Adding an Alarm-wide Suppression

Temporarily stop notifications from an alarm by applying a suppression. For example, use a suppression to suspend alarm notifications during system maintenance. Each suppression applies to a single alarm. In the Console, you can apply one definition of a suppression to many alarms. The result is an individual suppression for each alarm.

Important

Only one alarm-wide suppression  can be configured per alarm. Any existing alarm-wide suppression for an alarm is overwritten when you apply a new suppression.

To add a dimension-specific suppression, see Adding a Dimension-Specific Alarm Suppression.

Expired suppressions continue to be listed on pages in the Console. A suppression expires when the end time passes.

For alarm troubleshooting, see Troubleshooting Alarms.

To remove an alarm-wide suppression, see Removing an Alarm-wide Suppression.

      2. Click Actions and then select Add suppressions.
      3. In the Suppress Alarms dialog box, provide the following values:

    oci monitoring alarm update --suppression <file_or_text> --alarm-id <alarm_OCID>

    For a complete list of parameters and values for CLI commands, see the Command Line Reference for Monitoring.

  • Run the UpdateAlarm operation to add an alarm-wide suppression.
