and filesystems(4). On OSF1, see mount(2). FS_FILE_IO_RATE ---------------------------------- The number of file system related physical IOs per second directed to this file system during the interval. This value is similar to the values returned by the vmstat -d command except that vmstat reports all IOs and does not break them out by file system. Also, vmstat reports IOs from the kernel's view, which may get broken down by the disk driver into multiple physical IOs. Since this metric reports values from the disk driver's point of view, it is more accurate than vmstat. FS_FILE_IO_RATE_CUM ---------------------------------- The average number of file IOs per second directed to this file system over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. This value is similar to the values returned by the vmstat -d command except that vmstat reports all IOs and does not break them out by file system. Also, vmstat reports IOs from the kernel's view, which may get broken down by the disk driver into multiple physical IOs. Since this metric reports values from the disk driver's point of view, it is more accurate than vmstat.

If the product is restarted, these unmounted file systems are not displayed until remounted. FS_MAX_SIZE ---------------------------------- Maximum number that this file system could obtain if full, in MB. Note that this is the user space capacity - it is the file system space accessible to non root users. On most Unix systems, the df command shows the total file system capacity which includes the extra file system space accessible to root users only. The equivalent fields to look at are "used" and "avail". For the target file system, to calculate the maximum size in MB, use FS Max Size = (used + avail)/1024 A value of "na" may be displayed if the file system is not mounted. If the product is restarted, these unmounted file systems are not displayed until remounted. On HP-UX, this metric is updated at 4 minute intervals to minimize collection overhead.

FS_SPACE_USED ---------------------------------- The amount of file system space in MBs that is being used. FS_SPACE_UTIL ---------------------------------- Percentage of the file system space in use during the interval. Note that this is the user space capacity - it is the file system space accessible to non root users. On most Unix systems, the df command shows the total file system capacity which includes the extra file system space accessible to root users only. A value of "na" may be displayed if the file system is not mounted. If the product is restarted, these unmounted file systems are not displayed until remounted.

FAT32 uses a 32-bit file allocation table entry. However, Windows 2000 reserves the first 4 bits of a FAT32 file allocation table entry, which means FAT32 has a theoretical maximum of 228 clusters.

FS_VM_IO_RATE_CUM ---------------------------------- The average number of virtual memory IOs per second directed to this file system over the cumulative collection time.

GBL_ACTIVE_CPU ---------------------------------- The number of CPUs online on the system. For HP-UX and certain versions of Linux, the sar(1M) command allows you to check the status of the system CPUs. For SUN and DEC, the commands psrinfo(1M) and psradm(1M) allow you to check or change the status of the system CPUs. For AIX, the pstat(1) command allows you to check the status of the system CPUs. GBL_ACTIVE_PROC ---------------------------------- An active process is one that exists and consumes some CPU time. GBL_ACTIVE_PROC is the sum of the alive-process- time/interval-time ratios of every process that is active (uses any CPU time) during an interval. The following diagram of a four second interval during which two processes exist on the system should be used to understand the above definition. Note the difference between active processes, which consume CPU time, and alive processes which merely exist on the system. ----------- Seconds ----------- 1 2 3 4 Proc ---- ---- ---- ---- ---- A live live live live B live/CPU live/CPU live dead Process A is alive for the entire four second interval but consumes no CPU. A's contribution to GBL_ALIVE_PROC is 4*1/4. A contributes 0*1/4 to GBL_ACTIVE_PROC. B's contribution to GBL_ALIVE_PROC is 3*1/4. B contributes 2*1/4 to GBL_ACTIVE_PROC. Thus, for this interval, GBL_ACTIVE_PROC equals 0.5 and GBL_ALIVE_PROC equals 1.75. Because a process may be alive but not active, GBL_ACTIVE_PROC will always be less than or equal to GBL_ALIVE_PROC. This metric is a good overall indicator of the workload of the system. An unusually large number of active processes could indicate a CPU bottleneck. To determine if the CPU is a bottleneck, compare this metric with GBL_CPU_TOTAL_UTIL and GBL_RUN_QUEUE. If GBL_CPU_TOTAL_UTIL is near 100 percent and GBL_RUN_QUEUE is greater than one, there is a bottleneck. On non HP-UX systems, this metric is derived from sampled process data. Since the data for a process is not available after the process has died on this operating system, a process whose life is shorter than the sampling interval may not be seen when the samples are taken. Thus this metric may be slightly less than the actual value. Increasing the sampling frequency captures a more accurate count, but the overhead of collection may also rise. GBL_ALIVE_PROC ---------------------------------- An alive process is one that exists on the system. GBL_ALIVE_PROC is the sum of the alive-process-time/interval- time ratios for every process. The following diagram of a four second interval during which two processes exist on the system should be used to understand the above definition. Note the difference between active processes, which consume CPU time, and alive processes which merely exist on the system. ----------- Seconds ----------- 1 2 3 4 Proc ---- ---- ---- ---- ---- A live live live live B live/CPU live/CPU live dead Process A is alive for the entire four second interval but consumes no CPU. A's contribution to GBL_ALIVE_PROC is 4*1/4. A contributes 0*1/4 to GBL_ACTIVE_PROC. B's contribution to GBL_ALIVE_PROC is 3*1/4. B contributes 2*1/4 to GBL_ACTIVE_PROC. Thus, for this interval, GBL_ACTIVE_PROC equals 0.5 and GBL_ALIVE_PROC equals 1.75. Because a process may be alive but not active, GBL_ACTIVE_PROC will always be less than or equal to GBL_ALIVE_PROC. On non HP-UX systems, this metric is derived from sampled process data. Since the data for a process is not available after the process has died on this operating system, a process whose life is shorter than the sampling interval may not be seen when the samples are taken. Thus this metric may be slightly less than the actual value. Increasing the sampling frequency captures a more accurate count, but the overhead of collection may also rise. GBL_BLANK ---------------------------------- A string of blanks. GBL_BOOT_TIME ---------------------------------- The date and time when the system was last booted. GBL_CACHE_QUEUE ---------------------------------- The average number of processes or kernel threads blocked on CACHE (waiting for the file system buffer cache to be updated) during the interval. Processes or kernel threads doing raw IO to a disk are not included in this measurement. As this number rises, it is an indication of a disk or memory bottleneck. This is calculated as the accumulated time that all processes or kernel threads spent blocked on CACHE divided by the interval time. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system. No direct comparison is reasonable with the Application WAIT PCT metrics since they represent percentages within the context of a specific application and cannot be summed or compared with global values easily. In addition, the sum of each Application WAIT PCT for all applications will not equal 100% since these values will vary greatly depending on the number of processes or kernel threads in each application. For example, the GBL_DISK_SUBSYSTEM_QUEUE values can be low, while the APP_DISK_SUBSYSTEM_WAIT_PCT values can be high. In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. GBL_CACHE_WAIT_PCT ---------------------------------- The percentage of time processes or kernel threads were blocked on cache (waiting for the file system buffer cache to be updated) during the interval. Processes or kernel threads doing raw IO to a disk are not included in this measurement. This is calculated as the accumulated time that all processes or kernel threads spent blocked on CACHE divided by the accumulated time that all processes or kernel threads were alive during the interval. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system.

In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. GBL_CACHE_WAIT_TIME ---------------------------------- The accumulated time, in seconds, that all processes or kernel threads were blocked on CACHE (waiting for the file system buffer cache to be updated) during the interval. Processes or kernel threads doing raw IO to a disk are not included in this measurement. GBL_CDFS_QUEUE ---------------------------------- The average number of processes or kernel threads blocked on CDFS (waiting for their Compact Disk file system IO to complete) during the interval. This is calculated as the accumulated time that all processes or kernel threads spent blocked on CDFS divided by the interval time. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system. No direct comparison is reasonable with the Application WAIT PCT metrics since they represent percentages within the context of a specific application and cannot be summed or compared with global values easily.

GBL_CDFS_WAIT_PCT ---------------------------------- The percentage of time processes or kernel threads were blocked on CDFS (waiting for their Compact Disk file system IO to complete) during the interval. This is calculated as the accumulated time that all processes or kernel threads spent blocked on CDFS divided by the accumulated time that all processes or kernel threads were alive during the interval. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system.

GBL_CDFS_WAIT_TIME ---------------------------------- The accumulated time, in seconds, that all processes or kernel threads were blocked on CDFS (waiting for their Compact Disk file system IO to complete) during the interval. GBL_COLLECTOR ---------------------------------- ASCII field containing collector name and version. The collector name will appear as either "SCOPE/xx V.UU.FF.LF" or "Coda RV.UU.FF.LF". xx identifies the platform; V = version, UU = update level, FF = fix level, and LF = lab fix id. For example, SCOPE/UX C.04.00.00; or Coda A.07.10.04. GBL_COMPLETED_PROC ---------------------------------- The number of processes that terminated during the interval. On non HP-UX systems, this metric is derived from sampled process data. Since the data for a process is not available after the process has died on this operating system, a process whose life is shorter than the sampling interval may not be seen when the samples are taken. Thus this metric may be slightly less than the actual value. Increasing the sampling frequency captures a more accurate count, but the overhead of collection may also rise.

This represents the usage of the total processing capacity available.

On a system with multiple CPUs, this metric is normalized. That is, the CPU used over all processors is divided by the number of processors online. This represents the usage of the total processing capacity available. GBL_CPU_QUEUE ---------------------------------- The average number of processes or kernel threads using the CPU plus all of those processes or kernel threads blocked on PRIORITY (waiting for their priority to become high enough to get the CPU) during the interval. This metric is an indicator of CPU demands among the active processes or kernel threads. To determine if the CPU is a bottleneck, compare this metric with GBL_CPU_TOTAL_UTIL. If GBL_CPU_TOTAL_UTIL is near 100 percent and GBL_CPU_QUEUE is greater than four, there is a high probability of a CPU bottleneck. This is calculated as (the CPU time used plus the accumulated time that all processes or kernel threads spent blocked on PRI (that is, priority)) divided by the interval time. The difference between this metric and GBL_PRI_QUEUE is that it includes the processes or kernel threads using the CPU, if any. HP-UX RUN/PRI/CPU Queue differences for multi-cpu systems: For example, let's assume we're using a system with eight processors. We start eight CPU intensive processes that consume almost all of the CPU resources. The approximate values shown for the CPU related queue metrics would be: GBL_RUN_QUEUE = 1.0 GBL_PRI_QUEUE = 0.1 GBL_CPU_QUEUE = 1.0 Assume we start an additional eight CPU intensive processes. The approximate values now shown are: GBL_RUN_QUEUE = 2.0 GBL_PRI_QUEUE = 8.0 GBL_CPU_QUEUE = 16.0 At this point, we have sixteen CPU intensive processes running on the eight processors. Keeping the definitions of the three queue metrics in mind, the run queue is 2 (that is, 16 / 8); the pri queue is 8 (only half of the processes can be active at any given time); and the cpu queue is 16 (half of the processes waiting in the cpu queue that are ready to run, plus one for each active process). This illustrates that the run queue is the average of the 1- minute load averages for all processors; the pri queue is the number of processes or kernel threads that are blocked on "PRI" (priority); and the cpu queue is the number of processes or kernel threads in the cpu queue that are ready to run, including the processes or kernel threads using the CPU. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system. No direct comparison is reasonable with the Application WAIT PCT metrics since they represent percentages within the context of a specific application and cannot be summed or compared with global values easily. In addition, the sum of each Application WAIT PCT for all applications will not equal 100% since these values will vary greatly depending on the number of processes or kernel threads in each application. For example, the GBL_DISK_SUBSYSTEM_QUEUE values can be low, while the APP_DISK_SUBSYSTEM_WAIT_PCT values can be high. In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. GBL_CPU_REALTIME_TIME ---------------------------------- The time, in seconds, that the CPU was in user mode at a realtime priority during the interval. Running at a realtime priority means that the process or kernel thread was run using the rtprio command or the rtprio system call to alter its priority. Realtime priorities range from zero to 127 and are absolute priorities, meaning the realtime process with the lowest priority runs as long as it wants to. Since this can have a huge impact on the system, the realtime CPU is tracked separately to make visible the effect of using realtime priorities. On a system with multiple CPUs, this metric is normalized. That is, the CPU used over all processors is divided by the number of processors online.

When a process requests services from the operating system with a system call, it switches into the machine's privileged protection mode and runs in system mode. This metric is a subset of the GBL_CPU_TOTAL_UTIL percentage.

On a system with multiple CPUs, this metric is normalized. That is, the CPU used over all processors is divided by the number of processors online. This represents the usage of the total processing capacity available. High system mode CPU percentages are normal for IO intensive applications. Abnormally high system mode CPU percentages can indicate that a hardware problem is causing a high interrupt rate. It can also indicate programs that are not calling system calls efficiently. On a logical system, this metric indicates the percentage of time the logical processor was in kernel mode during this interval. GBL_CPU_SYS_MODE_UTIL_CUM ---------------------------------- The percentage of time that the CPU was in system mode over the cumulative collection time. A process operates in either system mode (also called kernel mode on Unix or privileged mode on Windows) or user mode.

That is, the CPU used over all processors is divided by the number of processors online. This represents the usage of the total processing capacity available. GBL_CPU_TOTAL_UTIL + GBL_CPU_IDLE_UTIL = 100% This metric varies widely on most systems, depending on the workload. A consistently high CPU utilization can indicate a CPU bottleneck, especially when other indicators such as GBL_RUN_QUEUE and GBL_ACTIVE_PROC are also high. High CPU utilization can also occur on systems that are bottlenecked on memory, because the CPU spends more time paging and swapping. NOTE: On Windows, this metric may not equal the sum of the APP_CPU_TOTAL_UTIL metrics. Microsoft states that "this is expected behavior" because this GBL_CPU_TOTAL_UTIL metric is taken from the performance library Processor objects while the APP_CPU_TOTAL_UTIL metrics are taken from the Process objects. Microsoft states that there can be CPU time accounted for in the Processor system objects that may not be seen in the Process objects.

On HP-UX, this includes context switches that result in the execution of a different process and those caused by a process stopping, then resuming, with no other process running in the meantime. GBL_DISK_FS_BYTE ---------------------------------- The number of file system KBs (or MBs if specified) physically transferred to or from the disk during the interval. Only local disks are counted in this measurement. NFS devices are excluded. These are bytes transferred by user file system access and do not include bytes transferred via virtual memory IOs, system IOs (inode updates), or IOs relating to raw disk access. An exception is user files accessed via the mmap(2) call, which will not show their bytes transferred in this category. They appear under virtual memory bytes transferred.

GBL_DISK_LOGL_BYTE_RATE ---------------------------------- The number of KBs transferred per second via disk IO calls during the interval. Only local disks are counted in this measurement. NFS devices are excluded. On many Unix systems, logical disk IOs are measured by counting the read and write system calls that are directed to disk devices. Also counted are read and write system calls made indirectly through other system calls, including readv, recvfrom, recv, recvmsg, ipcrecvcn, recfrom, writev, send, sento, sendmsg, and ipcsend.

On many Unix systems, there are several reasons why logical IOs may not correspond with physical IOs. Logical IOs may not always result in a physical disk access, since the data may already reside in memory -- either in the buffer cache, or in virtual memory if the IO is to a memory mapped file. Several logical IOs may all map to the same physical page or block. In these two cases, logical IOs are greater than physical IOs. The reverse can also happen. A single logical write can cause a physical read to fetch the block to be updated from disk, and then cause a physical write to put it back on disk. A single logical IO can require more than one physical page or block, and these can be found on different disks. Mirrored disks further distort the relationship between logical and physical IO, since physical writes are doubled. GBL_DISK_LOGL_IO_CUM ---------------------------------- The number of logical IOs made over the cumulative collection time. Only local disks are counted in this measurement. NFS devices are excluded.

On SUN, this is the average number of logical block writes per second during the interval. Only local disks are counted in this measurement. NFS devices are excluded. On many Unix systems, logical disk IOs are measured by counting the write system calls that are directed to disk devices. Also counted are write system calls made indirectly through other system calls, including writev, recvfrom, recv, recvmsg, ipcrecvcn, recfrom, send, sento, sendmsg, and ipcsend. On many Unix systems, there are several reasons why logical IOs may not correspond with physical IOs. Logical IOs may not always result in a physical disk access, since the data may already reside in memory -- either in the buffer cache, or in virtual memory if the IO is to a memory mapped file. Several logical IOs may all map to the same physical page or block. In these two cases, logical IOs are greater than physical IOs. The reverse can also happen. A single logical write can cause a physical read to fetch the block to be updated from disk, and then cause a physical write to put it back on disk. A single logical IO can require more than one physical page or block, and these can be found on different disks. Mirrored disks further distort the relationship between logical and physical IO, since physical writes are doubled. GBL_DISK_LOGL_WRITE_RATE_CUM ---------------------------------- On most systems, this is the average number of logical writes per second of the total logical IOs over the cumulative collection time. On SUN, this is the average number of logical block writes per second of the total logical block IOs over the cumulative collection time. Only local disks are counted in this measurement. NFS devices are excluded. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last.

Mirrored disks further distort the relationship between logical and physical IO, since physical writes are doubled. GBL_DISK_PHYS_BYTE ---------------------------------- The number of KBs transferred to and from disks during the interval. The bytes for all types of physical IOs are counted. Only local disks are counted in this measurement. NFS devices are excluded. It is not directly related to the number of IOs, since IO requests can be of differing lengths. On Unix systems, this includes file system IO, virtual memory IO, and raw IO. On Windows, all types of physical IOs are counted. On SUN, if a CD drive is powered off, or no CD is inserted in the CD drive at boottime, the operating system does not provide performance data for that device. This can be determined by checking the "by-disk" data when provided in a product. If the CD drive has an entry in the list of active disks on a system, then data for that device is being collected. GBL_DISK_PHYS_BYTE_RATE ---------------------------------- The average number of KBs per second at which data was transferred to and from disks during the interval. The bytes for all types physical IOs are counted. Only local disks are counted in this measurement. NFS devices are excluded. This is a measure of the physical data transfer rate. It is not directly related to the number of IOs, since IO requests can be of differing lengths. This is an indicator of how much data is being transferred to and from disk devices. Large spikes in this metric can indicate a disk bottleneck. On Unix systems, all types of physical disk IOs are counted, including file system, virtual memory, and raw reads. On SUN, if a CD drive is powered off, or no CD is inserted in the CD drive at boottime, the operating system does not provide performance data for that device. This can be determined by checking the "by-disk" data when provided in a product. If the CD drive has an entry in the list of active disks on a system, then data for that device is being collected. GBL_DISK_PHYS_IO ---------------------------------- The number of physical IOs during the interval. Only local disks are counted in this measurement. NFS devices are excluded. On Unix systems, all types of physical disk IOs are counted, including file system IO, virtual memory IO and raw IO. On HP-UX, this is calculated as GBL_DISK_PHYS_IO = GBL_DISK_FS_IO + GBL_DISK_VM_IO + GBL_DISK_SYSTEM_IO + GBL_DISK_RAW_IO On SUN, if a CD drive is powered off, or no CD is inserted in the CD drive at boottime, the operating system does not provide performance data for that device.

GBL_DISK_PHYS_IO_CUM ---------------------------------- The total number of physical IOs over the cumulative collection time. Only local disks are counted in this measurement. NFS devices are excluded. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last.

On Unix systems, all types of physical disk IOs are counted, including file system IO, virtual memory IO and raw IO. On HP-UX, this is calculated as GBL_DISK_PHYS_IO_RATE = GBL_DISK_FS_IO_RATE + GBL_DISK_VM_IO_RATE + GBL_DISK_SYSTEM_IO_RATE + GBL_DISK_RAW_IO_RATE On SUN, if a CD drive is powered off, or no CD is inserted in the CD drive at boottime, the operating system does not provide performance data for that device. This can be determined by checking the "by-disk" data when provided in a product. If the CD drive has an entry in the list of active disks on a system, then data for that device is being collected. GBL_DISK_PHYS_IO_RATE_CUM ---------------------------------- The number of physical IOs per second over the cumulative collection time. Only local disks are counted in this measurement.

GBL_DISK_PHYS_READ ---------------------------------- The number of physical reads during the interval. Only local disks are counted in this measurement. NFS devices are excluded. On Unix systems, all types of physical disk reads are counted, including file system, virtual memory, and raw reads. On HP-UX, there are many reasons why there is not a direct correlation between the number of logical IOs and physical IOs. For example, small sequential logical reads may be satisfied from the buffer cache, resulting in fewer physical IOs than logical IOs. Conversely, large logical IOs or small random IOs may result in more physical than logical IOs. Logical volume mappings, logical disk mirroring, and disk striping also tend to remove any correlation. On HP-UX, this is calculated as GBL_DISK_PHYS_READ = GBL_DISK_FS_READ + GBL_DISK_VM_READ + GBL_DISK_SYSTEM_READ + GBL_DISK_RAW_READ On SUN, if a CD drive is powered off, or no CD is inserted in the CD drive at boottime, the operating system does not provide performance data for that device.

This can be determined by checking the "by-disk" data when provided in a product. If the CD drive has an entry in the list of active disks on a system, then data for that device is being collected. GBL_DISK_PHYS_READ_PCT ---------------------------------- The percentage of physical reads of total physical IO during the interval. Only local disks are counted in this measurement. NFS devices are excluded. On SUN, if a CD drive is powered off, or no CD is inserted in the CD drive at boottime, the operating system does not provide performance data for that device. This can be determined by checking the "by-disk" data when provided in a product. If the CD drive has an entry in the list of active disks on a system, then data for that device is being collected.

On Unix systems, all types of physical disk reads are counted, including file system, virtual memory, and raw reads. On HP-UX, this is calculated as GBL_DISK_PHYS_READ_RATE = GBL_DISK_FS_READ_RATE + GBL_DISK_VM_READ_RATE + GBL_DISK_SYSTEM_READ_RATE + GBL_DISK_RAW_READ_RATE On SUN, if a CD drive is powered off, or no CD is inserted in the CD drive at boottime, the operating system does not provide performance data for that device.

GBL_DISK_PHYS_WRITE ---------------------------------- The number of physical writes during the interval. Only local disks are counted in this measurement. NFS devices are excluded. On Unix systems, all types of physical disk writes are counted, including file system IO, virtual memory IO, and raw writes. On HP-UX, since this value is reported by the drivers, multiple physical requests that have been collapsed to a single physical operation (due to driver IO merging) are only counted once. On HP-UX, there are many reasons why there is not a direct correlation between logical IOs and physical IOs. For example, small logical writes may end up entirely in the buffer cache, and later generate fewer physical IOs when written to disk due to the larger IO size. Or conversely, small logical writes may require physical prefetching of the corresponding disk blocks before the data is merged and posted to disk. Logical volume mappings, logical disk mirroring, and disk striping also tend to remove any correlation. On HP-UX, this is calculated as GBL_DISK_PHYS_WRITE = GBL_DISK_FS_WRITE + GBL_DISK_VM_WRITE + GBL_DISK_SYSTEM_WRITE + GBL_DISK_RAW_WRITE On SUN, if a CD drive is powered off, or no CD is inserted in the CD drive at boottime, the operating system does not provide performance data for that device.

GBL_DISK_PHYS_WRITE_PCT ---------------------------------- The percentage of physical writes of total physical IO during the interval. Only local disks are counted in this measurement. NFS devices are excluded. On HP-UX, since this value is reported by the drivers, multiple physical requests that have been collapsed to a single physical operation (due to driver IO merging) are only counted once.

On HP-UX, since this value is reported by the drivers, multiple physical requests that have been collapsed to a single physical operation (due to driver IO merging) are only counted once. On HP-UX, this is calculated as GBL_DISK_PHYS_WRITE_RATE = GBL_DISK_FS_WRITE_RATE + GBL_DISK_VM_WRITE_RATE + GBL_DISK_SYSTEM_WRITE_RATE + GBL_DISK_RAW_WRITE_RATE On SUN, if a CD drive is powered off, or no CD is inserted in the CD drive at boottime, the operating system does not provide performance data for that device. This can be determined by checking the "by-disk" data when provided in a product. If the CD drive has an entry in the list of active disks on a system, then data for that device is being collected. GBL_DISK_PHYS_WRITE_RATE_CUM ---------------------------------- The number of physical writes per second over the cumulative collection time. Only local disks are counted in this measurement.

This can be determined by checking the "by-disk" data when provided in a product. If the CD drive has an entry in the list of active disks on a system, then data for that device is being collected. GBL_DISK_QUEUE ---------------------------------- The average number of processes or kernel threads blocked on disk (in a "queue" within the disk drivers waiting for their file system disk IO to complete) during the interval. Processes or kernel threads doing raw IO to a disk are not included in this measurement. As this number rises, it is an indication of a disk bottleneck. This is calculated as the accumulated time that all processes or kernel threads spent blocked on DISK divided by the interval time. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system. No direct comparison is reasonable with the Application WAIT PCT metrics since they represent percentages within the context of a specific application and cannot be summed or compared with global values easily. In addition, the sum of each Application WAIT PCT for all applications will not equal 100% since these values will vary greatly depending on the number of processes or kernel threads in each application. For example, the GBL_DISK_SUBSYSTEM_QUEUE values can be low, while the APP_DISK_SUBSYSTEM_WAIT_PCT values can be high. In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. GBL_DISK_RAW_BYTE ---------------------------------- The number of KBs (or MBs if specified) transferred to or from a raw disk during the interval. Only local disks are counted in this measurement.

GBL_DISK_RAW_IO ---------------------------------- The total number of raw reads and writes during the interval. Only local disks are counted in this measurement. NFS devices are excluded. On Sun, tape drive accesses are included in raw IOs, but not in physical IOs. To determine if raw IO is tape access versus disk access, compare the global physical disk accesses to the total raw, block, and vm IOs. If the totals are the same, the raw IO activity is to a disk, floppy, or CD drive. Check physical IO data for each individual disk device to isolate a device. If the totals are different, there is raw IO activity to a non-disk device like a tape drive. GBL_DISK_RAW_IO_CUM ---------------------------------- The total number of raw IOs over the cumulative collection time. Only local disks are counted in this measurement. NFS devices are excluded. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last.

If the totals are different, there is raw IO activity to a non-disk device like a tape drive. GBL_DISK_RAW_IO_PCT_CUM ---------------------------------- The percentage of physical raw IOs to total physical IOs made over the cumulative collection time. Only local disks are counted in this measurement. NFS devices are excluded. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last.

If the totals are different, there is raw IO activity to a non-disk device like a tape drive. GBL_DISK_REM_FS_BYTE ---------------------------------- The number of remote file system KBs (or MBs if specified) physically transferred to or from the remote machine during the interval. These are bytes transferred by user file system access and do not include bytes transferred via virtual memory IOs, system IOs (inode updates), or IOs relating to raw disk access. An exception is user files accessed via the mmap(2) call, which will not show their bytes transferred in this category. They appear under virtual memory bytes transferred. On HP-UX, remote file system IO typically occurs during client file system access of a network file system mounted on the server. A remote file system IO does not necessarily imply that a physical IO occurs on the remote (server) system. GBL_DISK_REM_FS_BYTE_CUM ---------------------------------- The number of remote file system KBs (or MBs if specified) transferred to or from the remote machine over the cumulative collection time. These are bytes transferred by user file system access and do not include bytes transferred via virtual memory IOs, system IOs (inode updates), or IOs relating to raw disk access.

The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. These are IOs for file system management (inode access or updates) and do not include IOs to user data. On HP-UX, remote file system IO typically occurs during client file system access of a network file system mounted on the server. A remote file system IO does not necessarily imply that a physical IO occurs on the remote (server) system. GBL_DISK_REM_VM_BYTE ---------------------------------- The number of remote virtual memory KBs (or MBs if specified) transferred to or from the remote machine during the interval. User file data transfers are not included in this metric unless they were done via the mmap(2) system call. On HP-UX, remote VM IO is typically seen on a client system that is paging in text from or paging out data pages to a server system. Paging in from the server system can occur when the client is loading a program which requires the text pages to be fetched from the server. Paging out occurs when client system data pages are swapped out to a remote swap device on the server system. GBL_DISK_REM_VM_BYTE_CUM ---------------------------------- The number of remote virtual memory KBs (or MBs if specified) transferred to or from the remote machine over the cumulative collection time. These are bytes transferred due to paging or swapping. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last.

GBL_DISK_REM_VM_IO_PCT ---------------------------------- The percentage of remote virtual memory IO requests of total remote physical IOs during the interval. IOs to user file data are not included in this metric unless they were done via the mmap(2) system call.

GBL_DISK_REM_VM_IO_PCT_CUM ---------------------------------- The percentage of remote virtual memory IOs of the total number of remote physical IOs over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last.

Paging out occurs when client system data pages are swapped out to a remote swap device on the server system. GBL_DISK_SUBSYSTEM_QUEUE ---------------------------------- The average number of processes or kernel threads blocked on the disk subsystem (in a "queue" waiting for their file system disk IO to complete) during the interval. This is the sum of processes or kernel threads in the DISK, INODE, CACHE and CDFS wait states. Processes or kernel threads doing raw IO to a disk are not included in this measurement. As this number rises, it is an indication of a disk bottleneck. This is calculated as the accumulated time that all processes or kernel threads spent blocked on (DISK + INODE + CACHE + CDFS) divided by the interval time. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system. No direct comparison is reasonable with the Application WAIT PCT metrics since they represent percentages within the context of a specific application and cannot be summed or compared with global values easily. In addition, the sum of each Application WAIT PCT for all applications will not equal 100% since these values will vary greatly depending on the number of processes or kernel threads in each application. For example, the GBL_DISK_SUBSYSTEM_QUEUE values can be low, while the APP_DISK_SUBSYSTEM_WAIT_PCT values can be high. In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. GBL_DISK_SUBSYSTEM_WAIT_PCT ---------------------------------- The percentage of time processes or kernel threads were blocked on the disk subsystem (waiting for their file system IOs to complete) during the interval. This is the sum of processes or kernel threads in the DISK, INODE, CACHE and CDFS wait states. This is calculated as the accumulated time that all processes or kernel threads spent blocked on (DISK + INODE + CACHE + CDFS) divided by the accumulated time that all processes or kernel threads were alive during the interval.

File system management IOs are the physical accesses required to obtain or update internal information about the file system structure (inode access). Accesses or updates to user data are not included in this metric.

GBL_DISK_UTIL ---------------------------------- On HP-UX, this is the average percentage of time during the interval that all disks had IO in progress from the point of view of the Operating System.

Only local disks are counted in this measurement. NFS devices are excluded. GBL_DISK_UTIL_PEAK ---------------------------------- The utilization of the busiest disk during the interval. On HP-UX, this is the percentage of time during the interval that the busiest disk device had IO in progress from the point of view of the Operating System. On all other systems, this is the percentage of time during the interval that the busiest disk was performing IO transfers. It is not an average utilization over all the disk devices. Only local disks are counted in this measurement. NFS devices are excluded. Some Linux kernels, typically 2.2 and older kernels, do not support the instrumentation needed to provide values for this metric. This metric will be "na" on the affected kernels. The "sar -d" command will also not be present on these systems. Distributions and OS releases that are known to be affected include: TurboLinux 7, SuSE 7.2, and Debian 3.0. A peak disk utilization of more than 50 percent often indicates a disk IO subsystem bottleneck situation. A bottleneck may not be in the physical disk drive itself, but elsewhere in the IO path. GBL_DISK_UTIL_PEAK_CUM ---------------------------------- The average utilization of the busiest disk in each interval over the cumulative collection time. Utilization is the percentage of time in use versus the time in the measurement interval. For each interval a different disk may be the busiest. Only local disks are counted in this measurement. NFS devices are excluded. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last.

GBL_DISK_VM_BYTE ---------------------------------- The number of virtual memory KBs (or MBs if specified) transferred to or from the disk during the interval. Only local disks are counted in this measurement. NFS devices are excluded. On HP-UX, the user file data transfers are not included in this metric unless they were done via the mmap(2) system call. GBL_DISK_VM_BYTE_CUM ---------------------------------- The number of virtual memory KBs (or MBs if specified) transferred to or from the disk over the cumulative collection time.

GBL_DISK_VM_IO ---------------------------------- The total number of virtual memory IOs made during the interval. Only local disks are counted in this measurement. NFS devices are excluded. On HP-UX, the IOs to user file data are not included in this metric unless they were done via the mmap(2) system call. On SUN, when a file is accessed, it is memory mapped by the operating system. Accesses generate virtual memory IOs. Reading a file generates block IOs as the file's inode information is cached. File writes are a combination of posting to memory mapped allocations (VM IOs) and posting updated inode information to disk (block IOs). On SUN, this metric is calculated by subtracting raw and block IOs from physical IOs. Tape drive accesses are included in the raw IOs, but not in the physical IOs. Therefore, when tape drive accesses are occurring on a system, all virtual memory and raw IO is counted as raw IO. For example, you may see heavy raw IO occurring during system backup. Raw IOs for disks are counted in the physical IOs. To determine if the raw IO is tape access versus disk access, compare the global physical disk accesses to the total of raw, block, and VM IOs. If the totals are the same, the raw IO activity is to a disk, floppy, or CD drive. Check physical IO data for each individual disk device to isolate a device. If the totals are different, there is raw IO activity to a non-disk device like a tape drive.

