3.4.3 Using the monitoring results obtained from the status management function

(1) When the status management function is enabled

When the status management function is enabled, all services that run on PFM - Manager and PFM - Base register their status in a status file. The system administrator can then learn the status of each service by using the status management service (Status Server service) to check the contents of this file. To check the contents of the status file, you execute an operation command (the jpctool service list).

For details about how to configure the status management function, see the chapter that describes detecting problems in Performance Management in the JP1/Performance Management User's Guide.

(2) When the status management function is disabled

If the status management function is disabled, PFM - Manager determines the service status based on whether attempts to communicate with PFM - Agent or PFM - RM yields a response. In addition, PFM - Manager centrally manages network information such as the IP addresses and port numbers for PFM - Agent or PFM - RM. Therefore, the service status cannot be checked if communication with PFM - Manager is not possible because an error has occurred, the service is starting, or for some other reason the status also cannot be checked when PFM - Agent or PFM - RM is running in standalone mode.

If the status management function is disabled, you might be unable to check the status of a service that is starting or stopping when you execute the jpctool service list command. If it is necessary to check the service status, enable the status management function. The following figure shows an example of checking the status of Performance Management with the status management function disabled.
