An Alert Rule activates an alert when a Monitored Asset included in the Alert Rule enters an Alarm state. You may need to disable an Alert Rule during a planned outage or other temporary condition to stop alerts from being generated. An Alert Rule can also be deleted when alerts are no longer required to be generated. You must be assigned to an Admin role to disable or delete an Alert Rule.
Go to Monitoring > Alert Rules.
From the list, select the Name of the Alert Rule. Its profile is displayed.
Select Show Advanced Options.
Deselect the Enable Alert Rule checkbox.
When alerts are to resume, return to the Alert Rule and select the Enable Alert Rule checkbox and save the update.