GBL_DISK_VM_WRITE_RATE_HIGH ---------------------------------- The highest number of virtual memory writes per second made during any interval over the cumulative collection time. Only local disks are counted in this measurement. NFS devices are excluded. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On HP-UX, the writes to user file data are not included in this metric unless they were done via the mmap(2) system call. On HP-UX, since this value is reported by the drivers, multiple physical requests that have been collapsed to a single physical operation (due to driver IO merging) are only counted once. GBL_DISK_WAIT_PCT ---------------------------------- The percentage of time processes or kernel threads were blocked on DISK (waiting in a disk driver for their disk IO to complete) during the interval. This is calculated as the accumulated time that all processes or kernel threads spent blocked on DISK divided by the accumulated time that all processes or kernel threads were alive during the interval. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system. No direct comparison is reasonable with the Application WAIT PCT metrics since they represent percentages within the context of a specific application and cannot be summed or compared with global values easily. In addition, the sum of each Application WAIT PCT for all applications will not equal 100% since these values will vary greatly depending on the number of processes or kernel threads in each application. For example, the GBL_DISK_SUBSYSTEM_QUEUE values can be low, while the APP_DISK_SUBSYSTEM_WAIT_PCT values can be high. In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. GBL_DISK_WAIT_TIME ---------------------------------- The accumulated time, in seconds, that all processes or kernel threads were blocked on DISK (waiting in a disk driver for their disk IO to complete) during the interval. GBL_FS_SPACE_UTIL_PEAK ---------------------------------- The percentage of occupied disk space to total disk space for the fullest file system found during the interval. Only locally mounted file systems are counted in this metric. This metric can be used as an indicator that at least one file system on the system is running out of disk space. On Unix systems, CDROM and PC file systems are also excluded. This metric can exceed 100 percent. This is because a portion of the file system space is reserved as a buffer and can only be used by root. If the root user has made the file system grow beyond the reserved buffer, the utilization will be greater than 100 percent. This is a dangerous situation since if the root user totally fills the file system, the system may crash. On Windows, CDROM file systems are also excluded. GBL_GMTOFFSET ---------------------------------- The difference, in minutes, between local time and GMT (Greenwich Mean Time). GBL_GRAPHICS_QUEUE ---------------------------------- The average number of processes or kernel threads blocked on graphics (waiting for their graphics operations to complete) during the interval. This is calculated as the accumulated time that all processes or kernel threads spent blocked on GRAPH (that is, graphics) divide by the interval time. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system. No direct comparison is reasonable with the Application WAIT PCT metrics since they represent percentages within the context of a specific application and cannot be summed or compared with global values easily.

GBL_GRAPHICS_WAIT_TIME ---------------------------------- The accumulated time, in seconds, that all processes or kernel threads were blocked on graphics (waiting for their graphics operations to complete) during the interval. GBL_INODE_QUEUE ---------------------------------- The average number of processes or kernel threads blocked on INODE (waiting for an inode to be updated or to become available) during the interval. This is calculated as the accumulated time that all processes or kernel threads spent blocked on INODE divided by the interval time. Inodes are used to store information about files within the file system. Every file has at least two inodes associated with it (one for the directory and one for the file itself). The information stored in an inode includes the owners, timestamps, size, and an array of indices used to translate logical block numbers to physical sector numbers. There is a separate inode maintained for every view of a file, so if two processes have the same file open, they both use the same directory inode, but separate inodes for the file. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system.

GBL_INODE_WAIT_PCT ---------------------------------- The percentage of time processes or kernel threads were blocked on INODE (waiting for an inode to be updated or to become available) during the interval. This is calculated as the accumulated time that all processes or kernel threads spent blocked on INODE divided by the accumulated time that all processes or kernel threads were alive during the interval.

GBL_INTERRUPT ---------------------------------- The number of IO interrupts during the interval. GBL_INTERRUPT_RATE ---------------------------------- The average number of IO interrupts per second during the interval. On HPUX and SUN this value includes clock interrupts. To get non-clock device interrupts, subtract clock interrupts from the value. GBL_INTERRUPT_RATE_CUM ---------------------------------- The average number of IO interrupts per second over the cumulative collection time. On HPUX and SUN this value includes clock interrupts. To get non-clock device interrupts, subtract clock interrupts from the value. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. GBL_INTERRUPT_RATE_HIGH ---------------------------------- The highest number of IO interrupts per second during any one interval over the cumulative collection time. On HPUX and SUN this value includes clock interrupts. To get non-clock device interrupts, subtract clock interrupts from the value. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. GBL_INTERVAL ---------------------------------- The amount of time in the interval. This measured interval is slightly larger than the desired or configured interval if the collection program is delayed by a higher priority process and cannot sample the data immediately. GBL_INTERVAL_CUM ---------------------------------- The amount of time over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. GBL_IPC_QUEUE ---------------------------------- The average number of processes or kernel threads blocked on InterProcess Communication (IPC) (waiting for their interprocess communication calls to complete) during the interval. This is calculated as the accumulated time that all processes or kernel threads spent blocked on IPC divided by the interval time. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system.

GBL_IPC_SUBSYSTEM_QUEUE ---------------------------------- The average number of processes or kernel threads blocked on the InterProcess Communication (IPC) subsystems (waiting for their interprocess communication activity to complete) during the interval. This is the sum of processes or kernel threads in the IPC, MSG, SEM, PIPE, SOCKT (that is, sockets) and STRMS (that is, streams IO) wait states. This is calculated as the accumulated time that all processes or kernel threads spent blocked on (IPC + MSG + SEM + PIPE + SOCKT + STRMS) divided by the interval time. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system.

This is the sum of processes or kernel threads in the IPC, MSG, SEM, PIPE, SOCKT (that is, sockets) and STRMS (that is, streams IO) wait states. This is calculated as the accumulated time that all processes or kernel threads spent blocked on (IPC + MSG + SEM + PIPE + SOCKT + STRMS) divided by the accumulated time that all processes or kernel threads were alive during the interval.

GBL_IPC_WAIT_TIME ---------------------------------- The accumulated time, in seconds, that all processes or kernel threads were blocked on InterProcess Communication (IPC) (waiting for their interprocess communication calls to complete) during the interval. GBL_JAVAARG ---------------------------------- This boolean value indicates whether the java class overloading mechanism is enabled or not. This metric will be set when the javaarg flag in the parm file is set. The metric affected by this setting is PROC_PROC_ARGV1. This setting is useful to construct parm file java application definitions using the argv1= keyword. GBL_JOBCTL_QUEUE ---------------------------------- The average number of processes or kernel threads blocked on job control (having been stopped with the job control facilities) during the interval. Job control waits include waiting at a debug breakpoint, as well as being blocked attempting to write (from background) to a terminal which has the "stty tostop" option set. This is calculated as the accumulated time that all processes or kernel threads spent blocked on job control divided by the interval time. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues.

GBL_LAN_QUEUE ---------------------------------- The average number of processes or kernel threads blocked on LAN (waiting for their IO over the LAN to complete) during the interval. This is calculated as the accumulated time that all processes or kernel threads spent blocked on LAN divided by the interval time. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues.

GBL_LOST_MI_TRACE_BUFFERS ---------------------------------- The number of trace buffers lost by the measurement processing daemon. On HP-UX systems, if this value is > 0, the measurement subsystem is not keeping up with the system events that generate traces. For other Unix systems, if this value is > 0, the measurement subsystem is not keeping up with the ARM API calls that generate traces. Note: The value reported for this metric will roll over to 0 once it crosses INTMAX. GBL_LS_ROLE ---------------------------------- Indicates whether OVPA is installed on Logical system or host or standalone system. This metric will be either "GUEST", "HOST" or "STAND". GBL_LS_TYPE ---------------------------------- The virtulization technology if applicable. The value of this metric is "HPVM" on HP-UX host, "LPAR" on AIX LPAR, "VMWr" on recognized VMWare ESX guest and VMWare ESX Server console, else "NoVM". In conjunction with GBL_LS_ROLE this metric could be used to identify the environment in which OVPA/Glance is running. For example, if GBL_LS_ROLE is "Guest" and GBL_LS_TYPE is "VMWr" then OVPA/Glance is running on a VMWare Guest. GBL_MACHINE ---------------------------------- On most Unix systems, this is a text string representing the type of computer. This is similar to what is returned by the command "uname -m". On AIX, this is a text string representing the model number of the computer. This is similar to what is returned by the command "uname -M". For example, "7043-150". On Windows, this is a text string representing the type of the computer. For example, "80686". GBL_MACHINE_MODEL ---------------------------------- The CPU model. This is similar to the information returned by the GBL_MACHINE metric and the uname command. However, this metric returns more information on some processors. On HP-UX, this is the same information returned by the model command. GBL_MEM_ACTIVE_VIRT ---------------------------------- The total virtual memory (in MBs unless otherwise specified) allocated for processes that are currently on the run queue or processes that have executed recently. This is the sum of the virtual memory sizes of the data and stack regions for these processes. Beginning with the OVPA 4.0 release, this metric is now reported in MBytes to better report the significant increases in system memory capacities. WARNING: This change in scale applies to this metric when logged by OVPA or displayed with GlancePlus for this release and beyond. However, the presentation of this metric recorded in legacy data (data logged with OVPA C.03 and previous releases), will remain in units of KBytes when viewed with extract or OVPM. GBL_MEM_ACTIVE_VIRT_UTIL ---------------------------------- The percentage of total virtual memory active at the end of the interval. Active virtual memory is the virtual memory associated with processes that are currently on the run queue or processes that have executed recently. This is the sum of the virtual memory sizes of the data and stack regions for these processes. GBL_MEM_AVAIL ---------------------------------- The amount of physical available memory in the system (in MBs unless otherwise specified). Beginning with the OVPA 4.0 release, this metric is now reported in MBytes to better report the significant increases in system memory capacities. WARNING: This change in scale applies to this metric when logged by OVPA or displayed with GlancePlus for this release and beyond. However, the presentation of this metric recorded in legacy data (data logged with OVPA C.03 and previous releases), will remain in units of KBytes when viewed with extract or OVPM. On Windows, memory resident operating system code and data is not included as available memory. GBL_MEM_CACHE ---------------------------------- The amount of physical memory (in MBs unless otherwise specified) used by the buffer cache during the interval. Beginning with the OVPA 4.0 release, this metric is now reported in MBytes to better report the significant increases in system memory capacities. WARNING: This change in scale applies to this metric when logged by OVPA or displayed with GlancePlus for this release and beyond. However, the presentation of this metric recorded in legacy data (data logged with OVPA C.03 and previous releases), will remain in units of KBytes when viewed with extract or OVPM. On HP-UX, the buffer cache is a memory pool used by the system to stage disk IO data for the driver. On SUN, this value is obtained by multiplying the system page size times the number of buffer headers (nbuf). For example, on a SPARCstation 10 the buffer size is usually (200 (page size buffers) * 4096 (bytes/page) = 800 KB). On SUN, the buffer cache is a memory pool used by the system to cache inode, indirect block and cylinder group related disk accesses. This is different from the traditional concept of a buffer cache that also holds file system data. On Solaris 5.X, as file data is cached, accesses to it show up as virtual memory IOs. File data caching occurs through memory mapping managed by the virtual memory system, not through the buffer cache. The "nbuf" value is dynamic, but it is very hard to create a situation where the memory cache metrics change, since most systems have more than adequate space for inode, indirect block, and cylinder group data caching. This cache is more heavily utilized on NFS file servers. On AIX, this value should be minimal since most disk IOs are done through memory mapped files. GBL_MEM_CACHE_HIT ---------------------------------- On HP-UX, the number of buffer cache reads resolved from the buffer cache (rather than going to disk) during the interval. Buffer cache reads can occur as a result of a logical read (for example, file read system call), a read generated by a client, a read-ahead on behalf of a logical read or a system procedure. On HP-UX, this metric is obtained by measuring the number of buffered read calls that were satisfied by the data that was in the file system buffer cache. Reads that are not in the buffer cache result in disk IO. raw IO and virtual memory IO, are not counted in this metric. On SUN, the number of physical reads resolved from memory (rather than going to disk) during the interval. This includes inode, indirect block and cylinder group related disk reads, plus file reads from files memory mapped by the virtual memory IO system. On AIX, the number of disk reads that were satisfied in the file system buffer cache (rather than going to disk) during the interval. On AIX, the traditional file system buffer cache is not normally used, since files are implicitly memory mapped and the access is through the virtual memory system rather than the buffer cache. However, if a file is read as a block device (e.g /dev/hdisk1), the file system buffer cache is used, making this metric meaningful in that situation. If no IO through the buffer cache occurs during the interval, this metric is 0. GBL_MEM_CACHE_HIT_CUM ---------------------------------- On HP-UX, the number of buffer cache reads resolved from the buffer cache (rather than going to disk) over the cumulative collection time. Buffer cache reads can occur as a result of a logical read (for example, file read system call), a read generated by a client, a read-ahead on behalf of a logical read or a system procedure. On HP-UX, this metric is obtained by measuring the number of buffered read calls that were satisfied by the data that was in the file system buffer cache. Reads that are not in the buffer cache result in disk IO. raw IO and virtual memory IO, are not counted in this metric. On SUN, the number of physical reads resolved from memory (rather than going to disk) over the cumulative collection time. This includes inode, indirect block and cylinder group related disk reads, plus file reads from files memory mapped by the virtual memory IO system. On AIX, the number of disk reads that were satisfied in the file system buffer cache (rather than going to disk) over the cumulative collection time. On AIX, the traditional file system buffer cache is not normally used, since files are implicitly memory mapped and the access is through the virtual memory system rather than the buffer cache. However, if a file is read as a block device (e.g /dev/hdisk1), the file system buffer cache is used, making this metric meaningful in that situation. If no IO through the buffer cache occurs during the interval, this metric is 0. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. GBL_MEM_CACHE_HIT_PCT ---------------------------------- On HP-UX, the percentage of buffer cache reads resolved from the buffer cache (rather than going to disk) during the interval. Buffer cache reads can occur as a result of a logical read (for example, file read system call), a read generated by a client, a read-ahead on behalf of a logical read or a system procedure. On HP-UX, this metric is obtained by measuring the number of buffered read calls that were satisfied by the data that was in the file system buffer cache. Reads to filesystem file buffers that are not in the buffer cache result in disk IO. Reads to raw IO and virtual memory IO (including memory mapped files), do not go through the filesystem buffer cache, and so are not relevant to this metric. On HP-UX, a low cache hit rate may indicate low efficiency of the buffer cache, either because applications have poor data locality or because the buffer cache is too small. Overly large buffer cache sizes can lead to a memory bottleneck. The buffer cache should be sized small enough so that pageouts do not occur even when the system is busy. However, in the case of VxFS, all memory-mapped IOs show up as page ins/page outs and are not a result of memory pressure. On AIX, the percentage of disk reads that were satisfied in the file system buffer cache (rather than going to disk) during the interval. On AIX, the traditional file system buffer cache is not normally used, since files are implicitly memory mapped and the access is through the virtual memory system rather than the buffer cache. However, if a file is read as a block device (e.g /dev/hdisk1), the file system buffer cache is used, making this metric meaningful in that situation. If no IO through the buffer cache occurs during the interval, this metric is 0. On the remaining Unix systems, this is the percentage of logical reads satisfied in memory (rather than going to disk) during the interval. This includes inode, indirect block and cylinder group related disk reads, plus file reads from files memory mapped by the virtual memory IO system. On Windows, this is the percentage of buffered reads satisfied in the buffer cache (rather than going to disk) during the interval. This metric is obtained by measuring the number of buffered read calls that were satisfied by the data that was in the system buffer cache. Reads that are not in the buffer cache result in disk IO. Unbuffered IO and virtual memory IO (including memory mapped files), are not counted in this metric. GBL_MEM_CACHE_HIT_PCT_CUM ---------------------------------- On HP-UX, this is the average percentage of buffer cache reads resolved from the buffer cache (rather than going to disk) over the cumulative collection time. Buffer cache reads can occur as a result of a logical read (for example, file read system call), a read generated by a client, a read- ahead on behalf of a logical read or a system procedure. On SUN, this is the percentage of physical reads that were satisfied in memory (rather than going to disk) over the cumulative collection time. This includes inode, indirect block and cylinder group related disk reads, plus file reads from files memory mapped by the virtual memory IO system. On AIX, this is the percentage of physical reads satisfied in the file system buffer cache (rather than going to disk) over the cumulative collection time. On AIX, the traditional file system buffer cache is not normally used, since files are implicitly memory mapped and the access is through the virtual memory system rather than the buffer cache. However, if a file is read as a block device (e.g /dev/hdisk1), the file system buffer cache is used, making this metric meaningful in that situation. If no IO through the buffer cache occurs during the interval, this metric is 0. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. GBL_MEM_CACHE_HIT_PCT_HIGH ---------------------------------- On HP-UX, this is the highest interval percentage of buffer cache reads resolved from the buffer cache (rather than going to disk) over the cumulative collection time. Buffer cache reads can occur as a result of a logical read (for example, file read system call), a read generated by a client, a read- ahead on behalf of a logical read or a system procedure.

On AIX, the traditional file system buffer cache is not normally used, since files are implicitly memory mapped and the access is through the virtual memory system rather than the buffer cache. However, if a file is read as a block device (e.g /dev/hdisk1), the file system buffer cache is used, making this metric meaningful in that situation.

GBL_MEM_CACHE_UTIL ---------------------------------- The percentage of physical memory used by the buffer cache during the interval. On HP-UX, the buffer cache is a memory pool used by the system to stage disk IO data for the driver. On SUN, this percentage is based on calculating the buffer cache size by multiplying the system page size times the number of buffer headers (nbuf). For example, on a SPARCstation 10 the buffer size is usually (200 (page size buffers) * 4096 (bytes/page) = 800 KB). On SUN, the buffer cache is a memory pool used by the system to cache inode, indirect block and cylinder group related disk accesses. This is different from the traditional concept of a buffer cache that also holds file system data. On Solaris 5.X, as file data is cached, accesses to it show up as virtual memory IOs. File data caching occurs through memory mapping managed by the virtual memory system, not through the buffer cache. The "nbuf" value is dynamic, but it is very hard to create a situation where the memory cache metrics change, since most systems have more than adequate space for inode, indirect block, and cylinder group data caching. This cache is more heavily utilized on NFS file servers. On AIX, this value should be minimal since most disk IOs are done through memory mapped files. On Windows the value reports 'copy read hit %' and 'Pin read hit %'. GBL_MEM_CACHE_WRITE_HIT ---------------------------------- The number of write cache hits - logical writes that did not result in physical IOs during the interval. A cache write hit occurs when a logical write request is issued to a disk file block that is already mapped in a buffer that is in a delayed write state. This metric gives an indication of how many physical IOs are eliminated as a result of buffering logical write requests. Physical IOs are eliminated in environments where asynchronous writes are done (see the O_SYNC flag in open(2)) to the same file blocks before being explicitly written to the disk or flushed to disk by the syncher process. Environments that attempt to minimize the chance of file system data loss by issuing synchronous writes or by using shorter syncer intervals will see fewer cache write hits. During a short interval, the number of physical writes can exceed the number of logical write requests. This would yield a negative number of "write hits". If this occurs in an interval, "na" will be returned. GBL_MEM_CACHE_WRITE_HIT_CUM ---------------------------------- The number of write cache hits - logical writes that did not result in physical IOs over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last.

GBL_MEM_CACHE_WRITE_HIT_PCT ---------------------------------- The percentage of logical disk writes that did not result in physical disk IOs during the interval. A cache write hit occurs when a logical write request is issued to a disk file block that is already mapped in a buffer that is in a delayed write state. This metric gives an indication of how many physical IOs are eliminated as a result of buffering logical write requests.

If this occurs in an interval, "na" will be returned. GBL_MEM_CACHE_WRITE_HIT_PCT_CUM ---------------------------------- The percentage of logical disk writes that did not result in physical disk IOs over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last.

Environments that attempt to minimize the chance of file system data loss by issuing synchronous writes or by using shorter syncer intervals will see fewer cache write hits. GBL_MEM_DNLC_HIT ---------------------------------- The number of times a pathname component was found in the directory name lookup cache (rather than requiring a disk read to find a file) during the interval. On HP-UX, the directory name lookup cache is used to minimize sequential searches through directory entries for pathname components during pathname to inode translations. Such translations are done whenever a file is accessed through its filename. The cache holds the inode cache table offset for recently referenced pathname components. Pathname components that exceed 15 characters are not cached. Any HP-UX system call that includes a path parameter can result in directory name lookup cache activity, including but not limited to system calls such as open, stat, exec, lstat, unlink. Each component of a path parameter is parsed and converted to an inode separately, therefore several dnlc hits per path are possible. High directory name cache hit rates on HP-UX will be seen on systems where pathname component requests are frequently repeated. For example, when users or applications work in the same directory where they repeatedly list or open the same files, cache hit rates will be high. Unusually low cache hit rates might be seen on HP-UX systems where users or applications access many different directories in no particular pattern. Low cache hit rates can also be an indicator of an underconfigured inode cache. When an inode cache is too small, the kernel will more frequently have to flush older inode cache and their corresponding directory name cache entries in order to make room for new inode cache entries. On HP-UX, the directory name lookup cache is static in size and is allocated in kernel memory. As a result, it is not affected by user memory constraints. The size of the cache is stored in the kernel variable "ncsize" and is not directly tunable by the system administrator; however, it can be changed indirectly by tuning other tables used in the formula to compute the "ncsize". The formula is: ncsize = MAX(((nproc+16+maxusers)+ 32+(2*npty)),ninode) Note that ncsize is always >= ninode which is the default size of the inode cache. This is because the directory name cache contains inode table offsets for each cached pathname component. On SUN, long file names (greater than 30 characters) are not cached and are a type of cache miss. "Enters", or cache data updates, are not included in this data. The DNLC size is: (maxusers * 17) + 90 GBL_MEM_DNLC_HIT_CUM ---------------------------------- The number of times a pathname component was found in the directory name lookup cache (rather than requiring a disk read to find a file) over the cumulative collection time.

File cache is a memory pool used by the system to stage disk IO data for the driver. On HP-UX, the file cache is a memory pool used by the system to stage disk IO data for the driver. On Linux, this metric is equal to 'cached' value of 'free -m' command output. GBL_MEM_FILE_PAGE_CACHE_UTIL ---------------------------------- The percentage of physical_memory used by the file cache during the interval. File cache is a memory pool used by the system to stage disk IO data for the driver. On HP-UX, the file cache is a memory pool used by the system to stage disk IO data for the driver. On Linux, this metric is derived from 'cached' value of 'free -m' command output. GBL_MEM_FREE ---------------------------------- The amount of memory not allocated (in MBs unless otherwise specified). As this value drops, the likelihood increases that swapping or paging out to disk may occur to satisfy new memory requests. Beginning with the OVPA 4.0 release, this metric is now reported in MBytes to better report the significant increases in system memory capacities. WARNING: This change in scale applies to this metric when logged by OVPA or displayed with GlancePlus for this release and beyond. However, the presentation of this metric recorded in legacy data (data logged with OVPA C.03 and previous releases), will remain in units of KBytes when viewed with extract or OVPM. On SUN, low values for this metric may not indicate a true memory shortage. This metric can be influenced by the VMM (Virtual Memory Management) system.

The clock hand algorithm is used to control page aging on the system. GBL_MEM_PG_SCAN_CUM ---------------------------------- The number of pages scanned by the pageout daemon (or by the Clock Hand on AIX) over the cumulative collection time.

GBL_MEM_PHYS ---------------------------------- The amount of physical memory in the system (in MBs unless otherwise specified). Beginning with the OVPA 4.0 release, this metric is now reported in MBytes to better report the significant increases in system memory capacities. WARNING: This change in scale applies to this metric when logged by OVPA or displayed with GlancePlus for this release and beyond. However, the presentation of this metric recorded in legacy data (data logged with OVPA C.03 and previous releases), will remain in units of KBytes when viewed with extract or OVPM. On HP-UX, banks with bad memory are not counted. Note that on some machines, the Processor Dependent Code (PDC) code uses the upper 1MB of memory and thus reports less than the actual physical memory of the system. Thus, on a system with 256MB of physical memory, this metric and dmesg(1M) might only report 267,386,880 bytes (255MB). This is all the physical memory that software on the machine can access. On Windows, this is the total memory available, which may be slightly less than the total amount of physical memory present in the system. This value is also reported in the Control Panel's About Windows NT help topic. On Linux, this is the amount of memory given by dmesg(1M). If the value is not available in kernel ring buffer, then the sum of system memory and available memory will be reported as physical memory. GBL_MEM_QUEUE ---------------------------------- The average number of processes or kernel threads blocked on memory (waiting for virtual memory disk accesses to complete) during the interval. This typically happens when processes or kernel threads are allocating a large amount of memory. It can also happen when processes or kernel threads access memory that has been paged out to disk (swap) because of overall memory pressure on the system. Note that large programs can block on VM disk access when they are initializing, bringing their text and data pages into memory. When this metric rises, it can be an indication of a memory bottleneck, especially if overall system memory utilization (GBL_MEM_UTIL) is near 100% and there is also swapout or page out activity. This is calculated as the accumulated time that all processes or kernel threads spent blocked on memory divided by the interval time. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system. No direct comparison is reasonable with the Application WAIT PCT metrics since they represent percentages within the context of a specific application and cannot be summed or compared with global values easily. In addition, the sum of each Application WAIT PCT for all applications will not equal 100% since these values will vary greatly depending on the number of processes or kernel threads in each application. For example, the GBL_DISK_SUBSYSTEM_QUEUE values can be low, while the APP_DISK_SUBSYSTEM_WAIT_PCT values can be high. In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. GBL_MEM_SWAP ---------------------------------- The total number of swap ins and swap outs (or deactivations and reactivations on HP-UX) during the interval. On AIX, swap metrics are equal to the corresponding page metrics. On HP-UX, process swapping was replaced by a combination of paging and deactivation. Process deactivation occurs when the system is thrashing or when the amount of free memory falls below a critical level. The swapper then marks certain processes for deactivation and removes them from the run queue. Pages within the associated memory regions are reused or paged out by the memory management vhand process in favor of pages belonging to processes that are not deactivated. Unlike traditional process swapping, deactivated memory pages may or may not be written out to the swap area, because a process could be reactivated before the paging occurs. To summarize, a process swap-out on HP-UX is a process deactivation. A swap-in is a reactivation of a deactivated process. Swap metrics that report swap-out bytes now represent bytes paged out to swap areas from deactivated regions. Because these pages are pushed out over time based on memory demands, these counts are much smaller than HP-UX 9.x counts where the entire process was written to the swap area when it was swapped-out. Likewise, swap-in bytes now represent bytes paged in as a result of reactivating a deactivated process and reading in any pages that were actually paged out to the swap area while the process was deactivated. GBL_MEM_SWAPIN ---------------------------------- The number of swap ins (or reactivations on HP-UX) during the interval. On AIX, swap metrics are equal to the corresponding page metrics. On HP-UX, this is the same as the "swap ins" value from the "vmstat -s" command. Remember that "vmstat -s" reports cumulative counts. On HP-UX, process swapping was replaced by a combination of paging and deactivation. Process deactivation occurs when the system is thrashing or when the amount of free memory falls below a critical level.

GBL_MEM_SWAPIN_BYTE ---------------------------------- The number of KBs transferred in from disk due to swap ins (or reactivations on HP-UX) during the interval. On AIX, swap metrics are equal to the corresponding page metrics. On HP-UX, process swapping was replaced by a combination of paging and deactivation. Process deactivation occurs when the system is thrashing or when the amount of free memory falls below a critical level.

GBL_MEM_SWAPIN_BYTE_RATE_HIGH ---------------------------------- The highest number of KBs per second transferred from disk due to swap ins (or reactivations on HP-UX) during any interval over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On AIX, swap metrics are equal to the corresponding page metrics. On HP-UX, process swapping was replaced by a combination of paging and deactivation. Process deactivation occurs when the system is thrashing or when the amount of free memory falls below a critical level. The swapper then marks certain processes for deactivation and removes them from the run queue. Pages within the associated memory regions are reused or paged out by the memory management vhand process in favor of pages belonging to processes that are not deactivated. Unlike traditional process swapping, deactivated memory pages may or may not be written out to the swap area, because a process could be reactivated before the paging occurs. To summarize, a process swap-out on HP-UX is a process deactivation. A swap-in is a reactivation of a deactivated process. Swap metrics that report swap-out bytes now represent bytes paged out to swap areas from deactivated regions.

However, the presentation of this metric recorded in legacy data (data logged with OVPA C.03 and previous releases), will remain in units of KBytes when viewed with extract or OVPM. On HP-UX 11.0, this metric does not include some kinds of dynamically allocated kernel memory. This has always been reported in the GBL_MEM_USER* metrics. On HP-UX 11.11 and beyond, this metric includes some kinds of dynamically allocated kernel memory.

On HP-UX and Linux this does not include filecache also. On HP-UX 11.0, this metric does not include some kinds of dynamically allocated kernel memory. This has always been reported in the GBL_MEM_USER* metrics. On HP-UX 11.11 and beyond, this metric includes some kinds of dynamically allocated kernel memory. GBL_MEM_USER ---------------------------------- The amount of physical memory (in MBs unless otherwise specified) allocated to user code and data at the end of the interval. User memory regions include code, heap, stack, and other data areas including shared memory. This does not include memory for buffer cache. On HP-UX and Linux this does not include filecache also. Beginning with the OVPA 4.0 release, this metric is now reported in MBytes to better report the significant increases in system memory capacities. WARNING: This change in scale applies to this metric when logged by OVPA or displayed with GlancePlus for this release and beyond. However, the presentation of this metric recorded in legacy data (data logged with OVPA C.03 and previous releases), will remain in units of KBytes when viewed with extract or OVPM. On HP-UX 11.0, this metric includes some kinds of dynamically allocated kernel memory. On HP-UX 11.11 and beyond, this metric does not include some kinds of dynamically allocated kernel memory. This is now reported in the GBL_MEM_SYS* metrics. Large fluctuations in this metric can be caused by programs which allocate large amounts of memory and then either release the memory or terminate. A slow continual increase in this metric may indicate a program with a memory leak. GBL_MEM_USER_UTIL ---------------------------------- The percent of physical memory allocated to user code and data at the end of the interval. This metric shows the percent of memory owned by user memory regions such as user code, heap, stack and other data areas including shared memory. This does not include memory for buffer cache. On HP-UX and Linux this does not include filecache also. On HP- UX 11.0, this metric includes some kinds of dynamically allocated kernel memory. On HP-UX 11.11 and beyond, this metric does not include some kinds of dynamically allocated kernel memory. This is now reported in the GBL_MEM_SYS* metrics. Large fluctuations in this metric can be caused by programs which allocate large amounts of memory and then either release the memory or terminate. A slow continual increase in this metric may indicate a program with a memory leak. GBL_MEM_UTIL ---------------------------------- The percentage of physical memory in use during the interval. This includes system memory (occupied by the kernel), buffer cache and user memory. On HP-UX, this calculation is done using the byte values for physical memory and used memory, and is therefore more accurate than comparing the reported kilobyte values for physical memory and used memory. On SUN, high values for this metric may not indicate a true memory shortage. This metric can be influenced by the VMM (Virtual Memory Management) system. GBL_MEM_UTIL_CUM ---------------------------------- The average percentage of physical memory in use over the cumulative collection time. This includes system memory (occupied by the kernel), buffer cache and user memory. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. GBL_MEM_UTIL_HIGH ---------------------------------- The highest percentage of physical memory in use in any interval over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. GBL_MEM_VIRT ---------------------------------- The total private virtual memory (in MBs unless otherwise specified) at the end of the interval. This is the sum of the virtual allocation of private data and stack regions for all processes. Beginning with the OVPA 4.0 release, this metric is now reported in MBytes to better report the significant increases in system memory capacities. WARNING: This change in scale applies to this metric when logged by OVPA or displayed with GlancePlus for this release and beyond. However, the presentation of this metric recorded in legacy data (data logged with OVPA C.03 and previous releases), will remain in units of KBytes when viewed with extract or OVPM. GBL_MEM_WAIT_PCT ---------------------------------- The percentage of time processes or kernel threads were blocked on VM (waiting for virtual memory resources to become available) during the interval. This is calculated as the accumulated time that all processes or kernel threads spent blocked on VM divided by the accumulated time that all processes or kernel threads were alive during the interval. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system. No direct comparison is reasonable with the Application WAIT PCT metrics since they represent percentages within the context of a specific application and cannot be summed or compared with global values easily. In addition, the sum of each Application WAIT PCT for all applications will not equal 100% since these values will vary greatly depending on the number of processes or kernel threads in each application. For example, the GBL_DISK_SUBSYSTEM_QUEUE values can be low, while the APP_DISK_SUBSYSTEM_WAIT_PCT values can be high. In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem.

