Warum und wann dieser Vorgang ausgeführt wird

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.

Prozedur

1. Navigate to All > Event Management > Administration > Event Management Properties.
2. To shorten the retention period, use the highlighted 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.
