9.4 Settings for automatic execution of processes by management events
This section describes settings for automatic execution of processes by Management events.
Management events are used to notify Management Server of failure, resource depletion, and other phenomena that occurred on the J2EE server or batch server in the management domain. All messages that are output by the J2EE server or batch server during its operation can be used as triggers to issue Management events. By defining the operations, to be performed when a Management event is notified, in the Management Server, the action can be executed automatically when the management event occurs. This action is called a management action.
For example, if the resource depletion monitoring functionality is used to monitor memory usage, a Management event can be issued before Full GC occurs by using a message that is output as an alert when a threshold is exceeded. On the J2EE server or batch server, a Management action that shuts down and restarts the services can be defined. In this case, the defined action can be automatically performed, upon detection of a symptom that can trigger Full GC, to prevent the processing of a request from being stopped.
By detecting events such as a failure using a Management event and defining a corresponding action for the Management event as a Management action, you can automatically execute the processes for the occurred events such as actions for preventing failures.
