APP_ACTIVE_APP
----------------------------------
The number of applications that had processes active (consuming cpu
resources) 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 -----------

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_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. On
platforms other than HPUX, If the ignore_mt flag is set(true) in parm file,
this metric will report values normalized against the number of active cores
in the system.
If the ignore_mt flag is not set(false) in parm file, this metric will report
values normalized against the number of threads in the system. This flag will
be a no-op if Multithreading is turned off.
On HPUX, CPU utilization normalization is controlled by the “-ignore_mt”
option of the midaemon(1m). To change normalization from core-based to
logical-cpu-based, or vice-versa, all performance components (scopeux,
glance, perfd) must be shut down and the midaemon restarted in the desired
mode. To start the midaemon with “-ignore_mt” by default, this option should
be added in the /etc/rc.config.d/ovpa control file. Refer to the
documentation regarding ovpa startup. Note that, on HPUX, unlike other
platforms, specifying core-based normalization affects CPU, application,
process and thread metrics.
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. On platforms other than HPUX, If the ignore_mt flag
is set(true) in parm file, this metric will report values normalized against
the number of active cores in the system.
If the ignore_mt flag is not set(false) in parm file, this metric will report
values normalized against the number of threads in the system. This flag will
be a no-op if Multithreading is turned off.
On HPUX, CPU utilization normalization is controlled by the “-ignore_mt”
option of the midaemon(1m). To change normalization from core-based to
logical-cpu-based, or vice-versa, all performance components (scopeux,

be added in the /etc/rc.config.d/ovpa control file. Refer to the
documentation regarding ovpa startup. Note that, on HPUX, unlike other
platforms, specifying core-based normalization affects CPU, application,
process and thread metrics.
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. On
platforms other than HPUX, If the ignore_mt flag is set(true) in parm file,
this metric will report values normalized against the number of active cores
in the system.
If the ignore_mt flag is not set(false) in parm file, this metric will report
values normalized against the number of threads in the system. This flag will
be a no-op if Multithreading is turned off.
On HPUX, CPU utilization normalization is controlled by the “-ignore_mt”
option of the midaemon(1m). To change normalization from core-based to
logical-cpu-based, or vice-versa, all performance components (scopeux,
glance, perfd) must be shut down and the midaemon restarted in the desired
mode. To start the midaemon with “-ignore_mt” by default, this option should
be added in the /etc/rc.config.d/ovpa control file. Refer to the
documentation regarding ovpa startup. Note that, on HPUX, unlike other
platforms, specifying core-based normalization affects CPU, application,
process and thread metrics.
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. On platforms other than HPUX, If the ignore_mt flag is set(true) in
parm file, this metric will report values normalized against the number of
active cores in the system.
If the ignore_mt flag is not set(false) in parm file, this metric will report
values normalized against the number of threads in the system. This flag will
be a no-op if Multithreading is turned off.
On HPUX, CPU utilization normalization is controlled by the “-ignore_mt”

be added in the /etc/rc.config.d/ovpa control file. Refer to the
documentation regarding ovpa startup. Note that, on HPUX, unlike other
platforms, specifying core-based normalization affects CPU, application,
process and thread metrics.
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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this. On platforms other than HPUX, If
the ignore_mt flag is set(true) in parm file, this metric will report values
normalized against the number of active cores in the system.
If the ignore_mt flag is not set(false) in parm file, this metric will report
values normalized against the number of threads in the system. This flag will
be a no-op if Multithreading is turned off.
On HPUX, CPU utilization normalization is controlled by the “-ignore_mt”
option of the midaemon(1m). To change normalization from core-based to

be added in the /etc/rc.config.d/ovpa control file. Refer to the
documentation regarding ovpa startup. Note that, on HPUX, unlike other
platforms, specifying core-based normalization affects CPU, application,
process and thread metrics.
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. On
platforms other than HPUX, If the ignore_mt flag is set(true) in parm file,
this metric will report values normalized against the number of active cores
in the system.
If the ignore_mt flag is not set(false) in parm file, this metric will report
values normalized against the number of threads in the system. This flag will
be a no-op if Multithreading is turned off.
On HPUX, CPU utilization normalization is controlled by the “-ignore_mt”
option of the midaemon(1m). To change normalization from core-based to
logical-cpu-based, or vice-versa, all performance components (scopeux,

mode. To start the midaemon with “-ignore_mt” by default, this option should
be added in the /etc/rc.config.d/ovpa control file. Refer to the
documentation regarding ovpa startup. Note that, on HPUX, unlike other
platforms, specifying core-based normalization affects CPU, application,
process and thread metrics.
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. On
platforms other than HPUX, If the ignore_mt flag is set(true) in parm file,
this metric will report values normalized against the number of active cores
in the system.
If the ignore_mt flag is not set(false) in parm file, this metric will report
values normalized against the number of threads in the system. This flag will
be a no-op if Multithreading is turned off.

documentation regarding ovpa startup. Note that, on HPUX, unlike other
platforms, specifying core-based normalization affects CPU, application,
process and thread metrics.
APP_DISK_BLOCK_IO
----------------------------------
The number of block IOs to the file system buffer cache for processes in this
group during the interval.
On Sun 5.X (Solaris 2.X or later), these are physical IOs generated by file
system access and do not include virtual memory IOs, or IOs relating to raw
disk access. These are IOs for inode and superblock updates which are
handled through the buffer cache. Because virtual memory IOs are not
credited to the process, the block IOs tend to be much lower on SunOS 5.X
than they are on SunOS 4.1.X systems.
When a file is accessed on SunOS 5.X or later, 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 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.
Note, when a file is accessed on AIX, it is memory mapped by the operating
system, so accesses generate virtual memory IOs, not block IOs.
APP_DISK_BLOCK_IO_RATE
----------------------------------
The number of block IOs per second to the file system buffer cache for
processes in this group during the interval.

APP_DISK_BLOCK_READ
----------------------------------
The number of block reads from the file system buffer cache for processes in
this group during the interval.
On Sun 5.X (Solaris 2.X or later), these are physical reads generated by file
system access and do not include virtual memory IOs, or IOs relating to raw
disk access. These are IOs for inode and superblock updates which are

APP_DISK_BLOCK_WRITE
----------------------------------
The number of block writes to the file system buffer cache for processes in
this group during the interval.

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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up

after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
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_LS_ID
----------------------------------
APP_LS_ID represents the zone-id of the zone associated with this
application.
This metric is only available on Solaris 10 and above versions when the
zone_app flag in parm file is set.
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_RES
----------------------------------
On Unix systems, this is the sum of the size (in MB) 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 MB) 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.
APP_MEM_VIRT
----------------------------------
On Unix systems, this is the sum (in MB) 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 MB) 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_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_NUM
----------------------------------
The sequentially assigned number of this application or, on Solaris, the
project ID when application grouping by project is enabled.
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_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_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_REVERSE_PRI
----------------------------------
The average priority of the processes in this group during the interval.
Lower values for this metric always imply higher processing priority. The
range is from 0 to 127. Since priority ranges can be customized on this OS,
this metric provides a standardized way of interpreting priority that is
consistent with other versions of Unix. See also the APP_PRI metric.
This is derived from the PRI field of the ps command when the -c option is
not used.
APP_REV_PRI_STD_DEV
----------------------------------
The standard deviation of priorities of the processes in this group during
the interval. Priorities are mapped into a traditional lower value implies
higher priority scheme.
APP_SAMPLE
----------------------------------
The number of samples of process data that have been averaged or accumulated
during this sample.
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.
The Linux kernel currently doesn’t provide any metadata information for
disabled CPUs. This means that there is no way to find out types, speeds, as
well as hardware IDs or any other information that is used to determine the
number of cores, the number of threads, the HyperThreading state, etc... If
the agent (or Glance) is started while some of the CPUs are disabled, some of
these metrics will be “na”, some will be based on what is visible at startup
time. All information will be updated if/when additional CPUs are enabled and
information about them becomes available. The configuration counts will
remain at the highest discovered level (i.e. if CPUs are then disabled, the
maximum number of CPUs/cores/etc... will remain at the highest observed
level). It is recommended that the agent be started with all CPUs enabled.
On Linux, this value is always rounded up to the next MHz.
BYCPU_CPU_SYSCALL_TIME
----------------------------------
The time, in seconds, that this CPU was running in system mode (not including
interrupt, context switch, trap or vfault CPU) during the last interval. On
platforms other than HPUX, If the ignore_mt flag is set(true) in parm file,
this metric will report values normalized against the number of active cores
in the system.
If the ignore_mt flag is not set(false) in parm file, this metric will report
values normalized against the number of threads in the system. This flag will
be a no-op if Multithreading is turned off.
On HPUX, CPU utilization normalization is controlled by the “-ignore_mt”
option of the midaemon(1m). To change normalization from core-based to
logical-cpu-based, or vice-versa, all performance components (scopeux,
glance, perfd) must be shut down and the midaemon restarted in the desired
mode. To start the midaemon with “-ignore_mt” by default, this option should
be added in the /etc/rc.config.d/ovpa control file. Refer to the
documentation regarding ovpa startup. Note that, on HPUX, unlike other
platforms, specifying core-based normalization affects CPU, application,
process and thread metrics.
BYCPU_CPU_SYSCALL_TIME_CUM
----------------------------------
The time, in seconds, that this CPU was running in system mode (not including
interrupt, context switch, trap or vfault CPU) over the cumulative collection
time.
The cumulative collection time is defined from the point in time when
either: a) the process (or thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this. On platforms other than HPUX, If
the ignore_mt flag is set(true) in parm file, this metric will report values
normalized against the number of active cores in the system.
If the ignore_mt flag is not set(false) in parm file, this metric will report
values normalized against the number of threads in the system. This flag will
be a no-op if Multithreading is turned off.

BYCPU_CPU_SYS_MODE_TIME
----------------------------------
The time, in seconds, that this CPU (or logical processor) was in system mode
during the interval.
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 platforms other than
HPUX, If the ignore_mt flag is set(true) in parm file, this metric will
report values normalized against the number of active cores in the system.

at a normal priority, at real-time priority (on HP-UX, AIX, and Windows
systems), and at a nice priority.
The cumulative collection time is defined from the point in time when
either: a) the process (or thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this. On platforms other than HPUX, If
the ignore_mt flag is set(true) in parm file, this metric will report values
normalized against the number of active cores in the system.
If the ignore_mt flag is not set(false) in parm file, this metric will report
values normalized against the number of threads in the system. This flag will
be a no-op if Multithreading is turned off.
On HPUX, CPU utilization normalization is controlled by the “-ignore_mt”
option of the midaemon(1m). To change normalization from core-based to
logical-cpu-based, or vice-versa, all performance components (scopeux,
glance, perfd) must be shut down and the midaemon restarted in the desired
mode. To start the midaemon with “-ignore_mt” by default, this option should
be added in the /etc/rc.config.d/ovpa control file. Refer to the
documentation regarding ovpa startup. Note that, on HPUX, unlike other
platforms, specifying core-based normalization affects CPU, application,
process and thread metrics.
BYCPU_CPU_USER_MODE_UTIL
----------------------------------
The percentage of time that this CPU (or logical processor) was in user mode
during the interval.
User CPU is the time spent in user mode at a normal priority, at real-time

platforms other than HPUX, If the ignore_mt flag is set(true) in parm file,
this metric will report values normalized against the number of active cores
in the system.

