16.4.3 Configuring the PFM service automatic restart functionality

In the Services tree of PFM - Web Console, you can specify the property to configure the PFM service automatic restart functionality for each service. For a health check agent, use the Agent Collector service to set the automatic restart functionality for the agent. If a service does not meet any of the above prerequisite conditions, the property for this setting is not displayed. The following table lists the properties to be set for each target service.

Table 16‒21: Correspondence between the service names targeted for automatic restart and the service names to be used for setting the service properties
Supported service	Use this for setting the service property
PFM - Manager service Name Server Master Manager Master Store Correlator Trap Generator View Server	Master Manager
PFM - Agent service Agent Collector Agent Store	Agent Collector
PFM - RM service Remote Monitor Collector Remote Monitor Store	Remote Monitor Collector
Action Handler service Action Handler	Master Manager, Agent Collector, and Remote Monitor Collector^#

#:: The property settings for each of these services are shared across the same host, regardless of which program is used to make the property settings.

If there are multiple instances of PFM - Agent or PFM - RM that are of the same type and that use the same data model, you can distribute the property settings to these multiple hosts.

The following table lists the setting items for each target service.

Table 16‒22: Setting items for the service automatic restart functionality
Folder name	Property name	Description
Restart Configurations	Restart when Abnormal Status^#1	Specifies whether the service is to be restarted when the automatic restart functionality detects an `Abnormal Status`^#2. This setting is applied to all services on the host. The default is `Yes`. `Yes`: Restarts `No`: Does not restart
Restart Configurations	Restart when Single Service Running^#1	Specifies whether the service is to be restarted when the automatic restart functionality detects a `Single Service Running`^#3. This setting is applied to all services on the host. The default is `No`. `Yes`: Restarts `No`: Does not restart
`Service-name`^#4	Auto Restart	Specifies whether to use the automatic restart functionality for the target service. The default is `No`. `Yes`: Uses the automatic restart functionality. `No`: Does not use the automatic restart functionality.
	Auto Restart - Interval(Minute)	Specifies, in minutes, how often the automatic restart functionality checks the operating status when the function is used. You can specify an integer value from 1 to 1440. The default is 10 (minutes).
	Auto Restart - Repeat Limit	Specifies how many times the automatic restart functionality attempts to restart the service by using the intervals specified for Auto Restart - Interval when the functionality is used. You can specify an integer value from 1 to 10. The default is 5 (times).
	Scheduled Restart	Specifies whether to use the scheduled restart functionality for the service. The default is `No`. `Yes`: Uses the scheduled restart functionality. `No`: Does not use the scheduled restart functionality.
	Scheduled Restart - Interval	Specify an integer value from 1 to 1,000 for the interval between restarts when you use the scheduled restart functionality. The default is 1. The units for the interval are specified in the Scheduled Restart - Interval Unit.
	Scheduled Restart - Interval Unit	Specifies the restart interval units (Month/Week/Day/Hour) used by the scheduled restart functionality for restarting the service when the functionality is used. The default is Month. Month Week Day Hour
	Scheduled Restart - Origin - Year	Specifies the calendar year from which the scheduled restart functionality initiates the restart interval when the functionality is used. You can specify an integer value from 1971 to 2035^#5. The default is the current year^#6.
	Scheduled Restart - Origin - Month	Specifies the month of the year from which the scheduled restart functionality initiates the restart interval when the functionality is used. You can specify an integer value from 1 to 12^#5. The default is the current month^#6.
	Scheduled Restart - Origin - Day	Specifies the day of the month from which the scheduled restart functionality initiates the restart interval when the functionality is used. You can specify an integer value from 1 to 31^#5. The default is the current date^#6.
	Scheduled Restart - Origin - Hour	Specifies the hour of the day from which the scheduled restart functionality initiates the restart interval when the functionality is used. You can specify an integer value from 0 to 23. The default is the current hour^#6.
	Scheduled Restart - Origin - Minute	Specifies the minute of the hour from which the scheduled restart functionality initiates the restart interval when the functionality is used. You can specify an integer value from 0 to 59. The default value is the current minute^#6.

#1:: The property settings for each of these services are shared across the same host, regardless of which program is used to make the property settings.
#2:: Indicates that the Status Server service cannot obtain the status of the PFM service normally (for example, because the PFM service has ended abnormally due to an exception).
#3:: Indicates that only one of the PFM - Agent or PFM - RM services is running.
#4:: The Master Manager services shown are the PFM - Manager and Action Handler services. The Agent Collector or Remote Monitor Collector services shown are the PFM - Agent or PFM - RM and Action Handler services.
#5:: If a non-existing date (such as 2007/2/30) is specified, the last day of the month is assumed.
#6:: The date and time displayed for the property is based on the time zone setting of the host running the service.
Note:: Placing priority on continued monitoring, the PFM service automatic restart functionality restarts only specific services. The PFM - Manager services link with each other at a high level, so if only particular services are restarted, some of these links may fail. If you use the scheduled restart functionality for a PFM - Manager service, you should also set any PFM - Manager services that usually start after that service to restart. Adjust the restart time so that the services are restarted in the correct order. For details on the start sequence for PFM - Manager services, see 1.1.1 Start sequence for the entire Performance Management system. If you use the automatic restart functionality for a PFM - Manager service, after you restart the service you should select a time when there will be the least impact on system operation and stop all PFM - Manager services, and then restart them. To realize high availability of the PFM - Manager services, we recommend you use a cluster system.
