IBM Tivoli Monitoring, Version 6.3 Fix Pack 2
Check the IBM Tivoli Enterprise Console event cache
The event server rules event cache must be large enough to contain the volume of events expected at any given time.
To check the rules cache size for a running event server, run the following the IBM Tivoli Enterprise Console command:
wlsesvrcfg -c
To set this rules cache size, run the IBM Tivoli Enterprise Console command:
wsetesvrcfg -c number_of_events
For more information regarding these two commands, see the "Event server commands" in the Tivoli Enterprise Console Command and Task Reference.
If the rules event cache become full, the IBM Tivoli Enterprise Console rules engine generates a TEC_Notice event, Rule Cache full: forced cleaning, indicating that 5 percent of the events from the cache were removed. Events are removed in order by age, with the oldest events removed first allowing newer events to be processed.
When the hub monitoring server forwards a status update for a situation event previously forwarded to the Tivoli Enterprise Console event server, if the original situation event is deleted from the rules event cache, then a TEC_ITM_OM_Situation_Sync_Error event is generated to indicate that the monitoring server and the event server are out of synchronization.
When using any IBM Tivoli Enterprise Console viewer to acknowledge or close any situation event, if the situation event has been deleted from the rules event cache, the status change is not processed by the IBM Tivoli Enterprise Console rules engine. Also, the situation event update is not forwarded to the originating Tivoli Enterprise Monitoring Server. This behavior results from theIBM Tivoli Enterprise Console rules engine not processing any event status changes for any event not contained in the rules event cache. In this case, the event status change is updated only in the IBM Tivoli Enterprise Console database.
Both situations can be remedied by performing a IBM Tivoli Enterprise Console server configuration parameters analysis and performance analysis to determine the optimal configuration parameter settings and desired performance requirements. Refer to "Rule engine concepts", in the IBM IBM Tivoli Enterprise Console Rule Developer's Guide for more information.