“Offline”, “Online” or “Unknown”.
BYDSK_AVG_REQUEST_QUEUE
----------------------------------
The average number of IO requests that were in the wait and service queues
for this disk device over the cumulative collection time.
The cumulative collection time is defined from the point in time when
either: a) the process (or thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up

For example, if 4 intervals have passed with average queue lengths of 0, 2,
0, and 6, then the average number of IO requests over all intervals would be
2.
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.
BYDSK_AVG_SERVICE_TIME
----------------------------------
The average time, in milliseconds, that this disk device spent processing
each disk request during the interval. For example, a value of 5.14 would
indicate that disk requests during the last interval took on average slightly
longer than five one-thousandths of a second to complete for this device.
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.
This is a measure of the speed of the disk, because slower disk devices
typically show a larger average service time. Average service time is also
dependent on factors such as the distribution of I/O requests over the
interval and their locality. It can also be influenced by disk driver and
controller features such as I/O merging and command queueing. Note that this
service time is measured from the perspective of the kernel, not the disk
device itself. For example, if a disk device can find the requested data in
its cache, the average service time could be quicker than the speed of the
physical disk hardware.
This metric can be used to help determine which disk devices are taking more
time than usual to process requests.
BYDSK_BUSY_TIME

The time, in seconds, that this disk device was busy transferring data during
the interval.
On HP-UX, this is the time, in seconds, during the interval that the disk

other words, the time, in seconds, the disk was busy servicing requests for
this device.

----------------------------------
The average number of physical IO requests that were in the wait and service
queues for this disk device during the interval.

present on these systems. Distributions and OS releases that are known to be
affected include: TurboLinux 7, SuSE 7.2, and Debian 3.0.
BYDSK_DEVNAME
----------------------------------
The name of this disk device.
On HP-UX, the name identifying the specific disk spindle is the hardware path
which specifies the address of the hardware components leading to the disk
device.
On SUN, these names are the same disk names displayed by “iostat”.
On AIX, this is the path name string of this disk device. This is the fsname
parameter in the mount(1M) command. If more than one file system is
contained on a device (that is, the device is partitioned), this is indicated
by an asterisk (“*”) at the end of the path name.
On OSF1, this is the path name string of this disk device. This is the file-
system parameter in the mount(1M) command.

after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
For example if 4 intervals have passed (that is, 4 screen updates) and the
average queue length for these intervals was 0, 1.5, 0, and 3, then the value
for this metric would be 50% since 50% of the intervals had a zero queue
length.
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.
BYDSK_QUEUE_2_UTIL
----------------------------------
The percentage of intervals during which there were 1 or 2 IO requests
pending for this disk device over the cumulative collection time.
The cumulative collection time is defined from the point in time when
either: a) the process (or thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
For example if 4 intervals have passed (that is, 4 screen updates) and the
average queue length for these intervals was 0, 1, 0, and 2, then the value
for this metric would be 50% since 50% of the intervals had a 1-2 queue
length.
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.
BYDSK_QUEUE_4_UTIL
----------------------------------
The percentage of intervals during which there were 3 or 4 IO requests
waiting to use this disk device over the cumulative collection time.
The cumulative collection time is defined from the point in time when
either: a) the process (or thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
For example if 4 intervals have passed (that is, 4 screen updates) and the
average queue length for these intervals was 0, 3, 0, and 4, then the value
for this metric would be 50% since 50% of the intervals had a 3-4 queue
length.
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.
BYDSK_QUEUE_8_UTIL
----------------------------------
The percentage of intervals during which there were between 5 and 8 IO
requests pending for this disk device over the cumulative collection time.
The cumulative collection time is defined from the point in time when
either: a) the process (or thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
For example if 4 intervals have passed (that is, 4 screen updates) and the
average queue length for these intervals was 0, 8, 0, and 5, then the value
for this metric would be 50% since 50% of the intervals had a 5-8 queue
length.
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.

----------------------------------
The percentage of intervals during which there were more than 8 IO requests
pending for this disk device over the cumulative collection time.
The cumulative collection time is defined from the point in time when
either: a) the process (or thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
For example if 4 intervals have passed (that is, 4 screen updates) and the
average queue length for these intervals was 0, 9, 0, and 10, then the value
for this metric would be 50% since 50% of the intervals had queue length
greater than 8.
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.
BYDSK_REQUEST_QUEUE
----------------------------------
The average number of IO requests that were in the wait queue for this disk
device during the interval. These requests are the physical requests (as
opposed to logical IO requests).
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.
BYDSK_TIME

BYDSK_UTIL
----------------------------------
On HP-UX, this is the percentage of the time during the interval that the
disk device had IO in progress from the point of view of the Operating
System. In other words, the utilization or percentage of time busy servicing
requests for this device.
On the non-HP-UX systems, this is the percentage of the time that this disk
device was busy transferring data during the interval.
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.
This is a measure of the ability of the IO path to meet the transfer demands
being placed on it. Slower disk devices may show a higher utilization with
lower IO rates than faster disk devices such as disk arrays. A value of
greater than 50% utilization over time may indicate that this device or its
IO path is a bottleneck, and the access pattern of the workload, database, or
files may need reorganizing for better balance of disk IO load.
BYDSK_UTIL_CUM
----------------------------------
On HP-UX, this is the percentage of the time that this disk device had IO in
progress from the point of view of the Operating System over the cumulative
collection time. In other words, this is the utilization or percentage of
time busy servicing requests for this device.
On all other Unix systems, this is the percentage of the time that this disk
device was busy transferring data over the cumulative collection time.
The cumulative collection time is defined from the point in time when
either: a) the process (or thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
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

lower IO rates than faster disk devices such as disk arrays. A value of
greater than 50% utilization over time may indicate that this device or its
IO path is a bottleneck, and the access pattern of the workload, database, or
files may need reorganizing for better balance of disk IO load.

For WPARs, this metric represents how much of a particular resource a WPAR
receives relative to the other WPARs.
On vMA, for logical system and resource pool this value can range from 1 to

BYLS_MEM_ENTL_MIN)
BYLS_NUM_CPU
----------------------------------

On AIX LPARs, this metric will be “na”.
On vMA, for a host and logical system the metric is the uptime in seconds
while for a resource pool the metric is NA.
BYNETIF_COLLISION
----------------------------------
The number of physical collisions that occurred 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.
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).
If BYNETIF_NET_TYPE is “ESXVLan”, then this metric will be N/A.
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.
On AIX System WPARs, this metric value is identical to the value on AIX
Global Environment.
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.
This data is not collected for non-broadcasting devices, such as loopback
(lo), and is always zero.
If BYNETIF_NET_TYPE is “ESXVLan”, then this metric will be N/A.
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

BYNETIF_COLLISION_RATE_CUM
----------------------------------
The average number of physical collisions per second on the network interface
over the cumulative collection time. 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.
The cumulative collection time is defined from the point in time when
either: a) the process (or thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
This data is not collected for non-broadcasting devices, such as loopback
(lo), and is always zero.

always zero.
This metric is updated at the sampling interval, regardless of the number of
IP addresses on the system.
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.
For HP-UX, this will be the same as the sum of the “Inbound Errors” and
“Outbound Errors” 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 “Ierrs” (RX-ERR on
Linux) and “Oerrs” (TX-ERR on Linux) from the “netstat -i” command for a
network device. See also netstat(1).
If BYNETIF_NET_TYPE is “ESXVLan”, then this metric will be N/A.

On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
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_PACKET_RATE
----------------------------------
The number of successful physical packets per second sent and received
through the network interface during the interval. Successful packets are
those that have been processed without errors or collisions.
If BYNETIF_NET_TYPE is “ESXVLan”, then this metric shows the values for the
Lan card in the host.
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.

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.
BYOP_CLIENT_COUNT
----------------------------------
The number of current NFS operations that the local machine has processed as
a NFS client during the interval.
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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
BYOP_CLIENT_COUNT_CUM
----------------------------------
The number of current NFS operations that the local machine has processed as
a NFS client 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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.

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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
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 device can be logical volume, “lv” or remote file system,
“remote fs”. The swap is often referred as paging to paging space.
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.
The scope collector logs the value of this metric in decimal format.
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 Perf Agent).
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_FRAG_SIZE
----------------------------------
The fundamental file system block size, 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_INODE_UTIL
----------------------------------
Percentage of this file system’s inodes in use during the interval.
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_MAX_INODES
----------------------------------
Number of configured file system inodes.
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_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_RESERVED
----------------------------------
The amount of file system space in MBs reserved for superuser allocation.
On AIX, this metric is typically zero for local filesystems because by
default AIX does not reserve any file system space for the superuser.
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.
On HP-UX, this metric is updated at 4 minute intervals to minimize collection
overhead.
FS_TYPE
----------------------------------
A string indicating the file system type. On Unix systems, some of the
possible types are:
hfs - user file system
ufs - user file system
ext2 - user file system
cdfs - CD-ROM file system
vxfs - Veritas (vxfs) file system
nfs - network file system
nfs3 - network file system
Version 3
On Windows, some of the possible types are:
NTFS - New Technology File System
FAT - 16-bit File Allocation
Table
FAT32 - 32-bit File Allocation
Table
FAT uses a 16-bit file allocation table entry (216 clusters).
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. NTFS is native file system
of Windows NT and beyond.
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.
On AIX System WPARs, this metric value is identical to the value on AIX
Global Environment if RSET is not configured for the System WPAR. If RSET is
configured for the System WPAR, this metric value will report the number of
CPUs in the RSET.
On Solaris non-global zones with Uncapped CPUs, this metric shows data from
the global zone.
GBL_ACTIVE_CPU_CORE
----------------------------------
This metric provides the total number of active CPU cores on a physical
system.
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_BLOCKED_IO_QUEUE
----------------------------------
The average number of processes blocked on local disk resources (IO, paging).
This metric is an indicator of disk contention among active processes. It
should normally be a very small number. If GBL_DISK_UTIL_PEAK is near 100
percent and GBL_BLOCKED_IO_QUEUE is greater than 1, a disk bottleneck is
probable.
On SUN, this is the same as the “procs b” field reported in vmstat.
On Solaris non-global zones, this metric shows data from the global zone.
GBL_BOOT_TIME
----------------------------------
The date and time when the system was last booted.
GBL_COLLECTION_MODE
----------------------------------
This metric reports whether the data collection is running as “root” (super-
user) or “non-root” (regular user). Running as non-root results in a loss of
functionality which varies across Unix platforms. Running non-root is not
available on HP-UX.
The value is always “admin” on Windows.
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.
GBL_CPU_CLOCK
----------------------------------
The clock speed of the CPUs in MHz if all of the processors have the same
clock speed. Otherwise, “na” is shown if the processors have different clock
speeds. Note that Linux supports dynamic frequency scaling and if it is
enabled then there can be a change in CPU speed with varying load.
GBL_CPU_IDLE_TIME
----------------------------------
The time, in seconds, that the CPU was idle during the interval. This is the
total idle time, including waiting for I/O (and stolen time on Linux).
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.
On AIX System WPARs, this metric value is calculated against physical cpu
time.
On Solaris non-global zones, this metric is N/A. On platforms other than
HPUX, If the ignore_mt flag is set(true) in parm file, this metric will
report values normalized against the number of active cores in the system.
If the ignore_mt flag is not set(false) in parm file, this metric will report
values normalized against the number of threads in the system. This flag will
be a no-op if Multithreading is turned off.
On HPUX, CPU utilization normalization is controlled by the “-ignore_mt”
option of the midaemon(1m). To change normalization from core-based to
logical-cpu-based, or vice-versa, all performance components (scopeux,
glance, perfd) must be shut down and the midaemon restarted in the desired
mode. To start the midaemon with “-ignore_mt” by default, this option should
be added in the /etc/rc.config.d/ovpa control file. Refer to the
documentation regarding ovpa startup. Note that, on HPUX, unlike other
platforms, specifying core-based normalization affects CPU, application,
process and thread metrics.
GBL_CPU_IDLE_TIME_CUM
----------------------------------
The time, in seconds, that the CPU was idle over the cumulative collection
time. This is the total idle time, including waiting for I/O (and stolen
time on Linux).
The cumulative collection time is defined from the point in time when
either: a) the process (or thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
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.
On platforms other than HPUX, If the ignore_mt flag is set(true) in parm
file, this metric will report values normalized against the number of active
cores in the system.
If the ignore_mt flag is not set(false) in parm file, this metric will report
values normalized against the number of threads in the system. This flag will
be a no-op if Multithreading is turned off.
On HPUX, CPU utilization normalization is controlled by the “-ignore_mt”
option of the midaemon(1m). To change normalization from core-based to
logical-cpu-based, or vice-versa, all performance components (scopeux,
glance, perfd) must be shut down and the midaemon restarted in the desired
mode. To start the midaemon with “-ignore_mt” by default, this option should
be added in the /etc/rc.config.d/ovpa control file. Refer to the
documentation regarding ovpa startup. Note that, on HPUX, unlike other
platforms, specifying core-based normalization affects CPU, application,
process and thread metrics.
GBL_CPU_IDLE_UTIL
----------------------------------
The percentage of time that the CPU was idle during the interval. This is
the total idle time, including waiting for I/O (and stolen time on Linux).
On Unix systems, this is the same as the sum of the “%idle” and “%wio” fields
reported by the “sar -u” command.
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.
On Solaris non-global zones, this metric is N/A. On platforms other than
HPUX, If the ignore_mt flag is set(true) in parm file, this metric will
report values normalized against the number of active cores in the system.
If the ignore_mt flag is not set(false) in parm file, this metric will report
values normalized against the number of threads in the system. This flag will
be a no-op if Multithreading is turned off.
On HPUX, CPU utilization normalization is controlled by the “-ignore_mt”
option of the midaemon(1m). To change normalization from core-based to
logical-cpu-based, or vice-versa, all performance components (scopeux,
glance, perfd) must be shut down and the midaemon restarted in the desired
mode. To start the midaemon with “-ignore_mt” by default, this option should
be added in the /etc/rc.config.d/ovpa control file. Refer to the
documentation regarding ovpa startup. Note that, on HPUX, unlike other
platforms, specifying core-based normalization affects CPU, application,
process and thread metrics.
GBL_CPU_IDLE_UTIL_CUM
----------------------------------
The percentage of time that the CPU was idle over the cumulative collection
time. This is the total idle time, including waiting for I/O (and stolen
time on Linux).
The cumulative collection time is defined from the point in time when
either: a) the process (or thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
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. On
platforms other than HPUX, If the ignore_mt flag is set(true) in parm file,
this metric will report values normalized against the number of active cores
in the system.
If the ignore_mt flag is not set(false) in parm file, this metric will report
values normalized against the number of threads in the system. This flag will
be a no-op if Multithreading is turned off.

