Monitor adapter event deduplication
BMC Atrium Orchestrator provides fault tolerance by enabling an adapter on multiple peers in a grid. When multiple monitor adapters are deployed in a grid to monitor the same source, the event could possibly be captured by one or more instances of the monitor adapter. Event deduplication is achieved by caching a record of each event received for two minutes. This record is then used to detect and reject subsequent duplicate events.
Note
Deduplication requires all monitor adapter instances of a given type to have the same name.
You can change the event caching interval by setting the value in the tuning-config.xml file as follows:
<config>
<adapter-manager>
<event-digest-timeout>120000</event-digest-timeout>
</adapter-manager>
</config>
By setting the Logging Level to DEBUG for Adapter Framework you can see the following log entries in grid.log:
- When an event is discarded:
AdapterManager : Discarding duplicate event
- When an event is processed:
AdapterManager : ADAPTER_MANAGER: Submitted event to local Activity Processor.