GBL_MI_LOST_PROC_CUM ---------------------------------- The total number of processes the measurement layer has lost the ability to update during the cumulative collection interval. GBL_MI_PROC_ENTRIES ---------------------------------- The number of process entries allocated in the midaemon shared memory area. GBL_MI_THREAD_ENTRIES ---------------------------------- The number of thread entries allocated in the midaemon shared memory area. GBL_MSG_QUEUE ---------------------------------- The average number of processes or kernel threads blocked on messages (waiting for their message queue calls to complete) during the interval. This is calculated as the accumulated time that all processes or kernel threads spent blocked on MESG (that is, messages) divided by the interval time. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system. No direct comparison is reasonable with the Application WAIT PCT metrics since they represent percentages within the context of a specific application and cannot be summed or compared with global values easily. In addition, the sum of each Application WAIT PCT for all applications will not equal 100% since these values will vary greatly depending on the number of processes or kernel threads in each application.

GBL_MSG_WAIT_TIME ---------------------------------- The accumulated time, in seconds, that all processes or kernel threads were blocked on messages (waiting for their message queue calls to complete) during the interval. GBL_NETWORK_SUBSYSTEM_QUEUE ---------------------------------- The average number of processes or kernel threads blocked on the network subsystem (waiting for their network activity to complete) during the interval. This is the sum of processes or kernel threads in the LAN, NFS, and RPC wait states. This does not include processes or kernel threads blocked on SOCKT (that is, sockets) waits, as some processes or kernel threads sit idle in SOCKT waits for long periods. This is calculated as the accumulated time that all processes or kernel threads spent blocked on (LAN + NFS + RPC) divided by the interval time. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system.

GBL_NETWORK_SUBSYSTEM_WAIT_PCT ---------------------------------- The percentage of time processes or kernel threads were blocked on the network subsystem (waiting for their network activity to complete) during the interval. This is the sum of processes or kernel threads in the LAN, NFS, and RPC wait states. This does not include processes or kernel threads blocked on SOCKT (that is, sockets) waits, as some processes or kernel threads sit idle in SOCKT waits for long periods. This is calculated as the accumulated time that all processes or kernel threads spent blocked on (LAN + NFS + RPC) divided by the accumulated time that all processes or kernel threads were alive during the interval.

GBL_NET_COLLISION ---------------------------------- The number of collisions that occurred on all network interfaces during the interval. A rising rate of collisions versus outbound packets is an indication that the network is becoming increasingly congested. This metric does not include deferred packets. For HP-UX, this will be the same as the sum of the "Single Collision Frames", "Multiple Collision Frames", "Late Collisions", and "Excessive Collisions" values from the output of the "lanadmin" utility for the network interface. Remember that "lanadmin" reports cumulative counts. As of the HP-UX 11.0 release and beyond, "netstat -i" shows network activity on the logical level (IP) only. For all other Unix systems, this is the same as the sum of the "Coll" column from the "netstat -i" command ("collisions" from the "netstat -i -e" command on Linux) for a network device. See also netstat(1). AIX does not support the collision count for the ethernet interface. The collision count is supported for the token ring (tr) and loopback (lo) interfaces. For more information, please refer to the netstat(1) man page. This metric is updated at the sampling interval, regardless of the number of IP addresses on the system. GBL_NET_COLLISION_1_MIN_RATE ---------------------------------- The number of collisions per minute on all network interfaces during the interval. This metric does not include deferred packets.

The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system. No direct comparison is reasonable with the Application WAIT PCT metrics since they represent percentages within the context of a specific application and cannot be summed or compared with global values easily. In addition, the sum of each Application WAIT PCT for all applications will not equal 100% since these values will vary greatly depending on the number of processes or kernel threads in each application. For example, the GBL_DISK_SUBSYSTEM_QUEUE values can be low, while the APP_DISK_SUBSYSTEM_WAIT_PCT values can be high. In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem.

The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. A percentage greater than 50 indicates that this machine is acting more as a server for others. A percentage less than 50 indicates this machine is acting more as a client. NFS IOs include reads and writes from successful calls to getattr, setattr, lookup, read, readdir, readlink, write, and writecache.

This number represents physical IOs received by the server in contrast to a call which is an attempt to initiate these operations. Each computer can operate as both a NFS server, and as an NFS client. NFS IOs include reads and writes from successful calls to getattr, setattr, lookup, read, readdir, readlink, write, and writecache.

NFS IOs include reads and writes from successful calls to getattr, setattr, lookup, read, readdir, readlink, write, and writecache. GBL_NFS_SERVER_READ_BYTE_RATE ---------------------------------- The number of KBs per second the system sent as a NFS server responding to NFS read operations from client nodes during the interval.

GBL_NFS_SERVER_SERVICE_TIME ---------------------------------- The time, in seconds, spent for the NFS server to process the client's operations during the interval. This includes all of the time from the point that the operations are received to the point where a reply is sent back to the client, which includes software overhead and any local disk IOs. This is not an average service time per operation; it is the total service time for all operations processed during the interval. GBL_NFS_SERVER_SERVICE_TIME_CUM ---------------------------------- The time, in seconds, spent for the NFS server to process the client's operations over the cumulative collection time. This includes all of the time from the point that the operations are received to the point where a reply is sent back to the client, which includes software overhead and any local disk IOs. This is not an average service time per operation; it is the total service time for all operations processed. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last.

GBL_NFS_WAIT_PCT ---------------------------------- The percentage of time processes or kernel threads were blocked on NFS (waiting for their network file system IO to complete) during the interval. This is calculated as the accumulated time that all processes or kernel threads spent blocked on NFS divided by the accumulated time that all processes or kernel threads were alive during the interval. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system. No direct comparison is reasonable with the Application WAIT PCT metrics since they represent percentages within the context of a specific application and cannot be summed or compared with global values easily. In addition, the sum of each Application WAIT PCT for all applications will not equal 100% since these values will vary greatly depending on the number of processes or kernel threads in each application. For example, the GBL_DISK_SUBSYSTEM_QUEUE values can be low, while the APP_DISK_SUBSYSTEM_WAIT_PCT values can be high. In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. GBL_NFS_WAIT_TIME ---------------------------------- The accumulated time, in seconds, that all processes or kernel threads were blocked on NFS (waiting for their network file system IO to complete) during the interval. GBL_NODENAME ---------------------------------- On Unix systems, this is the name of the computer as returned by the command "uname -n" (that is, the string returned from the "hostname" program). On Windows, this is the name of the computer as returned by GetComputerName. GBL_NUM_ACTIVE_LS ---------------------------------- This indicates the number of LS hosted in a system that are active . If OVPA is installed in a guest or in a standalone system this value will be 0. GBL_NUM_APP ---------------------------------- The number of applications defined in the parm file plus one (for "other"). The application called "other" captures all other processes not defined in the parm file. You can define up to 128 applications. GBL_NUM_APP_PRM ---------------------------------- The number of PRM groups configured - 1 per PRM Group ID. HP-UX supports up to 64 unique PRM Groups. GBL_NUM_CPU ---------------------------------- The number of physical CPUs on the system. This includes all CPUs, either online or offline. For HP-UX and certain versions of Linux, the sar(1M) command allows you to check the status of the system CPUs. For SUN and DEC, the commands psrinfo(1M) and psradm(1M) allow you to check or change the status of the system CPUs. On a logical system, this metric indicates the number of virtual CPUs configured. When hardware threads are enabled, this metric indicates the number of logical processors. GBL_NUM_CPU_CORE ---------------------------------- This metric provides the number of CPU cores on a physical system. GBL_NUM_DISK ---------------------------------- The number of disks on the system. Only local disk devices are counted in this metric. On HP-UX, this is a count of the number of disks on the system that have ever had activity over the cumulative collection time. GBL_NUM_HBA ---------------------------------- The number of Host Bus adaptors on the system. GBL_NUM_LS ---------------------------------- This indicates the number of LS hosted in a system. If OVPA is installed in a guest or in a standalone system this value will be 0. GBL_NUM_NETWORK ---------------------------------- The number of network interfaces on the system. This includes the loopback interface. On certain platforms, this also include FDDI, Hyperfabric, ATM, Serial Software interfaces such as SLIP or PPP, and Wide Area Network interfaces (WAN) such as ISDN or X.25. The "netstat -i" command also displays the list of network interfaces on the system. GBL_NUM_SWAP ---------------------------------- The number of configured swap areas. GBL_NUM_TAPE ---------------------------------- The number of Tape devices attached to the system. GBL_NUM_TT ---------------------------------- The number of unique Transaction Tracker (TT) transactions that have been registered on this system. GBL_NUM_USER ---------------------------------- The number of users logged in at the time of the interval sample. This is the same as the command "who | wc -l". For Unix systems, the information for this metric comes from the utmp file which is updated by the login command. For more information, read the man page for utmp. Some applications may create users on the system without using login and updating the utmp file. These users are not reflected in this count. This metric can be a general indicator of system usage. In a networked environment, however, users may maintain inactive logins on several systems. On Windows, the information for this metric comes from the Server Sessions counter in the Performance Libraries Server object. It is a count of the number of users using this machine as a file server. GBL_NUM_VG ---------------------------------- The number of available volume groups. GBL_OSKERNELTYPE ---------------------------------- This indicates the word size of the current kernel on the system. Some hardware can load the 64-bit kernel or the 32- bit kernel. GBL_OSKERNELTYPE_INT ---------------------------------- This indicates the word size of the current kernel on the system. Some hardware can load the 64-bit kernel or the 32- bit kernel. GBL_OSNAME ---------------------------------- A string representing the name of the operating system. On Unix systems, this is the same as the output from the "uname -s" command. GBL_OSRELEASE ---------------------------------- The current release of the operating system. On most Unix systems, this is same as the output from the "uname -r" command. On AIX, this is the actual patch level of the operating system. This is similar to what is returned by the command "lslpp -l bos.rte" as the most recent level of the COMMITTED Base OS Runtime. For example, "5.2.0". GBL_OSVERSION ---------------------------------- A string representing the version of the operating system. This is the same as the output from the "uname -v" command. This string is limited to 20 characters, and as a result, the complete version name might be truncated. On Windows, this is a string representing the service pack installed on the operating system. GBL_OTHER_IO_QUEUE ---------------------------------- The average number of processes or kernel threads blocked on "other IO" during the interval. "Other IO" includes all IO directed at a device (connected to the local computer) which is not a terminal or LAN. Examples of "other IO" devices are local printers, tapes, instruments, and disks. Time waiting for character (raw) IO to disks is included in this measurement. Time waiting for file system buffered IO to disks will typically been seen as IO or CACHE wait. Time waiting for IO to NFS disks is reported as NFS wait. This is calculated as the accumulated time that all processes or kernel threads spent blocked on other IO divided by the interval time. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system. No direct comparison is reasonable with the Application WAIT PCT metrics since they represent percentages within the context of a specific application and cannot be summed or compared with global values easily. In addition, the sum of each Application WAIT PCT for all applications will not equal 100% since these values will vary greatly depending on the number of processes or kernel threads in each application. For example, the GBL_DISK_SUBSYSTEM_QUEUE values can be low, while the APP_DISK_SUBSYSTEM_WAIT_PCT values can be high. In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. GBL_OTHER_IO_WAIT_PCT ---------------------------------- The percentage of time processes or kernel threads were blocked on "other IO" during the interval.

Time waiting for IO to NFS disks is reported as NFS wait. GBL_OTHER_QUEUE ---------------------------------- The average number of processes or kernel threads blocked on other (unknown) activities during the interval. This includes processes or kernel threads that were started and subsequently suspended before the midaemon was started and have not been resumed, or the block state is unknown. This is calculated as the accumulated time that all processes or kernel threads spent blocked on OTHER divided by the interval time. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system.

This includes processes or kernel threads that were started and subsequently suspended before the midaemon was started and have not been resumed, or the block state is unknown. This is calculated as the accumulated time that all processes or kernel threads spent blocked on OTHER divided by the accumulated time that all processes or kernel threads were alive during the interval. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system.

GBL_OTHER_WAIT_TIME ---------------------------------- The accumulated time, in seconds, that all processes or kernel threads were blocked on other (unknown) activities during the interval. This includes processes or kernel threads that were started and subsequently suspended before the midaemon was started and have not been resumed, or the block state is unknown. GBL_PIPE_QUEUE ---------------------------------- The average number of processes or kernel threads blocked on PIPE (waiting for pipe communication to complete) during the interval. This is calculated as the accumulated time that all processes or kernel threads spent blocked on PIPE divided by the interval time. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system.

GBL_PIPE_WAIT_TIME ---------------------------------- The accumulated time, in seconds, that all processes or kernel threads were blocked on PIPE (waiting for pipe communication to complete) during the interval. GBL_PRI_QUEUE ---------------------------------- The average number of processes or kernel threads blocked on PRI (waiting for their priority to become high enough to get the CPU) during the interval. To determine if the CPU is a bottleneck, compare this metric with GBL_CPU_TOTAL_UTIL. If GBL_CPU_TOTAL_UTIL is near 100 percent and GBL_PRI_QUEUE is greater than three, there is a high probability of a CPU bottleneck. This is calculated as the accumulated time that all processes or kernel threads spent blocked on PRI divided by the interval time. HP-UX RUN/PRI/CPU Queue differences for multi-cpu systems: For example, let's assume we're using a system with eight processors. We start eight CPU intensive processes that consume almost all of the CPU resources. The approximate values shown for the CPU related queue metrics would be: GBL_RUN_QUEUE = 1.0 GBL_PRI_QUEUE = 0.1 GBL_CPU_QUEUE = 1.0 Assume we start an additional eight CPU intensive processes. The approximate values now shown are: GBL_RUN_QUEUE = 2.0 GBL_PRI_QUEUE = 8.0 GBL_CPU_QUEUE = 16.0 At this point, we have sixteen CPU intensive processes running on the eight processors. Keeping the definitions of the three queue metrics in mind, the run queue is 2 (that is, 16 / 8); the pri queue is 8 (only half of the processes can be active at any given time); and the cpu queue is 16 (half of the processes waiting in the cpu queue that are ready to run, plus one for each active process). This illustrates that the run queue is the average of the 1- minute load averages for all processors; the pri queue is the number of processes or kernel threads that are blocked on "PRI" (priority); and the cpu queue is the number of processes or kernel threads in the cpu queue that are ready to run, including the processes or kernel threads using the CPU. Note that if the value for GBL_PRI_QUEUE greatly exceeds the value for GBL_RUN_QUEUE, this may be a side-effect of the measurement interface having lost trace data. In this case, check the value of the GBL_LOST_MI_TRACE_BUFFERS metric. If there has been buffer loss, you can correct the value of GBL_PRI_QUEUE by restarting the midaemon and the performance tools. You can use the /opt/perf/bin/midaemon -T command to force immediate shutdown of the measurement interface. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system. No direct comparison is reasonable with the Application WAIT PCT metrics since they represent percentages within the context of a specific application and cannot be summed or compared with global values easily.

GBL_PRI_WAIT_PCT ---------------------------------- The percentage of time processes or kernel threads were blocked on PRI (waiting for their priority to become high enough to get the CPU) during the interval. This is calculated as the accumulated time that all processes or kernel threads spent blocked on PRI divided by the accumulated time that all processes or kernel threads were alive during the interval.

GBL_PRI_WAIT_TIME ---------------------------------- The accumulated time, in seconds, that all processes or kernel threads were blocked on PRI (waiting for their priority to become high enough to get the CPU) during the interval. GBL_PRM_MEM_UTIL ---------------------------------- The total percent of memory used by processes within the PRM groups during the interval. This does not include system processes (processes attached to PRM group 0). GBL_PROC_RUN_TIME ---------------------------------- The average run time, in seconds, for processes that terminated during the interval. GBL_PROC_SAMPLE ---------------------------------- The number of process data samples that have been averaged into global metrics (such as GBL_ACTIVE_PROC) that are based on process samples. GBL_RPC_QUEUE ---------------------------------- The average number of processes or kernel threads blocked on RPC (waiting for their remote procedure calls to complete) during the interval. This is calculated as the accumulated time that all processes or kernel threads spent blocked on RPC divided by the interval time. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system. No direct comparison is reasonable with the Application WAIT PCT metrics since they represent percentages within the context of a specific application and cannot be summed or compared with global values easily. In addition, the sum of each Application WAIT PCT for all applications will not equal 100% since these values will vary greatly depending on the number of processes or kernel threads in each application.

In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. GBL_RPC_WAIT_PCT ---------------------------------- The percentage of time processes or kernel threads were blocked on RPC (waiting for their remote procedure calls to complete) during the interval. This is calculated as the accumulated time that all processes or kernel threads spent blocked on RPC divided by the accumulated time that all processes or kernel threads were alive during the interval. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues.

GBL_RPC_WAIT_TIME ---------------------------------- The accumulated time, in seconds, that all processes or kernel threads were blocked on RPC (waiting for their remote procedure calls to complete) during the interval. GBL_RUN_QUEUE ---------------------------------- On Unix systems, the value shown is the 1-minute load average for all processors. On HP-UX, the load average is the average number of processes waiting for CPU per processor, whereas on other Unix systems, the load average is the total number of runnable and running threads summed over all processors during the interval. In other words, for non HP-UX systems, this metric correlates to the number of threads executing on and waiting for any processor. On Windows, this is approximately the average Processor Queue Length during the interval. On Unix systems, GBL_RUN_QUEUE will typically be a small number. Larger than normal values for this metric indicate CPU contention among processes. This CPU bottleneck is also normally indicated by 100 percent GBL_CPU_TOTAL_UTIL. It may be OK to have GBL_CPU_TOTAL_UTIL be 100 percent if no other processes are waiting for the CPU. However, if GBL_CPU_TOTAL_UTIL is 100 percent and GBL_RUN_QUEUE is greater than the number of processors, it indicates a CPU bottleneck. On Windows, the Processor Queue reflects a count of process threads which are ready to execute. A thread is ready to execute (in the Ready state) when the only resource it is waiting on is the processor. The Windows operating system itself has many system threads which intermittently use small amounts of processor time. Several low priority threads intermittently wake up and execute for very short intervals. Depending on when the collection process samples this queue, there may be none or several of these low-priority threads trying to execute. Therefore, even on an otherwise quiescent system, the Processor Queue Length can be high. High values for this metric during intervals where the overall CPU utilization (gbl_cpu_total_util) is low do not indicate a performance bottleneck. Relatively high values for this metric during intervals where the overall CPU utilization is near 100% can indicate a CPU performance bottleneck. HP-UX RUN/PRI/CPU Queue differences for multi-cpu systems: For example, let's assume we're using a system with eight processors. We start eight CPU intensive processes that consume almost all of the CPU resources. The approximate values shown for the CPU related queue metrics would be: GBL_RUN_QUEUE = 1.0 GBL_PRI_QUEUE = 0.1 GBL_CPU_QUEUE = 1.0 Assume we start an additional eight CPU intensive processes. The approximate values now shown are: GBL_RUN_QUEUE = 2.0 GBL_PRI_QUEUE = 8.0 GBL_CPU_QUEUE = 16.0 At this point, we have sixteen CPU intensive processes running on the eight processors. Keeping the definitions of the three queue metrics in mind, the run queue is 2 (that is, 16 / 8); the pri queue is 8 (only half of the processes can be active at any given time); and the cpu queue is 16 (half of the processes waiting in the cpu queue that are ready to run, plus one for each active process). This illustrates that the run queue is the average of the 1- minute load averages for all processors; the pri queue is the number of processes or kernel threads that are blocked on "PRI" (priority); and the cpu queue is the number of processes or kernel threads in the cpu queue that are ready to run, including the processes or kernel threads using the CPU. GBL_RUN_QUEUE_CUM ---------------------------------- On the non HP-UX systems, this is the average number of "runnable" processes over the cumulative collection time. On HP-UX, this is the average number of "runnable" processes or kernel threads over all processors over the cumulative collection time. The value shown for the run queue represents the average of the 1-minute load averages for all processors. On Windows, this is approximately the average Processor Queue Length over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. In this case, this metric is a cumulative average of data that was collected as an average. This metric is derived from GBL_RUN_QUEUE. HP-UX RUN/PRI/CPU Queue differences for multi-cpu systems: For example, let's assume we're using a system with eight processors. We start eight CPU intensive processes that consume almost all of the CPU resources. The approximate values shown for the CPU related queue metrics would be: GBL_RUN_QUEUE = 1.0 GBL_PRI_QUEUE = 0.1 GBL_CPU_QUEUE = 1.0 Assume we start an additional eight CPU intensive processes.

This illustrates that the run queue is the average of the 1- minute load averages for all processors; the pri queue is the number of processes or kernel threads that are blocked on "PRI" (priority); and the cpu queue is the number of processes or kernel threads in the cpu queue that are ready to run, including the processes or kernel threads using the CPU. GBL_RUN_QUEUE_HIGH ---------------------------------- On the non HP-UX systems, this is the highest value of the load average during any interval over the cumulative collection time. On HP-UX, this is the highest average number of "runnable" processes or kernel threads over all processors during any interval over the cumulative collection time. The value shown for the run queue represents the average of the 1- minute load averages for all processors. GBL_SAMPLE ---------------------------------- The number of data samples (intervals) that have occurred over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. GBL_SEM_QUEUE ---------------------------------- The average number of processes or kernel threads blocked on semaphores (waiting for their semaphore operations to complete) during the interval. This is calculated as the accumulated time that all processes or kernel threads spent blocked on PRI (that is, priority) divided by the interval time. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system. No direct comparison is reasonable with the Application WAIT PCT metrics since they represent percentages within the context of a specific application and cannot be summed or compared with global values easily. In addition, the sum of each Application WAIT PCT for all applications will not equal 100% since these values will vary greatly depending on the number of processes or kernel threads in each application. For example, the GBL_DISK_SUBSYSTEM_QUEUE values can be low, while the APP_DISK_SUBSYSTEM_WAIT_PCT values can be high. In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. GBL_SEM_WAIT_PCT ---------------------------------- The percentage of time processes or kernel threads were blocked on semaphores (waiting on a semaphore operation) during the interval. This is calculated as the accumulated time that all processes or kernel threads spent blocked on SEM (that is, semaphores) divided by the accumulated time that all processes or kernel threads were alive during the interval. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system. No direct comparison is reasonable with the Application WAIT PCT metrics since they represent percentages within the context of a specific application and cannot be summed or compared with global values easily. In addition, the sum of each Application WAIT PCT for all applications will not equal 100% since these values will vary greatly depending on the number of processes or kernel threads in each application. For example, the GBL_DISK_SUBSYSTEM_QUEUE values can be low, while the APP_DISK_SUBSYSTEM_WAIT_PCT values can be high. In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. GBL_SEM_WAIT_TIME ---------------------------------- The accumulated time, in seconds, that all processes or kernel threads were blocked on semaphores (waiting for their semaphore operations to complete) during the interval. GBL_SERIALNO ---------------------------------- On HP-UX, this is the ID number of the computer as returned by the command "uname -i". If this value is not available, an empty string is returned. On SUN, this is the ASCII representation of the hardware- specific serial number. This is printed in hexadecimal as presented by the "hostid" command when possible. If that is not possible, the decimal format is provided instead. On AIX, this is the machine ID number as returned by the command "uname -m". This number has the form xxyyyyyymmss. For the RISC System/6000, "xx" position is always 00. The "yyyyyy" positions contain the unique ID number for the central processing unit (cpu). While "mm" represents the model number, and "ss" is the submodel number (always 00). On Linux, this is the ASCII representation of the hardware- specific serial number, as returned by the command "hostid". GBL_SLEEP_QUEUE ---------------------------------- The average number of processes or kernel threads blocked on SLEEP (waiting to awaken from sleep system calls) during the interval. A process or kernel thread enters the SLEEP state by putting itself to sleep using system calls such as sleep, wait, pause, sigpause, sigsuspend, poll and select. This is calculated as the accumulated time that all processes or kernel threads spent blocked on SLEEP divided by the interval time. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system. No direct comparison is reasonable with the Application WAIT PCT metrics since they represent percentages within the context of a specific application and cannot be summed or compared with global values easily. In addition, the sum of each Application WAIT PCT for all applications will not equal 100% since these values will vary greatly depending on the number of processes or kernel threads in each application. For example, the GBL_DISK_SUBSYSTEM_QUEUE values can be low, while the APP_DISK_SUBSYSTEM_WAIT_PCT values can be high. In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. GBL_SLEEP_WAIT_PCT ---------------------------------- The percentage of time processes or kernel threads were blocked on SLEEP (waiting to awaken from sleep system calls) during the interval. A process or kernel thread enters the SLEEP state by putting itself to sleep using system calls such as sleep, wait, pause, sigpause, sigsuspend, poll and select. This is calculated as the accumulated time that all processes or kernel threads spent blocked on SLEEP divided by the accumulated time that all processes or kernel threads were alive during the interval. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system. No direct comparison is reasonable with the Application WAIT PCT metrics since they represent percentages within the context of a specific application and cannot be summed or compared with global values easily.

In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. GBL_SLEEP_WAIT_TIME ---------------------------------- The accumulated time, in seconds, that all processes or kernel threads were blocked on SLEEP (waiting to awaken from sleep system calls) during the interval. A process or kernel thread enters the SLEEP state by putting itself to sleep using system calls such as sleep, wait, pause, sigpause, sigsuspend, poll and select. GBL_SOCKET_QUEUE ---------------------------------- The average number of processes or kernel threads blocked on sockets (waiting for their IO to complete) during the interval. This is calculated as the accumulated time that all processes or kernel threads spent blocked on SOCKT (that is, sockets) divided by the interval time. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system. No direct comparison is reasonable with the Application WAIT PCT metrics since they represent percentages within the context of a specific application and cannot be summed or compared with global values easily. In addition, the sum of each Application WAIT PCT for all applications will not equal 100% since these values will vary greatly depending on the number of processes or kernel threads in each application. For example, the GBL_DISK_SUBSYSTEM_QUEUE values can be low, while the APP_DISK_SUBSYSTEM_WAIT_PCT values can be high. In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. GBL_SOCKET_WAIT_PCT ---------------------------------- The percentage of time processes or kernel threads were blocked on sockets (waiting for their IO to complete) during the interval. This is calculated as the accumulated time that all processes or kernel threads spent blocked on SOCKT (that is, sockets) divided by the accumulated time that all processes or threads were alive during the interval. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system. No direct comparison is reasonable with the Application WAIT PCT metrics since they represent percentages within the context of a specific application and cannot be summed or compared with global values easily.

