The HP Operations agent contains new features, feature enhancements, and other changes.
The HP Operations agent 11.00 contains these new features:
This version of the HP Operations agent combines the features of the HP Operations agent, HP Performance Agent, and HP GlancePlus together under one installer. With the newly introduced HP Operations OS Inst Adv SW LTU, you can use the features that were available with the HP Performance Agent.
This version of the HP Operations agent enables you to view real-time system performance data with the help of the Diagnostic view of HP Performance Manager 9.00.
With the Diagnostic view, you can view the real-time data from all types of agent nodes (Windows as well as UNIX/Linux).
This version of the HP Operations agent introduces a new licensing tool and a collection of new LTUs. The new licensing tool—oalicense—helps you enable an LTU (or a combination of LTUs) of your choice on a node.
Because this version of the agent combines functional components of the HP Performance Agent and HP GlancePlus, you can enable different modes of the product with different LTUs. For example, you can enable the agent to monitor only the system performance metrics (without enabling the operational components like the message agent or action agent), or you can enable the real-time metric access component with all other operational components of the HP Operations agent.
You can monitor MIB objects with different community strings. The new configuration variable— SNMP_COMMUNITY_LIST—enables you to configure the agent to query MIB objects with different community strings. You can also monitor child OIDs of a monitored MIB object.
The Logfile Encapsulator component of the HP Operations agent can monitor the Windows Applications and Services event logs on Windows Vista, Windows 7, and Windows Server 2008.
This version of the agent periodically stores the values of monitored objects and session variables to preserve the values in the event of an interruption or failure.
For more information, see the Components of the HP Operations Agent section in the HP Operations Agent Concepts Guide.
For agentless monitoring of remote nodes, you can use this version of the HP Operations agent to remotely monitor IPv6-only nodes by using the monitor agent, event interceptor, or WMI interceptor.
On a hyper-threading-enabled system, the HP Operations agent 11.00 provides you with the option to log key CPU-related metrics (all CPU metrics on HP-UX; global CPU metrics on other platforms) that are normalized against the number of active cores. Without this option, the CPU-related metrics are normalized against the number of hardware threads on the system. For more information, see the HP Operations Agent User Guide.
The HP Operations agent 11.00 contains these changes:
The HP Operations agent runs in these HP Operations Manager (HPOM) environments:
Installation requirements, as well as instructions for installing the HP Operations agent, are documented in the Installation Guide for HP Operations Agent provided in PDF (.pdf) format.

The following items (identified by reference number) are fixed in the current software release. To display details about each software fix, click the reference number. To hide details, click again.
QCCR1A88900: Since the GBL_CPU_ENTL metric belongs to the configuration metric class, you cannot perform the drilldown operation on the metric when viewed from the HP Performance Manager graphs.
| PROBLEM: | Since the GBL_CPU_ENTL metric belongs to the configuration metric class, you cannot perform the drilldown operation on the metric when viewed from the HP Performance Manager graphs. |
| FIX: | The metric now belongs to the Global metric class, and therefore, you can perform the drilldown operation on it. |
QCCR1A71293: Option to set the data directory while installing the agent
| PROBLEM: | The installer program for the agent does not allow you to set a non-default data directory. |
| FIX: | The -data_dir parameter in the oainstall or oasetup program enables you to set a non-default data directory. |
QCCR1A71283: On the Windows node, agent installation is very slow
| PROBLEM: | On Windows nodes, the remote installation of the agent takes up to 15 minutes. |
| FIX: | This version of the agent includes fewer number of packages; this results in shorter installation time. |
QCCR1A70977, QCCR1A69498, and QCCR1A69698: When the node or the management server restarts, the state information of a monitor policy is lost
| PROBLEM: | The HP Operations agent cannot retain the state information of monitored objects when you restart the node or the management server. |
| FIX: | The persistence of monitored objects feature, available with this version of the agent, resolves this problem. |
QCCR1A69814: Logging verbosity for the agent installation
| PROBLEM: | The installation log file for the HP Operations agent is not verbose. |
| FIX: | The agent installer program is now enhanced to log verbose data into the log file. The installation log file (oainstall.log) is available in the following directory on the node: On Windows: %ovdatadir%log On UNIX/Linux: /var/opt/OV/log |
QCCR1A69468: The <$x>,<$X>, and <$@> variables in an SNMP-interceptor policy do not work on the agent without Network Node Manager (NNM)
| PROBLEM: | The <$x>,<$X>, and <$@> variables in an SNMP-interceptor policy do not return correct values when NNM's postmaster daemon is not present. |
| FIX: | With this version of the agent, the <$x>,<$X>, and <$@> variables work without NNM. |
This release contains certain unresolved problems, some limitations, and there are workaround to help solve certain problems.
