About this task
If records are older than 90 days, by default they are purged. If records are retained for a longer period, larger volumes of data are stored, and performance may be impacted. The data cleanup is done by two jobs: Event Management - Clean Alert History Table and Event Management - Clean Impact Status Table.
Procedure
Navigate to All > Event Management > Administration > Event Management Properties.
To shorten the retention period, use the highlighted properties.
Event Management Properties
- Clean alert history and impact status tables
Schedule jobs to mark and remove old alert records in the Alert History [em_alert_history] and Impact Status [em_impact_status] tables, to prevent the tables from becoming overloaded with data.