----------------------------------
On AIX, this metric indicates if this (Logical) System has SMT enabled or
not.
Other platforms, this metric shows either HyperThreading(HT) is Enabled or
Disabled/Not Supported.
On Linux, this state is dynamic: if HyperThreading is enabled but all the
CPUs have only one logical processor enabled, this metric will report that HT
is disabled.
On AIX System WPARs, this metric is NA.
On Windows, this metric will be “na” on Windows Server 2003 Itanium systems.

High system mode CPU percentages are normal for IO intensive applications.
Abnormally high system mode CPU percentages can indicate that a hardware

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_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 a
logical system, this metric indicates the logical utilization with respect to
number of processors available for the logical system (GBL_NUM_CPU).
On platforms other than HPUX, If the ignore_mt flag is set(true) in parm
file, this metric will report values normalized against the number of active
cores in the system.
If the ignore_mt flag is not set(false) in parm file, this metric will report
values normalized against the number of threads in the system. This flag will
be a no-op if Multithreading is turned off.
On HPUX, CPU utilization normalization is controlled by the “-ignore_mt”
option of the midaemon(1m). To change normalization from core-based to
logical-cpu-based, or vice-versa, all performance components (scopeux,
glance, perfd) must be shut down and the midaemon restarted in the desired
mode. To start the midaemon with “-ignore_mt” by default, this option should
be added in the /etc/rc.config.d/ovpa control file. Refer to the
documentation regarding ovpa startup. Note that, on HPUX, unlike other
platforms, specifying core-based normalization affects CPU, application,
process and thread metrics.
GBL_CPU_TOTAL_UTIL_CUM
----------------------------------
The percentage of total CPU time that the processor was not idle over the
cumulative collection time.
The cumulative collection time is defined from the point in time when
either: a) the process (or thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
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. On
platforms other than HPUX, If the ignore_mt flag is set(true) in parm file,
this metric will report values normalized against the number of active cores
in the system.
If the ignore_mt flag is not set(false) in parm file, this metric will report

----------------------------------
The average number of context switches per second 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.
On Windows, this includes switches from one thread to another either inside a
single process or across processes. A thread switch can be caused either by
one thread asking another for information or by a thread being preempted by
another higher priority thread becoming ready to run.
On Solaris non-global zones with Uncapped CPUs, this metric shows data from
the global zone.
GBL_CSWITCH_RATE_CUM
----------------------------------
The average number of context switches per second over the cumulative
collection time.
The cumulative collection time is defined from the point in time when
either: a) the process (or thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred

GBL_DISK_BLOCK_IO
----------------------------------
The total number of block IOs during the interval.
On SUN, these are physical IOs generated by file system access and do not
include virtual memory IOs, or IOs relating to raw disk access. These are
IOs for inode and superblock updates which are handled through the buffer
cache. Because virtual memory IOs are not credited to the process, the block
IOs tend to be much lower on SunOS 5.X than they are on SunOS 4.1.X systems.
When a file is accessed on SunOS 5.X or later, 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 AIX, these are physical IOs generated by file system access and do not
include virtual memory IOs, or IOs relating to raw disk access. These do
include the IO of the inode (system write) and the file system data IO.
On Solaris non-global zones with Uncapped CPUs, this metric shows data from
the global zone.
GBL_DISK_BLOCK_IO_CUM

On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after

include the IO of the inode (system write) and the file system data IO.
GBL_DISK_BLOCK_IO_PCT
----------------------------------
The percentage of block IOs of the total physical IOs during the interval.
On SUN, these are physical IOs generated by file system access and do not
include virtual memory IOs, or IOs relating to raw disk access. These are
IOs for inode and superblock updates which are handled through the buffer
cache. Because virtual memory IOs are not credited to the process, the block

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, 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 AIX, these are physical IOs generated by file system access and do not
include virtual memory IOs, or IOs relating to raw disk access. These do
include the IO of the inode (system write) and the file system data IO.

Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
On SUN, these are physical IOs generated by file system access and do not
include virtual memory IOs, or IOs relating to raw disk access. These are
IOs for inode and superblock updates which are handled through the buffer
cache. Because virtual memory IOs are not credited to the process, the block
IOs tend to be much lower on SunOS 5.X than they are on SunOS 4.1.X systems.
When a file is accessed on SunOS 5.X or later, 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, 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 AIX, these are physical IOs generated by file system access and do not
include virtual memory IOs, or IOs relating to raw disk access. These do
include the IO of the inode (system write) and the file system data IO.

GBL_DISK_LOGL_IO
----------------------------------
The number of logical IOs made 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.

disks further distort the relationship between logical and physical IO, since
physical writes are doubled.
GBL_DISK_LOGL_READ_RATE
----------------------------------
On most systems, this is The average number of logical reads per second made
during the interval. On SUN, this is the average number of logical block
reads per second made during the interval. On Windows, this includes both
buffered (cached) read requests and unbuffered reads.
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.
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 Solaris non-global zones with Uncapped CPUs, this metric shows data from
the global zone.
GBL_DISK_LOGL_READ_RATE_CUM
----------------------------------
On most Unix systems, this is the average number of logical reads per second
over the cumulative collection time. On SUN, this is the average number of
logical block reads per second 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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
On many Unix systems, logical disk IOs are measured by counting the read

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.
On Solaris non-global zones, this metric is N/A.
On AIX System WPARs, this metric is NA.
GBL_DISK_PHYS_BYTE_RATE
----------------------------------
The average number of KBs per second at which data was transferred to and

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.

----------------------------------
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 +

On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
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_RATE
----------------------------------
The number of physical reads per second 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, 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

system, then data for that device is being collected.
On Solaris non-global zones, this metric is N/A.
On AIX System WPARs, this metric is NA.
GBL_DISK_PHYS_READ_RATE_CUM
----------------------------------
The average number of physical reads per second 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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a

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
----------------------------------
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. This can be determined by checking the “by-disk” data when provided

over the cumulative collection time. Only local disks are counted in this
measurement. NFS devices are excluded.

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.
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

On AIX System WPARs, this metric is NA.
GBL_DISK_TIME_PEAK
----------------------------------

of the total interval (that is, the average utilization).

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

subsystem bottleneck situation. A bottleneck may not be in the physical disk
drive itself, but elsewhere in the IO path.

On AIX System WPARs, this metric is NA.
GBL_DISK_UTIL_PEAK_CUM
----------------------------------

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 thread) was first started, or b) the performance

the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
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.
On Solaris non-global zones, this metric is N/A.
On AIX System WPARs, this metric is NA.
GBL_DISK_VM_IO_CUM
----------------------------------
The total number of virtual memory 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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data

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_IO_PCT
----------------------------------
On HP-UX and AIX, this is the percentage of virtual memory IO requests of
total physical disk IOs during the interval.
On the other Unix systems, this is the percentage of virtual memory IOs of
the total number of physical IOs 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.

GBL_DISK_VM_IO_PCT_CUM
----------------------------------
The percentage of virtual memory IOs of 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 thread) was first started, or b) the performance

On HP-UX, all cumulative collection times and intervals start when the

GBL_DISK_VM_IO_RATE
----------------------------------
The number of virtual memory IOs per second made during the interval. Only
local disks are counted in this measurement. NFS devices are excluded.

On Solaris non-global zones, this metric is N/A.
On AIX System WPARs, this metric is NA.
GBL_DISK_VM_IO_RATE_CUM
----------------------------------
On HP-UX and AIX, this is the number of virtual memory IOs per second made
over the cumulative collection time.
On the other Unix systems, the number of virtual memory IOs per second 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 thread) was first started, or b) the performance

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_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.
On Solaris non-global zones, this metric shows data from the global zone.
GBL_GMTOFFSET
----------------------------------
The difference, in minutes, between local time and GMT (Greenwich Mean Time).
GBL_IGNORE_MT
----------------------------------
This boolean value indicates whether the CPU normalization is on or off. If
the metric value is “true”, CPU related metrics in the global class will
report values which are normalized against the number of active cores on the
system.
If the metric value is “false”, CPU related metrics in the global class will
report values which are normalized against the number of CPU threads on the
system.
If CPU MultiThreading is turned off this configuration option is a no-op and
the metric value will be “true”.
On Linux, this metric will only report “true” if this configuration is on and
if the kernel provides enough information to determine whether MultiThreading
is turned on.
On HPUX, this metric will report “na” if the processor doesn’t support the
feature.
GBL_INTERRUPT
----------------------------------
The number of IO interrupts during the interval.
On Solaris non-global zones with Uncapped CPUs, this metric shows data from
the global zone.
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.
On Solaris non-global zones with Uncapped CPUs, this metric shows data from
the global zone.
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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.

model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.

for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
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 thread) was first started, or b) the performance

the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
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_LOADAVG
----------------------------------
The 1 minute load average of the system obtained at the time of logging.
On windows this is the load average of the system over the interval. Load
average on windows is the average number of threads that have been waiting in
ready state during the interval. This is obtained by checking the number of
threads in ready state every sub proc interval, accumulating them over the
interval and averaging over the interval.
On Solaris non-global zones, this metric shows data from the global zone.
GBL_LOADAVG15
----------------------------------
The 15 minute load average of the system obtained at the time of logging.
GBL_LOADAVG5
----------------------------------
The 5 minute load average of the system obtained at the time of logging.
On Solaris non-global zones, this metric shows data from the global zone.
GBL_LOADAVG_CUM
----------------------------------
The average load average of the system over the cumulative collection time.
The cumulative collection time is defined from the point in time when
either: a) the process (or thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
GBL_LOADAVG_HIGH
----------------------------------
The highest value of the load average 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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.