In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. GBL_SOCKET_WAIT_TIME ---------------------------------- The accumulated time, in seconds, that all processes or kernel threads were blocked on sockets (waiting for their IO to complete) during the interval. GBL_STARTDATE ---------------------------------- The date that the collector started. GBL_STARTED_PROC ---------------------------------- The number of processes that started during the interval. GBL_STARTED_PROC_RATE ---------------------------------- The number of processes that started per second during the interval. GBL_STARTTIME ---------------------------------- The time of day that the collector started. GBL_STATDATE ---------------------------------- The date at the end of the interval, based on local time. GBL_STATTIME ---------------------------------- An ASCII string representing the time at the end of the interval, based on local time. GBL_STREAM_QUEUE ---------------------------------- The average number of processes or kernel threads blocked on streams IO (waiting for a streams IO operation to complete) during the interval. This is calculated as the accumulated time that all processes or kernel threads spent blocked on STRMS (that is, streams IO) divided by the interval time. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system. No direct comparison is reasonable with the Application WAIT PCT metrics since they represent percentages within the context of a specific application and cannot be summed or compared with global values easily. In addition, the sum of each Application WAIT PCT for all applications will not equal 100% since these values will vary greatly depending on the number of processes or kernel threads in each application. For example, the GBL_DISK_SUBSYSTEM_QUEUE values can be low, while the APP_DISK_SUBSYSTEM_WAIT_PCT values can be high. In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. GBL_STREAM_WAIT_PCT ---------------------------------- The percentage of time processes or kernel threads were blocked on streams IO (waiting for a streams IO operation to complete) during the interval. This is calculated as the accumulated time that all processes or kernel threads spent blocked on STRMS (that is, streams IO) divided by the accumulated time that all processes or kernel threads were alive during the interval. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system. No direct comparison is reasonable with the Application WAIT PCT metrics since they represent percentages within the context of a specific application and cannot be summed or compared with global values easily. In addition, the sum of each Application WAIT PCT for all applications will not equal 100% since these values will vary greatly depending on the number of processes or kernel threads in each application. For example, the GBL_DISK_SUBSYSTEM_QUEUE values can be low, while the APP_DISK_SUBSYSTEM_WAIT_PCT values can be high. In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. GBL_STREAM_WAIT_TIME ---------------------------------- The accumulated time, in seconds, that all processes or kernel threads were blocked on streams IO (waiting for a streams IO operation to complete) during the interval. GBL_SWAP_RESERVED_ONLY_UTIL ---------------------------------- The percentage of available swap space reserved (for currently running programs), but not yet used. Swap space must be reserved (but not allocated) before virtual memory can be created. Swap space locations are actually assigned (used) when a page is actually written to disk. On HP-UX, when compared to the "swapinfo -mt" command results, this is calculated as: Util = ((USED: reserve) / (AVAIL: total)) * 100 On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. GBL_SWAP_SPACE_AVAIL ---------------------------------- The total amount of potential swap space, in MB. On HP-UX, this is the sum of the device swap areas enabled by the swapon command, the allocated size of any file system swap areas, and the allocated size of pseudo swap in memory if enabled. Note that this is potential swap space. This is the same as (AVAIL: total) as reported by the "swapinfo -mt" command. On SUN, this is the total amount of swap space available from the physical backing store devices (disks) plus the amount currently available from main memory. This is the same as (used + available) /1024, reported by the "swap -s" command. On Linux, this is same as (Swap: total) as reported by the "free -m" command. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. GBL_SWAP_SPACE_AVAIL_KB ---------------------------------- The total amount of potential swap space, in KB. On HP-UX, this is the sum of the device swap areas enabled by the swapon command, the allocated size of any file system swap areas, and the allocated size of pseudo swap in memory if enabled. Note that this is potential swap space. Since swap is allocated in fixed (SWCHUNK) sizes, not all of this space may actually be usable. For example, on a 61MB disk using 2 MB swap size allocations, 1 MB remains unusable and is considered wasted space. On HP-UX, this is the same as (AVAIL: total) as reported by the "swapinfo -t" command. On SUN, this is the total amount of swap space available from the physical backing store devices (disks) plus the amount currently available from main memory. This is the same as (used + available)/1024, reported by the "swap -s" command. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. GBL_SWAP_SPACE_DEVICE_UTIL ---------------------------------- On HP-UX, this is the percentage of device swap space currently in use of the total swap space available. This does not include file system or remote swap space. On HP-UX, note that available swap is only potential swap space. Since swap is allocated in fixed (SWCHUNK) sizes, not all of this space may actually be usable. For example, on a 61 MB disk using 2 MB swap size allocations, 1 MB remains unusable and is considered wasted space. Consequently, 100 percent utilization on a single device is not always obtainable. The wasted swap space, and the remainder of allocated SWCHUNKs that have not been used is what is reported in the hold field of the /usr/sbin/swapinfo command. On HP-UX, when compared to the "swapinfo -mt" command results, this is calculated as: Util = ((USED: dev) sum / (AVAIL: total)) * 100 On SUN, this is the percentage of total system device swap space currently in use. This metric only gives the percentage of swap space used from the available physical swap device space, and does not include the memory that can be used for swap. (On SunOS 5.X, the virtual swap swapfs can allocate swap space from memory.) On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. GBL_SWAP_SPACE_FS_UTIL ---------------------------------- On HP-UX, this is the percentage file system swap space currently in use of the total swap space available. This includes both local and NFS file system swap. Since file system swap is dynamic (it grows in SWCHUNK sizes as needed and is not bounded as device swap is), this number fluctuates as more swap is allocated. When compared to the "swapinfo -mt" command results, this is calculated as: Util = ((USED: fs) sum / (AVAIL: total)) * 100 On Sinix, this is the percentage of swap space in use of the total swap space provided on regular files that were configured for swap. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. GBL_SWAP_SPACE_RESERVED ---------------------------------- The amount of swap space (in MB) reserved for the swapping and paging of programs currently executing. Process pages swapped include data (heap and stack pages), bss (data uninitialized at the beginning of process execution), and the process user area (uarea). Shared memory regions also require the reservation of swap space. Swap space is reserved (by decrementing a counter) when virtual memory for a program is created, but swap is only used when a page or swap to disk is actually done or the page is locked in memory if swapping to memory is enabled. Virtual memory cannot be created if swap space cannot be reserved. On HP-UX, this is the same as (USED: total) as reported by the "swapinfo -mt" command. On SUN, this is the same as used/1024, reported by the "swap -s" command. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. GBL_SWAP_SPACE_RESERVED_UTIL ---------------------------------- This is the percentage of available swap space currently reserved for running processes. Reserved utilization = (amount of swap space reserved / amount of swap space available) * 100 On HP-UX, swap space must be reserved (but not allocated) before virtual memory can be created. If all of available swap is reserved, then no new processes or virtual memory can be created. Swap space locations are actually assigned (used) when a page is actually written to disk. On HP-UX, note that available swap is only potential swap space. Since swap is allocated in fixed (SWCHUNK) sizes, not all of this space may actually be usable. For example, on a 61 MB disk using 2 MB swap size allocations, 1 MB remains unusable and is considered wasted space. Consequently, 100 percent utilization on a single device is not always obtainable. When compared to the "swapinfo -mt" command results, this is calculated as: Util = ((USED: total) / (AVAIL: total)) * 100 On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. GBL_SWAP_SPACE_USED ---------------------------------- The amount of swap space used, in MB. On HP-UX, "Used" indicates written to disk (or locked in memory), rather than reserved. This is the same as (USED: total - reserve) as reported by the "swapinfo -mt" command. On SUN, "Used" indicates amount written to disk (or locked in memory), rather than reserved. Swap space is reserved (by decrementing a counter) when virtual memory for a program is created. This is the same as (bytes allocated)/1024, reported by the "swap -s" command. On Linux, this is same as (Swap: used) as reported by the "free -m" command. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. GBL_SWAP_SPACE_USED_UTIL ---------------------------------- The amount of swap space used, in MB. On HP-UX, "Used" indicates written to disk (or locked in memory), rather than reserved. This is the same as (USED: total - reserve) as reported by the "swapinfo -mt" command. On SUN, "Used" indicates amount written to disk (or locked in memory), rather than reserved. Swap space is reserved (by decrementing a counter) when virtual memory for a program is created. This is the same as (bytes allocated)/1024, reported by the "swap -s" command. On SUN, global swap space is tracked through the operating system. Device swap space is tracked through the devices. For this reason, the amount of swap space used may differ between the global and by-device metrics. Sometimes pages that are marked to be swapped to disk by the operating system are never swapped. The operating system records this as used swap space, but the devices do not, since no physical IOs occur. (Metrics with the prefix "GBL" are global and metrics with the prefix "BYSWP" are by device.) On Linux, this is same as (Swap: used) as reported by the "free -m" command. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. GBL_SWAP_SPACE_UTIL ---------------------------------- The percent of available swap space that was being used by running processes in the interval. On Windows, this is the percentage of virtual memory, which is available to user processes, that is in use at the end of the interval. It is not an average over the entire interval. It reflects the ratio of committed memory to the current commit limit. The limit may be increased by the operating system if the paging file is extended. This is the same as (Committed Bytes / Commit Limit) * 100 when comparing the results to Performance Monitor. On HP-UX, swap space must be reserved (but not allocated) before virtual memory can be created. If all of available swap is reserved, then no new processes or virtual memory can be created. Swap space locations are actually assigned (used) when a page is actually written to disk or locked in memory (pseudo swap in memory). This is the same as (PCT USED: total) as reported by the "swapinfo -mt" command. On Unix systems, this metric is a measure of capacity rather than performance. As this metric nears 100 percent, processes are not able to allocate any more memory and new processes may not be able to run. Very low swap utilization values may indicate that too much area has been allocated to swap, and better use of disk space could be made by reallocating some swap partitions to be user filesystems. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. GBL_SWAP_SPACE_UTIL_CUM ---------------------------------- The average percentage of available swap space currently in use (has memory belonging to processes paged or swapped out on it) over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On HP-UX, note that available swap is only potential swap space. Since swap is allocated in fixed (SWCHUNK) sizes, not all of this space may actually be usable. For example, on a 61 MB disk using 2 MB swap size allocations, 1 MB remains unusable and is considered wasted space. Consequently, 100 percent utilization on a single device is not always obtainable. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. GBL_SWAP_SPACE_UTIL_HIGH ---------------------------------- The highest average percentage of available swap space currently in use (has memory belonging to processes paged or swapped out on it) in any interval over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On HP-UX, note that available swap is only potential swap space. Since swap is allocated in fixed (SWCHUNK) sizes, not all of this space may actually be usable. For example, on a 61 MB disk using 2 MB swap size allocations, 1 MB remains unusable and is considered wasted space. Consequently, 100 percent utilization on a single device is not always obtainable. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. GBL_SYSCALL ---------------------------------- The number of system calls during the interval. High system call rates are normal on busy systems, especially with IO intensive applications. Abnormally high system call rates may indicate problems such as a "hung" terminal that is stuck in a loop generating read system calls. GBL_SYSCALL_RATE ---------------------------------- The average number of system calls per second during the interval. High system call rates are normal on busy systems, especially with IO intensive applications. Abnormally high system call rates may indicate problems such as a "hung" terminal that is stuck in a loop generating read system calls. On HP-UX, system call rates affect the overhead of the midaemon. Due to the system call instrumentation on HP-UX, the fork and vfork system calls are double counted. In the case of fork and vfork, one process starts the system call, but two processes exit. HP-UX lightweight system calls, such as umask, do not show up in the GlancePlus System Calls display, but will get added to the global system call rates. If a process is being traced (debugged) using standard debugging tools (such as adb or xdb), all system calls used by that process will show up in the System Calls display while being traced. On HP-UX, compare this metric to GBL_DISK_LOGL_IO_RATE to see if high system callrates correspond to high disk IO. GBL_CPU_SYSCALL_UTIL shows the CPU utilization due to processing system calls. GBL_SYSCALL_RATE_CUM ---------------------------------- The average number of system calls per second over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. Due to the system call instrumentation on HP-UX, the fork and vfork system calls are double counted. In the case of fork and vfork, one process starts the system call, but two processes exit. HP-UX lightweight system calls, such as umask, do not show up in the GlancePlus System Calls display, but will get added to the global system call rates. If a process is being traced (debugged) using standard debugging tools (such as adb or xdb), all system calls used by that process will show up in the System Calls display while being traced. GBL_SYSCALL_RATE_HIGH ---------------------------------- The highest number of system calls per second during any interval over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. Due to the system call instrumentation on HP-UX, the fork and vfork system calls are double counted. In the case of fork and vfork, one process starts the system call, but two processes exit. HP-UX lightweight system calls, such as umask, do not show up in the GlancePlus System Calls display, but will get added to the global system call rates. If a process is being traced (debugged) using standard debugging tools (such as adb or xdb), all system calls used by that process will show up in the System Calls display while being traced. GBL_SYSTEM_ID ---------------------------------- The network node hostname of the system. This is the same as the output from the "uname -n" command. On Windows, the name obtained from GetComputerName. GBL_SYSTEM_TYPE ---------------------------------- On Unix systems, this is either the model of the system or the instruction set architecture of the system. On Windows, this is the processor architecture of the system. GBL_SYSTEM_UPTIME_HOURS ---------------------------------- The time, in hours, since the last system reboot. GBL_SYSTEM_UPTIME_SECONDS ---------------------------------- The time, in seconds, since the last system reboot. GBL_SYS_QUEUE ---------------------------------- The average number of processes or kernel threads blocked on SYSTM (that is, system resources) during the interval. These resources include data structures from the LVM, VFS, UFS, JFS, and Disk Quota subsystems. "SYSTM" is the "catch-all" wait state for blocks on system resources that are not common enough or long enough to warrant their own stop state. This is calculated as the accumulated time that all processes or kernel threads spent blocked on SYSTM divided by the interval time. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system. No direct comparison is reasonable with the Application WAIT PCT metrics since they represent percentages within the context of a specific application and cannot be summed or compared with global values easily. In addition, the sum of each Application WAIT PCT for all applications will not equal 100% since these values will vary greatly depending on the number of processes or kernel threads in each application. For example, the GBL_DISK_SUBSYSTEM_QUEUE values can be low, while the APP_DISK_SUBSYSTEM_WAIT_PCT values can be high. In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. GBL_SYS_WAIT_PCT ---------------------------------- The percentage of time processes or kernel threads were blocked on SYSTM (that is, system resources) during the interval. These resources include data structures from the LVM, VFS, UFS, JFS, and Disk Quota subsystems. "SYSTM" is the "catch-all" wait state for blocks on system resources that are not common enough or long enough to warrant their own stop state. This is calculated as the accumulated time that all processes or kernel threads spent blocked on SYSTM divided by the accumulated time that all processes or kernel threads were alive during the interval. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system. No direct comparison is reasonable with the Application WAIT PCT metrics since they represent percentages within the context of a specific application and cannot be summed or compared with global values easily. In addition, the sum of each Application WAIT PCT for all applications will not equal 100% since these values will vary greatly depending on the number of processes or kernel threads in each application. For example, the GBL_DISK_SUBSYSTEM_QUEUE values can be low, while the APP_DISK_SUBSYSTEM_WAIT_PCT values can be high. In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. GBL_SYS_WAIT_TIME ---------------------------------- The accumulated time, in seconds, that all processes or kernel threads were blocked on SYSTM (that is, system resources) during the interval. These resources include data structures from the LVM, VFS, UFS, JFS, and Disk Quota subsystems. "SYSTM" is the "catch-all" wait state for blocks on system resources that are not common enough or long enough to warrant their own stop state. GBL_TERM_IO_QUEUE ---------------------------------- The average number of processes or kernel threads blocked on terminal IO (waiting for their terminal IO to complete) during the interval. This is calculated as the accumulated time that all processes or kernel threads spent blocked on TERM (that is, terminal IO) divided by the interval time. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system. No direct comparison is reasonable with the Application WAIT PCT metrics since they represent percentages within the context of a specific application and cannot be summed or compared with global values easily. In addition, the sum of each Application WAIT PCT for all applications will not equal 100% since these values will vary greatly depending on the number of processes or kernel threads in each application. For example, the GBL_DISK_SUBSYSTEM_QUEUE values can be low, while the APP_DISK_SUBSYSTEM_WAIT_PCT values can be high. In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. GBL_TERM_IO_WAIT_PCT ---------------------------------- The percentage of time processes or kernel threads were blocked on terminal IO (waiting for terminal IO to complete) during the interval. This is calculated as the accumulated time that all processes or kernel threads spent blocked on TERM (that is, terminal IO) divided by the accumulated time that all processes or kernel threads were alive during the interval. The Global QUEUE metrics, which are based on block states, represent the average number of process or kernel thread counts, not actual queues. The Global WAIT PCT metrics, which are also based on block states, represent the percentage of all processes or kernel threads that were alive on the system.

In this case, there are many processes on the system, but there are only a very small number of processes in the specific application that is being examined and there is a high percentage of those few processes that are blocked on the disk I/O subsystem. GBL_TERM_IO_WAIT_TIME ---------------------------------- The accumulated time, in seconds, that all processes or kernel threads were blocked on terminal IO (waiting for their terminal IO to complete) during the interval. GBL_TT_OVERFLOW_COUNT ---------------------------------- The number of new transactions that could not be measured because the Measurement Processing Daemon's (midaemon) Measurement Performance Database is full. If this happens, the default Measurement Performance Database size is not large enough to hold all of the registered transactions on this system. This can be remedied by stopping and restarting the midaemon process using the -smdvss option to specify a larger Measurement Performance Database size. The current Measurement Performance Database size can be checked using the midaemon -sizes option.

This metric can be used to help determine which logical volumes are taking more time than usual to process requests. This metric is reported as "na" for LVM. On HP-UX 11i and beyond, data is available from VERITAS Volume Manager (VxVM). LVM (Logical Volume Manager) uses the terminology "volume group" to describe a set of related volumes.

For additional information on VERITAS Volume Manager, see vxintro(1M). LV_CACHE_MISS ---------------------------------- The number of requests that were not satisfied from the Mirror Write Cache (MWC) during the interval.

This metric is reported as "na" for VERITAS Volume Manager. On HP-UX 11i and beyond, data is available from VERITAS Volume Manager (VxVM). LVM (Logical Volume Manager) uses the terminology "volume group" to describe a set of related volumes. VERITAS Volume Manager uses the terminology "disk group" to describe a collection of VM disks. For additional information on VERITAS Volume Manager, see vxintro(1M). LV_CACHE_QUEUE ---------------------------------- The number of requests queued to the Mirror Write Cache (MWC) at the end of the interval. The MWC is only used for volume mirroring and its use degrades performance, as extra work is required during disk writes to maintain the Mirror Write Cache. The MWC is disabled with the lvchange(1M) command ("lvchange -M n..."), which may increase system performance, but slow down recovery in the event of a system failure. This metric is reported as "na" for VERITAS Volume Manager. On HP-UX 11i and beyond, data is available from VERITAS Volume Manager (VxVM). LVM (Logical Volume Manager) uses the terminology "volume group" to describe a set of related volumes. VERITAS Volume Manager uses the terminology "disk group" to describe a collection of VM disks. For additional information on VERITAS Volume Manager, see vxintro(1M). LV_CACHE_SIZE ---------------------------------- The number of entries in this logical volume group's Mirror Write Cache (MWC). The size of this cache is determined by the kernel's logical volume code and is not configurable. The MWC is optional and only used for volume mirroring.

VERITAS Volume Manager uses the terminology "disk group" to describe a collection of VM disks. For additional information on VERITAS Volume Manager, see vxintro(1M). Disk groups in the VERITAS Volume Manager do not have device files. Therefore, "na" is reported for this metric since it is not applicable. LV_DIRNAME ---------------------------------- The path name of this logical volume or volume/disk group. On HP-UX 11i and beyond, data is available from VERITAS Volume Manager (VxVM). LVM (Logical Volume Manager) uses the terminology "volume group" to describe a set of related volumes. VERITAS Volume Manager uses the terminology "disk group" to describe a collection of VM disks. For additional information on VERITAS Volume Manager, see vxintro(1M). For LVM logical volumes, this is the name used as a parameter to the lvdisplay(1M) command. For volume groups, this is the name used as a parameter to the vgdisplay(1M) command. The entry referred to as the "/dev/vgXX/group" entry shows the internal resources used by the LVM software to manage the logical volumes. LV_GROUP_NAME ---------------------------------- On HP-UX, this is the name of this volume/disk group associated with a logical volume.

VERITAS Volume Manager uses the terminology "disk group" to describe a collection of VM disks. For additional information on VERITAS Volume Manager, see vxintro(1M). LV_INTERVAL ---------------------------------- The amount of time in the interval. LV_INTERVAL_CUM ---------------------------------- The amount of time over the cumulative collection time, or since the last configuration change. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. LV_OPEN_LV ---------------------------------- The number of logical volumes currently opened in this volume group (or disk group, if HP-UX). An entry of "na" indicates that there are no logical volumes open in this volume group and there are no active disks in this volume group. On HP-UX, the extra entry (referred to as the "/dev/vgXX/group" entry), shows the internal resources used by the LVM software to manage the logical volumes. On HP-UX 11i and beyond, data is available from VERITAS Volume Manager (VxVM). LVM (Logical Volume Manager) uses the terminology "volume group" to describe a set of related volumes. VERITAS Volume Manager uses the terminology "disk group" to describe a collection of VM disks. For additional information on VERITAS Volume Manager, see vxintro(1M). On SUN, this metric is reported as "na" for logical volumes and metadevices since it is not applicable. LV_READ_BYTE_RATE ---------------------------------- The number of physical KBs per second read from this logical volume during the interval. Note that bytes read from the buffer cache are not included in this calculation. LV_READ_BYTE_RATE_CUM ---------------------------------- The average number of physical KBs per second read from this logical volume over the cumulative collection time, or since the last configuration change. Note that bytes read from the buffer cache are not included in this calculation. On SUN, DiskSuite metadevices are not supported. This metric is reported as "na" for volume groups since it is not applicable. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. LV_READ_RATE ---------------------------------- The number of physical reads per second for this logical volume during the interval. This may not correspond to the physical read rate from a particular disk drive since a logical volume may be composed of many disk drives or it may be a subset of a disk drive. An individual physical read from one logical volume may span multiple individual disk drives. Since this is a physical read rate, there may not be any correspondence to the logical read rate since many small reads are satisfied in the buffer cache, and large logical read requests must be broken up into physical read requests. LV_READ_RATE_CUM ---------------------------------- The average number of physical reads per second for this volume over the cumulative collection time, or since the last configuration change. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last.

LV_WRITE_RATE ---------------------------------- The number of physical writes per second to this logical volume during the interval. This may not correspond to the physical write rate to a particular disk drive since a logical volume may be composed of many disk drives or it may be a subset of a disk drive. Since this is a physical write rate, there may not be any correspondence to the logical write rate since many small writes are combined in the buffer cache, and many large logical writes must be broken up. LV_WRITE_RATE_CUM ---------------------------------- The average number of physical writes per second to this volume over the cumulative collection time, or since the last configuration change. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. PRM_BYVG_GROUP_ENTITLEMENT ---------------------------------- The PRM Disk entitlement for this PRM Group ID entry as defined in the PRM configuration file.

The PRM_BYVG_* metrics report on the total bytes requested/transferred for a specified volume group. The byte counts are the total of various IO requests which result in physical IO activity. These requests may include: - Raw IO directed to a raw logical volume - Delayed Buffer Cache writes - Buffer Cache misses that cause reads - Large IO that bypasses buffer cache - Virtual Memory Paging Activity Since the PRM configuration is dynamic, the collection may be restarted. Two intervals are required before the new values are reported. The first interval after the collection is restarted displays n/a (not available) for all of the counts. PRM_BYVG_REQUEST_CUM ---------------------------------- The number of KBs (or MBs if specified) the PRM group requested be read from or written to the logical volumes in the current volume group over the cumulative collection time, or since the last configuration change.

These requests may include: - Raw IO directed to a raw logical volume - Delayed Buffer Cache writes - Buffer Cache misses that cause reads - Large IO that bypasses buffer cache - Virtual Memory Paging Activity Since the PRM configuration is dynamic, the collection may be restarted. Two intervals are required before the new values are reported. The first interval after the collection is restarted displays n/a (not available) for all of the counts. PRM_BYVG_REQUEST_QUEUE ---------------------------------- The request queue length for the specified volume group. PRM_BYVG_TRANSFER ---------------------------------- The number of KBs (or MBs if specified) the PRM group has read from or written to the logical volumes in the current volume group during the interval. The PRM_BYVG_* metrics report on the total bytes requested/transferred for a specified volume group. The byte counts are the total of various IO requests which result in physical IO activity. These requests may include: - Raw IO directed to a raw logical volume - Delayed Buffer Cache writes - Buffer Cache misses that cause reads - Large IO that bypasses buffer cache - Virtual Memory Paging Activity Since the PRM configuration is dynamic, the collection may be restarted.

PROCSYSCALL_ACTIVE_CUM ---------------------------------- The number of different system calls called by this process during the time it has been enabled for system call profiling. PROCSYSCALL_CALL_COUNT ---------------------------------- The number of system calls made to this function by this process during the interval. PROCSYSCALL_CALL_COUNT_CUM ---------------------------------- The number of system calls made by this process to this function during the time it has been enabled for system call profiling. PROCSYSCALL_CALL_ID ---------------------------------- The ID number of the system call. System calls are sequentially numbered starting with one. PROCSYSCALL_CALL_NAME ---------------------------------- The system call name. PROCSYSCALL_CALL_RATE ---------------------------------- The number of system calls per second made by this process to this function during the last interval. PROCSYSCALL_CALL_RATE_CUM ---------------------------------- The average number of system calls per second made by this process to this function during the time it has been enabled for system call profiling. PROCSYSCALL_INTERVAL ---------------------------------- The amount of time in the interval. PROCSYSCALL_INTERVAL_CUM ---------------------------------- The time, in seconds, system call data has been collected for this process. PROCSYSCALL_TOTAL_TIME ---------------------------------- The elapsed time, in seconds, this process was in this system call. This value maybe greater then the interval time since the system call may have been started before the interval started. PROCSYSCALL_TOTAL_TIME_CUM ---------------------------------- The total elapsed time, in seconds, that this process was in this system call. This value maybe greater than the cumulative interval time since the system call may have been started before data collection. PROC_ACTIVE_PROC THREAD_ACTIVE_THREAD ---------------------------------- The number of active processes (or kernel threads, if HP- UX/Linux Kernel 2.6 and above) in the interval. A process (or kernel thread, if HP-UX/Linux Kernel 2.6 and above) is active if it is alive and consumes CPU time. PROC_APP_ID THREAD_APP_ID ---------------------------------- The ID number of the application to which the process (or kernel thread, if HP-UX/Linux Kernel 2.6 and above) belonged during the interval. Application "other" always has an ID of 1. There can be up to 128 user-defined applications, which are defined in the parm file. PROC_APP_NAME THREAD_APP_NAME ---------------------------------- The application name of a process (or kernel thread, if HP- UX/Linux Kernel 2.6 and above). Processes (or kernel threads, if HP-UX/Linux Kernel 2.6 and above) are assigned into application groups based upon rules in the parm file. If a process does not fit any rules in this file, it is assigned to the application "other." The rules include decisions based upon pathname, user ID, priority, and so forth. As these values change during the life of a process (or kernel thread, if HP-UX/Linux Kernel 2.6 and above), it is re-assigned to another application. This re-evaluation is done every measurement interval. PROC_CACHE_WAIT_PCT THREAD_CACHE_WAIT_PCT ---------------------------------- The percentage of time the process or kernel thread was blocked on CACHE (waiting for the file system buffer cache to be updated) during the interval. Processes or kernel threads doing raw IO to a disk are not included in this measurement. Processes and kernel threads doing buffered IO to disks normally spend more time blocked on CACHE and IO than on DISK. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval. If this metric is reported for a kernel thread, the percentage value is for that single kernel thread. If this metric is reported for a process, the percentage value is calculated with the sum of the wait and alive times of all of its kernel threads. For example, if a process has 2 kernel threads, one sleeping for the entire interval and one waiting on terminal input for the interval, the process wait percent values will be 50% on Sleep and 50% on Terminal. The kernel thread wait values will be 100% on Sleep for the first kernel thread and 100% on Terminal for the second kernel thread. For another example, consider the same process as above, with 2 kernel threads, one of which was created half-way through the interval, and which then slept for the remainder of the interval. The other kernel thread was waiting for terminal input for half the interval, then used the CPU actively for the remainder of the interval. The process wait percent values will be 33% on Sleep and 33% on Terminal (each one third of the total alive time). The kernel thread wait values will be 100% on Sleep for the first kernel thread and 50% on Terminal for the second kernel thread. PROC_CACHE_WAIT_PCT_CUM THREAD_CACHE_WAIT_PCT_CUM ---------------------------------- The average percentage of time the process or kernel thread was blocked on CACHE (waiting for the file system buffer cache to be updated) over the cumulative collection time. Processes or kernel threads doing raw IO to a disk are not included in this measurement. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval. If this metric is reported for a kernel thread, the percentage value is for that single kernel thread. If this metric is reported for a process, the percentage value is calculated with the sum of the wait and alive times of all of its kernel threads. For example, if a process has 2 kernel threads, one sleeping for the entire interval and one waiting on terminal input for the interval, the process wait percent values will be 50% on Sleep and 50% on Terminal. The kernel thread wait values will be 100% on Sleep for the first kernel thread and 100% on Terminal for the second kernel thread. For another example, consider the same process as above, with 2 kernel threads, one of which was created half-way through the interval, and which then slept for the remainder of the interval. The other kernel thread was waiting for terminal input for half the interval, then used the CPU actively for the remainder of the interval. The process wait percent values will be 33% on Sleep and 33% on Terminal (each one third of the total alive time). The kernel thread wait values will be 100% on Sleep for the first kernel thread and 50% on Terminal for the second kernel thread. PROC_CACHE_WAIT_TIME THREAD_CACHE_WAIT_TIME ---------------------------------- The time, in seconds, that the process or kernel thread was blocked on CACHE (waiting for the file system buffer cache to be updated) during the interval. Processes or kernel threads doing raw IO to a disk are not included in this measurement. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. If this metric is reported for a kernel thread, the value is the wait time of that single kernel thread. If this metric is reported for a process, the value is the sum of the wait times of all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. For multi-threaded processes, the wait times can exceed the length of the measurement interval. PROC_CACHE_WAIT_TIME_CUM THREAD_CACHE_WAIT_TIME_CUM ---------------------------------- The time, in seconds, that the process or kernel thread was blocked on CACHE (waiting for the file system buffer cache to be updated) over the cumulative collection time. Processes or kernel threads doing raw IO to a disk are not included in this measurement. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. If this metric is reported for a kernel thread, the value is the wait time of that single kernel thread. If this metric is reported for a process, the value is the sum of the wait times of all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. For multi-threaded processes, the wait times can exceed the length of the measurement interval. PROC_CDFS_WAIT_PCT THREAD_CDFS_WAIT_PCT ---------------------------------- The percentage of time the process or kernel thread was blocked on CDFS (waiting for its Compact Disk file system IO to complete) during the interval. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval. If this metric is reported for a kernel thread, the percentage value is for that single kernel thread. If this metric is reported for a process, the percentage value is calculated with the sum of the wait and alive times of all of its kernel threads. For example, if a process has 2 kernel threads, one sleeping for the entire interval and one waiting on terminal input for the interval, the process wait percent values will be 50% on Sleep and 50% on Terminal. The kernel thread wait values will be 100% on Sleep for the first kernel thread and 100% on Terminal for the second kernel thread. For another example, consider the same process as above, with 2 kernel threads, one of which was created half-way through the interval, and which then slept for the remainder of the interval. The other kernel thread was waiting for terminal input for half the interval, then used the CPU actively for the remainder of the interval.

If this metric is reported for a kernel thread, the percentage value is for that single kernel thread. If this metric is reported for a process, the percentage value is calculated with the sum of the wait and alive times of all of its kernel threads.

On a threaded operating system, such as HP-UX 11.0 and beyond, process usage of a resource is calculated by summing the usage of that resource by its kernel threads. If this metric is reported for a kernel thread, the value is the resource usage by that single kernel thread.

The maximum percentage is 100% times the number of CPUs online. PROC_CPU_SYSCALL_UTIL_CUM THREAD_CPU_SYSCALL_UTIL_CUM ---------------------------------- The average percentage of the total CPU time this process or kernel thread spent executing system calls in system mode over the cumulative collection time.

A process operates in either system mode (also called kernel mode on Unix or privileged mode on Windows) or user mode. When a process requests services from the operating system with a system call, it switches into the machine's privileged protection mode and runs in system mode. On a threaded operating system, such as HP-UX 11.0 and beyond, process usage of a resource is calculated by summing the usage of that resource by its kernel threads.

When a process requests services from the operating system with a system call, it switches into the machine's privileged protection mode and runs in system mode. Unlike the global and application CPU metrics, process CPU is not averaged over the number of processors on systems with multiple CPUs. Single-threaded processes can use only one CPU at a time and never exceed 100% CPU utilization. High system mode CPU utilizations are normal for IO intensive programs. Abnormally high system CPU utilization can indicate that a hardware problem is causing a high interrupt rate. It can also indicate programs that are not using system calls efficiently. A classic "hung shell" shows up with very high system mode CPU because it gets stuck in a loop doing terminal reads (a system call) to a device that never responds.

Also counted are read and write system calls made indirectly through other system calls, including readv, recvfrom, recv, recvmsg, ipcrecvcn, recfrom, writev, send, sento, sendmsg, and ipcsend. "Disk" refers to a physical drive (that is, "spindle"), not a partition on a drive (unless the partition occupies the entire physical disk).

PROC_DISK_LOGL_IO_RATE THREAD_DISK_LOGL_IO_RATE ---------------------------------- The number of logical IOs per second made by (or for) a process or kernel thread during the interval. NFS mounted disks are not included in this list. On many Unix systems, logical disk IOs are measured by counting the read and write system calls that are directed to disk devices. Also counted are read and write system calls made indirectly through other system calls, including readv, recvfrom, recv, recvmsg, ipcrecvcn, recfrom, writev, send, sento, sendmsg, and ipcsend. On many Unix systems, there are several reasons why logical IOs may not correspond with physical IOs. Logical IOs may not always result in a physical disk access, since the data may already reside in memory -- either in the buffer cache, or in virtual memory if the IO is to a memory mapped file. Several logical IOs may all map to the same physical page or block. In these two cases, logical IOs are greater than physical IOs. The reverse can also happen. A single logical write can cause a physical read to fetch the block to be updated from disk, and then cause a physical write to put it back on disk. A single logical IO can require more than one physical page or block, and these can be found on different disks. Mirrored disks further distort the relationship between logical and physical IO, since physical writes are doubled. For processes which run for less than the measurement interval, this metric is normalized over the measurement interval. For example, a process ran for 1 second and did 50 IOs during its life. If the measurement interval is 5 seconds, it is reported as having done 10 IOs per second. If the measurement interval is 60 seconds, it is reported as having done 50/60 or 0.83 IOs per second. "Disk" refers to a physical drive (that is, "spindle"), not a partition on a drive (unless the partition occupies the entire physical disk). On a threaded operating system, such as HP-UX 11.0 and beyond, process usage of a resource is calculated by summing the usage of that resource by its kernel threads. If this metric is reported for a kernel thread, the value is the resource usage by that single kernel thread. If this metric is reported for a process, the value is the sum of the resource usage by all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. PROC_DISK_LOGL_IO_RATE_CUM THREAD_DISK_LOGL_IO_RATE_CUM ---------------------------------- The average number of logical IOs per second made by (or for) a process or kernel thread over the cumulative collection time. Only local disks are counted in this measurement. NFS devices are excluded. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On many Unix systems, logical disk IOs are measured by counting the read and write system calls that are directed to disk devices. Also counted are read and write system calls made indirectly through other system calls, including readv, recvfrom, recv, recvmsg, ipcrecvcn, recfrom, writev, send, sento, sendmsg, and ipcsend. On many Unix systems, there are several reasons why logical IOs may not correspond with physical IOs. Logical IOs may not always result in a physical disk access, since the data may already reside in memory -- either in the buffer cache, or in virtual memory if the IO is to a memory mapped file. Several logical IOs may all map to the same physical page or block. In these two cases, logical IOs are greater than physical IOs. The reverse can also happen. A single logical write can cause a physical read to fetch the block to be updated from disk, and then cause a physical write to put it back on disk. A single logical IO can require more than one physical page or block, and these can be found on different disks. Mirrored disks further distort the relationship between logical and physical IO, since physical writes are doubled. On a threaded operating system, such as HP-UX 11.0 and beyond, process usage of a resource is calculated by summing the usage of that resource by its kernel threads. If this metric is reported for a kernel thread, the value is the resource usage by that single kernel thread.

If this metric is reported for a kernel thread, the value is the resource usage by that single kernel thread. If this metric is reported for a process, the value is the sum of the resource usage by all of its kernel threads.

PROC_DISK_REM_PHYS_WRITE_CUM THREAD_DISK_REM_PHYS_WRITE_CUM ---------------------------------- The number of physical writes made by (or for) a process or kernel thread over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On HP-UX, if an IO cannot be satisfied in a local client machine's memory buffer, a remote physical IO request is generated. This may or may not require a physical disk IO on the remote system.

On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval. If this metric is reported for a kernel thread, the percentage value is for that single kernel thread. If this metric is reported for a process, the percentage value is calculated with the sum of the wait and alive times of all of its kernel threads. For example, if a process has 2 kernel threads, one sleeping for the entire interval and one waiting on terminal input for the interval, the process wait percent values will be 50% on Sleep and 50% on Terminal. The kernel thread wait values will be 100% on Sleep for the first kernel thread and 100% on Terminal for the second kernel thread. For another example, consider the same process as above, with 2 kernel threads, one of which was created half-way through the interval, and which then slept for the remainder of the interval. The other kernel thread was waiting for terminal input for half the interval, then used the CPU actively for the remainder of the interval. The process wait percent values will be 33% on Sleep and 33% on Terminal (each one third of the total alive time). The kernel thread wait values will be 100% on Sleep for the first kernel thread and 50% on Terminal for the second kernel thread.

"Disk" in this instance refers to any locally attached physical disk drives (that is, "spindles") that may hold file systems and/or swap. NFS mounted disks are not included in this list. On HP-UX, since this value is reported by the drivers, multiple physical requests that have been collapsed to a single physical operation (due to driver IO merging) are only counted once.

The time spent waiting in the disk drivers is usually very small. Most of the time, processes doing file system IO are waiting on IO or CACHE. Processes waiting for character (raw) IO to a disk device are usually waiting on IO.

Alive kernel threads and kernel threads that have died during the interval are included in the summation. A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval. If this metric is reported for a kernel thread, the percentage value is for that single kernel thread.

If this metric is reported for a kernel thread, the value is the wait time of that single kernel thread. If this metric is reported for a process, the value is the sum of the wait times of all of its kernel threads.

On a threaded operating system, such as HP-UX 11.0 and beyond, process usage of a resource is calculated by summing the usage of that resource by its kernel threads. If this metric is reported for a kernel thread, the value is the resource usage by that single kernel thread.

