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.


  1. Navigate to System Maintenance > Table Cleanup.
  2. Shorten the retention period (in seconds) for records of the following tables:
    • Alerts [em_alert]
    • Alert History [em_alert_history]
    • Impact Status [em_impact_status]