won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
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 Perf Agent 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, “Sys WPAR” on system WPAR, “Zone”
on Solaris Zones, “VMware” on recognized VMware ESX guest and VMware ESX
Server console, “Hyper-V” on Hyper-V host, else “NoVM”.
In conjunction with GBL_LS_ROLE this metric could be used to identify the
environment in which Perf Agent/Glance is running. For example, if
GBL_LS_ROLE is “Guest” and GBL_LS_TYPE is “VMware” then PA/Glance is running
on a VMware Guest.
GBL_MACHINE
----------------------------------
An ASCII string representing the Processor Architecture. And machine hardware
model is represented by GBL_MACHINE_MODEL metric.
GBL_MACHINE_MODEL
----------------------------------
The CPU model. This is similar to the information returned by the
GBL_MACHINE metric and the uname command(except for Solaris 10 x86/x86_64).
However, this metric returns more information on some processors.
On HP-UX, this is the same information returned by the model command.
GBL_MEM_ARC
----------------------------------
On Solaris, this value indicates the amount of Adaptive Replacement
Cache(ARC) used by ZFS
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.
GBL_MEM_ARC_UTIL
----------------------------------
The percentage of physical memory used by ZFS ARC during the interval.
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

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.
GBL_MEM_AVAIL
----------------------------------
The amount of physical available memory in the system (in MBs unless
otherwise specified).
On Windows, memory resident operating system code and data is not included as
available memory.
On Solaris non-global zones with Uncapped Memory scenario, this metric value
is same as seen in global zone.
GBL_MEM_CACHE
----------------------------------
The amount of physical memory (in MBs unless otherwise specified) used by the
buffer cache during the interval.
On HP-UX 11i v2 and below, the buffer cache is a memory pool used by the
system to stage disk IO data for the driver.
On HP-UX 11i v3 and above this metric value represents the usage of the file
system buffer cache which is still being used for file system metadata.
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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
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.
On Solaris non-global zones, this metric is N/A.
On AIX System WPARs, this metric is NA.
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.

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 SUN, this is the highest interval percentage of physical reads satisfied
in memory (rather than going to disk) over the cumulative collection time.
This includes inode, indirect block and cylinder group related disk reads,

won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
GBL_MEM_CACHE_UTIL
----------------------------------
The percentage of physical memory used by the buffer cache during the
interval.
On HP-UX 11i v2 and below, the buffer cache is a memory pool used by the
system to stage disk IO data for the driver.
On HP-UX 11i v3 and above this metric value represents the usage of the file
system buffer cache which is still being used for file system metadata.
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_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.

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_LONGS_PCT
----------------------------------
The percentage of time a pathname component was too long to be found in the
directory name lookup cache 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.

GBL_MEM_DNLC_LONGS_PCT_CUM
----------------------------------
The percentage of time a pathname component was too long to be found in the
directory name lookup cache over the cumulative collection time.
The cumulative collection time is defined from the point in time when
either: a) the process (or thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.

GBL_MEM_DNLC_LONGS_PCT_HIGH
----------------------------------
The highest percentage of time during any one interval that a pathname
component was too long to be found in the directory name lookup cache over
the cumulative collection time.
The cumulative collection time is defined from the point in time when
either: a) the process (or thread) was first started, or b) the performance

GBL_MEM_ENTL_MAX
----------------------------------
In a virtual environment, this metric indicates the maximum amount of memory
configured for this logical system. The value is -3 if entitlement is
‘Unlimited’ for this logical system.
On a recognized VMware ESX guest, where VMware guest SDK is disabled, the
value is “na”
On Solaris non-global zones, this metric value is equivalent to ‘capped-
memory’ value for ‘zonecfg -z zonename info’ command.
On a standalone system this metric is equivalent to GBL_MEM_PHYS.
GBL_MEM_ENTL_UTIL
----------------------------------
In a virtual environment, this metric indicates the maximum amount of memory
utilized against memory configured for this logical system.
GBL_MEM_FILE_PAGEIN_RATE
----------------------------------
The number of page ins from the file system per second during the interval.
On Solaris, this is the same as the “fpi” value from the “vmstat -p” command,
divided by page size in KB.
On Linux, the value is reported in kilobytes and matches the ‘io/bi’ values
from vmstat.
On Solaris non-global zones with Uncapped Memory scenario, this metric value
is same as seen in global zone.
GBL_MEM_FILE_PAGEOUT_RATE
----------------------------------
The number of page outs to the file system per second during the interval.
On Solaris, this is the same as the “fpo” value from the “vmstat -p” command,
divided by page size in KB.
On Linux, the value is reported in kilobytes and matches the ‘io/bo’ values
from vmstat.
On Solaris non-global zones with Uncapped Memory scenario, this metric value
is same as seen in global zone.
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.
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.
On uncapped solaris zones, the metric indicates the amount of memory that is
available across the whole system that is not consumed by the global zone and
other non-global zones. In case of capped solaris zones, the metric indicates
the amount of memory that is not consumed by this zone against the memory cap
set.
On Linux, this metric is sum of ‘free’ and ‘cached’ memory.
On Solaris non-global zones with Uncapped Memory scenario, this metric value
is same as seen in global zone.
Locality Domain metrics are available on HP-UX 11iv2 and above.
GBL_MEM_FREE and LDOM_MEM_FREE, as well as the memory utilization metrics
derived from them, may not always fully match. GBL_MEM_FREE represents free
memory in the kernel’s reservation layer while LDOM_MEM_FREE shows actual
free pages. If memory has been reserved but not actually consumed from the
Locality Domains, the two values won’t match. Because GBL_MEM_FREE includes
pre-reserved memory, the GBL_MEM_* metrics are a better indicator of actual
memory consumption in most situations.
GBL_MEM_FREE_UTIL
----------------------------------
The percentage of physical memory that was free at the end of the interval.
On Solaris non-global zones with Uncapped Memory scenario, this metric value
is same as seen in global zone.
GBL_MEM_PAGEIN
----------------------------------
The total number of page ins from the disk during the interval.
On HP-UX, Solaris, Linux and AIX, this reflects paging activity between
memory and paging space. It does not include activity between memory and
file systems.
On Windows, this includes paging activity for both file systems and paging
space.
On HP-UX, this is the same as the “page ins” value from the “vmstat -s”
command. On AIX, this is the same as the “paging space page ins” value.
Remember that “vmstat -s” reports cumulative counts.
On Solaris non-global zones with Uncapped Memory scenario, this metric value
is same as seen in global zone.
GBL_MEM_PAGEIN_BYTE
----------------------------------

message will be logged to indicate this.
On HP-UX, Solaris, Linux and AIX, this reflects paging activity between
memory and paging space. It does not include activity between memory and
file systems.
On Windows, this includes paging activity for both file systems and paging
space.

----------------------------------
The total number of page outs to the disk per second during the interval.

On Solaris, this is the same as the sum of the “epo” and “apo” values from
the “vmstat -p” command, divided by the page size in KB.
On Windows, this counter also includes paging traffic on behalf of the system
cache to access file data for applications and so may be high when there is
no memory pressure.

is same as seen in global zone.
GBL_MEM_PAGEOUT_RATE_CUM
----------------------------------
The average number of page outs to the disk per second over the cumulative
collection time. This includes pages paged out to paging space and, except
for AIX, to the file system.
The cumulative collection time is defined from the point in time when
either: a) the process (or thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up

after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a

----------------------------------
The number of page requests to or from the disk during the interval.
On HP-UX, Solaris, and AIX, this includes pages paged to or from the paging
space and not to the file system.
On Windows, this includes pages paged to or from both paging space and the
file system.
On HP-UX, this is the same as the sun of the “page ins” and “page outs”
values from the “vmstat -s” command. On AIX, this is the same as the sum of
the “paging space page ins” and “paging space page outs” values. Remember
that “vmstat -s” reports cumulative counts.

Higher than normal rates can indicate either a memory or a disk bottleneck.
Compare GBL_DISK_UTIL_PEAK and GBL_MEM_UTIL to determine which resource is
more constrained. High rates may also indicate memory thrashing caused by a

won’t include times accumulated prior to the performance tool’s start and a

GBL_MEM_PHYS
----------------------------------
The amount of physical memory in the system (in MBs unless otherwise
specified).
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.
On Solaris non-global zones with Uncapped Memory scenario, this metric value
is same as seen in global zone.
GBL_MEM_SWAP
----------------------------------
The total number of swap ins and swap outs (or deactivations and
reactivations on HP-UX) during the interval.
On Linux and 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 Linux and 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.

----------------------------------
The number of KBs transferred in from disk due to swap ins (or reactivations
on HP-UX) during the interval.

GBL_MEM_SWAPIN_BYTE_CUM
----------------------------------

Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data

Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
On Linux and 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_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

tool was first started, or c) the cumulative counters were reset (relevant

model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
On Linux and 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_SWAPOUT_RATE_HIGH
----------------------------------
The highest number of swap outs (or deactivations on HP-UX) 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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.

GBL_MEM_SWAP_CUM
----------------------------------
The total number of swap ins and swap outs (or deactivations and
reactivations on HP-UX) over the cumulative collection time.
The cumulative collection time is defined from the point in time when
either: a) the process (or thread) was first started, or b) the performance

GBL_MEM_SYS
----------------------------------
The amount of physical memory (in MBs unless otherwise specified) used by the
system (kernel) during the interval. System memory does not include the
buffer cache. 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.
On Solaris non-global zones, this metric shows value as 0.
GBL_MEM_SYS_AND_CACHE_UTIL
----------------------------------
The percentage of physical memory used by the system (kernel) and the buffer
cache at the end of the interval.
On HP-UX 11iv3, this includes file cache 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.
On Solaris non-global zones, this metric is N/A.
GBL_MEM_SYS_UTIL
----------------------------------
The percentage of physical memory used by the system during the interval.
System memory does not include the buffer cache. 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.
On Solaris non-global zones, this metric shows value as 0.
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.
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 11iv3 and above, this includes file cache. This excludes file cache
when cachemem parameter in the parm file is set to free.
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 Linux, the value of this metric includes file cache when the cachemem
parameter in the parm file is set to user.
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.
This excludes ZFS ARC cache when cachemem parameter in the parm file is set
to free.
On AIX, this excludes file cache when cachemem parameter in the parm file is
set to free.
Locality Domain metrics are available on HP-UX 11iv2 and above.
GBL_MEM_FREE and LDOM_MEM_FREE, as well as the memory utilization metrics
derived from them, may not always fully match. GBL_MEM_FREE represents free
memory in the kernel’s reservation layer while LDOM_MEM_FREE shows actual
free pages. If memory has been reserved but not actually consumed from the
Locality Domains, the two values won’t match. Because GBL_MEM_FREE includes
pre-reserved memory, the GBL_MEM_* metrics are a better indicator of actual
memory consumption in most situations.
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 system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a

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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant

the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
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.
This does not include data for loopback interface.
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

The number of NFS calls the local system has made as either a NFS client or
server during the interval.
This includes both successful and unsuccessful calls. Unsuccessful calls are
those that cannot be completed due to resource limitations or LAN packet
errors.
NFS calls include create, remove, rename, link, symlink, mkdir, rmdir,
statfs, getattr, setattr, lookup, read, readdir, readlink, write, writecache,
null and root operations.
On AIX System WPARs, this metric is NA.
GBL_NFS_CALL_RATE
----------------------------------
The number of NFS calls per second the system made as either a NFS client or
NFS server during the interval.
Each computer can operate as both a NFS server, and as an NFS client.

