BES - What is the EventDaemon?

Last Updated: Jan 09, 2015 03:16PM UTC
The EventDaemon is a Java client of the AlertServer that provides synchronisation between alerts generated by the Business Enterprise Server and any connected third party application (e.g. HP Network Node Manager) by acting as the intermediary between the AlertServer and the third party application. The EventDaemon sends action events to the connecting program in a message channel for forwarding to the third party application. The action events are used to update the alerts or events in the third party application to reflect the same state as in BES (e.g. if an event is closed in BES, its reciprocal alert is closed in the third party application).

The status of the EventDaemon can be monitored by:
-          Viewing statistics.
-          Enabling and disabling debug mode for the EventDaemon and its client connections.
-          Temporarily modifying EventDaemon queue size alerts.
-          Viewing current connections to the EventDaemon.
-          Viewing alerts (in XML format) currently stored by the EventDaemon.
By issuing a telnet to the BES server on port 40002 (default), it is possible to interact with EventDaemon.

Log: $PPLOG/POWERpack_Log

telnet to the EventDaemon:
telnet localhost 40002
