Heartbeat

A heartbeat is a job event that is sent at regular intervals to the application server by a user application started by an agent. User applications can be programmed to issue heartbeats by linking with the CA Workload Automation AE Software Development Kit (SDK) library. Thus, heartbeats can be used to monitor the progress of user applications. The scheduler checks that the HEARTBEAT event has occurred during the heartbeat interval specified in the heartbeat_interval attribute in a job definition. The scheduler issues the MISSING_HEARTBEAT alarm for every job that has not issued the HEARTBEAT event within the job’s heartbeat interval.

Notes:

The scheduler (not the agent) checks for heartbeats. If there is a problem between the user application and the application server, the HEARTBEAT event is not sent and the scheduler issues an alarm at the next check heart beat interval. Therefore, the HEARTBEAT event can indicate whether the network is working properly.
For more information about how to use the CA Workload Automation AE SDK APIs to develop applications, see the API Reference Guide.