calls are those that cannot be completed due to resource limitations or LAN
packet errors.
NFS calls include create, remove, rename, link, symlink, mkdir, rmdir,
statfs, getattr, setattr, lookup, read, readdir, readlink, write, writecache,
null and root operations.
On AIX System WPARs, this metric is NA.
GBL_NFS_CLIENT_BAD_CALL

GBL_NFS_CLIENT_BAD_CALL_CUM
----------------------------------
The number of failed NFS client calls over the cumulative collection time.
Calls fail due to lack of system resources (lack of virtual memory) as well
as network errors.
The cumulative collection time is defined from the point in time when
either: a) the process (or thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.

model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after

On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
NFS Version 2 write operations consist of setattr, write, writecache,
create, remove, rename, link, symlink, mkdir, and rmdir.
NFS Version 3 write operations consist of setattr, write, create, mkdir,
symlink, mknod, remove, rmdir, rename, link, pathconf, and commit.
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 Perf
Agent is installed in a guest or in a standalone system this value will be 0.
On Solaris non-global zones, this metric shows value as 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 999 applications.
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. For AIX, this metric indicates the maximum number
of CPUs the system ever had.
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.
On Solaris non-global zones with Uncapped CPUs, this metric shows data from
the global zone.
On AIX System WPARs, this metric value is identical to the value on AIX
Global Environment.
The Linux kernel currently doesn’t provide any metadata information for
disabled CPUs. This means that there is no way to find out types, speeds, as
well as hardware IDs or any other information that is used to determine the
number of cores, the number of threads, the HyperThreading state, etc... If
the agent (or Glance) is started while some of the CPUs are disabled, some of
these metrics will be “na”, some will be based on what is visible at startup
time. All information will be updated if/when additional CPUs are enabled and
information about them becomes available. The configuration counts will
remain at the highest discovered level (i.e. if CPUs are then disabled, the
maximum number of CPUs/cores/etc... will remain at the highest observed
level). It is recommended that the agent be started with all CPUs enabled.
GBL_NUM_CPU_CORE
----------------------------------
This metric provides the total number of CPU cores on a physical system. On
VMs, this metric shows information according to resources available on that
VM. On non HP-UX system, this metric is equivalent to active CPU cores. On
AIX System WPARs, this metric value is identical to the value on AIX Global
Environment. On Windows, this metric will be “na” on Windows Server 2003
Itanium systems.
The Linux kernel currently doesn’t provide any metadata information for

the agent (or Glance) is started while some of the CPUs are disabled, some of
these metrics will be “na”, some will be based on what is visible at startup

remain at the highest discovered level (i.e. if CPUs are then disabled, the
maximum number of CPUs/cores/etc... will remain at the highest observed
level). It is recommended that the agent be started with all CPUs enabled.
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.
On Solaris non-global zones, this metric shows value as 0.
On AIX System WPARs, this metric shows value as 0.
GBL_NUM_LS
----------------------------------
This indicates the number of LS hosted in a system. If Perf Agent is
installed in a guest or in a standalone system this value will be 0.
On Solaris non-global zones, this metric shows value as 0.
GBL_NUM_LV
----------------------------------
The sum of configured logical volumes.
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_SOCKET
----------------------------------
The number of physical cpu sockets on the system. On VMs, this metric shows
information according to resources available on that VM.
On Windows, this metric will be “na” on Windows Server 2003 Itanium systems.
GBL_NUM_SWAP
----------------------------------
The number of configured swap areas.
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. On disabling the Logical Volume Class
of metrics, this value will be reported as NA
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_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_RENICE_PRI_LIMIT
----------------------------------
User priorities range from -x to +x where the value of x is configurable.
This is the configured value x. This defines the range of possible values
for altering the priority of processes in the time-sharing class.
GBL_RUN_QUEUE
----------------------------------
On UNIX systems except Linux, this is the average number of threads waiting
in the runqueue over the interval. The average is computed against the number
of times the run queue is occupied instead of time. The average is updated by
the kernel at a fine grain interval, only when the run queue is occupied. It
is not averaged against the interval and can therefore be misleading for long
intervals when the run queue is empty most or part of the time. This value
matches runq-sz reported by the “sar -q” command. The GBL_LOADAVG* metrics
are better indicators of run queue pressure.
On Linux and Windows, this is instantaneous value obtained at the time of
logging. On Linux, it shows the number of threads waiting in the runqueue.
On Windows, it shows the Processor Queue Length.
On Unix systems, GBL_RUN_QUEUE will typically be a small number. Larger than
normal values for this metric indicate CPU contention among threads. 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 threads
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 threads 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 threads. 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 threads 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
threads can be active at any given time); and the cpu queue is 16 (half of
the threads waiting in the cpu queue that are ready to run, plus one for each
active thread).
This illustrates that the run queue is the average of number of threads
waiting in the runqueue for all processors; the pri queue is the number of
threads that are blocked on “PRI” (priority); and the cpu queue is the number
of threads in the cpu queue that are ready to run, including the threads
using the CPU.
On Solaris non-global zones, this metric shows data from the global zone.
GBL_RUN_QUEUE_CUM
----------------------------------
On UNIX systems except Linux, this is the average number of threads waiting
in the runqueue over the cumulative collection time.
On Linux, this is approximately the number of threads waiting in the runqueue
over the cumulative collection time.
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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
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 threads 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 threads. The approximate
values now shown are:
GBL_RUN_QUEUE = 2.0
GBL_PRI_QUEUE = 8.0
GBL_CPU_QUEUE = 16.0

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
threads can be active at any given time); and the cpu queue is 16 (half of
the threads waiting in the cpu queue that are ready to run, plus one for each
active thread).
This illustrates that the run queue is the average of number of threads
waiting in the runqueue for all processors; the pri queue is the number of
threads that are blocked on “PRI” (priority); and the cpu queue is the number
of threads in the cpu queue that are ready to run, including the threads
using the CPU.
GBL_RUN_QUEUE_HIGH
----------------------------------
On UNIX systems except Linux, this is the highest value of average number of
threads waiting in the runqueue during any interval over the cumulative
collection time.
On Linux, this is the highest value of number of threads waiting in the
runqueue during any interval over the cumulative collection time.
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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
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_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_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.
On Solaris non-global zones, this metric is N/A.
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.
On Solaris non-global zones, this metric is N/A.
On AIX System WPARs, this metric is NA.
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.
On Solaris non-global zones, this metric is N/A.
On AIX System WPARs, this metric is NA.
GBL_SWAP_SPACE_DEVICE_AVAIL
----------------------------------
The amount of swap space configured on disk devices exclusively as swap space
(in MB).
On Unix systems, this metric is updated every 30 seconds or the sampling
interval, whichever is greater.
On Solaris non-global zones, this metric is N/A.
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.
On Solaris non-global zones, this metric is N/A.
GBL_SWAP_SPACE_MEM_AVAIL
----------------------------------
The amount of physical memory available for pseudo swap (in MB).
On Unix systems, this metric is updated every 30 seconds or the sampling
interval, whichever is greater.
On Solaris non-global zones, this metric is N/A.
GBL_SWAP_SPACE_MEM_UTIL
----------------------------------
The percent of physical memory available for pseudo swap currently allocated
to running processes.
On Unix systems, this metric is updated every 30 seconds or the sampling
interval, whichever is greater.
On Solaris non-global zones, this metric is N/A.
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.
On Solaris non-global zones, this metric is N/A.
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.
On Solaris non-global zones, this metric is N/A.
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 AIX System WPARs, this metric is NA.
On Solaris non-global zones, this metric is N/A. On Unix systems, this
metric is updated every 30 seconds or the sampling interval, whichever is
greater.
GBL_SWAP_SPACE_USED_UTIL
----------------------------------
This is the percentage of swap space used.
On HP-UX, “Used %” indicates percentage of swap space written to disk (or
locked in memory), rather than reserved. This is the same as percentage of
((USED: total - reserve)/total)*100, as reported by the “swapinfo -mt”
command.
On SUN, “Used %” indicates percentage of swap space 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 percentage of ((bytes allocated)/total)*100, 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 percentage of ((Swap: used)/total)*100, as reported
by the “free -m” command.
On Unix systems, this metric is updated every 30 seconds or the sampling
interval, whichever is greater.
On Solaris non-global zones, this metric is N/A.
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.
On Solaris non-global zones, this metric is N/A.
On AIX System WPARs, this metric is NA.
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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.

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_BYTE_RATE
----------------------------------
The number of KBs transferred per second via read and write system calls
during the interval. This includes reads and writes to all devices including
disks, terminals and tapes.
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 Glance
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

tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred

Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit

volume. This metric is reported as “na” for volume groups since it is not
applicable.
On AIX, this is the total number of logical partitions configured for this
logical volume.
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

volume groups since it is not applicable.
LV_READ_BYTE_RATE_CUM
----------------------------------
The average number of physical KBs per second read from this logical volume

for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
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.
DiskSuite metadevices are not supported. This metric is reported as “na” for
volume groups since it is not applicable.
LV_READ_RATE_CUM
----------------------------------
The average number of physical reads per second for this volume over the

Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
LV_SPACE_UTIL
----------------------------------
Percentage of the logical volume file system space in use during the
interval.
A value of “na” is displayed for volume groups and logical volumes which have
no mounted filesystem.
LV_STATE_LV
----------------------------------
On SUN, this is the kernel state of this volume. Enabled means the volume
block device can be used. Detached means the volume block device cannot be
used, but ioctl’s will still be accepted and the plex block devices will
still accept reads and writes. Disabled means that the volume or its plexes
cannot be used for any operations. DiskSuite metadevices are not supported.
This metric is reported as “na” for volume groups since it is not applicable.
On AIX, this is the state of this logical volume in the volume group. The
normal state of a logical volume should be “open/syncd”, which means that the
logical volume is open and clean.
LV_TYPE
----------------------------------
Either “G” or “V”, indicating either a volume/disk group (“G”) or a logical
volume (“V”). On SUN, it can also be a Disk Suite meta device (“S”).
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_TYPE_LV
----------------------------------
This metric is only applicable for DiskSuite metadevices and it can be one of
the following:
* TRANS
* RAID
* MIRROR
* CONCAT/STRIPE
TRANS A metadevice called the
trans device manages the UFS
log. The trans normally has 2
metadevices:
MASTER DEVICE, contains the
file system that is being
logged. Can be used as a
block device (up to 2 Gbytes)
or a raw device (up to
1 Tbyte).
LOGGING DEVICE, contains the
log and can be shared by
several file systems. The log
is a sequence of cords, each
of which describes a change
to a file system.
RAID Redundant Array of Inexpen-
sive Disks. A scheme for
classifying data distribution
and redundancy.
MIRROR For high data availability,
DiskSuite can write data in
metadevices to other meta-
devices. A mirror is a meta-
device made of one or more
concatenations or striped
metadevices. Concatenation
is the combining of two or
more physical components into
a single metadevice by
treating slices (partitions)
as a logical device.
STRIPE (or Striping) For increased
performance, you can create
striped metadevices (or
“stripes”). Striping is
creating a single metadevice
by interlacing data on slices
across disks. After a
striped metadevice is
created, read/write requests
are spread to multiple disk
controllers, increasing
performance.
LV_WRITE_BYTE_RATE
----------------------------------
The number of KBs per second written to this logical volume during the
interval.
DiskSuite metadevices are not supported. This metric is reported as “na” for
volume groups since it is not applicable.
LV_WRITE_BYTE_RATE_CUM
----------------------------------
The average number of KBs per second written to this logical 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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
DiskSuite metadevices are not supported. This metric is reported as “na” for
volume groups since it is not applicable.
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.
DiskSuite metadevices are not supported. This metric is reported as “na” for
volume groups since it is not applicable.
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.
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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
PROC_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 999 user-
defined applications, which are defined in the parm file.
PROC_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_CHILD_CPU_SYS_MODE_UTIL
----------------------------------
The percentage of system time accumulated by this process’s children
processes during the interval.
On Unix systems, when a process terminates, its CPU counters (user and
system) are accumulated in the parent’s “children times” counters. This
occurs when the parent waits for (or reaps) the child. See getrusage(2). If
the process is an orphan process, its parent becomes the init(1m) process,
and its CPU times will be accumulated to the init process upon termination.
The PROC*_CHILD_* metrics attempt to report these counters in a meaningful
way. If these counters were reported unconditionally as they are incremented,
they would be misleading. For example, consider a shell process that forks
another process and that process accumulates 100 minutes of CPU time. When
that process terminates, the shell would report a huge child time utilization
for that interval even though it was generally idle, waiting for that child
to terminate. The child process was most likely already reported in previous
intervals as it used the CPU time, and therefore it would be confusing to
report this time in the parent. If, on the other hand, a process was
continuously forking short-lived processes during the interval, it would be
useful to report the CPU time used by those children processes. The simple
algorithm chosen is to only report children times when their total CPU time
is less than the process alive interval, and zero otherwise. It is not fool-
proof but it generally yields the right results, i.e., if a process reports
high child time utilization for several intervals in a row, it could be a
runaway forking process. An example of such a runaway process (or “fork
bomb”) is:
while true ; do ps -ef | grep something done
Moderate children times are also a useful way to identify daemons that rely
on child processes, or, in the case of the init process it may indicate that
many short-lived orphan processes are being created.
Note that this metric is only valid at the process level. It reports CPU time
of processes forked and does not report on threads created by processes. The
PROC*_CHILD* metrics have no meaning at the thread level, therefore the
thread metric of the same name, on systems that report per-thread data, will
show “na”.
PROC_CHILD_CPU_TOTAL_UTIL
----------------------------------
The percentage of system + user time accumulated by this process’s children
processes during the interval.
On Unix systems, when a process terminates, its CPU counters (user and
system) are accumulated in the parent’s “children times” counters. This
occurs when the parent waits for (or reaps) the child. See getrusage(2). If
the process is an orphan process, its parent becomes the init(1m) process,
and its CPU times will be accumulated to the init process upon termination.
The PROC*_CHILD_* metrics attempt to report these counters in a meaningful