QCCR1A110990: Remote installation of the agent on a Solaris SPARC node from HPOM on UNIX/Linux 9.x fails.
| PROBLEM: | Remote installation of the agent on a Solaris SPARC node from HPOM on UNIX/Linux 9.x fails. |
| WORKAROUND: | Obtain the necessary hotfix from HP Support. |
QCCR1A123980: The disk space check fails on HP-UX fails although adequate disk space is available for the installation and data directories.
| PROBLEM: | The disk space check fails and one of the following error messages appears in the command-line console: Not enough disk space on /opt Not enough disk space on /var |
| WORKAROUND: | Obtain the necessary hotfix from HP Support. |
QCCR1A109288: Remote Installation of the HP Operations agent 11.00 on a Solaris SPARC system from HPOM for UNIX 8.x (HP-UX, Itanium) fails.
| PROBLEM: | Remote Installation of the HP Operations agent 11.00 on a Solaris SPARC system from HPOM for UNIX 8.x (HP-UX, Itanium) fails with the following error: Failed to successfully install OVO on system $s! $s |
| WORKAROUND: | Obtain the necessary hotfix from HP Support. |

| PROBLEM: | Deployment of the HP Operations Agent 11.00 on an HPOM for UNIX 8.x (HP-UX) management server fails due to the operating system version check error. |
| WORKAROUND: | Obtain the necessary hotfix from HP Support. |
QCCR1A115181: Frequent configuration of the monitor agent results in high memory consumption.
| PROBLEM: | Frequent configuration of the monitor agent (which includes adding, removing, enabling, or disabling measurement threshold policies on the node) results in high memory consumption; the monitor agent can even stop functioning. |
| WORKAROUND: | Restart the monitor agent by running the following command: ovc -restart opcmona |
QCCR1A113275: Significant memory growth observed when the HP Operations agent monitors Windows Event Logs.
| PROBLEM: | On the Windows Vista, Windows 7, Windows 2008, and Windows Server 2008 R2 nodes, significant memory consumption by opcle is observed when you use the Logfile Encapsulator to monitor Windows Event Logs. |
| WORKAROUND: | Re-initialize the Event Logs. |
QCCR1A113731: The Logfile Encapsulator cannot handle some events
| PROBLEM: | On the Windows Vista, Windows 7, Windows 2008, and Windows Server 2008 R2 nodes, the Logfile Encapsulator cannot handle a few events. |
| WORKAROUND: | This problem occurs when an event publisher does not have its even data registered. When the Logfile Encapsulator cannot read five consecutive events, the HP Operations agent sends a warning message to the HPOM message browser. This is resolved when the event publisher has its event data registered. |
QCCR1A112223: The Category field for the message triggered by the Logfile Encapsulator appears as 'null.'
| PROBLEM: | On the Windows Vista, Windows 7, Windows 2008, and Windows Server 2008 R2 nodes, where the locale is set to a language other than English, Japanese, Simplified Chinese, or Spanish, the Logfile Encapsulator sends the value null to the HPOM console for the Task Category for the events with the event ID 0. |
| WORKAROUND: | None |
QCCR1A103637: If you monitor the Windows Event Logs, the svchost process may consume more than 50% of CPU.
| PROBLEM: | On the Windows Vista, Windows 7, Windows 2008, and Windows Server 2008 R2 nodes, the svchost process may consume more than 50% of CPU when you use the Logfile Encapsulator to monitor Windows Event Logs. |
| WORKAROUND: | None |
QCCR1A101511: Status details of some processes are not localized.
| PROBLEM: | On a system, where the localized agent is supported, the opcagt command shows details of some processes (like scope, midaemon, perfalarm, ttd, and perfd) in English. |
| WORKAROUND: | None |
QCCR1A107286: Multiple entries for the HP Software HTTP Communication and HP Software Process Control components appear on the AIX 5.3 node.
| PROBLEM: | After installing the HP Operations agent 11.00 on an AIX 5.3 node where the HP Operations agent 8.53 or HP Performance Agent 4.70 was already installed, multiple entries for the HP Software HTTP Communication and HP Software Process Control components appear in the list of installed packages when you run the lslpp -l command. |
| WORKAROUND: | None |
QCCR1A113732: On a multi-socket Linux system, the HP Operations agent determines the number of active cores incorrectly.
| PROBLEM: |
On a multi-socket Linux system, the HP Operations agent determines the number of active cores incorrectly. As a result, the agent shows incorrect values for the GBL_CPU_* metrics when the core-based normalization is enabled. |
| WORKAROUND: | None |
QCCR1A114346: Inside shared WPARs, if you upgrade the agent to the version 11.00 (from the HP Operations agent 8.60 or HP Performance Agent 5.00), the scopeux and opcmsgi processes do not start running automatically.
| PROBLEM: | Inside shared WPARs, if you upgrade the agent to the version 11.00 (from the HP Operations agent 8.60 or HP Performance Agent 5.00), the scopeux and opcmsgi processes do not start running automatically. |
| WORKAROUND: | None |
QCCR1A113594: On vMA, scope fails to start viserver.
| PROBLEM: | On vMA, viserver does not start if the .viserver.lock file is present in the /var/opt/perf directory. |
| WORKAROUND: | Go to the status.scope file and check if the following error exists: - Thread[main,5,main] /var/opt/perf/.viserver.lock already exists. Another instance of viserver may be running. Exiting!If viserver is not actively running and file /var/opt/perf/.viserver.lock is found, delete the file and restart. If the above error exists, delete the .viserver.lock file from the directory /var/opt/perf. |
QCCR1A110366: PROC_CPU_SYSCALL_UTIL is incorrectly reported by the HP Operations agent.
| PROBLEM: | On HP-UX, the HP Operations agent reports incorrect values for the metric PROC_CPU_SYSCALL_UTIL. |
| WORKAROUND: | None |
QCCR1A115613: On Windows, the Logfile Encapsulator stops working when Logfile Entry policies include variables in the %variable_name% format in the log file path.
