Insight events generated by agents are persistent in the database tables A purge job runs to purge data based on the EventStoreRetentionPeriod
attribute in InsightConfigMbean attribute comparing the CREATION_DATE
column. The default value is -1, which means the purge job will always be running in background and deletes events once they are processed. Once a non-zero value is configured in the mBean, a server restart is required for the purge job to pick up the configured value. Any events older than the retention period (comparing CREATION_DATE
column will be deleted.
You can purge only successful events.