If this metric is reported for a process, the value is the sum of the resource usage by all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. PROC_EUID THREAD_EUID ---------------------------------- The Effective User ID of a process(or kernel thread, if HP- UX/Linux Kernel 2.6 and above). On HP-UX, this metric is specific to a process. If this metric is reported for a kernel thread, the value for its associated process is given. PROC_FILE_COUNT ---------------------------------- The number of times this file is opened currently. Terminal devices are often opened more than once by several different processes. PROC_FILE_MODE ---------------------------------- A text string summarizing the type of open mode: rd/wr Opened for input & output read Opened for input only write Opened for output only PROC_FILE_NAME ---------------------------------- The path name or identifying information about the open file descriptor. If the path name string exceeds 40 characters in length, the beginning and the end of the path is shown and the middle of the name is replaced by "...". An attempt is made to obtain the file path name by either searching the current cylinder group to find directory entries that point to the currently opened inode, or by searching the kernel name cache. Since looking up file path names would require high disk overhead, some names may not be resolved. If the path name can not be resolved, a string is returned indicating the type and inode number of the file. For HP-UX 11.0 releases, the path name information of a file descriptor may correspond to streams device files, such as /dev/tcp and /dev/udp, which are not explicitly opened by the process. These files are opened by networking functions called by the process to access remote systems. For the string format including an inode number, you may use the ncheck(1M) program to display the file path name relative to the mount point. Sometimes files may be deleted before they are closed. In these cases, the process file table may still have the inode even though the file is not actually present and as a result, ncheck will fail. In the following example, note that the file system name has been included to avoid the overhead of ncheck searching all of the file systems for the inode number. If the following file information was displayed: Note that the following examples would all appear on one line. and then from that display, the following ncheck command was entered: ncheck -i 702 -F vxfs /dev/vg00/lvol8 An output like the following would be generated: /dev/vg00/lvol8: 702 /adm/cron/log Since in this example /var is mounted on lvol8 of vg00, the full path name would be /var/adm/cron/log. The string shown representing inode information when the path is not available is as follows: where: The file type can be one of: blk - Block device chr - Character device dir - Directory file fifo - FIFO lnk - Soft file link reg - Regular file sock - Socket emptydir - Mknod created directory - no files ukn - Unknown vtype The file domain can be one of: ufs - Unix file system nfs - NFS vxfs - Veritas file system cdfs - CDROM file system nfs_spec - NFS special device file nfs_bdev - NFS device file - block mode access nfs_fifo - FIFO file access over NFS dev_vn - Generic vnode - temp type used by kernel dummy - OSF's file on file mount file system pipe - Pipe ukn - Unknown vfs type The filesys is the file system mount point. The volume field indicates the logical volume, if applicable. For HP-UX 10.30 and earlier releases, if the file descriptor represents an open socket, the output format will contain the domain and protocol, followed by the IP address. For HP-UX 11.0 and later, if the file descriptor represents a Unix address family socket which is used for IPC on the local host, its path name will be resolved if possible. For example: unix /tmp/.AgentSockets/A If the local socket pathname cannot be resolved, the socket address will be shown, for example: unix -> 0x0339a200 For HP-UX 11.0 and later, if the file descriptor is a socket for internetwork communications (for example, udp or tcp), the socket address, domain, and protocol will be displayed respectively. The bound IP address and port number will also be displayed when available. For example: PROC_FILE_NUMBER ---------------------------------- The file number of the current open file. PROC_FILE_OFFSET ---------------------------------- The decimal value of the next access position of the current file at the end of the interval. If the open file is a tty, this is the total number of bytes sent and received since the file was first opened. PROC_FILE_OPEN ---------------------------------- Number of files the current process has remaining open as of the end of the interval. PROC_FILE_TYPE ---------------------------------- A text string describing the type of the current file. This is one of: block Block special device chr Character device dir Directory fifo FIFO file Simple file link Symbolic File link network Network channel device other An unknown file type pipe Named pipe (FIFO) reg Regular file socket Socket streams Streams PROC_FORCED_CSWITCH THREAD_FORCED_CSWITCH ---------------------------------- The number of times that the process (or kernel thread, if HP-UX) was preempted by an external event and another process (or kernel thread, if HP-UX) was allowed to execute during the interval. Examples of reasons for a forced switch include expiration of a time slice or returning from a system call with a higher priority process (or kernel thread, if HP-UX) ready to run. On a threaded operating system, such as HP-UX 11.0 and beyond, process usage of a resource is calculated by summing the usage of that resource by its kernel threads. If this metric is reported for a kernel thread, the value is the resource usage by that single kernel thread. If this metric is reported for a process, the value is the sum of the resource usage by all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. PROC_FORCED_CSWITCH_CUM THREAD_FORCED_CSWITCH_CUM ---------------------------------- The number of times the process (or kernel thread, if HP-UX) was preempted by an external event and another process (or kernel thread, if HP-UX) was allowed to execute over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. Examples of reasons for a forced switch include expiration of a time slice or returning from a system call with a higher priority process (or kernel thread, if HP-UX) ready to run. On a threaded operating system, such as HP-UX 11.0 and beyond, process usage of a resource is calculated by summing the usage of that resource by its kernel threads. If this metric is reported for a kernel thread, the value is the resource usage by that single kernel thread. If this metric is reported for a process, the value is the sum of the resource usage by all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. PROC_FORK THREAD_FORK ---------------------------------- The total number of fork and vfork system calls executed by this process during the interval. On HP-UX, this metric is specific to a process. If this metric is reported for a kernel thread, the value for its associated process is given. PROC_FORK_CUM THREAD_FORK_CUM ---------------------------------- The number of fork or vfork system calls made by a process over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On HP-UX, this metric is specific to a process. If this metric is reported for a kernel thread, the value for its associated process is given. PROC_GRAPHICS_WAIT_PCT THREAD_GRAPHICS_WAIT_PCT ---------------------------------- The percentage of time the process or kernel thread was blocked on graphics (waiting for graphics operations to complete) during the interval. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval. If this metric is reported for a kernel thread, the percentage value is for that single kernel thread. If this metric is reported for a process, the percentage value is calculated with the sum of the wait and alive times of all of its kernel threads. For example, if a process has 2 kernel threads, one sleeping for the entire interval and one waiting on terminal input for the interval, the process wait percent values will be 50% on Sleep and 50% on Terminal. The kernel thread wait values will be 100% on Sleep for the first kernel thread and 100% on Terminal for the second kernel thread. For another example, consider the same process as above, with 2 kernel threads, one of which was created half-way through the interval, and which then slept for the remainder of the interval. The other kernel thread was waiting for terminal input for half the interval, then used the CPU actively for the remainder of the interval. The process wait percent values will be 33% on Sleep and 33% on Terminal (each one third of the total alive time). The kernel thread wait values will be 100% on Sleep for the first kernel thread and 50% on Terminal for the second kernel thread. PROC_GRAPHICS_WAIT_PCT_CUM THREAD_GRAPHICS_WAIT_PCT_CUM ---------------------------------- The percentage of time the process or kernel thread was blocked on graphics (waiting for graphics operations to complete) over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last.

If this metric is reported for a kernel thread, the percentage value is for that single kernel thread. If this metric is reported for a process, the percentage value is calculated with the sum of the wait and alive times of all of its kernel threads. For example, if a process has 2 kernel threads, one sleeping for the entire interval and one waiting on terminal input for the interval, the process wait percent values will be 50% on Sleep and 50% on Terminal. The kernel thread wait values will be 100% on Sleep for the first kernel thread and 100% on Terminal for the second kernel thread. For another example, consider the same process as above, with 2 kernel threads, one of which was created half-way through the interval, and which then slept for the remainder of the interval. The other kernel thread was waiting for terminal input for half the interval, then used the CPU actively for the remainder of the interval. The process wait percent values will be 33% on Sleep and 33% on Terminal (each one third of the total alive time). The kernel thread wait values will be 100% on Sleep for the first kernel thread and 50% on Terminal for the second kernel thread. PROC_GRAPHICS_WAIT_TIME THREAD_GRAPHICS_WAIT_TIME ---------------------------------- The time, in seconds, that the process or kernel thread was blocked on graphics (waiting for their graphics operations to complete) during the interval. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. If this metric is reported for a kernel thread, the value is the wait time of that single kernel thread. If this metric is reported for a process, the value is the sum of the wait times of all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. For multi-threaded processes, the wait times can exceed the length of the measurement interval. PROC_GRAPHICS_WAIT_TIME_CUM THREAD_GRAPHICS_WAIT_TIME_CUM ---------------------------------- The time, in seconds, that the process or kernel thread was blocked on graphics (waiting for their graphics operations to complete) over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. If this metric is reported for a kernel thread, the value is the wait time of that single kernel thread. If this metric is reported for a process, the value is the sum of the wait times of all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. For multi-threaded processes, the wait times can exceed the length of the measurement interval. PROC_GROUP_ID THREAD_GROUP_ID ---------------------------------- On most systems, this is the real group ID number of the process (or kernel thread, if HP-UX/Linux Kernel 2.6 and above). On AIX, this is the effective group ID number of the process. On HP-UX, this is the effective group ID number of the process if not in setgid mode. On HP-UX, this metric is specific to a process. If this metric is reported for a kernel thread, the value for its associated process is given. PROC_GROUP_NAME THREAD_GROUP_NAME ---------------------------------- The group name (from /etc/group) of a process(or kernel thread, if HP-UX/Linux Kernel 2.6 and above). The group identifier is obtained from searching the /etc/passwd file using the user ID (uid) as a key. Therefore, if more than one account is listed in /etc/passwd with the same user ID (uid) field, the first one is used. If no entry can be found for the user ID in /etc/passwd, the group name is the uid number. If no matching entry in /etc/group can be found, the group ID is returned as the group name. On HP-UX, this metric is specific to a process. If this metric is reported for a kernel thread, the value for its associated process is given. PROC_INODE_WAIT_PCT THREAD_INODE_WAIT_PCT ---------------------------------- The percentage of time the process or kernel thread was blocked on INODE (waiting for an inode to be updated or to become available) during the interval. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval. If this metric is reported for a kernel thread, the percentage value is for that single kernel thread. If this metric is reported for a process, the percentage value is calculated with the sum of the wait and alive times of all of its kernel threads. For example, if a process has 2 kernel threads, one sleeping for the entire interval and one waiting on terminal input for the interval, the process wait percent values will be 50% on Sleep and 50% on Terminal. The kernel thread wait values will be 100% on Sleep for the first kernel thread and 100% on Terminal for the second kernel thread. For another example, consider the same process as above, with 2 kernel threads, one of which was created half-way through the interval, and which then slept for the remainder of the interval. The other kernel thread was waiting for terminal input for half the interval, then used the CPU actively for the remainder of the interval. The process wait percent values will be 33% on Sleep and 33% on Terminal (each one third of the total alive time). The kernel thread wait values will be 100% on Sleep for the first kernel thread and 50% on Terminal for the second kernel thread. PROC_INODE_WAIT_PCT_CUM THREAD_INODE_WAIT_PCT_CUM ---------------------------------- The average percentage of time the process or kernel thread was blocked on INODE (waiting for an inode to be updated or to become available) over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval. If this metric is reported for a kernel thread, the percentage value is for that single kernel thread. If this metric is reported for a process, the percentage value is calculated with the sum of the wait and alive times of all of its kernel threads. For example, if a process has 2 kernel threads, one sleeping for the entire interval and one waiting on terminal input for the interval, the process wait percent values will be 50% on Sleep and 50% on Terminal.

The kernel thread wait values will be 100% on Sleep for the first kernel thread and 50% on Terminal for the second kernel thread. PROC_INODE_WAIT_TIME THREAD_INODE_WAIT_TIME ---------------------------------- The time, in seconds, that the process or kernel thread was blocked on INODE (waiting for an inode to be updated or to become available) during the interval. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. If this metric is reported for a kernel thread, the value is the wait time of that single kernel thread. If this metric is reported for a process, the value is the sum of the wait times of all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. For multi-threaded processes, the wait times can exceed the length of the measurement interval. PROC_INODE_WAIT_TIME_CUM THREAD_INODE_WAIT_TIME_CUM ---------------------------------- The time, in seconds, that the process or kernel thread was blocked on INODE (waiting for an inode to be updated or to become available) over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. If this metric is reported for a kernel thread, the value is the wait time of that single kernel thread. If this metric is reported for a process, the value is the sum of the wait times of all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. For multi-threaded processes, the wait times can exceed the length of the measurement interval. PROC_INTERRUPTS THREAD_INTERRUPTS ---------------------------------- The number of interrupts during the interval. PROC_INTERRUPTS_CUM THREAD_INTERRUPTS_CUM ---------------------------------- The number of interrupts over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. PROC_INTERVAL THREAD_INTERVAL ---------------------------------- The amount of time in the interval. This is the same value for all processes (and kernel threads, if HP-UX/Linux Kernel 2.6 and above), regardless of whether they were alive for the entire interval. Note, calculations such as utilizations or rates are calculated using this standardized process interval (PROC_INTERVAL), rather than the actual alive time during the interval (PROC_INTERVAL_ALIVE). Thus, if a process was only alive for 1 second and used the CPU during its entire life (1 second), but the process sample interval was 5 seconds, it would be reported as using 1/5 or 20% CPU utilization, rather than 100% CPU utilization. PROC_INTERVAL_ALIVE THREAD_INTERVAL_ALIVE ---------------------------------- The number of seconds that the process (or kernel thread, if HP-UX/Linux Kernel 2.6 and above) was alive during the interval. This may be less than the time of the interval if the process (or kernel thread, if HP-UX/Linux Kernel 2.6 and above) was new or died during the interval. PROC_INTERVAL_CUM THREAD_INTERVAL_CUM ---------------------------------- The amount of time over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On SUN, AIX, and OSF1, this differs from PROC_RUN_TIME in that PROC_RUN_TIME may not include all of the first and last sample interval times and PROC_INTERVAL_CUM does. PROC_IOCTL THREAD_IOCTL ---------------------------------- The number of file ioctls made by the process during the interval. ioctls that result in data read from or written to a device are not counted. These are counted under disk and non-disk read and writes. This metric is no longer collected on HP-UX 11.0 and beyond. PROC_IOCTL_CUM THREAD_IOCTL_CUM ---------------------------------- The number of file ioctls made by the process over the cumulative collection time. ioctls that result in data read from or written to a device are not counted. These are counted under disk and non-disk reads and writes. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. This metric is no longer collected on HP-UX 11.0 and beyond. PROC_IO_BYTE THREAD_IO_BYTE ---------------------------------- On HP-UX, this is the total number of physical IO KBs (unless otherwise specified) that was used by this process or kernel thread, either directly or indirectly, during the interval. On all other systems, this is the total number of physical IO KBs (unless otherwise specified) that was used by this process during the interval. IOs include disk, terminal, tape and network IO. On HP-UX, indirect IOs include paging and deactivation/reactivation activity done by the kernel on behalf of the process or kernel thread. Direct IOs include disk, terminal, tape, and network IO, but exclude all NFS traffic. On a threaded operating system, such as HP-UX 11.0 and beyond, process usage of a resource is calculated by summing the usage of that resource by its kernel threads. If this metric is reported for a kernel thread, the value is the resource usage by that single kernel thread. If this metric is reported for a process, the value is the sum of the resource usage by all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. On SUN, counts in the MB ranges in general can be attributed to disk accesses and counts in the KB ranges can be attributed to terminal IO. This is useful when looking for processes with heavy disk IO activity. This may vary depending on the sample interval length. PROC_IO_BYTE_CUM THREAD_IO_BYTE_CUM ---------------------------------- On HP-UX, this is the total number of physical IO KBs (unless otherwise specified) that was used by this process or kernel thread, either directly or indirectly, over the cumulative collection time. On all other systems, this is the total number of physical IO KBs (unless otherwise specified) that was used by this process over the cumulative collection time. IOs include disk, terminal, tape and network IO. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last.

If this metric is reported for a process, the value is the sum of the resource usage by all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. PROC_IO_BYTE_RATE THREAD_IO_BYTE_RATE ---------------------------------- On HP-UX, this is the number of physical IO KBs per second that was used by this process or kernel thread, either directly or indirectly, during the interval. On all other systems, this is the number of physical IO KBs per second that was used by this process during the interval. IOs include disk, terminal, tape and network IO. On HP-UX, indirect IOs include paging and deactivation/reactivation activity done by the kernel on behalf of the process or kernel thread. Direct IOs include disk, terminal, tape, and network IO, but exclude all NFS traffic. On a threaded operating system, such as HP-UX 11.0 and beyond, process usage of a resource is calculated by summing the usage of that resource by its kernel threads.

On SUN, counts in the MB ranges in general can be attributed to disk accesses and counts in the KB ranges can be attributed to terminal IO. This is useful when looking for processes with heavy disk IO activity. This may vary depending on the sample interval length. Certain types of disk IOs are not counted by AIX at the process level, so they are excluded from this metric. PROC_IO_BYTE_RATE_CUM THREAD_IO_BYTE_RATE_CUM ---------------------------------- On HP-UX, this is the average number of physical IO KBs per second that was used by this process or kernel thread, either directly or indirectly, over the cumulative collection time. On all other systems, this is the average number of physical IO KBs per second that was used by this process over the cumulative collection time. IOs include disk, terminal, tape and network IO.

This is useful when looking for processes with heavy disk IO activity. This may vary depending on the sample interval length. PROC_IPC_SUBSYSTEM_WAIT_PCT THREAD_IPC_SUBSYSTEM_WAIT_PCT ---------------------------------- The percentage of time the process or kernel thread was blocked on the InterProcess Communication (IPC) subsystems (waiting for its interprocess communication activity to complete) during the interval. This is the sum of processes or kernel threads in the IPC, MSG, SEM, PIPE, SOCKT (that is, sockets) and STRMS (that is, streams IO) wait states. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval. If this metric is reported for a kernel thread, the percentage value is for that single kernel thread. If this metric is reported for a process, the percentage value is calculated with the sum of the wait and alive times of all of its kernel threads. For example, if a process has 2 kernel threads, one sleeping for the entire interval and one waiting on terminal input for the interval, the process wait percent values will be 50% on Sleep and 50% on Terminal. The kernel thread wait values will be 100% on Sleep for the first kernel thread and 100% on Terminal for the second kernel thread. For another example, consider the same process as above, with 2 kernel threads, one of which was created half-way through the interval, and which then slept for the remainder of the interval.

PROC_IPC_SUBSYSTEM_WAIT_PCT_CUM THREAD_IPC_SUBSYSTEM_WAIT_PCT_CUM ---------------------------------- The percentage of time process or kernel thread was blocked on the InterProcess Communication (IPC) subsystems (waiting for its interprocess communication activity to complete) over the cumulative collection time. This is the sum of processes or kernel threads in the IPC, MSG, SEM, PIPE, SOCKT (that is, sockets) and STRMS (that is, streams IO) wait states. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last.

This is the sum of processes or kernel threads in the IPC, MSG, SEM, PIPE, SOCKT (that is, sockets) and STRMS (that is, streams IO) wait states. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. If this metric is reported for a kernel thread, the value is the wait time of that single kernel thread. If this metric is reported for a process, the value is the sum of the wait times of all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. For multi-threaded processes, the wait times can exceed the length of the measurement interval. PROC_IPC_WAIT_PCT THREAD_IPC_WAIT_PCT ---------------------------------- The percentage of time the process or kernel thread was blocked on IPC (waiting for interprocess communication calls to complete) during the interval. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval. If this metric is reported for a kernel thread, the percentage value is for that single kernel thread. If this metric is reported for a process, the percentage value is calculated with the sum of the wait and alive times of all of its kernel threads. For example, if a process has 2 kernel threads, one sleeping for the entire interval and one waiting on terminal input for the interval, the process wait percent values will be 50% on Sleep and 50% on Terminal. The kernel thread wait values will be 100% on Sleep for the first kernel thread and 100% on Terminal for the second kernel thread. For another example, consider the same process as above, with 2 kernel threads, one of which was created half-way through the interval, and which then slept for the remainder of the interval. The other kernel thread was waiting for terminal input for half the interval, then used the CPU actively for the remainder of the interval. The process wait percent values will be 33% on Sleep and 33% on Terminal (each one third of the total alive time). The kernel thread wait values will be 100% on Sleep for the first kernel thread and 50% on Terminal for the second kernel thread. PROC_IPC_WAIT_PCT_CUM THREAD_IPC_WAIT_PCT_CUM ---------------------------------- The average percentage of time the process or kernel thread was blocked on IPC waiting for interprocess communication calls to complete over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval. If this metric is reported for a kernel thread, the percentage value is for that single kernel thread. If this metric is reported for a process, the percentage value is calculated with the sum of the wait and alive times of all of its kernel threads. For example, if a process has 2 kernel threads, one sleeping for the entire interval and one waiting on terminal input for the interval, the process wait percent values will be 50% on Sleep and 50% on Terminal. The kernel thread wait values will be 100% on Sleep for the first kernel thread and 100% on Terminal for the second kernel thread.

The process wait percent values will be 33% on Sleep and 33% on Terminal (each one third of the total alive time). The kernel thread wait values will be 100% on Sleep for the first kernel thread and 50% on Terminal for the second kernel thread.

For multi-threaded processes, the wait times can exceed the length of the measurement interval. PROC_JOBCTL_WAIT_PCT THREAD_JOBCTL_WAIT_PCT ---------------------------------- The percentage of time during the interval the process or kernel thread was blocked on job control (having been stopped with the job control facilities) during the interval. Job control waits include waiting at a debug breakpoint, as well as being blocked attempting to write (from background) to a terminal which has the "stty tostop" option set. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval. If this metric is reported for a kernel thread, the percentage value is for that single kernel thread. If this metric is reported for a process, the percentage value is calculated with the sum of the wait and alive times of all of its kernel threads.

PROC_LAN_WAIT_PCT THREAD_LAN_WAIT_PCT ---------------------------------- The percentage of time the process or kernel thread was blocked on LAN (waiting for IO over the LAN to complete) during the interval. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval. If this metric is reported for a kernel thread, the percentage value is for that single kernel thread.

PROC_LAN_WAIT_PCT_CUM THREAD_LAN_WAIT_PCT_CUM ---------------------------------- The average percentage of time the process or kernel thread was blocked on LAN (waiting for IO over the LAN to complete) over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last.

PROC_LAN_WAIT_TIME THREAD_LAN_WAIT_TIME ---------------------------------- The time, in seconds, that the process or kernel thread was blocked on LAN (waiting for IO over the LAN to complete) during the interval. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads.

PROC_LAN_WAIT_TIME_CUM THREAD_LAN_WAIT_TIME_CUM ---------------------------------- The time, in seconds, that the process or kernel thread was blocked on LAN (waiting for IO over the LAN to complete) over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last.

Alive kernel threads and kernel threads that have died during the interval are included in the summation. For multi-threaded processes, the wait times can exceed the length of the measurement interval. PROC_MAJOR_FAULT THREAD_MAJOR_FAULT ---------------------------------- Number of major page faults for this process (or kernel thread, if HP-UX/Linux Kernel 2.6 and above) during the interval. On HP-UX, major page faults and minor page faults are a subset of vfaults (virtual faults). Stack and heap accesses can cause vfaults, but do not result in a disk page having to be loaded into memory. PROC_MAJOR_FAULT_CUM THREAD_MAJOR_FAULT_CUM ---------------------------------- Number of major page faults for this process (or kernel thread, if HP-UX/Linux Kernel 2.6 and above) over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On HP-UX, major page faults and minor page faults are a subset of vfaults (virtual faults). Stack and heap accesses can cause vfaults, but do not result in a disk page having to be loaded into memory. PROC_MEM_PRIVATE_RES THREAD_MEM_PRIVATE_RES ---------------------------------- The size (in KB) of resident memory of private regions only, such as data and stack, currently consumed by this process. On HP-UX, this metric is initialized only when the menu option "Process Memory Region" is activated for the process. A value of "na" is displayed otherwise. A value of "na" is displayed when this information is unobtainable. On HP-UX, this metric is specific to a process. If this metric is reported for a kernel thread, the value for its associated process is given. PROC_MEM_RES THREAD_MEM_RES ---------------------------------- The size (in KB) of resident memory allocated for the process(or kernel thread, if HP-UX/Linux Kernel 2.6 and above). On HP-UX, the calculation of this metric differs depending on whether this process has used any CPU time since the midaemon process was started. This metric is less accurate and does not include shared memory regions in its calculation when the process has been idle since the midaemon was started. On HP-UX, for processes that use CPU time subsequent to midaemon startup, the resident memory is calculated as RSS = sum of private region pages + (sum of shared region pages / number of references) The number of references is a count of the number of attachments to the memory region. Attachments, for shared regions, may come from several processes sharing the same memory, a single process with multiple attachments, or combinations of these. This value is only updated when a process uses CPU. Thus, under memory pressure, this value may be higher than the actual amount of resident memory for processes which are idle because their memory pages may no longer be resident or the reference count for shared segments may have changed. On HP-UX, this metric is specific to a process. If this metric is reported for a kernel thread, the value for its associated process is given. A value of "na" is displayed when this information is unobtainable. This information may not be obtainable for some system (kernel) processes. It may also not be available for processes. On AIX, this is the same as the RSS value shown by "ps v". On Windows, this is the number of KBs in the working set of this process. The working set includes the memory pages touched recently by the threads of the process. If free memory in the system is above a threshold, then pages are left in the working set even if they are not in use. When free memory falls below a threshold, pages are trimmed from the working set, but not necessarily paged out to disk from memory. If those pages are subsequently referenced, they will be page faulted back into the working set. Therefore, the working set is a general indicator of the memory resident set size of this process, but it will vary depending on the overall status of memory on the system. Note that the size of the working set is often larger than the amount of pagefile space consumed (PROC_MEM_VIRT). PROC_MEM_RES_HIGH THREAD_MEM_RES_HIGH ---------------------------------- The largest value of resident memory (in KB) during its lifetime. See the description for PROC_MEM_RES for details about how resident memory is determined. A value of "na" is displayed when this information is unobtainable. On HP-UX, this metric is specific to a process. If this metric is reported for a kernel thread, the value for its associated process is given. PROC_MEM_SHARED_RES THREAD_MEM_SHARED_RES ---------------------------------- The size (in KB) of resident memory of shared regions only, such as shared text, shared memory, and shared libraries. On HP-UX, this value is not affected by the reference count. A value of "na" is displayed when this information is unobtainable. On HP-UX, this metric is specific to a process. If this metric is reported for a kernel thread, the value for its associated process is given. PROC_MEM_VFAULT_COUNT THREAD_MEM_VFAULT_COUNT ---------------------------------- The number of times the CPU handled vfaults on behalf of this process or kernel thread during the interval. On HP-UX, major page faults and minor page faults are a subset of vfaults (virtual faults). Stack and heap accesses can cause vfaults, but do not result in a disk page having to be loaded into memory. On HP-UX, all exceptions (including faults) cause traps. These include pfaults (protection faults), vfaults (virtual faults), time slice expiration (rescheduling), zero divide, illegal or privileged instructions, single-stepping, breakpoints, and so on. The kernel trap handler code will switch trap counters for vfaults and pfaults to fault counters when appropriate. As such, the trap count excludes vfaults and pfaults. On a threaded operating system, such as HP-UX 11.0 and beyond, process usage of a resource is calculated by summing the usage of that resource by its kernel threads. If this metric is reported for a kernel thread, the value is the resource usage by that single kernel thread. If this metric is reported for a process, the value is the sum of the resource usage by all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. PROC_MEM_VFAULT_COUNT_CUM THREAD_MEM_VFAULT_COUNT_CUM ---------------------------------- The number of times the CPU handled vfaults on behalf of this process or kernel thread over the cumulative collection time. On HP-UX, major page faults and minor page faults are a subset of vfaults (virtual faults). Stack and heap accesses can cause vfaults, but do not result in a disk page having to be loaded into memory. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On HP-UX, all exceptions (including faults) cause traps. These include pfaults (protection faults), vfaults (virtual faults), time slice expiration (rescheduling), zero divide, illegal or privileged instructions, single-stepping, breakpoints, and so on. The kernel trap handler code will switch trap counters for vfaults and pfaults to fault counters when appropriate. As such, the trap count excludes vfaults and pfaults. On a threaded operating system, such as HP-UX 11.0 and beyond, process usage of a resource is calculated by summing the usage of that resource by its kernel threads. If this metric is reported for a kernel thread, the value is the resource usage by that single kernel thread. If this metric is reported for a process, the value is the sum of the resource usage by all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. PROC_MEM_VIRT THREAD_MEM_VIRT ---------------------------------- The size (in KB) of virtual memory allocated for the process(or kernel thread, if HP-UX/Linux Kernel 2.6 and above). On HP-UX, this consists of the sum of the virtual set size of all private memory regions used by this process, plus this process' share of memory regions which are shared by multiple processes. For processes that use CPU time, the value is divided by the reference count for those regions which are shared. On HP-UX, this metric is less accurate and does not reflect the reference count for shared regions for processes that were started prior to the midaemon process and have not used any CPU time since the midaemon was started. On HP-UX, this metric is specific to a process. If this metric is reported for a kernel thread, the value for its associated process is given. On all other Unix systems, this consists of private text, private data, private stack and shared memory. The reference count for shared memory is not taken into account, so the value of this metric represents the total virtual size of all regions regardless of the number of processes sharing access. Note also that lazy swap algorithms, sparse address space malloc calls, and memory-mapped file access can result in large VSS values. On systems that provide Glance memory regions detail reports, the drilldown detail per memory region is useful to understand the nature of memory allocations for the process. A value of "na" is displayed when this information is unobtainable. This information may not be obtainable for some system (kernel) processes. It may also not be available for processes. On Windows, this is the number of KBs the process has used in the paging file(s). Paging files are used to store pages of memory used by the process, such as local data, that are not contained in other files. Examples of memory pages which are contained in other files include pages storing a program's .EXE and .DLL files. These would not be kept in pagefile space. Thus, often programs will have a memory working set size (PROC_MEM_RES) larger than the size of its pagefile space. On Linux this value is rounded to PAGESIZE. PROC_MEM_WAIT_PCT THREAD_MEM_WAIT_PCT ---------------------------------- The percentage of time the process or kernel thread was blocked on memory (waiting for memory resources to become available) during the interval. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval. If this metric is reported for a kernel thread, the percentage value is for that single kernel thread. If this metric is reported for a process, the percentage value is calculated with the sum of the wait and alive times of all of its kernel threads. For example, if a process has 2 kernel threads, one sleeping for the entire interval and one waiting on terminal input for the interval, the process wait percent values will be 50% on Sleep and 50% on Terminal. The kernel thread wait values will be 100% on Sleep for the first kernel thread and 100% on Terminal for the second kernel thread. For another example, consider the same process as above, with 2 kernel threads, one of which was created half-way through the interval, and which then slept for the remainder of the interval. The other kernel thread was waiting for terminal input for half the interval, then used the CPU actively for the remainder of the interval. The process wait percent values will be 33% on Sleep and 33% on Terminal (each one third of the total alive time). The kernel thread wait values will be 100% on Sleep for the first kernel thread and 50% on Terminal for the second kernel thread. PROC_MEM_WAIT_PCT_CUM THREAD_MEM_WAIT_PCT_CUM ---------------------------------- The average percentage of time the process or kernel thread was blocked on memory (waiting for memory resources to become available) over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval. If this metric is reported for a kernel thread, the percentage value is for that single kernel thread. If this metric is reported for a process, the percentage value is calculated with the sum of the wait and alive times of all of its kernel threads. For example, if a process has 2 kernel threads, one sleeping for the entire interval and one waiting on terminal input for the interval, the process wait percent values will be 50% on Sleep and 50% on Terminal. The kernel thread wait values will be 100% on Sleep for the first kernel thread and 100% on Terminal for the second kernel thread. For another example, consider the same process as above, with 2 kernel threads, one of which was created half-way through the interval, and which then slept for the remainder of the interval. The other kernel thread was waiting for terminal input for half the interval, then used the CPU actively for the remainder of the interval. The process wait percent values will be 33% on Sleep and 33% on Terminal (each one third of the total alive time). The kernel thread wait values will be 100% on Sleep for the first kernel thread and 50% on Terminal for the second kernel thread. PROC_MEM_WAIT_TIME THREAD_MEM_WAIT_TIME ---------------------------------- The time, in seconds, that the process or kernel thread was blocked on VM (waiting for virtual memory resources to become available) during the interval. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. If this metric is reported for a kernel thread, the value is the wait time of that single kernel thread. If this metric is reported for a process, the value is the sum of the wait times of all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. For multi-threaded processes, the wait times can exceed the length of the measurement interval. PROC_MEM_WAIT_TIME_CUM THREAD_MEM_WAIT_TIME_CUM ---------------------------------- The time, in seconds, that the process or kernel thread was blocked on VM (waiting for virtual memory resources to become available) over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. If this metric is reported for a kernel thread, the value is the wait time of that single kernel thread. If this metric is reported for a process, the value is the sum of the wait times of all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation.

On HP-UX, major page faults and minor page faults are a subset of vfaults (virtual faults). Stack and heap accesses can cause vfaults, but do not result in a disk page having to be loaded into memory. PROC_MINOR_FAULT_CUM THREAD_MINOR_FAULT_CUM ---------------------------------- Number of minor page faults for this process (or kernel thread, if HP-UX/Linux Kernel 2.6 and above) over the cumulative collection time.

