What is automatic deletion of correlated alarms?

Overview

You can configure the NFM-P to automatically delete correlated alarms when the correlating alarm is deleted, as described in How do I configure alarm severity and deletion behavior?. You can also configure NFM-P alarm settings to specify whether a user notification is displayed before you delete one or more correlated alarms.

To prevent cleared alarms from persisting in the NFM-P, alarm severity is not promoted by alarm correlation when you choose one of the following options for automatic alarm deletion. The options disable the correlation of alarm severity in the NFM-P network.

• Disable Automatic Alarm Deletion

• Delete Alarms when Acknowledged

• Delete Alarms when Cleared and Acknowledged

Note: A correlated alarm is not deleted after the deletion of the correlating alarm if there is another correlating alarm associated with the correlated alarm. Therefore, the number of correlated alarms that are automatically deleted may be less than the number in the warning notification to a GUI operator.
