Using EventBroker to Monitor Your Application
The BEA Tuxedo EventBroker monitors a running application for events (for example, a state change in a MIB object, such as the transition of a client from active to inactive). When the EventBroker detects an event, it reports or posts the event, and then notifies relevant subscribers that the event has occurred. You can be informed automatically when events occur in the MIB by receiving FML data buffers representing MIB objects. To post the event and report it to subscribers, the EventBroker uses the tppost(3c) function. Both administrators and application processes can subscribe to events.
The EventBroker recognizes over 100 meaningful state transitions to a MIB object as system events. A posting for a system event includes the current MIB representation of the object on which the event occurred, and some event-specific fields that identify the event that occurred. For example, if a machine is partitioned, an event is posted with the following:
To use the EventBroker, you simply subscribe to system events.