This does not include SYSV messages (msgrcv). PROC_MSG_RECEIVED_CUM THREAD_MSG_RECEIVED_CUM ---------------------------------- The total number of socket messages received by a process or kernel thread over the cumulative collection time. This does not include SYSV messages (msgrcv).

A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval. If this metric is reported for a kernel thread, the percentage value is for that single kernel thread. If this metric is reported for a process, the percentage value is calculated with the sum of the wait and alive times of all of its kernel threads. For example, if a process has 2 kernel threads, one sleeping for the entire interval and one waiting on terminal input for the interval, the process wait percent values will be 50% on Sleep and 50% on Terminal. The kernel thread wait values will be 100% on Sleep for the first kernel thread and 100% on Terminal for the second kernel thread. For another example, consider the same process as above, with 2 kernel threads, one of which was created half-way through the interval, and which then slept for the remainder of the interval. The other kernel thread was waiting for terminal input for half the interval, then used the CPU actively for the remainder of the interval. The process wait percent values will be 33% on Sleep and 33% on Terminal (each one third of the total alive time).

PROC_NICE_PRI THREAD_NICE_PRI ---------------------------------- The nice priority for the process (or kernel thread, if HP- UX/Linux Kernel 2.6 and above) when it was last dispatched. The value is a bias used to adjust the priority for the process. On AIX, the nice user value, makes a process less favored than it otherwise would be, has a range of 0-40 with a default value of 20. The value of PUSER is always added to the value of nice to weight the user process down below the range of priorities expected to be in use by system jobs like the scheduler and special wait queues.

The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval. If this metric is reported for a kernel thread, the percentage value is for that single kernel thread. If this metric is reported for a process, the percentage value is calculated with the sum of the wait and alive times of all of its kernel threads. For example, if a process has 2 kernel threads, one sleeping for the entire interval and one waiting on terminal input for the interval, the process wait percent values will be 50% on Sleep and 50% on Terminal. The kernel thread wait values will be 100% on Sleep for the first kernel thread and 100% on Terminal for the second kernel thread. For another example, consider the same process as above, with 2 kernel threads, one of which was created half-way through the interval, and which then slept for the remainder of the interval. The other kernel thread was waiting for terminal input for half the interval, then used the CPU actively for the remainder of the interval. The process wait percent values will be 33% on Sleep and 33% on Terminal (each one third of the total alive time). The kernel thread wait values will be 100% on Sleep for the first kernel thread and 50% on Terminal for the second kernel thread. PROC_OTHER_WAIT_TIME THREAD_OTHER_WAIT_TIME ---------------------------------- The time, in seconds, that the process or kernel thread was blocked on other (unknown) activities during the interval. This includes processes or kernel threads that were started and subsequently suspended before the midaemon was started and have not been resumed, or the block state is unknown. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. If this metric is reported for a kernel thread, the value is the wait time of that single kernel thread. If this metric is reported for a process, the value is the sum of the wait times of all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. For multi-threaded processes, the wait times can exceed the length of the measurement interval. PROC_OTHER_WAIT_TIME_CUM THREAD_OTHER_WAIT_TIME_CUM ---------------------------------- The time, in seconds, that the process or kernel thread was blocked on other (unknown) activities over the cumulative collection time. This includes processes or kernel threads that were started and subsequently suspended before the midaemon was started and have not been resumed, or the block state is unknown. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. If this metric is reported for a kernel thread, the value is the wait time of that single kernel thread. If this metric is reported for a process, the value is the sum of the wait times of all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. For multi-threaded processes, the wait times can exceed the length of the measurement interval. PROC_PAGEFAULT THREAD_PAGEFAULT ---------------------------------- The number of page faults that occurred during the interval for the process(or kernel threads, if HP-UX/Linux Kernel 2.6 and above). PROC_PAGEFAULT_RATE THREAD_PAGEFAULT_RATE ---------------------------------- The number of page faults per second that occurred during the interval for the process(or kernel threads, if HP-UX/Linux Kernel 2.6 and above). PROC_PAGEFAULT_RATE_CUM THREAD_PAGEFAULT_RATE_CUM ---------------------------------- The average number of page faults per second that occurred over the cumulative collection time for the process(or kernel threads, if HP-UX/Linux Kernel 2.6 and above). PROC_PARENT_PROC_ID THREAD_PARENT_PROC_ID ---------------------------------- The parent process' PID number. On HP-UX, this metric is specific to a process. If this metric is reported for a kernel thread, the value for its associated process is given. PROC_PIPE_WAIT_PCT THREAD_PIPE_WAIT_PCT ---------------------------------- The percentage of time the process or kernel thread was blocked on PIPE (waiting for pipe communication to complete) during the interval. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval. If this metric is reported for a kernel thread, the percentage value is for that single kernel thread. If this metric is reported for a process, the percentage value is calculated with the sum of the wait and alive times of all of its kernel threads. For example, if a process has 2 kernel threads, one sleeping for the entire interval and one waiting on terminal input for the interval, the process wait percent values will be 50% on Sleep and 50% on Terminal. The kernel thread wait values will be 100% on Sleep for the first kernel thread and 100% on Terminal for the second kernel thread. For another example, consider the same process as above, with 2 kernel threads, one of which was created half-way through the interval, and which then slept for the remainder of the interval. The other kernel thread was waiting for terminal input for half the interval, then used the CPU actively for the remainder of the interval. The process wait percent values will be 33% on Sleep and 33% on Terminal (each one third of the total alive time). The kernel thread wait values will be 100% on Sleep for the first kernel thread and 50% on Terminal for the second kernel thread. PROC_PIPE_WAIT_PCT_CUM THREAD_PIPE_WAIT_PCT_CUM ---------------------------------- The average percentage of time the process or kernel thread was blocked on PIPE (waiting for pipe communication to complete) over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval. If this metric is reported for a kernel thread, the percentage value is for that single kernel thread. If this metric is reported for a process, the percentage value is calculated with the sum of the wait and alive times of all of its kernel threads. For example, if a process has 2 kernel threads, one sleeping for the entire interval and one waiting on terminal input for the interval, the process wait percent values will be 50% on Sleep and 50% on Terminal. The kernel thread wait values will be 100% on Sleep for the first kernel thread and 100% on Terminal for the second kernel thread. For another example, consider the same process as above, with 2 kernel threads, one of which was created half-way through the interval, and which then slept for the remainder of the interval. The other kernel thread was waiting for terminal input for half the interval, then used the CPU actively for the remainder of the interval. The process wait percent values will be 33% on Sleep and 33% on Terminal (each one third of the total alive time). The kernel thread wait values will be 100% on Sleep for the first kernel thread and 50% on Terminal for the second kernel thread. PROC_PIPE_WAIT_TIME THREAD_PIPE_WAIT_TIME ---------------------------------- The time, in seconds, that the process or kernel thread was blocked on PIPE (waiting for pipe communication to complete) during the interval. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. If this metric is reported for a kernel thread, the value is the wait time of that single kernel thread. If this metric is reported for a process, the value is the sum of the wait times of all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. For multi-threaded processes, the wait times can exceed the length of the measurement interval. PROC_PIPE_WAIT_TIME_CUM THREAD_PIPE_WAIT_TIME_CUM ---------------------------------- The time, in seconds, that the process or kernel thread was blocked on PIPE (waiting for pipe communication to complete) over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. If this metric is reported for a kernel thread, the value is the wait time of that single kernel thread. If this metric is reported for a process, the value is the sum of the wait times of all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. For multi-threaded processes, the wait times can exceed the length of the measurement interval. PROC_PRI THREAD_PRI ---------------------------------- On Unix systems, this is the dispatch priority of a process (or kernel thread, if HP-UX/Linux Kernel 2.6 and above) at the end of the interval. The lower the value, the more likely the process is to be dispatched. On Windows, this is the current base priority of this process. On HP-UX, whenever the priority is changed for the selected process or kernel thread, the new value will not be reflected until the process or kernel thread is reactivated if it is currently idle (for example, SLEEPing). On HP-UX, the lower the value, the more the process or kernel thread is likely to be dispatched. Values between zero and 127 are considered to be "real-time" priorities, which the kernel does not adjust. Values above 127 are normal priorities and are modified by the kernel for load balancing. Some special priorities are used in the HP-UX kernel and subsystems for different activities. These values are described in /usr/include/sys/param.h. Priorities less than PZERO 153 are not signalable. Note that on HP-UX, many network-related programs such as inetd, biod, and rlogind run at priority 154 which is PPIPE. Just because they run at this priority does not mean they are using pipes. By examining the open files, you can determine if a process or kernel thread is using pipes. For HP-UX 10.0 and later releases, priorities between -32 and -1 can be seen for processes or kernel threads using the Posix Real-time Schedulers. When specifying a Posix priority, the value entered must be in the range from 0 through 31, which the system then remaps to a negative number in the range of -1 through -32. Refer to the rtsched man pages for more information. On a threaded operating system, such as HP-UX 11.0 and beyond, this metric represents a kernel thread characteristic. If this metric is reported for a process, the value for its last executing kernel thread is given. For example, if a process has multiple kernel threads and kernel thread one is the last to execute during the interval, the metric value for kernel thread one is assigned to the process. On AIX, values for priority range from 0 to 127. Processes running at priorities less than PZERO (40) are not signalable. On Windows, the higher the value the more likely the process or thread is to be dispatched. Values for priority range from 0 to 31. Values of 16 and above are considered to be "realtime" priorities. Threads within a process can raise and lower their own base priorities relative to the process's base priority. On Sun Systems this metric is only available on 4.1.X. PROC_PRI_WAIT_PCT THREAD_PRI_WAIT_PCT ---------------------------------- The percentage of time during the interval the process or kernel thread was blocked on priority (waiting for its priority to become high enough to get the CPU). On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval. If this metric is reported for a kernel thread, the percentage value is for that single kernel thread. If this metric is reported for a process, the percentage value is calculated with the sum of the wait and alive times of all of its kernel threads. For example, if a process has 2 kernel threads, one sleeping for the entire interval and one waiting on terminal input for the interval, the process wait percent values will be 50% on Sleep and 50% on Terminal. The kernel thread wait values will be 100% on Sleep for the first kernel thread and 100% on Terminal for the second kernel thread. For another example, consider the same process as above, with 2 kernel threads, one of which was created half-way through the interval, and which then slept for the remainder of the interval. The other kernel thread was waiting for terminal input for half the interval, then used the CPU actively for the remainder of the interval. The process wait percent values will be 33% on Sleep and 33% on Terminal (each one third of the total alive time). The kernel thread wait values will be 100% on Sleep for the first kernel thread and 50% on Terminal for the second kernel thread. PROC_PRI_WAIT_PCT_CUM THREAD_PRI_WAIT_PCT_CUM ---------------------------------- The percentage of time the process or kernel thread was blocked on priority over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval. If this metric is reported for a kernel thread, the percentage value is for that single kernel thread. If this metric is reported for a process, the percentage value is calculated with the sum of the wait and alive times of all of its kernel threads. For example, if a process has 2 kernel threads, one sleeping for the entire interval and one waiting on terminal input for the interval, the process wait percent values will be 50% on Sleep and 50% on Terminal. The kernel thread wait values will be 100% on Sleep for the first kernel thread and 100% on Terminal for the second kernel thread. For another example, consider the same process as above, with 2 kernel threads, one of which was created half-way through the interval, and which then slept for the remainder of the interval. The other kernel thread was waiting for terminal input for half the interval, then used the CPU actively for the remainder of the interval. The process wait percent values will be 33% on Sleep and 33% on Terminal (each one third of the total alive time). The kernel thread wait values will be 100% on Sleep for the first kernel thread and 50% on Terminal for the second kernel thread. PROC_PRI_WAIT_TIME THREAD_PRI_WAIT_TIME ---------------------------------- The time, in seconds, that the process or kernel thread was blocked on PRI (waiting for its priority to become high enough to get the CPU) during the interval. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. If this metric is reported for a kernel thread, the value is the wait time of that single kernel thread. If this metric is reported for a process, the value is the sum of the wait times of all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. For multi-threaded processes, the wait times can exceed the length of the measurement interval. PROC_PRI_WAIT_TIME_CUM THREAD_PRI_WAIT_TIME_CUM ---------------------------------- The time, in seconds, that the process or kernel thread was blocked on PRI (waiting for its priority to become high enough to get the CPU) over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. If this metric is reported for a kernel thread, the value is the wait time of that single kernel thread. If this metric is reported for a process, the value is the sum of the wait times of all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. For multi-threaded processes, the wait times can exceed the length of the measurement interval. PROC_PRMID THREAD_PRMID ---------------------------------- The PRM Group ID this process is assigned to. The PRM group configuration is kept in the PRM configuration file. On HP-UX, this metric is specific to a process. If this metric is reported for a kernel thread, the value for its associated process is given. PROC_PROC_ARGV1 THREAD_PROC_ARGV1 ---------------------------------- The first argument (argv[1]) of the process argument list or the second word of the command line, if present. (For kernel threads, if HP-UX/Linux Kernel 2.6 and above this metric returns the value of the associated process). The OV Performance Agent logs the first 32 characters of this metric. For releases that support the parm file javaarg flag, this metric may not be the first argument. When javaarg=true, the value of this metric is replaced (for java processes only) by the java class or jar name. This can then be useful to construct parm file java application definitions using the argv1= keyword. PROC_PROC_CMD THREAD_PROC_CMD ---------------------------------- The full command line with which the process was initiated. (For kernel threads, if HP-UX/Linux Kernel 2.6 and above this metric returns the value of the associated process). On HP-UX, the maximum length returned depends upon the version of the OS, but typically up to 1020 characters are available. On other Unix systems, the maximum length is 4095 characters. On Linux, if the command string exceeds 4096 characters, the kernel instrumentation may not report any value. If the command line contains special characters, such as carriage return and tab, these characters will be converted to , , and so on. PROC_PROC_ID THREAD_PROC_ID ---------------------------------- The process ID number (or PID) of this process(or associated process for kernel threads, if HPUX/LInux Kernel 2.6 and above) that is used by the kernel to uniquely identify the process. Process numbers are reused, so they only identify a process for its lifetime. On HP-UX, this metric is specific to a process. If this metric is reported for a kernel thread, the value for its associated process is given. PROC_PROC_NAME THREAD_PROC_NAME ---------------------------------- The process(or kernel thread, if HP-UX/Linux Kernel 2.6 and above) program name. It is limited to 16 characters. On Unix systems, this is derived from the 1st parameter to the exec(2) system call. On HP-UX, this metric is specific to a process. If this metric is reported for a kernel thread, the value for its associated process is given. On Windows, the "System Idle Process" is not reported by OVPA since Idle is a process that runs to occupy the processors when they are not executing other threads. Idle has one thread per processor. PROC_REGION_FILENAME ---------------------------------- The file path that corresponds to the front store file of a memory region. For text and data regions, this is the name of the program; for shared libraries it is the library name. Certain "special" names are displayed if there is no actual "front store" for a memory region. These special names correspond to the region type (for example, ). If the name is "", then this is a memory region without "front store," created by the system call mmap(2). If the file format includes an inode number, use the program ncheck (1M) to display the filename relative to the mount point. Sometimes files may be deleted before they are closed. In these cases, the process file table may still have the inode even though the file is not actually present and as a result, ncheck will fail. In the following example, note that the file system name has been included to avoid the overhead of searching all of the file systems for the inode number. If the following file name was displayed: and then from that display, the following ncheck command was entered: ncheck -i 926 -F vxfs /dev/root An output like the following would be generated: /dev/root: 926 /etc/utmpx The string for an inode is as follows: where: www: Is the file type: "reg" - Regular file "dir" - Directory file "blk" - Block device "chr" - Character device "lnk" - Soft file link "sock" - Socket "fifo" - FIFO xxx: Is the file domain; such as, "ufs" - Unix file system "nfs" - NFS "vxfs" - Veritas file system yyy: Is the mount point. zzz: Is the file system. On HP-UX 11.0, the file type is not shown since it will always be "reg" for regular files, which are mmappable. If a program is "hard linked" (that is, two directories pointing to the same inode), then a different name may be reported for the text and data regions than is actually running. This often happens with the HPTERM program, which is often hard-linked to HELPVIEW. Use the "-i" option of the "ls" command to see the inode numbers. PROC_REGION_LOCKED ---------------------------------- The amount of memory (in KBs unless otherwise indicated) that is locked. Memory is typically "locked" by calls to plock(2), datalock(3C), or shmctl(2). In addition to the number of pages locked, this metric includes the number of bytes (rounded up to the nearest page) used by the kernel to store the virtual memory structures allocated to track the pages in the memory region. Hence if the region pages are locked in memory, the virtual memory management structures for that region must also be locked. As a result, one could see the number of bytes locked exceed the virtual memory size of a region. This metric is currently unavailable on HP-UX 11.0. PROC_REGION_PAGE_COUNT_1_4KB ---------------------------------- The number of pages of size 4KB allocated to this memory region. PROC_REGION_PAGE_COUNT_2_16KB ---------------------------------- The number of pages of size 16KB allocated to this memory region. PROC_REGION_PAGE_COUNT_3_64KB ---------------------------------- The number of pages of size 64KB allocated to this memory region. PROC_REGION_PAGE_COUNT_4_256KB ---------------------------------- The number of pages of size 256KB allocated to this memory region. PROC_REGION_PAGE_COUNT_5_1MB ---------------------------------- The number of pages of size 1MB allocated to this memory region. PROC_REGION_PAGE_COUNT_6_4MB ---------------------------------- The number of pages of size 4MB allocated to this memory region. PROC_REGION_PAGE_COUNT_7_16MB ---------------------------------- The number of pages of size 16MB allocated to this memory region. PROC_REGION_PAGE_COUNT_8_64MB ---------------------------------- The number of pages of size 64MB allocated to this memory region. PROC_REGION_PAGE_COUNT_9_256MB ---------------------------------- The number of pages of size 256MB allocated to this memory region. Even though 11.11 and later releases support page sizes larger than 64Mb, only 11.23 and newer releases report this data. Versions older than 11.23 adjust 64Mb page counts to include larger page sizes (for instance, one 256Mb page will be counted as 4 64Mb pages). PROC_REGION_PAGE_COUNT_B_1GB ---------------------------------- The number of pages of size 1GB allocated to this memory region. Even though 11.11 and later releases support page sizes larger than 64Mb, only 11.23 and newer releases report this data. Versions older than 11.23 adjust 64Mb page counts to include larger page sizes (for instance, one 256Mb page will be counted as 4 64Mb pages). PROC_REGION_PAGE_COUNT_B_4GB ---------------------------------- The number of pages of size 4GB allocated to this memory region. Even though 11.11 and later releases support page sizes larger than 64Mb, only 11.23 and newer releases report this data. Versions older than 11.23 adjust 64Mb page counts to include larger page sizes (for instance, one 256Mb page will be counted as 4 64Mb pages). PROC_REGION_PAGE_SIZE_HINT ---------------------------------- The recommended or default size for pages allocated to this memory region. The chatr(1) command can be used to change the page size hint requested for a program's text and data regions. PROC_REGION_PRIVATE_SHARED_FLAG ---------------------------------- A text indicator of either private memory (Priv) or shared (Shared) for this memory region. Private memory is only being used by the current process. Shared memory is mapped into the address space of other processes. PROC_REGION_REF_COUNT ---------------------------------- The number of processes sharing this memory region. For private regions this value is 1. For shared regions, this value is the number of processes sharing the region. This metric is currently unavailable on HP-UX 11.0. PROC_REGION_RES ---------------------------------- The size (in KBs unless otherwise indicated) of the resident memory occupied by this memory region. On HP-UX 11.0 and beyond, this value is not affected by the reference count. The number of references is a count of the number of attachments to the memory region. Attachments, for shared regions, may come from several processes sharing the same memory, a single process with multiple attachments, or combinations of these. PROC_REGION_RES_DATA ---------------------------------- The size (in KBs unless otherwise indicated) of the total resident memory occupied by data regions of this process. This value is not affected by the reference count since all data regions are private. This metric is specific to the process as a whole and will not change its value. If this metric is used in a glance adviser script, only pick up one value. Do not sum the values since the same value is shown for all regions. PROC_REGION_RES_OTHER ---------------------------------- The size (in KBs unless otherwise indicated) of the total resident memory occupied by regions of this process that are not text, data, stack, or shared memory. On HP-UX 11.0 and beyond, this value is not affected by the reference count. This metric is specific to the process as a whole and will not change its value. If this metric is used in a glance adviser script, only pick up one value. Do not sum the values since the same value is shown for all regions. The number of references is a count of the number of attachments to the memory region. Attachments, for shared regions, may come from several processes sharing the same memory, a single process with multiple attachments, or combinations of these. PROC_REGION_RES_SHMEM ---------------------------------- The size (in KBs unless otherwise indicated) of the total resident memory occupied by shared memory regions of this process. On HP-UX 11.0 and beyond, this value is not affected by the reference count. This metric is specific to the process as a whole and will not change its value. If this metric is used in a glance adviser script, only pick up one value. Do not sum the values since the same value is shown for all regions. The number of references is a count of the number of attachments to the memory region. Attachments, for shared regions, may come from several processes sharing the same memory, a single process with multiple attachments, or combinations of these. In other words, the sum of this value for all processes exceeds the actual memory occupied since some memory is shared. PROC_REGION_RES_STACK ---------------------------------- The size (in KBs unless otherwise indicated) of the total resident memory occupied by stack regions of this process. On HP-UX, stack regions are always private and will have a reference count of one. The stack, in this case, refers to the kernel stack, not the user stack. For a threaded OS, each kernel thread will have one kernel stack. This metric is specific to the process as a whole and will not change its value. If this metric is used in a glance adviser script, only pick up one value. Do not sum the values since the same value is shown for all regions. PROC_REGION_RES_TEXT ---------------------------------- The size (in KBs unless otherwise indicated) of the total resident memory occupied by text regions of this process. On HP-UX 11.0 and beyond, this value is not affected by the reference count. This metric is specific to the process as a whole and will not change its value. If this metric is used in a glance adviser script, only pick up one value. Do not sum the values since the same value is shown for all regions. The number of references is a count of the number of attachments to the memory region. Attachments, for shared regions, may come from several processes sharing the same memory, a single process with multiple attachments, or combinations of these. In other words, the sum of this value for all processes exceeds the actual memory occupied since some memory is shared. PROC_REGION_TYPE ---------------------------------- A text name for the type of this memory region. It can be one of the following: DATA Data region LIBDAT Shared Library data LIBTXT Shared Library text STACK Stack region TEXT Text (that is, code) On HP-UX, it can also be one of the following: GRAPH Frame buffer lock page IOMAP IO region (iomap) MEMMAP Memory-mapped file, which includes shared libraries (text and data), or memory created by calls to mmap(2) NULLDR Null pointer dereference shared page (see below) RSESTA Itanium Registered stack engine region SIGSTK Signal stack region UAREA User Area region UNKNWN Region of unknown type On HP-UX, a whole page is allocated for NULL pointer dereferencing, which is reported as the NULLDR area. If the program is compiled with the "-z" option (which disallows NULL dereferencing), this area is missing. Shared libraries are accessed as memory mapped files, so that the code will show up as "MEMMAP/Shared" and data will show up as "MEMMAP/Priv". On SUN, it can also be one of the following: BSS Static initialized data MEMMAP Memory mapped files NULLDR Null pointer dereference shared page (see below). SHMEM Shared memory UNKNWN Region of unknown type On SUN, programs might have an area for NULL pointer dereferencing, which is reported as the NULLDR area. Special segment types that are supported by the kernel that are used for frame buffer devices or other purposes are typed as UNKNWN. The following kernel processes are examples of this: sched, pageout, and fsflush. PROC_REGION_VIRT ---------------------------------- The size (in KBs unless otherwise indicated) of the virtual memory occupied by this memory region. This value is not affected by the reference count. The number of references is a count of the number of attachments to the memory region. Attachments, for shared regions, may come from several processes sharing the same memory, a single process with multiple attachments, or combinations of these. PROC_REGION_VIRT_ADDRS ---------------------------------- The virtual address of this memory region displayed in hexadecimal showing the space and offset of the region. On HP-UX, this is a 64-bit (96-bit on a 64-bit OS) hexadecimal value indicating the space and space offset of the region. PROC_REGION_VIRT_DATA ---------------------------------- The size (in KBs unless otherwise indicated) of the total virtual memory occupied by data regions of this process. This value is not affected by the reference count since all data regions are private. This metric is specific to the process as a whole and will not change its value. If this metric is used in a glance adviser script, only pick up one value. Do not sum the values since the same value is shown for all regions. PROC_REGION_VIRT_OTHER ---------------------------------- The size (in KBs unless otherwise indicated) of the total virtual memory occupied by regions of this process that are not text, data, stack, or shared memory. This value is not affected by the reference count. This metric is specific to the process as a whole and will not change its value. If this metric is used in a glance adviser script, only pick up one value. Do not sum the values since the same value is shown for all regions. The number of references is a count of the number of attachments to the memory region. Attachments, for shared regions, may come from several processes sharing the same memory, a single process with multiple attachments, or combinations of these. PROC_REGION_VIRT_SHMEM ---------------------------------- The size (in KBs unless otherwise indicated) of the total virtual memory occupied by shared memory regions of this process. Note that this memory is shared by other processes and this figure is reported in their metrics also. This value is not affected by the reference count. This metric is specific to the process as a whole and will not change its value. If this metric is used in a glance adviser script, only pick up one value. Do not sum the values since the same value is shown for all regions. The number of references is a count of the number of attachments to the memory region. Attachments, for shared regions, may come from several processes sharing the same memory, a single process with multiple attachments, or combinations of these. PROC_REGION_VIRT_STACK ---------------------------------- The size (in KBs unless otherwise indicated) of the total virtual memory occupied by stack regions of this process. Stack regions are always private and will have a reference count of one. This metric is specific to the process as a whole and will not change its value. If this metric is used in a glance adviser script, only pick up one value. Do not sum the values since the same value is shown for all regions. PROC_REGION_VIRT_TEXT ---------------------------------- The size (in KBs unless otherwise indicated) of the total virtual memory occupied by text regions of this process. This value is not affected by the reference count. This metric is specific to the process as a whole and will not change its value. If this metric is used in a glance adviser script, only pick up one value. Do not sum the values since the same value is shown for all regions. PROC_RPC_WAIT_PCT THREAD_RPC_WAIT_PCT ---------------------------------- The percentage of time the process or kernel thread was blocked on RPC (waiting for remote procedure calls to complete) during the interval. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval. If this metric is reported for a kernel thread, the percentage value is for that single kernel thread. If this metric is reported for a process, the percentage value is calculated with the sum of the wait and alive times of all of its kernel threads. For example, if a process has 2 kernel threads, one sleeping for the entire interval and one waiting on terminal input for the interval, the process wait percent values will be 50% on Sleep and 50% on Terminal. The kernel thread wait values will be 100% on Sleep for the first kernel thread and 100% on Terminal for the second kernel thread. For another example, consider the same process as above, with 2 kernel threads, one of which was created half-way through the interval, and which then slept for the remainder of the interval. The other kernel thread was waiting for terminal input for half the interval, then used the CPU actively for the remainder of the interval. The process wait percent values will be 33% on Sleep and 33% on Terminal (each one third of the total alive time). The kernel thread wait values will be 100% on Sleep for the first kernel thread and 50% on Terminal for the second kernel thread. PROC_RPC_WAIT_PCT_CUM THREAD_RPC_WAIT_PCT_CUM ---------------------------------- The average percentage of time the process or kernel thread was blocked on RPC (waiting for remote procedure calls to complete) over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval. If this metric is reported for a kernel thread, the percentage value is for that single kernel thread. If this metric is reported for a process, the percentage value is calculated with the sum of the wait and alive times of all of its kernel threads. For example, if a process has 2 kernel threads, one sleeping for the entire interval and one waiting on terminal input for the interval, the process wait percent values will be 50% on Sleep and 50% on Terminal. The kernel thread wait values will be 100% on Sleep for the first kernel thread and 100% on Terminal for the second kernel thread. For another example, consider the same process as above, with 2 kernel threads, one of which was created half-way through the interval, and which then slept for the remainder of the interval. The other kernel thread was waiting for terminal input for half the interval, then used the CPU actively for the remainder of the interval. The process wait percent values will be 33% on Sleep and 33% on Terminal (each one third of the total alive time).

If this metric is reported for a kernel thread, the value is the wait time of that single kernel thread. If this metric is reported for a process, the value is the sum of the wait times of all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. For multi-threaded processes, the wait times can exceed the length of the measurement interval. PROC_RPC_WAIT_TIME_CUM THREAD_RPC_WAIT_TIME_CUM ---------------------------------- The time, in seconds, that the process or kernel thread was blocked on RPC (waiting for its remote procedure calls to complete) over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last.

PROC_RUN_TIME THREAD_RUN_TIME ---------------------------------- The elapsed time since a process (or kernel thread, if HP- UX/Linux Kernel 2.6 and above) started, in seconds. This metric is less than the interval time if the process (or kernel thread, if HP-UX/Linux Kernel 2.6 and above) was not alive during the entire first or last interval. On a threaded operating system such as HP-UX 11.0 and beyond, this metric is available for a process or kernel thread. PROC_SCHEDULER THREAD_SCHEDULER ---------------------------------- The scheduling policy for this process or kernel thread. The available scheduling policies are: HPUX - HP-UX normal timeshare NOAGE - HP-UX timeshare without usage decay RTPRIO - HP-UX Real-time FIFO - Posix First In/First Out RR - Posix Round-Robin RR2 - Posix Round-Robin with a per-priority time slice interval On a threaded operating system, such as HP-UX 11.0 and beyond, this metric represents a kernel thread characteristic. If this metric is reported for a process, the value for its last executing kernel thread is given. For example, if a process has multiple kernel threads and kernel thread one is the last to execute during the interval, the metric value for kernel thread one is assigned to the process. PROC_SEM_WAIT_PCT THREAD_SEM_WAIT_PCT ---------------------------------- The percentage of time the process or kernel thread was blocked on semaphores (waiting on a semaphore operation to complete) during the interval. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval.

PROC_SEM_WAIT_PCT_CUM THREAD_SEM_WAIT_PCT_CUM ---------------------------------- The average percentage of time the process or kernel thread was blocked on semaphores (waiting on a semaphore operation to complete) over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last.

PROC_SIGNAL_CUM THREAD_SIGNAL_CUM ---------------------------------- Number of signals seen by the current process (or kernel thread, if HP-UX) over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. PROC_SLEEP_WAIT_PCT THREAD_SLEEP_WAIT_PCT ---------------------------------- The percentage of time the process or kernel thread was blocked on SLEEP (waiting to awaken from sleep system calls) during the interval. A process or kernel thread enters the SLEEP state by putting itself to sleep using system calls such as sleep, wait, pause, sigpause, sigsuspend, poll and select. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval. If this metric is reported for a kernel thread, the percentage value is for that single kernel thread.