to terminate. The child process was most likely already reported in previous

continuously forking short-lived processes during the interval, it would be

algorithm chosen is to only report children times when their total CPU time
is less than the process alive interval, and zero otherwise. It is not fool-
proof but it generally yields the right results, i.e., if a process reports
high child time utilization for several intervals in a row, it could be a
runaway forking process. An example of such a runaway process (or “fork

Moderate children times are also a useful way to identify daemons that rely
on child processes, or, in the case of the init process it may indicate that
many short-lived orphan processes are being created.
Note that this metric is only valid at the process level. It reports CPU time
of processes forked and does not report on threads created by processes. The
PROC*_CHILD* metrics have no meaning at the thread level, therefore the
thread metric of the same name, on systems that report per-thread data, will
show “na”.
PROC_CHILD_CPU_USER_MODE_UTIL
----------------------------------
The percentage of user time accumulated by this process’s children processes
during the interval.
On Unix systems, when a process terminates, its CPU counters (user and
system) are accumulated in the parent’s “children times” counters. This
occurs when the parent waits for (or reaps) the child. See getrusage(2). If
the process is an orphan process, its parent becomes the init(1m) process,
and its CPU times will be accumulated to the init process upon termination.

algorithm chosen is to only report children times when their total CPU time
is less than the process alive interval, and zero otherwise. It is not fool-

Moderate children times are also a useful way to identify daemons that rely
on child processes, or, in the case of the init process it may indicate that
many short-lived orphan processes are being created.
Note that this metric is only valid at the process level. It reports CPU time
of processes forked and does not report on threads created by processes. The
PROC*_CHILD* metrics have no meaning at the thread level, therefore the
thread metric of the same name, on systems that report per-thread data, will
show “na”.
PROC_CPU_ALIVE_SYS_MODE_UTIL
----------------------------------
The total CPU time consumed by a process (or kernel thread, if HP-UX/Linux
Kernel 2.6 and above) in system mode as a percentage of the time it is alive
during the interval. On platforms other than HPUX, If the ignore_mt flag is
set(true) in parm file, this metric will report values normalized against the
number of active cores in the system.
If the ignore_mt flag is not set(false) in parm file, this metric will report
values normalized against the number of threads in the system. This flag will
be a no-op if Multithreading is turned off.
On HPUX, CPU utilization normalization is controlled by the “-ignore_mt”
option of the midaemon(1m). To change normalization from core-based to
logical-cpu-based, or vice-versa, all performance components (scopeux,
glance, perfd) must be shut down and the midaemon restarted in the desired
mode. To start the midaemon with “-ignore_mt” by default, this option should
be added in the /etc/rc.config.d/ovpa control file. Refer to the
documentation regarding ovpa startup. Note that, on HPUX, unlike other
platforms, specifying core-based normalization affects CPU, application,
process and thread metrics.
PROC_CPU_ALIVE_TOTAL_UTIL
----------------------------------
The total CPU time consumed by a process (or kernel thread, if HP-UX/Linux
Kernel 2.6 and above) as a percentage of the time it is alive during the
interval. On platforms other than HPUX, If the ignore_mt flag is set(true)
in parm file, this metric will report values normalized against the number of
active cores in the system.
If the ignore_mt flag is not set(false) in parm file, this metric will report
values normalized against the number of threads in the system. This flag will

PROC_CPU_ALIVE_USER_MODE_UTIL
----------------------------------
The total CPU time consumed by a process (or kernel thread, if HP-UX/Linux
Kernel 2.6 and above) in user mode as a percentage of the time it is alive
during the interval. On platforms other than HPUX, If the ignore_mt flag is
set(true) in parm file, this metric will report values normalized against the
number of active cores in the system.

process and thread metrics.
PROC_CPU_SYS_MODE_TIME
----------------------------------
The CPU time in system mode in the context of the process (or kernel thread,
if HP-UX/Linux Kernel 2.6 and above) during the interval.
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 multi-threaded operating systems, 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 platforms other than HPUX, If the ignore_mt
flag is set(true) in parm file, this metric will report values normalized
against the number of active cores in the system.
If the ignore_mt flag is not set(false) in parm file, this metric will report

PROC_CPU_SYS_MODE_TIME_CUM
----------------------------------
The CPU time in system mode in the context of the process (or kernel thread,
if HP-UX/Linux Kernel 2.6 and above) 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.
The cumulative collection time is defined from the point in time when
either: a) the process (or thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred

On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data

PROC_CPU_SYS_MODE_UTIL
----------------------------------
The percentage of time that the CPU was in system mode in the context of the
process (or kernel thread, if HP-UX/Linux Kernel 2.6 and above) during the
interval.
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.
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.
On multi-threaded operating systems, 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 multi-processor systems, processes which have component kernel threads
executing simultaneously on different processors could have resource
utilization sums over 100%. If there is no CPU multi-threading, the maximum
percentage is 100% times the number of Cores on the system. On a system with
multi-threaded CPUs, the maximum percentage is : 100 % times the number of
cores X 2. ( i.e the total number of logical CPUs on the system). On
platforms other than HPUX, If the ignore_mt flag is set(true) in parm file,
this metric will report values normalized against the number of active cores
in the system.

PROC_CPU_SYS_MODE_UTIL_CUM
----------------------------------
The average percentage of time that the CPU was in system mode in the context
of the process (or kernel thread, if HP-UX/Linux Kernel 2.6 and above) 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

PROC_CPU_TOTAL_TIME
----------------------------------
The total CPU time, in seconds, consumed by a process (or kernel thread, if
HP-UX/Linux Kernel 2.6 and above) during the interval.
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.
On HP-UX, the total CPU time is the sum of the CPU time components for a
process or kernel thread, including system, user, context switch, interrupts
processing, realtime, and nice utilization values.
On multi-threaded operating systems, process usage of a resource is
calculated by summing the usage of that resource by its kernel threads. If

multi-threaded CPUs, the maximum percentage is : 100 % times the number of
cores X 2. ( i.e the total number of logical CPUs on the system). On
platforms other than HPUX, If the ignore_mt flag is set(true) in parm file,
this metric will report values normalized against the number of active cores
in the system.
If the ignore_mt flag is not set(false) in parm file, this metric will report
values normalized against the number of threads in the system. This flag will
be a no-op if Multithreading is turned off.
On HPUX, CPU utilization normalization is controlled by the “-ignore_mt”
option of the midaemon(1m). To change normalization from core-based to
logical-cpu-based, or vice-versa, all performance components (scopeux,
glance, perfd) must be shut down and the midaemon restarted in the desired
mode. To start the midaemon with “-ignore_mt” by default, this option should
be added in the /etc/rc.config.d/ovpa control file. Refer to the
documentation regarding ovpa startup. Note that, on HPUX, unlike other
platforms, specifying core-based normalization affects CPU, application,
process and thread metrics.
PROC_CPU_TOTAL_TIME_CUM
----------------------------------
The total CPU time consumed by a process (or kernel thread, if HP-UX/Linux
Kernel 2.6 and above) 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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
This is calculated as
PROC_CPU_TOTAL_TIME_CUM =
PROC_CPU_SYS_MODE_TIME_CUM +
PROC_CPU_USER_MODE_TIME_CUM
On multi-threaded operating systems, 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 platforms other than HPUX, If the ignore_mt
flag is set(true) in parm file, this metric will report values normalized
against the number of active cores in the system.

PROC_CPU_TOTAL_UTIL
----------------------------------
The total CPU time consumed by a process (or kernel thread, if HP-UX/Linux
Kernel 2.6 and above) as a percentage of the total CPU time available during
the interval.
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.
On HP-UX, the total CPU utilization is the sum of the CPU utilization
components for a process or kernel thread, including system, user, context
switch, interrupts processing, realtime, and nice utilization values.
On multi-threaded operating systems, 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 multi-processor systems, processes which have component kernel threads
executing simultaneously on different processors could have resource
utilization sums over 100%. If there is no CPU multi-threading, the maximum
percentage is 100% times the number of Cores on the system. On a system with
multi-threaded CPUs, the maximum percentage is : 100 % times the number of
cores X 2. ( i.e the total number of logical CPUs on the system).
On platforms other than HPUX, If the ignore_mt flag is set(true) in parm

PROC_CPU_USER_MODE_TIME
----------------------------------
The time, in seconds, the process (or kernel threads, if HP-UX/Linux Kernel

than they are on SunOS 4.1.X systems.
When a file is accessed on SunOS 5.X or later, it is memory mapped by the

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

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).
Note, when a file is accessed on AIX, it is memory mapped by the operating
system, so accesses generate virtual memory IOs, not block IOs.
PROC_DISK_BLOCK_READ_RATE
----------------------------------
The number of block reads per second made by (or for) a process during the
interval.
On Sun 5.X (Solaris 2.X or later), these are physical reads generated by file
system access and do not include virtual memory IOs, or IOs relating to raw
disk access. These are IOs for inode and superblock updates which are
handled through the buffer cache. Because virtual memory IOs are not
credited to the process, the block IOs tend to be much lower on SunOS 5.X
than they are on SunOS 4.1.X systems.

