Understanding Pruned Events

Pruned events are removed from the main events database table and placed in a separate events database, enabling you to reduce the size of the main database while still keeping older events accessible on the ICPAM system. Pruned events are not visible in Events & Alarms, but are included in reports. Pruned events can also be included in system backups.

Tip            See the Creating Reports from Pruned Events 

The following conditions apply when pruning events:

·         Pruning will fail if any events or alarms have pending actions (such as an automated rule). Select the Clean up queues command to clear actions for old events or alarms.

·         Pruning deletes events from the live events database only if they were copied to the historical events database.

·         Alarms are deleted only if all alarm duplicates and annotations are past the live events time.

Tip            The pruning process can impact system performance. Schedule pruning to occur during off-peak hours.