PROC_STOP_REASON THREAD_STOP_REASON ---------------------------------- A text string describing what caused the process (or kernel thread, if HP-UX/Linux Kernel 2.6 and above) to stop executing. For example, if the process is waiting for a CPU while higher priority processes are executing, then its block reason is PRI. A complete list of block reasons follows: String Reason for Process Block ------------------------------------ CACHE Waiting at the buffer cache level trying to lock down a buffer cache structure, or waiting for an IO operation to or from a buffer cache to complete. File system access will block on IO more often than CACHE on HP-UX 11.x. CDFS Waiting for CD-ROM file system node structure allocation or locks while accessing a CD-ROM device through the file system. died Process terminated during the interval. DISK Waiting for an IO operation to complete at the logical device manager or disk driver level. Waits from raw disk IO and diagnostic requests can be seen here. Buffered IO requests can also block on DISK, but will more often be seen waiting on "IO". CDFS access will block on "CDFS". Virtual memory activity will block on "VM". GRAPH Waiting for a graphics card or framebuf semaphore operation. INODE Waiting while accessing an inode structure. This includes inode gets and waiting due to inode locks. IO Waiting for IO to local disks, printers, tapes, or instruments to complete (above the driver, but below the buffer cache). Both file system and raw disk access can block in this state. CDFS access will block on "CDFS". Virtual memory activity will block on "VM". IPC Waiting for a process or kernel thread event (that is, waiting for a child to receive a signal). This includes both inter and intra process or kernel thread operations, such as IPC locks, kernel thread mutexes, and database IPC operations. System V message queue operations will block on "MESG", while semaphore operations will block on "SEM". JOBCL Waiting for tracing resume, debug resume, or job control start. A background process incurs this block when attempting to write to a terminal set with "stty tostop". On HP-UX 11i, scheduler activation threads (user threads) will show this block. LAN Waiting for a network IO completion. This includes waiting on the LAN hardware and low level LAN device driver. It does not include waiting on the higher level network software such as the streams based transport or NFS, which has its own stop state. MESG Waiting for a System V message queue operation such as msgrcv or msgsnd. new Process was created (via the fork/vfork system calls) during the interval. NFS Waiting for a Networked File System request to complete. This includes both NFS V2 and V3 requests. This does not include stops where kernel threads or deamons are waiting for a NFS event or request (such as biod or nfsd). These will block on SLEEP to show they are waiting for some activity. NONE Zombie process - waiting to die. OTHER The process was started before the midaemon was started and has not been resumed, or the block state is unknown. PIPE Waiting for operations involving pipes. This includes opening, closing, reading, and writing using pipes. Named pipes will block on PIPE. PRI Waiting because a higher priority process is running, or waiting for a spinlock or alpha semaphore. RPC Waiting for remote procedure call operations to complete. This includes both NFS and DCE RPC requests. SEM Waiting for a System V semaphore operation (such as semop, semget, or semctl) or waiting for a memory mapped file semaphore operation (such as msem_init or msem_lock). SLEEP Waiting because the process put itself to sleep using system calls such as sleep, wait, pause, sigpause, poll, sigsuspend and select. This is the standard stop reason for idle system daemons. SOCKT Waiting for an operation to complete while accessing a device through a socket. This is used primarily in networking code and includes all protocols using sockets (X25, UDP, TCP, and so on). STRMS Waiting for an operation to complete while accessing a "streams" device. This is the normal stop reason for kernel threads and daemons waiting for a streams event. This includes the network transport and pseudo terminal IO requests. For example, waiting for a read on a streams device or waiting for an internal streams synchronization. SYSTM Waiting for access to a system resource or lock. These resources include data structures from the LVM, VFS, UFS, JFS, and Disk Quota subsystems. "SYSTM" is the "catch-all" wait state for blocks on system resources that are not common enough or long enough to warrant their own stop state. TERM Waiting for a non-streams terminal transfer (tty or pty). VM Waiting for a virtual memory operation to complete, or waiting for free memory, or blocked while creating/ accessing a virtual memory structure. For a process or kernel thread currently running, the last reason it was stopped before obtaining the CPU is shown. On HP-UX 11.0 and beyond, mikslp.text (located in /opt/perf/lib) contains the blocking functions and their corresponding block states for use by midaemon. On a threaded operating system, such as HP-UX 11.0 and beyond, this metric represents a kernel thread characteristic. If this metric is reported for a process, the value for its last executing kernel thread is given. For example, if a process has multiple kernel threads and kernel thread one is the last to execute during the interval, the metric value for kernel thread one is assigned to the process. PROC_STOP_REASON_FLAG THREAD_STOP_REASON_FLAG ---------------------------------- A numeric value for the stop reason. This is used by scopeux instead of the ASCII string returned by PROC_STOP_REASON in order to conserve space in the log file. On a threaded operating system, such as HP-UX 11.0 and beyond, this metric represents a kernel thread characteristic. If this metric is reported for a process, the value for its last executing kernel thread is given. For example, if a process has multiple kernel threads and kernel thread one is the last to execute during the interval, the metric value for kernel thread one is assigned to the process. PROC_STREAM_WAIT_PCT THREAD_STREAM_WAIT_PCT ---------------------------------- The percentage of time the process or kernel thread was blocked on streams IO (waiting for a streams IO operation to complete) during the interval. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval. If this metric is reported for a kernel thread, the percentage value is for that single kernel thread. If this metric is reported for a process, the percentage value is calculated with the sum of the wait and alive times of all of its kernel threads. For example, if a process has 2 kernel threads, one sleeping for the entire interval and one waiting on terminal input for the interval, the process wait percent values will be 50% on Sleep and 50% on Terminal. The kernel thread wait values will be 100% on Sleep for the first kernel thread and 100% on Terminal for the second kernel thread. For another example, consider the same process as above, with 2 kernel threads, one of which was created half-way through the interval, and which then slept for the remainder of the interval. The other kernel thread was waiting for terminal input for half the interval, then used the CPU actively for the remainder of the interval. The process wait percent values will be 33% on Sleep and 33% on Terminal (each one third of the total alive time). The kernel thread wait values will be 100% on Sleep for the first kernel thread and 50% on Terminal for the second kernel thread. PROC_STREAM_WAIT_PCT_CUM THREAD_STREAM_WAIT_PCT_CUM ---------------------------------- The average percentage of time the process or thread was blocked on streams IO (waiting for a streams IO operation to complete) over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval. If this metric is reported for a kernel thread, the percentage value is for that single kernel thread. If this metric is reported for a process, the percentage value is calculated with the sum of the wait and alive times of all of its kernel threads. For example, if a process has 2 kernel threads, one sleeping for the entire interval and one waiting on terminal input for the interval, the process wait percent values will be 50% on Sleep and 50% on Terminal. The kernel thread wait values will be 100% on Sleep for the first kernel thread and 100% on Terminal for the second kernel thread. For another example, consider the same process as above, with 2 kernel threads, one of which was created half-way through the interval, and which then slept for the remainder of the interval. The other kernel thread was waiting for terminal input for half the interval, then used the CPU actively for the remainder of the interval. The process wait percent values will be 33% on Sleep and 33% on Terminal (each one third of the total alive time). The kernel thread wait values will be 100% on Sleep for the first kernel thread and 50% on Terminal for the second kernel thread. PROC_STREAM_WAIT_TIME THREAD_STREAM_WAIT_TIME ---------------------------------- The time, in seconds, that the process or kernel thread was blocked on streams IO (waiting for a streams IO operation to complete) during the interval. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. If this metric is reported for a kernel thread, the value is the wait time of that single kernel thread. If this metric is reported for a process, the value is the sum of the wait times of all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. For multi-threaded processes, the wait times can exceed the length of the measurement interval. PROC_STREAM_WAIT_TIME_CUM THREAD_STREAM_WAIT_TIME_CUM ---------------------------------- The time, in seconds, that the process or kernel thread was blocked on streams IO (waiting for a streams IO operation to complete) over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. If this metric is reported for a kernel thread, the value is the wait time of that single kernel thread. If this metric is reported for a process, the value is the sum of the wait times of all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. For multi-threaded processes, the wait times can exceed the length of the measurement interval. PROC_SWAP THREAD_SWAP ---------------------------------- The number of times the process or kernel thread was deactivated during the interval. On HP-UX, process swapping was replaced by a combination of paging and deactivation. Process deactivation occurs when the system is thrashing or when the amount of free memory falls below a critical level. The swapper then marks certain processes for deactivation and removes them from the run queue. Pages within the associated memory regions are reused or paged out by the memory management vhand process in favor of pages belonging to processes that are not deactivated. Unlike traditional process swapping, deactivated memory pages may or may not be written out to the swap area, because a process could be reactivated before the paging occurs. To summarize, a process swap-out on HP-UX is a process deactivation. A swap-in is a reactivation of a deactivated process. Swap metrics that report swap-out bytes now represent bytes paged out to swap areas from deactivated regions. Because these pages are pushed out over time based on memory demands, these counts are much smaller than HP-UX 9.x counts where the entire process was written to the swap area when it was swapped-out. Likewise, swap-in bytes now represent bytes paged in as a result of reactivating a deactivated process and reading in any pages that were actually paged out to the swap area while the process was deactivated. On HP-UX, this metric is specific to a process. If this metric is reported for a kernel thread, the value for its associated process is given. PROC_SWAP_CUM THREAD_SWAP_CUM ---------------------------------- The number of times the process or kernel thread was deactivated over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last.

On HP-UX, this metric is specific to a process. If this metric is reported for a kernel thread, the value for its associated process is given. PROC_SYS_WAIT_PCT THREAD_SYS_WAIT_PCT ---------------------------------- The percentage of time the process or kernel thread was blocked on system resources during the interval. These resources include data structures from the LVM, VFS, UFS, JFS, and Disk Quota subsystems. "SYSTM" is the "catch-all" wait state for blocks on system resources that are not common enough or long enough to warrant their own stop state. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. A percentage of time spent in a wait state is calculated as the time a kernel thread (or all kernel threads of a process) spent waiting in this state, divided by the alive time of the kernel thread (or all kernel threads of the process) during the interval. If this metric is reported for a kernel thread, the percentage value is for that single kernel thread. If this metric is reported for a process, the percentage value is calculated with the sum of the wait and alive times of all of its kernel threads. For example, if a process has 2 kernel threads, one sleeping for the entire interval and one waiting on terminal input for the interval, the process wait percent values will be 50% on Sleep and 50% on Terminal. The kernel thread wait values will be 100% on Sleep for the first kernel thread and 100% on Terminal for the second kernel thread. For another example, consider the same process as above, with 2 kernel threads, one of which was created half-way through the interval, and which then slept for the remainder of the interval.

The process wait percent values will be 33% on Sleep and 33% on Terminal (each one third of the total alive time). The kernel thread wait values will be 100% on Sleep for the first kernel thread and 50% on Terminal for the second kernel thread. PROC_SYS_WAIT_PCT_CUM THREAD_SYS_WAIT_PCT_CUM ---------------------------------- The average percentage of time the process or kernel thread was blocked on SYSTM (that is, system resources) over the cumulative collection time.

PROC_SYS_WAIT_TIME THREAD_SYS_WAIT_TIME ---------------------------------- The time, in seconds, that the process or kernel thread was blocked on SYSTM (that is, system resources) during the interval.

PROC_TERM_IO_WAIT_PCT THREAD_TERM_IO_WAIT_PCT ---------------------------------- The percentage of time the process or kernel thread was blocked on terminal IO (waiting for its terminal IO to complete) during the interval. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation.

PROC_TERM_IO_WAIT_PCT_CUM THREAD_TERM_IO_WAIT_PCT_CUM ---------------------------------- The average percentage of time the process or kernel thread was blocked on terminal IO (waiting for its terminal IO to complete) over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last.

PROC_TERM_IO_WAIT_TIME THREAD_TERM_IO_WAIT_TIME ---------------------------------- The time, in seconds, that the process or kernel thread was blocked on terminal IO (waiting for its terminal IO to complete) during the interval.

For multi-threaded processes, the wait times can exceed the length of the measurement interval. PROC_THREAD_COUNT THREAD_THREAD_COUNT ---------------------------------- The total number of kernel threads for the current process. On Linux systems with Kernel 2.5 and below, every thread has its own process ID so this metric will always be 1. On Solaris systems, this metric reflects the total number of Light Weight Processes (LWPs) associated with the process. PROC_THREAD_ID THREAD_THREAD_ID ---------------------------------- The thread ID number of this kernel thread, used to uniquely identify it. On Linux systems this metric shall be available from Linux Kernel 2.6 onwards. PROC_TIME THREAD_TIME ---------------------------------- The time the data for the process (or kernel threads, if HP- UX/Linux Kernel 2.6 and above) was collected, in local time. PROC_TOP_CPU_INDEX THREAD_TOP_CPU_INDEX ---------------------------------- The index of the process which consumed the most CPU during the interval. From this index, the process PID, process name, and CPU utilization can be obtained. (Even for kernel threads if HPUX/Linux Kernel 2.6 and above this metric returns the index of the process) This metric is used by the Performance Tools to index into the Data collection interface's internal table. This is not a metric that will be interesting to Tool users. PROC_TOP_DISK_INDEX THREAD_TOP_DISK_INDEX ---------------------------------- The index of the process which did the most physical IOs during the last interval. On HP-UX, note that NFS mounted disks are not considered in this calculation. With this index, the PID, process name, and IOs per second can be obtained. This metric is used by the Performance Tools to index into the Data collection interface's internal table. This is not a metric that will be interesting to Tool's users. PROC_TOTAL_WAIT_TIME THREAD_TOTAL_WAIT_TIME ---------------------------------- The total time, in seconds, that the process or kernel thread spent blocked during the interval. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. If this metric is reported for a kernel thread, the value is the wait time of that single kernel thread. If this metric is reported for a process, the value is the sum of the wait times of all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. For multi-threaded processes, the wait times can exceed the length of the measurement interval. PROC_TOTAL_WAIT_TIME_CUM THREAD_TOTAL_WAIT_TIME_CUM ---------------------------------- The total time that the process or kernel thread spent blocked over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On a threaded operating system, such as HP-UX 11.0 and beyond, process wait time is calculated by summing the wait times of its kernel threads. If this metric is reported for a kernel thread, the value is the wait time of that single kernel thread. If this metric is reported for a process, the value is the sum of the wait times of all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. For multi-threaded processes, the wait times can exceed the length of the measurement interval. PROC_TTY THREAD_TTY ---------------------------------- The controlling terminal for a process(or kernel threads, if HP-UX/Linux Kernel 2.6 and above). This field is blank if there is no controlling terminal. On HP-UX, Linux, and AIX, this is the same as the "TTY" field of the ps command. On all other Unix systems, the controlling terminal name is found by searching the directories provided in the /etc/ttysrch file. See man page ttysrch(4) for details. The matching criteria field ("M", "F" or "I" values) of the ttysrch file is ignored. If a terminal is not found in one of the ttysrch file directories, the following directories are searched in the order here: "/dev", "/dev/pts", "/dev/term" and "dev/xt". When a match is found in one of the "/dev" subdirectories, "/dev/" is not displayed as part of the terminal name. If no match is found in the directory searches, the major and minor numbers of the controlling terminal are displayed. In most cases, this value is the same as the "TTY" field of the ps command. On HP-UX, this metric is specific to a process. If this metric is reported for a kernel thread, the value for its associated process is given. PROC_TTY_DEV THREAD_TTY_DEV ---------------------------------- The device number of the controlling terminal for a process(or kernel threads, if HP-UX/Linux Kernel 2.6 and above). On HP-UX, this metric is specific to a process. If this metric is reported for a kernel thread, the value for its associated process is given. PROC_UID THREAD_UID ---------------------------------- The real UID (user ID number) of a process(or kernel threads, if HP-UX/Linux Kernel 2.6 and above). This is the UID returned from the getuid system call. On HP-UX, this metric is specific to a process. If this metric is reported for a kernel thread, the value for its associated process is given. PROC_USER_NAME THREAD_USER_NAME ---------------------------------- On Unix systems, this is the login account(from /etc/passwd) of a process (or kernel thread, if HP-UX/Linux Kernel 2.6 and above). If more than one account is listed in /etc/passwd with the same user ID (uid) field, the first one is used. If an account cannot be found that matches the uid field, then the uid number is returned. This would occur if the account was removed after a process was started. On Windows, this is the process owner account name, without the domain name this account resides in. On HP-UX, this metric is specific to a process. If this metric is reported for a kernel thread, the value for its associated process is given. PROC_USER_THREAD_ID THREAD_USER_THREAD_ID ---------------------------------- The user thread ID number of the last user thread to execute within the context of this process or kernel thread. User threads IDs are used to identify user-level threads of execution within the context of a process. A process may have one or more user threads even if there is only one kernel thread. PROC_USRPRI THREAD_USRPRI ---------------------------------- The user priority for the process or kernel thread is set by the kernel during scheduling. This value becomes the actual process or kernel thread priority once it returns to user mode from kernel mode. The calculation of the user priority is based on the process or kernel thread CPU usage and the nice value. On a threaded operating system, such as HP-UX 11.0 and beyond, this metric represents a kernel thread characteristic. If this metric is reported for a process, the value for its last executing kernel thread is given. For example, if a process has multiple kernel threads and kernel thread one is the last to execute during the interval, the metric value for kernel thread one is assigned to the process. PROC_VOLUNTARY_CSWITCH THREAD_VOLUNTARY_CSWITCH ---------------------------------- The number of times a process (or kernel thread, if HP-UX) has given up the CPU before an external event preempted it during the interval. Examples of voluntary switches include calls to sleep(2) and select(2). On a threaded operating system, such as HP-UX 11.0 and beyond, process usage of a resource is calculated by summing the usage of that resource by its kernel threads. If this metric is reported for a kernel thread, the value is the resource usage by that single kernel thread. If this metric is reported for a process, the value is the sum of the resource usage by all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. PROC_VOLUNTARY_CSWITCH_CUM THREAD_VOLUNTARY_CSWITCH_CUM ---------------------------------- The number of times a process (or kernel thread, if HP-UX) has given up the CPU before an external event preempted it over the cumulative collection time. Examples of voluntary switches include calls to sleep(2) and select(2). The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On a threaded operating system, such as HP-UX 11.0 and beyond, process usage of a resource is calculated by summing the usage of that resource by its kernel threads. If this metric is reported for a kernel thread, the value is the resource usage by that single kernel thread. If this metric is reported for a process, the value is the sum of the resource usage by all of its kernel threads. Alive kernel threads and kernel threads that have died during the interval are included in the summation. SYSCALL_ACTIVE_CUM ---------------------------------- The number of system calls used on the system. All calls used over the cumulative collection time are included in this count. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. Due to the system call instrumentation on HP-UX, the fork and vfork system calls are double counted. In the case of fork and vfork, one process starts the system call, but two processes exit. HP-UX lightweight system calls, such as umask, do not show up in the GlancePlus System Calls display, but will get added to the global system call rates. If a process is being traced (debugged) using standard debugging tools (such as adb or xdb), all system calls used by that process will show up in the System Calls display while being traced. SYSCALL_CALL_COUNT ---------------------------------- The number of system calls made to this function during the interval. They are assessed when the system call stub returns control back to the calling program/routine. Due to the system call instrumentation on HP-UX, the fork and vfork system calls are double counted. In the case of fork and vfork, one process starts the system call, but two processes exit. HP-UX lightweight system calls, such as umask, do not show up in the GlancePlus System Calls display, but will get added to the global system call rates. If a process is being traced (debugged) using standard debugging tools (such as adb or xdb), all system calls used by that process will show up in the System Calls display while being traced. SYSCALL_CALL_COUNT_CUM ---------------------------------- The number of system calls made to this function over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last.

If a process is being traced (debugged) using standard debugging tools (such as adb or xdb), all system calls used by that process will show up in the System Calls display while being traced. SYSCALL_CALL_ID ---------------------------------- The ID number of this system call. System calls are sequentially numbered starting with one. SYSCALL_CALL_NAME ---------------------------------- The system call name. SYSCALL_CALL_RATE ---------------------------------- The number of system calls per second made to this function during the last interval. They are assessed when the system call stub returns control back to the calling program/routine. Due to the system call instrumentation on HP-UX, the fork and vfork system calls are double counted. In the case of fork and vfork, one process starts the system call, but two processes exit. HP-UX lightweight system calls, such as umask, do not show up in the GlancePlus System Calls display, but will get added to the global system call rates. If a process is being traced (debugged) using standard debugging tools (such as adb or xdb), all system calls used by that process will show up in the System Calls display while being traced. SYSCALL_CALL_RATE_CUM ---------------------------------- The average number of system calls per second made to this function over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. Due to the system call instrumentation on HP-UX, the fork and vfork system calls are double counted. In the case of fork and vfork, one process starts the system call, but two processes exit. HP-UX lightweight system calls, such as umask, do not show up in the GlancePlus System Calls display, but will get added to the global system call rates. If a process is being traced (debugged) using standard debugging tools (such as adb or xdb), all system calls used by that process will show up in the System Calls display while being traced. SYSCALL_CPU_TOTAL_TIME ---------------------------------- The CPU time, in seconds, during the interval spent executing this system calls. SYSCALL_CPU_TOTAL_TIME_CUM ---------------------------------- The CPU time, in seconds, over the cumulative collection time spent executing this system calls. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. SYSCALL_INTERVAL ---------------------------------- The amount of time in the interval. SYSCALL_INTERVAL_CUM ---------------------------------- The amount of time over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. TBL_BUFFER_CACHE_AVAIL ---------------------------------- The size (in KBs unless otherwise specified) of the file system buffer cache on the system. On HP-UX, these buffers are used for all file system IO operations, as well as all other block IO operations in the system (exec, mount, inode reading, and some device drivers). On HP-UX, if dynamic buffer cache is enabled, the system allocates a percentage of available memory not less than dbc_min_pct nor more than dbc_max_pct, depending on the system needs at any given time. On systems with a static buffer cache, this value will remain equal to bufpages, or not less than dbc_min_pct nor more than dbc_max_pct. On SUN, this value is obtained by multiplying the system page size times the number of buffer headers (nbuf). For example, on a SPARCstation 10 the buffer size is usually (200 (page size buffers) * 4096 (bytes/page) = 800 KB). NOTE: (For SUN systems with VERITAS File System installed) Veritas implemented their Direct I/O feature in their file system to provide mechanism for bypassing the Unix system buffer cache while retaining the on disk structure of a file system. The way in which Direct I/O works involves the way the system buffer cache is handled by the Unix OS. Once the VERITAS file system returns with the requested block, instead of copying the content to a system buffer page, it copies the block into the application's buffer space. That's why if you have installed vxfs on your system, the TBL_BUFFER_CACHE_AVAIL can exceed the TBL_BUFFER_CACHE_HWM metric. On SUN, the buffer cache is a memory pool used by the system to cache inode, indirect block and cylinder group related disk accesses. This is different from the traditional concept of a buffer cache that also holds file system data. On Solaris 5.X, as file data is cached, accesses to it show up as virtual memory IOs. File data caching occurs through memory mapping managed by the virtual memory system, not through the buffer cache. The "nbuf" value is dynamic, but it is very hard to create a situation where the memory cache metrics change, since most systems have more than adequate space for inode, indirect block, and cylinder group data caching. This cache is more heavily utilized on NFS file servers. On AIX, this cache is used for all block IO. TBL_BUFFER_CACHE_HIGH ---------------------------------- The highest size (in KBs unless otherwise specified) of the buffer cache used in any one interval over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_BUFFER_CACHE_MAX ---------------------------------- The maximum size (in KBs unless otherwise specified) of the buffer cache. On systems with a dynamic buffer cache, the cache does not exceed this limit. This corresponds to the kernel configuration parameter "dbc_max_pct". On systems with a dynamic buffer cache, the cache does not increase above this limit. On systems with a fixed buffer cache, the cache size is equal to the value reported, which is based on the dbc_max_pct or bufpages settings. TBL_BUFFER_CACHE_MIN ---------------------------------- The minimum size (in KBs unless otherwise specified) of the buffer cache. On systems with a dynamic buffer cache, the cache does not shrink below this limit. This corresponds to the kernel configuration parameter "dbc_min_pct". On systems with a dynamic buffer cache, the cache does not shrink below this limit. On systems with a fixed buffer cache, the cache size is equal to the value reported, which is based on the dbc_min_pct or bufpages settings. TBL_BUFFER_CACHE_USED ---------------------------------- The size (in KBs unless otherwise specified) of the sum of the currently used buffers. On HP-UX and AIX, this is normally greater than the amount requested due to internal fragmentation of the buffer cache. Since this is a cache, it is normal for it to be filled. The buffer cache is used to stage all block IOs to disk. On HP-UX, in a dynamic buffer cache configuration, this metric is always equal to TBL_BUFFER_CACHE_AVAIL. With dynamic buffer cache, the system allocates a percentage of available memory not less than dbc_min_pct nor more than dbc_max_pct, depending on the system needs at any given time. On systems with a static buffer cache, this value will remain equal to bufpages, or not less than dbc_min_pct nor more than dbc_max_pct. With a static buffer cache, this metric shows the amount of memory within the configured size that is actually used. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_BUFFER_HEADER_AVAIL ---------------------------------- This is the maximum number of headers pointing to buffers in the file system buffer cache. On HP-UX, this is the configured number, not the maximum number. This can be set by the "nbuf" kernel configuration parameter. nbuf is used to determine the maximum total number of buffers on the system. On HP-UX, these are used to manage the buffer cache, which is used for all block IO operations. When nbuf is zero, this value depends on the "bufpages" size of memory (see System Administration Tasks manual). A value of "na" indicates either a dynamic buffer cache configuration, or the nbuf kernel parameter has been left unconfigured and allowed to "float" with the bufpages parameter. This is not a maximum available value in a fixed buffer cache configuration. Instead, it is the initial configured value. The actual number of used buffer headers can grow beyond this initial value. On SUN, this value is "nbuf". On SUN, the buffer cache is a memory pool used by the system to cache inode, indirect block and cylinder group related disk accesses. This is different from the traditional concept of a buffer cache that also holds file system data. On Solaris 5.X, as file data is cached, accesses to it show up as virtual memory IOs. File data caching occurs through memory mapping managed by the virtual memory system, not through the buffer cache. The "nbuf" value is dynamic, but it is very hard to create a situation where the memory cache metrics change, since most systems have more than adequate space for inode, indirect block, and cylinder group data caching. This cache is more heavily utilized on NFS file servers. TBL_BUFFER_HEADER_USED ---------------------------------- The number of buffer headers currently in use. On HP-UX, this dynamic value will rarely change once the system boots. During the system bootup, the kernel allocates a large number of buffer headers and the count is likely to stay at that value after the bootup completes. If the value increases beyond the initial boot value, it will not decrease. Buffer headers are allocated in kernel memory, not user memory, and therefore, will not decrease. This value can exceed the available or configured number of buffer headers in a fixed buffer cache configuration. On SUN, the buffer cache is a memory pool used by the system to cache inode, indirect block and cylinder group related disk accesses. This is different from the traditional concept of a buffer cache that also holds file system data. On Solaris 5.X, as file data is cached, accesses to it show up as virtual memory IOs. File data caching occurs through memory mapping managed by the virtual memory system, not through the buffer cache. The "nbuf" value is dynamic, but it is very hard to create a situation where the memory cache metrics change, since most systems have more than adequate space for inode, indirect block, and cylinder group data caching. This cache is more heavily utilized on NFS file servers. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_BUFFER_HEADER_UTIL ---------------------------------- The percentage of buffer headers currently used. On HP-UX, a value of "na" indicates either a dynamic buffer cache configuration, or the nbuf kernel parameter has been left unconfigured and allowed to "float" with the bufpages parameter. On SUN, the buffer cache is a memory pool used by the system to cache inode, indirect block and cylinder group related disk accesses. This is different from the traditional concept of a buffer cache that also holds file system data. On Solaris 5.X, as file data is cached, accesses to it show up as virtual memory IOs. File data caching occurs through memory mapping managed by the virtual memory system, not through the buffer cache. The "nbuf" value is dynamic, but it is very hard to create a situation where the memory cache metrics change, since most systems have more than adequate space for inode, indirect block, and cylinder group data caching. This cache is more heavily utilized on NFS file servers. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_BUFFER_HEADER_UTIL_HIGH ---------------------------------- The highest percentage of buffer header used in any one interval over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On HP-UX, a value of "na" indicates either a dynamic buffer cache configuration, or the nbuf kernel parameter has been left unconfigured and allowed to "float" with the bufpages parameter. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_DNLC_CACHE_AVAIL ---------------------------------- The configured number of entries in the incore directory name cache. On HP-UX, the directory name lookup cache is used to minimize sequential searches through directory entries for pathname components during pathname to inode translations. Such translations are done whenever a file is accessed through its filename. The cache holds the inode cache table offset for recently referenced pathname components. Pathname components that exceed 15 characters are not cached. Any HP-UX system call that includes a path parameter can result in directory name lookup cache activity, including but not limited to system calls such as open, stat, exec, lstat, unlink. Each component of a path parameter is parsed and converted to an inode separately, therefore several dnlc hits per path are possible. High directory name cache hit rates on HP-UX will be seen on systems where pathname component requests are frequently repeated. For example, when users or applications work in the same directory where they repeatedly list or open the same files, cache hit rates will be high. Unusually low cache hit rates might be seen on HP-UX systems where users or applications access many different directories in no particular pattern. Low cache hit rates can also be an indicator of an underconfigured inode cache. When an inode cache is too small, the kernel will more frequently have to flush older inode cache and their corresponding directory name cache entries in order to make room for new inode cache entries. On HP-UX, the directory name lookup cache is static in size and is allocated in kernel memory. As a result, it is not affected by user memory constraints. The size of the cache is stored in the kernel variable "ncsize" and is not directly tunable by the system administrator; however, it can be changed indirectly by tuning other tables used in the formula to compute the "ncsize". The formula is: ncsize = MAX(((nproc+16+maxusers)+ 32+(2*npty)),ninode) Note that ncsize is always >= ninode which is the default size of the inode cache. This is because the directory name cache contains inode table offsets for each cached pathname component. TBL_FILE_LOCK_AVAIL ---------------------------------- The configured number of file or record locks that can be allocated on the system. Files and/or records are locked by calls to lockf(2). On Linux kernel versions 2.4 and above, available file orrecord locks is a dynamic value which can grow upto max unsigned long. TBL_FILE_LOCK_USED ---------------------------------- The number of file or record locks currently in use. One file can have multiple locks. Files and/or records are locked by calls to lockf(2). On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_FILE_LOCK_UTIL ---------------------------------- The percentage of configured file or record locks currently in use. On Linux 2.4 and above kernel versions, this may not give correct picture as file or record locks available may change dynamically and can grow upto max unsigned long. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_FILE_LOCK_UTIL_HIGH ---------------------------------- The highest percentage of configured file or record locks that have been in use during any one interval over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_FILE_TABLE_AVAIL ---------------------------------- The number of entries in the file table. On HP-UX and AIX, this is the configured maximum number of the file table entries used by the kernel to manage open file descriptors. On HP-UX, this is the sum of the "nfile" and "file_pad" values used in kernel generation. On SUN, this is the number of entries in the file cache. This is a size. All entries are not always in use. The cache size is dynamic. Entries in this cache are used to manage open file descriptors. They are reused as files are closed and new ones are opened. The size of the cache will go up or down in chunks as more or less space is required in the cache. On AIX, the file table entries are dynamically allocated by the kernel if there is no entry available. These entries are allocated in chunks. TBL_FILE_TABLE_USED ---------------------------------- The number of entries in the file table currently used by file descriptors. On SUN, this is the number of file cache entries currently used by file descriptors. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_FILE_TABLE_UTIL ---------------------------------- The percentage of file table entries currently used by file descriptors. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_FILE_TABLE_UTIL_HIGH ---------------------------------- The highest percentage of entries in the file table used by file descriptors in any one interval over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_INODE_CACHE_AVAIL ---------------------------------- On HP-UX, this is the configured total number of entries for the incore inode tables on the system. For HP-UX releases prior to 11.2x, this value reflects only the HFS inode table. For subsequent HP-UX releases, this value is the sum of inode tables for both HFS and VxFS file systems (ninode plus vxfs_ninode). On HP-UX, file system directory activity is done through inodes that are stored on disk. The kernel keeps a memory cache of active and recently accessed inodes to reduce disk IOs. When a file is opened through a pathname, the kernel converts the pathname to an inode number and attempts to obtain the inode information from the cache based on the filesystem type. If the inode entry is not in the cache, the inode is read from disk into the inode cache. On HP-UX, the number of used entries in the inode caches are usually at or near the capacity. This does not necessarily indicate that the configured sizes are too small because the tables may contain recently used inodes and inodes referenced by entries in the directory name lookup cache. When a new inode cache entry is required and a free entry does not exist, inactive entries referenced by the directory name cache are used. If after freeing inode entries only referenced by the directory name cache does not create enough free space, the message "inode: table is full" message may appear on the console. If this occurs, increase the size of the kernel parameter, ninode. Low directory name cache hit ratios may also indicate an underconfigured inode cache. On HP-UX, the default formula for the ninode size is: ninode = ((nproc+16+maxusers)+32+ (2*npty)+(4*num_clients)) On all other Unix systems, this is the number of entries in the inode cache. This is a size. All entries are not always in use. The cache size is dynamic. Entries in this cache are reused as files are closed and new ones are opened. The size of the cache will go up or down in chunks as more or less space is required in the cache. Inodes are used to store information about files within the file system. Every file has at least two inodes associated with it (one for the directory and one for the file itself). The information stored in an inode includes the owners, timestamps, size, and an array of indices used to translate logical block numbers to physical sector numbers. There is a separate inode maintained for every view of a file, so if two processes have the same file open, they both use the same directory inode, but separate inodes for the file. TBL_INODE_CACHE_HIGH ---------------------------------- On HP-UX and OSF1, this is the highest number of inodes that have been used in any one interval over the cumulative collection time. On HP-UX, file system directory activity is done through inodes that are stored on disk. The kernel keeps a memory cache of active and recently accessed inodes to reduce disk IOs. When a file is opened through a pathname, the kernel converts the pathname to an inode number and attempts to obtain the inode information from the cache based on the filesystem type. If the inode entry is not in the cache, the inode is read from disk into the inode cache. On HP-UX, the number of used entries in the inode caches are usually at or near the capacity. This does not necessarily indicate that the configured sizes are too small because the tables may contain recently used inodes and inodes referenced by entries in the directory name lookup cache. When a new inode cache entry is required and a free entry does not exist, inactive entries referenced by the directory name cache are used. If after freeing inode entries only referenced by the directory name cache does not create enough free space, the message "inode: table is full" message may appear on the console. If this occurs, increase the size of the kernel parameter, ninode. Low directory name cache hit ratios may also indicate an underconfigured inode cache. On HP-UX, the default formula for the ninode size is: ninode = ((nproc+16+maxusers)+32+ (2*npty)+(4*num_clients)) On all other Unix systems, this is the largest size of the inode cache in any one interval over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_INODE_CACHE_USED ---------------------------------- The number of inode cache entries currently in use. On HP-UX, this is the number of "non-free" inodes currently used. Since the inode table contains recently closed inodes as well as open inodes, the table often appears to be fully utilized. When a new entry is needed, one can usually be found by reusing one of the recently closed inode entries. On HP-UX, file system directory activity is done through inodes that are stored on disk. The kernel keeps a memory cache of active and recently accessed inodes to reduce disk IOs. When a file is opened through a pathname, the kernel converts the pathname to an inode number and attempts to obtain the inode information from the cache based on the filesystem type. If the inode entry is not in the cache, the inode is read from disk into the inode cache. On HP-UX, the number of used entries in the inode caches are usually at or near the capacity. This does not necessarily indicate that the configured sizes are too small because the tables may contain recently used inodes and inodes referenced by entries in the directory name lookup cache. When a new inode cache entry is required and a free entry does not exist, inactive entries referenced by the directory name cache are used. If after freeing inode entries only referenced by the directory name cache does not create enough free space, the message "inode: table is full" message may appear on the console. If this occurs, increase the size of the kernel parameter, ninode. Low directory name cache hit ratios may also indicate an underconfigured inode cache. On HP-UX, the default formula for the ninode size is: ninode = ((nproc+16+maxusers)+32+ (2*npty)+(4*num_clients)) On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_MSG_BUFFER_AVAIL ---------------------------------- The maximum achievable size (in KBs unless otherwise specified) of the message queue buffer pool on the system. Each message queue can contain many buffers which are created whenever a program issues a msgsnd(2) call. Each of these buffers is allocated from this buffer pool. Refer to the ipcs(1) man page for more information. This value is determined by taking the product of the three kernel configuration variables "msgseg", "msgssz" and "msgmni". On SUN, the InterProcess Communication facilities are dynamically loadable. If the amount available is zero, this facility was not loaded when data collection began, and its data is not obtainable. The data collector is unable to determine that a facility has been loaded once data collection has started. If you know a new facility has been loaded, restart the data collection, and the data for that facility will be collected. See ipcs(1) to report on interprocess communication resources. TBL_MSG_BUFFER_HIGH ---------------------------------- The largest size (in KBs unless otherwise specified) of the message queues in any one interval over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_MSG_BUFFER_USED ---------------------------------- The current total size (in KBs unless otherwise specified) of all IPC message buffers. These buffers are created by msgsnd(2) calls and released by msgrcv(2) calls. On HP-UX and OSF1, this field corresponds to the CBYTES field of the "ipcs -qo" command. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_MSG_TABLE_AVAIL ---------------------------------- The configured maximum number of message queues that can be allocated on the system. A message queue is allocated by a program using the msgget(2) call. Refer to the ipcs(1) man page for more information. On SUN, the InterProcess Communication facilities are dynamically loadable. If the amount available is zero, this facility was not loaded when data collection began, and its data is not obtainable. The data collector is unable to determine that a facility has been loaded once data collection has started. If you know a new facility has been loaded, restart the data collection, and the data for that facility will be collected. See ipcs(1) to report on interprocess communication resources. TBL_MSG_TABLE_USED ---------------------------------- On HP-UX, this is the number of message queues currently in use. On all other Unix systems, this is the number of message queues that have been built. A message queue is allocated by a program using the msgget(2) call. See ipcs(1) to list the message queues. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_MSG_TABLE_UTIL ---------------------------------- The percentage of configured message queues currently in use. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_MSG_TABLE_UTIL_HIGH ---------------------------------- The highest percentage of configured message queues that have been in use during any one interval over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_PROC_TABLE_AVAIL ---------------------------------- The configured maximum number of the proc table entries used by the kernel to manage processes. This number includes both free and used entries. On HP-UX, this is set by the NPROC value during system generation. AIX has a "dynamic" proc table, which means that AVAIL has been set higher than should ever be needed. TBL_PROC_TABLE_USED ---------------------------------- The number of entries in the proc table currently used by processes. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_PROC_TABLE_UTIL ---------------------------------- The percentage of proc table entries currently used by processes. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_PROC_TABLE_UTIL_HIGH ---------------------------------- The highest percentage of entries in the proc table used by processes in any one interval over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_PTY_AVAIL ---------------------------------- The configured number of entries used by the pseudo-teletype driver on the system. This limits the number of pty logins possible. For HP-UX, both telnet and rlogin use streams devices. Note: On Solaris 8, by default, the number of ptys is unlimited but restricted by the size of RAM. If the number of ptys is unlimited, this metric is reported as "na". TBL_PTY_USED ---------------------------------- The number of pseudo-teletype driver (pty) entries currently in use. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_PTY_UTIL ---------------------------------- The percentage of configured pseudo-teletype driver (pty) entries currently in use. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_PTY_UTIL_HIGH ---------------------------------- The highest percentage of configured pseudo-teletype driver (pty) entries in use during any one interval over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_SEM_TABLE_AVAIL ---------------------------------- The configured number of semaphore identifiers (sets) that can be allocated on the system. On SUN, the InterProcess Communication facilities are dynamically loadable. If the amount available is zero, this facility was not loaded when data collection began, and its data is not obtainable. The data collector is unable to determine that a facility has been loaded once data collection has started. If you know a new facility has been loaded, restart the data collection, and the data for that facility will be collected. See ipcs(1) to report on interprocess communication resources. TBL_SEM_TABLE_USED ---------------------------------- On HP-UX, this is the number of semaphore identifiers currently in use. On all other Unix systems, this is the number of semaphore identifiers that have been built. A semaphore identifier is allocated by a program using the semget(2) call. See ipcs(1) to list semaphores. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_SEM_TABLE_UTIL ---------------------------------- The percentage of configured semaphores identifiers currently in use. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_SEM_TABLE_UTIL_HIGH ---------------------------------- The highest percentage of configured semaphore identifiers that have been in use during any one interval over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_SHMEM_ACTIVE ---------------------------------- The size (in KBs unless otherwise specified) of the shared memory segments that have running processes attached to them. This may be less than the amount of shared memory used on the system because a shared memory segment may exist and not have any process attached to it. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_SHMEM_AVAIL ---------------------------------- The maximum achievable size (in MB unless otherwise specified) of the shared memory pool on the system. This is a theoretical maximum determined by multiplying the configured maximum number of shared memory entries (shmmni) by the maximum size of each shared memory segment (shmmax). Your system may not have enough virtual memory to actually reach this theoretical limit - one cannot allocate more shared memory than the available reserved space configured for virtual memory. It should be noted that this value does not include any architectural limitations. (For example, on a 32-bit kernel, there is an addressing limit of 1.75 GB.) On SUN, the InterProcess Communication facilities are dynamically loadable. If the amount available is zero, this facility was not loaded when data collection began, and its data is not obtainable. The data collector is unable to determine that a facility has been loaded once data collection has started. If you know a new facility has been loaded, restart the data collection, and the data for that facility will be collected. See ipcs(1) to report on interprocess communication resources. TBL_SHMEM_REQUESTED ---------------------------------- The size (in KBs unless otherwise specified) of the sum of the currently requested shared memory segments. This may be more than shared memory used if any segments are swapped out. It also may be less than shared memory used due to internal fragmentation of the shared memory pool. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_SHMEM_TABLE_AVAIL ---------------------------------- The configured number of shared memory segments that can be allocated on the system. On SUN, the InterProcess Communication facilities are dynamically loadable. If the amount available is zero, this facility was not loaded when data collection began, and its data is not obtainable. The data collector is unable to determine that a facility has been loaded once data collection has started. If you know a new facility has been loaded, restart the data collection, and the data for that facility will be collected. See ipcs(1) to report on interprocess communication resources. TBL_SHMEM_TABLE_USED ---------------------------------- On HP-UX, this is the number of shared memory segments currently in use. On all other Unix systems, this is the number of shared memory segments that have been built. This includes shared memory segments with no processes attached to them. A shared memory segment is allocated by a program using the shmget(2) call. Also refer to ipcs(1). On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_SHMEM_TABLE_UTIL ---------------------------------- The percentage of configured shared memory segments currently in use. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_SHMEM_TABLE_UTIL_HIGH ---------------------------------- The highest percentage of configured shared memory segments that have been in use during any one interval over the cumulative collection time. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TBL_SHMEM_USED ---------------------------------- The size (in KBs unless otherwise specified) of the shared memory segments. Additionally, it includes memory segments to which no processes are attached. If a shared memory segment has zero attachments, the space may not always be allocated in memory. See ipcs(1) to list shared memory segments. On Unix systems, this metric is updated every 30 seconds or the sampling interval, whichever is greater. TTBIN_TRANS_COUNT TT_CLIENT_BIN_TRANS_COUNT ---------------------------------- The number of completed transactions in this range during the last interval. TTBIN_TRANS_COUNT_CUM TT_CLIENT_BIN_TRANS_COUNT_CUM ---------------------------------- The number of completed transactions in this range over the cumulative collection time.