PROC_DISK_BLOCK_WRITE
----------------------------------
Number of block writes made by a process during the interval. Calls destined
for NFS mounted files are not included.

system, so accesses generate virtual memory IOs, not block IOs.
PROC_DISK_BLOCK_WRITE_CUM
----------------------------------
Number of block writes 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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
On Sun 5.X (Solaris 2.X or later), these are physical writes generated by
file system access and do not include virtual memory IOs, or IOs relating to
raw disk access. These are IOs for inode and superblock updates which are

PROC_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 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.
If the following file information was displayed:
and then from that display, the following ncheck command was entered:
ncheck -i 23
An output like the following would be generated:
/dev/dsk/c0t0d0s6:
23 /status.perflbd
The string for an inode is as follows:
or
where:
xxx: Is the file type:
blk - Block device
chr - Character device
dir - Directory file
fifo - FIFO (pipes have a
“fifo” label)
lnk - Soft file link
reg - Regular file
yyy: Is the file domain. Some
examples are ufs (Unix file
system), nfs (NFS), proc
(process file system) and tmpfs
(memory based file system).
In some cases the only information obtainable is the major and minor number
of the file or device. Then, the following format
is displayed where the “n” strings are replaced by the major and minor
numbers respectively. When trying to identify files with this information,
often the major number from this format will equal the minor number of a
device file in the /devices/pseudo directory. For example, ““ is probably one of the following files:
crw-rw-rw- 1 root sys 105, 2 Aug 26 13:13 tl@0:ticlts
crw-rw-rw- 1 root sys 105, 0 Aug 26 13:13 tl@0:ticots
crw-rw-rw- 1 root sys 105, 1 Aug 26 13:13 tl@0:ticotsord
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
char Character device
dir Directory
fifo A pipe or named pipe
file Simple file
link Symbolic file link
other An unknown file type
PROC_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 multi-threaded operating systems, 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 Linux, if thread collection is disabled, only the first thread of each
multi-threaded process is taken into account. This metric will be NA on
kernels older than 2.6.23 or kernels not including CFS, the Completely Fair
Scheduler.
PROC_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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
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 Linux, if thread collection is disabled, only the first thread of each
multi-threaded process is taken into account. This metric will be NA on
kernels older than 2.6.23 or kernels not including CFS, the Completely Fair
Scheduler.
PROC_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
----------------------------------
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_INTEREST
----------------------------------
A string containing the reason(s) why the process or thread is of interest,
based on the thresholds specified in the parm file.
An ‘A’ indicates that the process or thread exceeds the process CPU
threshold, computed using the actual time the process or thread was alive
during the interval.
A ‘C’ indicates that the process or thread exceeds the process CPU threshold,
computed using the collection interval. Currently, the same CPU threshold is
used for both CPU interest reasons.
A ‘D’ indicates that the process or thread exceeds the process disk IO
threshold.
An ‘I’ indicates that the process or thread exceeds the IO threshold.
An ‘M’ indicates that the process exceeds the process memory threshold. This
interest reason is only meaningful for processes and therefore not shown for
threads.
New processes or threads are identified with an ‘N’, terminated processes or
threads are identified with a ‘K’.
Note that the parm file ‘nonew’, ‘nokill’ and ‘shortlived’ settings are
logging only options and therefore ignored in Glance components.
PROC_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
----------------------------------
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
----------------------------------
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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
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_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 multi-threaded operating systems, 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.
Linux release versions vary with regards to the amount of process-level IO
statistics that are available. Some kernels instrument only disk IO, while
some provide statistics for all devices together (including tty and other
devices with disk IO).
When it is available from your specific release of Linux, the PROC_DISK_PHYS*
metrics will report pages of disk IO specifically. The PROC_IO* metrics will
report the sum of all types of IO including disk IO, in Kilobytes or KB
rates. These metrics will have “na” values on kernels that do not support the
instrumentation.
For multi-threaded processes, some Linux kernels only report IO statistics
for the main thread. In that case, patches are available that will allow the
process instrumentation to report the sum of all thread’s IOs, and will also
enable per-thread reporting.
Starting with 2.6.3X, at least some kernels will include IO data from the
children of the process in the process data. This results in misleading
inflated IO metrics for processes that fork a lot of children, such as
shells, or the init(1m) process.
PROC_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.

PROC_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.

PROC_LS_ID
----------------------------------
PROC_LS_ID represents the zone-id of the zone, this process is running in.
This metric is only available on Solaris 10 and above versions.
PROC_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
----------------------------------
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 thread) was first started, or b) the performance

result in a disk page having to be loaded into memory.
PROC_MEM_DATA_VIRT
----------------------------------
On SUN, this is the virtual set size (in KB) of the heap memory for this
process. Note that heap can reside partially in BSS and partially in the
data segment, so its value will not be the same as PROC_REGION_VIRT of the
data segment or PROC_REGION_VIRT_DATA, which is the sum of all data segments
for the process.
On the other non HP-UX systems, this is the virtual set size (in KB) of the
data segment for this process(or kernel thread, if Linux Kernel 2.6 and
above).
A value of “na” is displayed when this information is unobtainable.
On AIX, this is the same as the SIZE value reported by “ps v”.
On Linux this value is rounded to PAGESIZE.
PROC_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
----------------------------------
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_STACK_VIRT
----------------------------------
Size (in KB) of the stack for this process(or kernel thread, if Linux Kernel
2.6 and above).
On SUN, the stack is initialized to 8K bytes.
On Linux this value is rounded to PAGESIZE.
PROC_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_MINOR_FAULT
----------------------------------
Number of minor 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_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.
The cumulative collection time is defined from the point in time when
either: a) the process (or thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
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_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.
On all other Unix systems, the value ranges from 0 to 39. A higher value
causes a process (or kernel thread, if HP-UX/Linux Kernel 2.6 and above) to
be dispatched less.
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_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
----------------------------------
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
----------------------------------
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
----------------------------------
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_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.
PROC_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
HP 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
----------------------------------
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
----------------------------------
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
----------------------------------
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 Perf Agent 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 -F ufs -i 2266
An output like the following would be generated:
/dev/root:
2266 /lib/libXm.so.5.0
The string for an inode is as follows:
or
where:
xxx: Is the file type:
blk - Block device
chr - Character device
dir - Directory file
fifo - FIFO (pipes have a
“fifo” label)
lnk - Soft file link
reg - Regular file
yyy: Is the file domain. Some
examples are ufs (Unix file
system), nfs (NFS), proc
(process file system) and tmpfs
(memory based file system).
If a program is “hard linked” (that is, two files pointing to the same
inode), then a different name may be reported for the text and data regions
than is actually running. Use the “-i” option of the “ls” command to see the
inode numbers.
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_PROT_FLAG
----------------------------------
The protection mode of the process memory segment. It represents
Read/Write/eXecute permissions in the same way as ls(1) does for files. This
metric is available only for regions that have global protection mode. It is
not available (“na”) for regions that use per-page protection.
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_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.
On AIX, as of mid-2010, the OS only provides information for text and data.
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.
On AIX, as of mid-2010, the OS only provides information for text and data.
Other sizes will always be zero. Note also that the total virtual size may
not match the sum of the regions due to inconsistencies in the AIX
measurement interfaces.
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.
On AIX, as of mid-2010, the OS only provides information for text and data.
Other sizes will always be zero. Note also that the total virtual size may
not match the sum of the regions due to inconsistencies in the AIX
measurement interfaces.
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.
On AIX, as of mid-2010, the OS only provides information for text and data.
Other sizes will always be zero. Note also that the total virtual size may
not match the sum of the regions due to inconsistencies in the AIX
measurement interfaces.
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.
On AIX, as of mid-2010, the OS only provides information for text and data.
Other sizes will always be zero. Note also that the total virtual size may
not match the sum of the regions due to inconsistencies in the AIX
measurement interfaces.
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.
On AIX, as of mid-2010, the OS only provides information for text and data.
Other sizes will always be zero. Note also that the total virtual size may
not match the sum of the regions due to inconsistencies in the AIX
measurement interfaces.
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.
On AIX, as of mid-2010, the OS only provides information for text and data.
Other sizes will always be zero. Note also that the total virtual size may
not match the sum of the regions due to inconsistencies in the AIX
measurement interfaces.
PROC_REVERSE_PRI
----------------------------------
The process priority in a range of 0 to 127, with a lower value interpreted
as a higher priority. Since priority ranges can be customized, this metric
provides a standardized way of interpreting priority that is consistent with
other versions of Unix. This is the same value as reported in the PRI field
by the ps command when the -c option is not used.
PROC_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_SIGNAL
----------------------------------
Number of signals seen by the current process (or kernel thread, if HP-UX)
during the lifetime of the process or kernel thread.
PROC_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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
PROC_STARTTIME
----------------------------------
The creation date and time of the process (or kernel thread, if HP-UX/Linux
Kernel 2.6 and above).
PROC_STATE
----------------------------------
A text string summarizing the current state of a process (or kernel thread,
if HP-UX/Linux Kernel 2.6 and above), either:
new This is the first interval
the process has been
displayed.
active Process is continuing.
died Process expired during
the interval.
PROC_STATE_FLAG
----------------------------------
The Unix STATE flag of the process(or kernel thread, if Linux Kernel 2.6 and
above) during the interval.
PROC_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:
SunOS 5.X
String Reason for Process Block
------------------------------------
died Process terminated during
the interval.
new Process was created (via the
exec() system call) during
the interval.
NONE Process is ready to run. It
is not apparent that the
process is blocked.
OTHER Waiting for a reason not
decipherable by the
measurement software.
PMEM Waiting for more primary
memory.
PRI Process is on the run queue.
SLEEP Waiting for an event to
complete.
TRACE Received a signal to stop
because parent is tracing
this process.
ZOMB Process has terminated and
the parent is not waiting.
On SunOS 5.X, instead of putting the scheduler to sleep and waking it up, the
kernel just stops and continues the scheduler as needed. This is done by
changing the state of the scheduler to ws_stop, which is when you see the
TRACE state. This is for efficiency and happens every clock tick so the
“sched” process will always appear to be in a “TRACE” state.
PROC_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_SYSCALL
----------------------------------
The number of system calls this process executed during the interval.
PROC_SYSCALL_CUM
----------------------------------
The number of system calls this process has executed over the cumulative
collection time.
The cumulative collection time is defined from the point in time when
either: a) the process (or thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
PROC_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_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
----------------------------------
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_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
----------------------------------
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
----------------------------------
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
----------------------------------
On Unix systems, this is real user name of a process or 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_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 multi-threaded operating systems, 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 Linux, if thread collection is disabled, only the first thread of each
multi-threaded process is taken into account. This metric will be NA on
kernels older than 2.6.23 or kernels not including CFS, the Completely Fair
Scheduler.
PROC_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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
On multi-threaded operating systems, 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 Linux, if thread collection is disabled, only the first thread of each
multi-threaded process is taken into account. This metric will be NA on
kernels older than 2.6.23 or kernels not including CFS, the Completely Fair
Scheduler.
TBL_BUFFER_CACHE_AVAIL
----------------------------------
The size (in KBs unless otherwise specified) of the file system buffer cache
on the system.
On HP-UX 11i v2 and below, 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). 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 HP-UX 11i v3 and above the limits of the file system buffer cache which is
still being used for file system metadata are automatically set to certain
percentages of filecache_min and filecache_max.
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.
On AIX System WPARs, this metric is NA.
TBL_BUFFER_CACHE_HWM
----------------------------------
The value of the system configurable parameter “bufhwm”. This is the maximum
amount of memory that can be allocated to the buffer cache. Unless otherwise
set in the /etc/system file, the default is 2 percent of system memory.
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_USED_HIGH
----------------------------------
The largest number of buffer headers 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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.

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.

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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred

On Unix systems, this metric is updated every 30 seconds or the sampling
interval, whichever is greater.
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.
On Solaris non-global zones, this metric is N/A.
TBL_FILE_LOCK_USED_HIGH
----------------------------------
The highest number of file locks used by the file system 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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant

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_USED_HIGH
----------------------------------
The highest number of entries in the file table that is 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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant

----------------------------------
The percentage of file table entries currently used by file descriptors.
On Unix systems, this metric is updated every 30 seconds or the sampling

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.

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

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 thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.

midaemon starts. On other Unix systems, non-process collection time starts

for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
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.

