Automating housekeeping tasks

You can automate housekeeping tasks using scripts provided.

Setting events to expire automatically
The hk_set_expiretime trigger sets the default expiry time for all events where it is not already set. The default values are set in the master.properties table.
Reducing severity of events automatically
The hk_de_escalate_events trigger gradually reduces the severity of events over time. The default values are set in the master.properties table.
Preventing core tables to grow beyond limit
The hk_row_counter trigger monitors the following core tables to prevent them exceeding the predefined size: alerts.status, alerts.journal, and alerts.details. The trigger periodically checks the size of the tables and deletes data from any of the tables where the set threshold is exceeded. As a result, the tables do not grow beyond the set number of rows.