TTBIN_UPPER_RANGE ---------------------------------- The upper range (transaction time) for this TT bin. There are a maximum of nine user-defined transaction response time bins (TTBIN_UPPER_RANGE). The last bin, which is not specified in the transaction configuration file (ttdconf.mwc on Windows or ttd.conf on UNIX platforms), is the overflow bin and will always have a value of -2 (overflow). Note that the values specified in the transaction configuration file cannot exceed 2147483.6, which is the number of seconds in 24.85 days. If the user specifies any values greater than 2147483.6, the numbers reported for those bins or Service Level Objectives (SLO) will be -2. TT_ABORT TT_CLIENT_ABORT ---------------------------------- The number of aborted transactions during the last interval for this transaction. TT_ABORT_CUM TT_CLIENT_ABORT_CUM ---------------------------------- The number of aborted transactions over the cumulative collection time for this transaction.

If there is only one completed transaction instance during an interval, then the resources attributed to the transaction will represent the resources used by the process between its call to arm_start and arm_stop, even if arm_start was called before the current interval. Thus, the resource usage time or wall time per transaction can exceed the current collection interval time. If there are several completed transaction instances during an interval for a given transaction, then the resources attributed to the transaction will represent an average for all completed instances during the interval.

The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last. Cumulative per-transaction performance resource metrics represent an average for all completed instances of the given transaction over the cumulative collection time. If there are no completed transaction instances over the cumulative collection time, then there are no resources accounted, even though there may be in-progress transactions using resources which have not completed. Resource metrics for in-progress transactions will be shown in the interval after they complete (that is, after the process has called arm_stop). If there is only one completed transaction instance over the cumulative collection time, then the resources attributed to the transaction will represent the resources used by the process between its call to arm_start and arm_stop, even if arm_start was called before the current interval. Thus, the resource usage time or wall time per transaction can exceed the current collection interval time. If there are several completed transaction instances over the cumulative collection time for a given transaction, then the resources attributed to the transaction will represent an average for all completed instances over the cumulative collection time. To obtain the total accumulated resource consumption for all completed transactions over the cumulative collection time, multiply the resource metric by the number of completed transaction instances over the cumulative collection time (TT_COUNT_CUM). TT_CPU_TOTAL_TIME_PER_TRAN ---------------------------------- The average total CPU time, in seconds, consumed by each completed instance of the transaction during the interval. Total CPU time is the sum of the CPU time components for a process or kernel thread, including system, user, context switch, interrupt processing, realtime, and nice utilization values. Per-transaction performance resource metrics represent an average for all completed instances of the given transaction during the interval. If there are no completed transaction instances during an interval, then there are no resources accounted, even though there may be in-progress transactions using resources which have not completed. Resource metrics for in-progress transactions will be shown in the interval after they complete (that is, after the process has called arm_stop). If there is only one completed transaction instance during an interval, then the resources attributed to the transaction will represent the resources used by the process between its call to arm_start and arm_stop, even if arm_start was called before the current interval.

If there are several completed transaction instances during an interval for a given transaction, then the resources attributed to the transaction will represent an average for all completed instances during the interval. To obtain the total accumulated resource consumption for all completed transactions during an interval, multiply the resource metric by the number of completed transaction instances during the interval (TT_COUNT). TT_CPU_TOTAL_TIME_PER_TRAN_CUM ---------------------------------- The average total CPU time consumed by each completed instance of the transaction over the cumulative collection time. CPU time is in seconds unless otherwise specified. The cumulative collection time is defined from the point in time when either: a) the process (or kernel thread, if HP- UX) was first started, or b) the performance tool was first started, or c) the cumulative counters were reset (relevant only to GlancePlus, if available for the given platform), whichever occurred last.

Thus, the resource usage time or wall time per transaction can exceed the current collection interval time. If there are several completed transaction instances over the cumulative collection time for a given transaction, then the resources attributed to the transaction will represent an average for all completed instances over the cumulative collection time. To obtain the total accumulated resource consumption for all completed transactions over the cumulative collection time, multiply the resource metric by the number of completed transaction instances over the cumulative collection time (TT_COUNT_CUM). TT_CPU_USER_MODE_TIME_PER_TRAN ---------------------------------- The average time, in seconds, each completed instance of the transaction was using the CPU in user mode during the interval. User CPU is the time spent in user mode at a normal priority, at real-time priority (on HP-UX, AIX, and Windows systems), and at a nice priority. Per-transaction performance resource metrics represent an average for all completed instances of the given transaction during the interval. If there are no completed transaction instances during an interval, then there are no resources accounted, even though there may be in-progress transactions using resources which have not completed. Resource metrics for in-progress transactions will be shown in the interval after they complete (that is, after the process has called arm_stop).

TT_DISK_FS_READ_PER_TRAN ---------------------------------- The average number of file system physical disk reads made by each completed instance of the transaction during the interval. Only local disks are counted in this measurement. NFS devices are excluded. These are physical reads generated by user file system access and do not include virtual memory reads, system reads (inode access), or reads relating to raw disk access. An exception is user files accessed via the mmap(2) call, which does not show their physical reads in this category. They appear under virtual memory reads. "Disk" in this instance refers to any locally attached physical disk drives (that is, "spindles") that may hold file systems and/or swap. NFS mounted disks are not included in this list. Per-transaction performance resource metrics represent an average for all completed instances of the given transaction during the interval.

TT_DISK_FS_WRITE_PER_TRAN ---------------------------------- The average number of file system physical disk writes made by each completed instance of the transaction during the interval. Only local disks are counted in this measurement. NFS devices are excluded. These are physical writes generated by user file system access and do not include virtual memory writes, system writes (inode updates), or writes relating to raw disk access. An exception is user files accessed via the mmap(2) call, which does not show their physical writes in this category. They appear under virtual memory writes. "Disk" in this instance refers to any locally attached physical disk drives (that is, "spindles") that may hold file systems and/or swap. NFS mounted disks are not included in this list. On HP-UX, since this value is reported by the drivers, multiple physical requests that have been collapsed to a single physical operation (due to driver IO merging) are only counted once. Per-transaction performance resource metrics represent an average for all completed instances of the given transaction during the interval. If there are no completed transaction instances during an interval, then there are no resources accounted, even though there may be in-progress transactions using resources which have not completed.

TT_DISK_LOGL_IO_PER_TRAN ---------------------------------- The average number of logical IOs made by (or for) each completed instance of the transaction during the interval. NFS mounted disks are not included in this list. "Disk" refers to a physical drive (that is, "spindle"), not a partition on a drive (unless the partition occupies the entire physical disk). On many Unix systems, logical disk IOs are measured by counting the read and write system calls that are directed to disk devices. Also counted are read and write system calls made indirectly through other system calls, including readv, recvfrom, recv, recvmsg, ipcrecvcn, recfrom, writev, send, sento, sendmsg, and ipcsend. Per-transaction performance resource metrics represent an average for all completed instances of the given transaction during the interval.

Cumulative per-transaction performance resource metrics represent an average for all completed instances of the given transaction over the cumulative collection time. If there are no completed transaction instances over the cumulative collection time, then there are no resources accounted, even though there may be in-progress transactions using resources which have not completed. Resource metrics for in-progress transactions will be shown in the interval after they complete (that is, after the process has called arm_stop). If there is only one completed transaction instance over the cumulative collection time, then the resources attributed to the transaction will represent the resources used by the process between its call to arm_start and arm_stop, even if arm_start was called before the current interval.

Glossary ======== alarm ---------------------------------- A signal that an event has occurred. The signal can be either a notification or an automatically triggered action. The event can be a pre-defined threshold that is exceeded, a network node in trouble, and so on. Alarm information can be sent to Network Node Manager (NNM) and OpenView Operations (OVO). Alarms can also be identified in historical log file data. alarm generator ---------------------------------- The service that handles the communication of alarm information. It consists of the perfalarm and the agdb database that it manages. The agdb database contains of list of nodes (if any) to which alarms are communicated, and various on/off flags that are set to define when and where the alarm information is sent. alarmdef file ---------------------------------- The file containing the alarm definitions in which alarm conditions are specified. alert ---------------------------------- A message sent when alarm conditions or conditions in an IF statement have been met. analysis software ---------------------------------- Analysis software analyzes system performance data. The optional OV Performance Manager product provides a central window from which you can monitor, manage, and troubleshoot the performance of all networked systems in your computing environment, as well as analyze historical data from OV Performance Agent systems. With OV Performance Manager, you can view graphs of a systems' performance data to help you diagnose and resolve performance problems quickly. application ---------------------------------- A user-defined group of related processes or program files. Applications are defined so that performance software can collect performance metrics for and report on the combined activities of the processes and programs. available memory ---------------------------------- Available memory is that part of physical memory not allocated by the kernel. This includes the buffer cache, user allocated memory, and free memory. backtrack ---------------------------------- Backtracking allows the large data structures used by the Virtual Memory Manager (VMM) to be pageable. It is a method of safely allowing the VMM to handle page faults within its own critical sections of code. Examples of backtracking are: * ? A process page faults. * ? The VMM attempts to locate the missing page via its External Page table (XPT). * ? The VMM page faults due to the required XPT itself having been paged out. * ? The VMM safely saves enough information on the stack to restart the process * ? at its first fault. * ? Normal VMM pagein/out routines are used to recover the missing XPT. * ? The required XPT is now present, so the missing page is located and paged-in. * ? The process continues normal execution at the original page fault. bad call ---------------------------------- A failed NFS server call. Calls fail due to lack of system resources (lack of virtual memory) and network errors. biod ---------------------------------- A daemon process responsible for asynchronous block IO on the NFS client. It is used to buffer read-ahead and write-behind IOs. block IO ---------------------------------- Buffered reads and writes. Data is held in the buffer cache, then transferred in fixed-size blocks. Any hardware device that transmits and receives data in blocks is a block-mode device. Compare with character mode. block IO buffer ---------------------------------- A buffer used to store data being transferred to or from a block-mode device through file system input and output, as opposed to character-mode or raw-mode devices. block IO operation ---------------------------------- Any operation being carried out on a block-mode device (such as read, write, or mount). block size ---------------------------------- The size of the primary unit of information used for a file system. It is set when a file system is created. blocked state ---------------------------------- The reason for the last recorded process block. Also called blocked-on state. bottleneck ---------------------------------- A situation that occurs when a system resource is constrained by demand that exceeds its capability. The resource is said to be "bottlenecked." A bottleneck causes system performance to degrade. A primary characteristic of a bottleneck is that it does not occur in all resources at the same time; other resources may instead be underutilized. buffer ---------------------------------- A memory storage area used to temporarily hold code or data until used for input/output operations. buffer cache ---------------------------------- An area of memory that mediates between application programs and disk drives. When a program writes data, it is first placed in the buffer cache, then delivered to the disk at a later time. This allows the disk driver to perform IO operations in batches, minimizing seek time. buffer header ---------------------------------- Entries used by all block IO operations to point to buffers in the file system buffer cache. buffer pool ---------------------------------- See buffer cache. cache ---------------------------------- See buffer cache. cache efficiency ---------------------------------- The extent to which buffered read and read-ahead requests can be satisfied by data already in the cache. cache hit ---------------------------------- Read requests that are satisfied by data already in the buffer cache. See also cache efficiency. character mode ---------------------------------- The mode in which data transfers are accomplished byte-by- byte, rather than in blocks. Printers, plotters, and terminals are examples of character-mode devices. Also known as raw mode. Compare with block IO. child process ---------------------------------- A new process created at another active process' request through a fork or vfork system call. The process making the request becomes the parent process. client ---------------------------------- A system that requests a service from a server. In the context of diskless clusters, a client uses the server's disks and has none of its own. In the context of NFS, a client mounts file systems that physically reside on another system (the Network File System server). clock hand algorithm ---------------------------------- The algorithm used by the page daemon to scan pages. clock hand cycle ---------------------------------- The clock hand algorithm used to control paging and to select pages for removal from system memory. When page faults and/or system demands cause the free list size to fall below a certain level, the page replacement algorithm starts the clock hand and it cycles through the page table. cluster ---------------------------------- One or more work stations linked by a local area network (LAN) but having only one root file system. cluster server process ---------------------------------- (CSPs). A special kernel process that runs in a cluster and handles requests from remote cnodes. coda ---------------------------------- A daemon that provides data to the alarm generator and the OVPM OV Reporter product from all the data sources configured in the datasources configuration file. By default data source for scopeux log file set is defined cnode ---------------------------------- The client on a diskless system. The term cnode is derived from "client node." collision ---------------------------------- Occurs when the system attempts to send a packet at the same time that another system is attempting a send on the same LAN. The result is garbled transmissions and both sides have to resubmit the packet. Some collisions occur during normal operation. context switch ---------------------------------- The action of the dispatcher (scheduler) changing from running one process to another. The scheduler maintains algorithms for managing process switching, mostly directed by process priorities. CPU ---------------------------------- Central Processing Unit. The part of a computer that executes program instructions. CPU entitlement ---------------------------------- The percentage of CPU guaranteed to a particular Process Resource Manager (PRM) group when the total system CPU use is at 100%. The system administrator assigns the CPU entitlement for each PRM group in the PRM configuration file. The minimum entitlement for all groups is 1%. PRM distributes unused time to groups in proportion to their CPU entitlements. CPU queue ---------------------------------- The average number of processes in the "run" state awaiting CPU scheduling, which includes processes short waited for IOs.

A process is accessed in pages (demand paging) during execution. pagedaemon ---------------------------------- A system daemon responsible for writing parts of a process' address space to secondary storage (disk) to support the paging capability of the virtual memory system. page fault ---------------------------------- An event recorded when a process tries to execute code instructions or to reference a data page not resident in a process' mapped physical memory. The system must page-in the missing code or data to allow execution to continue. page freed ---------------------------------- When a paging daemon puts a page in the free list, it is considered as page freed. page in/page out ---------------------------------- Moving pages of data from virtual memory (disk) to physical memory (page in) or vice versa (page out). page reclaim ---------------------------------- Virtual address space is partitioned into segments, which are then partitioned into fixed size units called pages. There are usually two kinds of segments: persistent segments, and working segments. Files containing data or executable programs are mapped into persistent segments. A persistent segment (text) has a permanent storage location on disk so the Virtual Memory Manager writes the page back to that location when the page has been modified and it is no longer kept in real memory. If the page has not changed, its frame is simply reclaimed. page request ---------------------------------- A page fault that has to be satisfied by accessing virtual memory. page scan ---------------------------------- The clock hand algorithm used to control page and to select pages for removal from system memory.

Process Resource Manager (PRM) groups are defined in the PRM configuration file /etc/prmconf or a configuration file you specify. Each PRM group has a name, a number (PRMID), and a CPU entitlement. Groups can optionally have memory entitlements and disk bandwidth entitlements. PRMID ---------------------------------- An integer between 0 and 47, inclusive, that uniquely identifies a Process Resource Manager (PRM) group in the PRM configuration file. PRMID 0 is reserved for the System Group. PRMID 1 is reserved for the User Default Group. proc table ---------------------------------- The process table that holds information for every process on the system. process ---------------------------------- The execution of a program file. This execution can represent an interactive user (processes running at normal, nice, or real-time priorities) or an operating system process. process block ---------------------------------- A process block occurs when a process is not executing because it is waiting for a resource or IO completion. process deactivation/reactivation ---------------------------------- A technique used for memory management.

It specifies what the users can expect in terms of system response, quantities of work, and system availability. service level objective ---------------------------------- A definable level of responsiveness for a transaction. For example, if you decide that all database updates must occur within 2 seconds, set the Service Level Objective (SLO) for that transaction as slo=2. shared memory ---------------------------------- System memory allocated for sharing data among processes. It includes shared text, data and stack. shared memory pool ---------------------------------- The cache in which shared memory segments are stored. shared memory segment ---------------------------------- A portion of a system's memory dedicated to sharing data for several processes. shared memory table ---------------------------------- A list of entries that identifies shared memory segments currently allocated on your system. shared text segment ---------------------------------- Code shared between several processes. signal ---------------------------------- A software event to notify a process of a change.

Summary levels can be five minutes, one hour, and one day. swap ---------------------------------- A memory management technique used to shuttle information between the main memory and a dedicated area on a disk (swap space). Swapping allows the system to run more processes than could otherwise fit into the main memory at a given time. swap in/out ---------------------------------- Moving information between the main memory and a dedicated (reserved) area on a disk. ''Swapping in'' is reading in to virtual memory; ''swapping out'' is reading out from virtual memory. swap space ---------------------------------- The area of a disk or memory reserved for swapping out entire processes or paging out portions of processes. Also known as page space. system call ---------------------------------- A command that a program uses to tell the kernel to perform a specific service on the program's behalf. This is the user's and application programmer's interface to the UNIX kernel. system code ---------------------------------- Kernel code that is executed through system calls. system CPU ---------------------------------- Time that the CPU was busy executing kernel code. Also called kernel mode. system disk ---------------------------------- Physical disk IO generated for file system management. These include inode access, super block access and cylinder group access. system group ---------------------------------- The PRM group with PRMID 0. PRM places all system processes, such as init and swapper, in this group by default. system interrupt handling code ---------------------------------- Kernel code that processes interrupts. terminal transaction ---------------------------------- A terminal transaction occurs whenever a read is completed to a terminal device or MPE message file. On a terminal device, a read is normally completed when the user presses the return or the enter key. Some devices such as serial printers may satisfy terminal reads by returning hardware status information. Several metrics are collected to characterize terminal transactions. The FIRST_RESPONSE_TIME metric measures the time between the completion of the read and the completion of the first write back to that device. This metric is most often quoted in bench marks as it yields the quickest response time. For transactions which return a large amount of data to the terminal, such as reading an electronic mail message, the time to first response may be the best indicator of overall system responsiveness. The RESPONSE_TIME_TO_PROMPT metric measures the time between the completion of the read and the posting of the next read. It is the amount of time that a user must wait before being able to enter the next transaction. This response time includes the amount of time it took to write data back to the terminal as a result of the transaction. The response time to prompt is the best metric for determining the limits of transaction throughput. The THINK_TIME metric measures the time between posting a read and its completion. It is a measure of how much time the user took to examine the results of the transaction and then complete entering the next transaction. Transaction metrics are expressed as average times per transaction and as total times in seconds. Total times are calculated by multiplying the average time per transaction times the number of transactions completed. Terminal transactions can be created by interactive or batch processes that do reads to terminal devices or message files. Reads to terminal devices or message files done by system processes will not be counted as transactions. text segment ---------------------------------- A memory segment that holds executable program code. thrashing ---------------------------------- A condition in which a system is spending too much time swapping data in and out, and too little time doing useful work. This is characteristic of situations in which either too many page faults are being created or too much swapping is occurring. Thrashing causes the system's performance to degrade and the response time for the interactive users to increase. threadpool queue ---------------------------------- A queue of requests waiting for an available server thread. threshold ---------------------------------- Numerical values that can be set to define alarm conditions. When a threshold is surpassed, an alarm is triggered. tooltip ---------------------------------- Display of the full text of a truncated data string in a row- column formated GlancePlus report window.

The boundaries of this work are defined by the user. transaction tracking ---------------------------------- The technology used by OV Performance Agent and GlancePlus that lets information technology (IT) managers measure end- to-end response time of business application transactions. trap ---------------------------------- Software interrupt that requires service from a trap handler routine. An example would be a floating point exception on a system that does not have floating point hardware support. This requires the floating point operations to be emulated in the software trap handler code. trap handler code ---------------------------------- Traps are measured when the kernel executes the code in the trap handler routine. For a list of trap types, refer to the file /usr/include/machine/trap.h. ttd.conf ---------------------------------- The transaction tracking configuration file where you define each transaction and the information to be tracked for each transaction, such as transaction name, performance distribution range, and service level objective. unmount/mount ---------------------------------- The process of removing or adding functionally-independent file systems from or to the root file system. update interval ---------------------------------- The interval of time between updates of the metrics that display in a report window or graph. user code ---------------------------------- Code that does not perform system calls. user CPU ---------------------------------- Time that the CPU was busy executing user code. This includes time spent executing non-kernel code by daemon processes. It does not include CPU time spent executing system calls, context switching, or interrupt handling. user default group ---------------------------------- The PRM group with PRMID 1. PRM uses this group as the initial group for any user who does not have a PRM user record in the currently loaded PRM configuration file. user disk ---------------------------------- Physical disk IO generated by accessing the file system. utility program ---------------------------------- AN OV Performance Server Agent program that lets you check parm file and alarmdef file syntax, resize log files, scan log files for information, and obtain alarm information from historical log file data. vfault CPU ---------------------------------- CPU time spent handling page faults. vfaults ---------------------------------- A vfault (virtual fault) is the mechanism that causes paging. Accessing an unmapped valid page causes a resolvable vfault. Accessing an illegal address results in a SIGSEGV. vfork ---------------------------------- A version of the fork system call that spawns a child process that is capable of sharing code and data with its parent process. virtual memory ---------------------------------- Secondary memory that exists on a portion of a disk or other storage device. It is used as an extension of the primary physical memory. virtual memory IO ---------------------------------- The virtual memory reads or writes from the disk for memory mapped files, and for paging out pages from paging area (swap area). Since all the files are memory mapped, all the reads or writes are virtual memory reads or writes as well. The computational memory of the processes that are changing is paged out if necessary to the swap area and read or written from there again. write byte rate ---------------------------------- The rate of kilobytes per second the system sent or received during write operations. write rate ---------------------------------- The number of NFS and local write operations the local machine has processed per second. Write operations include setattr, writecache, create, remove, rename, link, symlink, mkdir, rmdir, and write. X-Axis ---------------------------------- The horizontal scale on a graph. Y-Axis ---------------------------------- The vertical scale on a graph. zero fill page ---------------------------------- When pages are requested by the processes they are usually allocated by the Virtual Memory Management system and filled with zeros. HP-UX Run Queue Example ---------------------------------- For example, let's assume we're using a system with eight processors. We start eight CPU intensive processes that consume almost all of the CPU resources. The approximate values shown for the CPU related queue metrics would be: GBL_RUN_QUEUE = 1.0 GBL_PRI_QUEUE = 0.1 GBL_CPU_QUEUE = 1.0 Assume we start an additional eight CPU intensive processes. The approximate values now shown are: GBL_RUN_QUEUE = 2.0 GBL_PRI_QUEUE = 8.0 GBL_CPU_QUEUE = 9.0 At this point, we have sixteen CPU intensive processes running on the eight processors. Keeping the definitions of the three queue metrics in mind, the run queue is 2 (that is, 16 / 8); the pri queue is 8 (only half of the processes can be active at any given time); and the cpu queue is 9 (half of the processes waiting in the cpu queue that are ready to run, plus one for the active process). This illustrates that the run queue is the average of the 1- minute load averages for all processors; the pri queue is the number of processes or kernel threads that are blocked on "PRI" (priority); and the cpu queue is the number of processes or kernel threads in the cpu queue that are ready to run, including the processes or kernel threads using the CPU. AIX SPLPAR ---------------------------------- Using Micro-Partitioning technology, physical processors are divided into virtual processors that are shared in a pool between one or more LPARs. An LPAR that can use processors from shared pool is called as Shared Processor LPAR or Micro- Partition. recognized VMWare ESX guest ---------------------------------- A logical system, hosted on VMWare ESX Server, and VMWare tools is installed. VMWare ESX Server console ---------------------------------- refers to the services console of VMWare ESX Server logical system ---------------------------------- refers to a LPAR or a virtual machine hosted as a guest on HPVM or ESX Server. virtual environment ---------------------------------- refers to a logical system, VMWare ESX Server Console and HP- UX system hosting HPVM. AIX LPAR ---------------------------------- A subset of logical resources that are capable of supporting an operating system. A logical partition consists of CPUs, memory, and I/O slots that are a subset of the pool of available resources within a system. virtual CPUs ---------------------------------- number of CPUs allocated to a Logical System virtual machines ---------------------------------- An empty, isolated, virtual environment, lying on top of a host OS, equipped with virtual hardware (processor, memory, disks, network interfaces, etc.) and managed by a virtualization product. It's where the guest OS is installed HP-UX host ---------------------------------- The system where HPVM is installed.