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

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_MAX_USERS
----------------------------------
The value of the system configurable parameter “maxusers”. This value
signifies the approximate number of users on a system.
Note, changing this value can significantly affect the performance of a
system because memory allocation calculations are based on it. This value
can be set in the /etc/system file.
On Solaris non-global zones, this metric is N/A.
TBL_MSG_BUFFER_ACTIVE
----------------------------------
The current active 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. This metric only counts the active message queue
buffers, which means that a msgsnd(2) call has been made and the msgrcv(2)
has not yet been done on the queue entry or a msgrcv(2) call is waiting on a
message queue entry.
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”. If the value adds up
to a value > 2048GB, “o/f” may be reported on some platforms.
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

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.

either: a) the process (or thread) was first started, or b) the performance
tool was first started, or c) the cumulative counters were reset (relevant
only to Glance, if available for the given platform), whichever occurred
last.
On HP-UX, all cumulative collection times and intervals start when the
midaemon starts. On other Unix systems, non-process collection time starts
from the start of the performance tool, process collection time starts from
the start time of the process or measurement start time, which ever is older.

(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.
On Unix systems, this metric is updated every 30 seconds or the sampling
interval, whichever is greater.

qo” command.
On Unix systems, this metric is updated every 30 seconds or the sampling
interval, whichever is greater.

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.). If the value adds up to a value > 2048TB, “o/f” may be reported

the start time of the process or measurement start time, which ever is older.
Regardless of the process start time, application cumulative intervals start
from the time the performance tool is started.
On systems where the performance components are 32-bit or where the 64-bit
model is LLP64 (Windows), all INTERVAL_CUM metrics will start reporting “o/f”
(overflow) after the performance agent (or the midaemon on HPUX) has been up
for 466 days and the cumulative metrics will fail to report accurate data
after 497 days. On Linux, Solaris and AIX, if measurement is started after
the system has been up for more than 466 days, cumulative process CPU data
won’t include times accumulated prior to the performance tool’s start and a
message will be logged to indicate this.

----------------------------------
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 and HP Operations Manager (HPOM). 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 alarm generator server (perfalarm), the alarm
generator database server (agdbserver), and the alarm generator
database (agdb) that is managed by agdbserver. The agdb contains
of list of various on/off flags that are set to define when and
where the alarm information is sent.
alarm definitions file
----------------------------------
The text file containing the alarm definitions for the
Performance Collection Component in which alarm conditions are
specified. For the HP Operations agent on UNIX/Linux platforms,
the default file name is alarmdef; for the HP Operations agent on
Windows, the default file name is alarmdef.mwc.
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 HP 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 HP
Operations agent systems. With HP Performance Manager, you view
graphs of a system's 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 on
----------------------------------
The reason for the last recorded process block.
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
----------------------------------

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.
capped
----------------------------------
A capped partition indicates that the logical partition will
never exceed its assigned processing capacity. Any unused
processing resources will be used only by the uncapped partitions
in the shared processor pool.
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.

A daemon that provides collected data to the alarm generator and
analysis product data sources, including scopeux log files or DSI
log files. coda reads the data from the data sources listed in
the datasources configuration file.
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
group when the total system CPU use is at 100%. The system
administrator assigns the CPU entitlement for each process
resource group in the PRM configuration file (/etc/prmconf). The
minimum entitlement for the System group, PRMID 0, is 20%. The
minimum entitlement for all other groups is 1%. PRM distributes
unused time to other groups in proportion to their CPU
entitlement.
CPU queue
----------------------------------
The average number of processes in the "run" state awaiting CPU
scheduling, which includes processes short waited for IOs. This
is calculated from GBL-RUN-QUEUE and the number of times this
metric is updated. This is also a measure of how busy the
system's CPU resource is.
cyclical redundancy check
----------------------------------
(CRC). A networking checksum protocol used to detect
transmission errors.
cylinder
----------------------------------
The tracks of a disk accessible from one position of the head
assembly.
cylinder group

cylinder-group basis.
daemon
----------------------------------
A process that runs continuously in the background but provides
important system services.
data class
----------------------------------
A particular category of data collected by a data collection
process. Single-instance data classes, such as the global class,
contain a single set of metrics that appear only once in any data
source. Multiple-instance classes, such as the application
class, may have many occurrences in a single data source, with
the same set of metrics collected for each occurrence of the
class. (Also known as data type.)
data locality
----------------------------------
The location of data relative to associated data. Associated
data has good data locality if it is located near one another,
because accesses are limited to a small number of pages and the
data is more likely to be in memory. Poor data locality means
associated data must be obtained from different data pages.
data point
----------------------------------
A specific point in time displayed on a performance graph where
data has been summarized every five, fifteen, or thirty minutes,
or every hour, two hours or one day.
data segment
----------------------------------
A section of memory reserved for storing a process' static and
dynamic data.
data source
----------------------------------
A data source consists of one or more data types or classes of
data in a single scopeux, scopent, or DSI log file set. For
example, the default Performance Collection Component data
source, SCOPE, is a scopeux or scopent log file set consisting of
global data.
datasources configuration file
----------------------------------
A configuration file residing in the /var/opt/OV/conf/perf/
directory. Each entry in the file represents a scopeux or DSI
data source consisting of a single log file set.
data source integration (DSI)
----------------------------------
Enables the Performance Collection Component to receive, log, and
detect alarms on data from external sources such as applications,
databases, networks, and other operating systems.
deactivated pages out
----------------------------------
Pages from deactivated process regions that are moved from memory
to the swap area. These pages are swapped out only when they are
needed by another active process.
When a process becomes reactivated, the pages are moved from the
swap area back to memory.
default
----------------------------------
An option that is automatically selected or chosen by the system.
deferred packet
----------------------------------
A deferred packet occurs when the network hardware detects that
the LAN is already in use. Rather than incur a collision, the
outbound packet transmission is delayed until the LAN is
available.
device driver
----------------------------------
A collection of kernel routines and data structures that handle
the lowest levels of input and output between a peripheral device
and executing processes. Device drivers are part of the UNIX
kernel.
device file
----------------------------------
A special file that permits direct access to a hardware device.
device swap space
----------------------------------
Space devoted to swapping.
directory name lookup cache
----------------------------------
The directory name lookup cache (DNLC) is used to cache directory
and file names. When a file is referenced by name, the name must
be broken into its components and each component's inode must be
looked up. By caching the component names, disk IOs are reduced.
disk bandwidth entitlement
----------------------------------
The percentage of disk (volume group) bandwidth guaranteed to a
particular PRM group when the total system disk bandwidth use is
at its maximum. The system administrator assigns the disk
bandwidth entitlement for each PRM group in the PRM configuration
file. The minimum entitlement for groups other than the system
group is 1%. PRM distributes unused time to other groups in
proportion to their disk bandwidth entitlements.
diskless cluster server
----------------------------------
A system that supports disk activity for diskless client nodes.
diskless file system buffer
----------------------------------
A buffer pool that is used only by the diskless server for
diskless cluster traffic.
dispatcher
----------------------------------
A module of the kernel responsible for allocating CPU resources
among several competing processes.
DSI log file
----------------------------------
A log file, created by the Performance Collection Component's DSI
(data source integration) programs, that contains self-describing
data.
empty space
----------------------------------
The difference between the maximum size of a log file and its
current size.
error (LAN)
----------------------------------
Unsuccessful transmission of a packet over a local area network
(LAN). Inbound errors are typically checksum errors. Outbound
errors are typically local hardware problems.
exec fill page
----------------------------------
When a process is 'execed' the working segments of the process
are marked as copy on write. Only when segments change are they
copied into a separate segment private to the process that is
modifying the page.
extract program
----------------------------------
The Performance Collection Component program that allows you to
extract data from raw or previously extracted log files,
summarize it, and write it to extracted log files. It also lets
you export data for use by analysis programs and other tools.
extracted log file
----------------------------------
A Performance Collection Component log file containing a user-
defined subset of data extracted (copied) from a raw or
previously extracted log file. It is formatted for optimal
access by HP Performance Manager. Extracted log files are also
used for archiving performance data.
file IO
----------------------------------
IO activity to a physical disk. It includes file system IOs,
system IOs to manage the file system, both raw and block
activity, and excludes virtual memory management IOs.
file lock
----------------------------------
A file lock guarantees exclusive access to an entire file, or
parts of a file.
file system
----------------------------------
The organization and placement of files and directories on a hard
disk. The file system includes the operating system software's
facilities for naming the files and controlling access to these
files.
file system activity
----------------------------------
Access calls (read, write, control) of file system block IO files
contained on disk.
file system swap
----------------------------------
File system space identified as available to be used as swap.
This is a lower performance method of swapping as its operations
are processed through the file system.
file table
----------------------------------
The table contains inode descriptors used by the user file
descriptors for all open files. It is set to the maximum number
of files the system can have open at any one time.
fork
----------------------------------
A system call that enables a process to duplicate itself into two
identical processes - a parent and a child process. Unlike the
vfork system call, the child process produced does not have
access to the parent process' memory and control.
free list
----------------------------------
The system keeps a list of free pages on the system. Free list
points to all the pages that are marked free.
free memory
----------------------------------
Memory not currently allocated to any user process or to the
kernel.
GlancePlus
----------------------------------

the IOs that are started in the previous interval can be
completed.

page freed
----------------------------------
When a paging daemon puts a page in the free list, it is
considered as page freed.
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.

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. Terminal 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.

log file locations, and data collection rates and calculations.
This file can be reused to define uniquely named collections of
performance counters/metrics on multiple PCs using Windows.
collection
----------------------------------
In the Performance Collection Component for Windows, a defined
set of counters/metrics that has been registered and assigned a
unique name and is based on a policy established by the
Collection Builder task.
fixed instances
----------------------------------
Permanently-named occurrences of an object type in the
Performance Collection Component for Windows. In a Collection
Builder policy, a fixed-instance policy contains metrics
(counters) that refer to a specific instance of an object and the
instance name cannot be changed when the policy is used to create
new collections for multiple PCs. Such a policy works
effectively where PCs are uniformly configured and instance names
are duplicated across the distributed application environment.
variable instances
----------------------------------
Non-specific occurrences of an object type in the Performance
Collection Component for Windows. In a Collection Builder
policy, a variable-instance policy contains metrics (counters)
that do not refer to a specific named object instance. Such a
policy enables users to select a specific instance later when
they create new collections for multiple PCs. A variable-
instance policy works effectively where PCs are configured
differently and instance names are likely to differ from PC to
PC.
sampling interval
----------------------------------
The frequency at which data values are retrieved for the
counter/metric set of any given collection in the Performance
Collection Component for Windows. These values are averaged and
logged according to the records per hour setting in the policy
file.
Windows registry
----------------------------------
A database repository for information about a computer's
configuration. It is organized in a hierarchical structure and
consists of subtrees and their keys, hives, and value entries.
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 or Hyper-V host.
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.
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.
solaris_zone
----------------------------------
A zone is a virtual operating system abstraction that provides a
protected environment in which applications run. Each application
receives a dedicated namespace in which to run, and cannot see,
monitor, or affect applications running in another zone.
Hyper-V
----------------------------------
Hyper-V role enabled Windows 2008 server.
aix_global_environment
----------------------------------
Global Environment refers to the part of the AIX operating system
that hosts workload partitions (WPARs).
aix_system_wpar
----------------------------------
A workload partition(WPAR) is a software created, virtualized OS
environment within a single AIX V6 image. Each WPAR is a secure
and isolated environment for the application it hosts. A system
WPAR is similar to a typical AIX environment.
aix_wpar
----------------------------------
A workload partition(WPAR) is a software created, virtualized OS
environment within a single AIX V6 image. Each WPAR is a secure
and isolated environment for the application it hosts. A system
WPAR is similar to a typical AIX environment.
Root partition
----------------------------------
Hyper-V role enabled Windows 2008 server that hosts Virtual
Machines. The Root partition is also represented as an instance
in BYLS class along with the Virtual Machine hosted on it.
file_cache
----------------------------------
File cache is a memory pool used by the system to stage disk IO
data for the driver.
