3.4.1 Overview of the health check function and the status management function

Performance Management provides a function that monitors the operating status of the monitoring agent and the host on which the monitoring agent is running. This is called the health check function. By using this function, you can confirm whether the monitoring agent is monitoring its targets correctly and whether the host of the monitoring agent is operating. If PFM - RM is used, you can confirm whether a monitored host is running. By defining alarms for the various operating statuses of the Agents and hosts, the system can issue alarm events and trigger an action such as sending an email when the health check function detects that PFM - Agent or PFM - RM is malfunctioning or detects that a host is down.

Performance Management also provides a function you can use to view the detailed operating status of Performance Management services running in the operation monitoring system. This is called the status management function.

The health check function uses the status management function to monitor the operating status of monitoring agents. For this reason, the version of the monitoring agent monitored by the health check function must support the status management function, and the status management function must be active. There are no prerequisites associated with monitoring the operating status of a host.

Important: To enable linkage with JP1/IM2, you have to first enable both the health check function and the status management function.

Figure 3‒27: Overview of checking the operating status by using the health check function (in PFM - Agent)

The health check function enables you to monitor the operating status of the host running the monitoring agent and the operating status of the monitored agent service.

Organization of this subsection

(1) Monitoring the operating status of the host running the monitoring agent
(2) Monitoring the operating status of the monitoring agent service
(3) Health check for PFM - RM

(1) Monitoring the operating status of the host running the monitoring agent

The health check function monitors the operating status of a host running PFM - Agent or PFM - RM, and the operating status of a host monitored by PFM - RM. You can check the operating status from PFM - Web Console. The following software versions support this functionality:

Version 08-11 or later of PFM - Manager and PFM - Web Console
Any version of PFM - Agent or PFM - RM

(2) Monitoring the operating status of the monitoring agent service

In addition to the operating status of the host where PFM - Agent or PFM - RM is running, and the operating status of the monitored host for PFM - RM, the health check function also monitors the operating status of Agent Collector, Remote Monitor Collector, Agent Store, and Remote Monitor Store services. Depending on the settings, the health check function can also monitor the Action Handler service on the same monitored host. You can check the results from PFM - Web Console. The following software versions support this functionality:

Version 08-11 or later of PFM - Manager and PFM - Web Console
Version 08-00 or later of PFM - Agent, or PFM - RM, with the status management function enabled

(3) Health check for PFM - RM

For PFM - RM, you can monitor the following three operating statuses:

Operating status of the host running PFM - RM
Operating status of the PFM - RM services
Operating status of the monitored host of PFM - RM

The operating status of a monitored host for PFM - RM is monitored as the operating status of the corresponding remote agent. You cannot monitor the operating status of a group agent.

You can monitor the operating status of the monitored host for PFM - RM, regardless of whether you set the health check function to the host monitoring level or the service monitoring level. However, if this function is set to the service monitoring level, the operating status of the monitored host for PFM - RM varies, depending on the status of the Remote Monitor Store or Action Handler service. If you want to monitor the operating status of the monitored host for PFM - RM, you must enable the status management function of PFM - RM, even when setting the health check function to the host monitoring level.

For details about monitoring the operating status of the host monitored by PFM -RM, see the chapter that describes detecting problems in Performance Management in the JP1/Performance Management User's Guide.
