Adjust how long the SystemLink Enterprise Alarm Service keeps your alarms.

Introduced in September 2024

The Alarm Service has the following default settings for retaining active and inactive alarms.

  • Active alarms: The Alarm Service deletes active alarms that you have not updated in 90 days.
  • Inactive alarms: The Alarm Service deletes inactive alarms after 30 days.

To change the alarm retention settings, complete the following steps.

Note Retaining too many alarms can degrade performance.
  1. Open the systemlink-values.yaml file.
  2. Complete the following steps based on your goal.
    OptionDescription
    Configure retention for active alarms.
    1. Modify the value of alarmservice.database.activeAlarmCleanup.interval.
    2. To delete only active alarms with CLEAR as the most recent transition, set alarmservice.database.activeAlarmCleanup.onlyCleanUpClearActiveAlarms to true.
    Configure retention for inactive alarms. Modify the value of alarmservice.database.inactiveAlarmCleanupInterval.
  3. Optional: To retain alarms permanently, you must specify the nialarminstancePermanent keyword in the keywords list when creating the alarm.
    Note

    Use this setting sparingly. The Alarm Service limits the number of alarms you can create. If you retain too many alarms indefinitely, you might reach the Alarm Service alarm limit.
