Clearing Alarms

Scenarios

After an aggregated alarm is generated, it will be displayed on the Unhandled Alarms tab page. If the alarm has been handled or needs to be cleared for other reasons, you can clear the alarm on the Unhandled Alarms tab page. You can view the cleared aggregated alarm on the Historical Alarms tab page.

Precautions

Only the owner can clear current alarms.

Alarm data is retained for 31 days and will be automatically cleared, including data on the Historical Alarms tab page.

   The time from the occurrence of a fault to the recovery of the fault is called the service interruption time. COC can automatically record the service interruption time entered in Clearing alarms in the SLO interruption record of the corresponding application. The procedure is as follows:

   1. Create an SLA rule and set Trigger Type to Alarm Ticket. Choose the severity level and applications (including the aggregated alarm severity level and application).
   2. Create an SLO rule and select applications (including the aggregated alarm application).
   3. After an aggregated alarm is generated, if the severity and application match the SLA record settings, an SLA record is created.
   4. Clear the aggregated alarm, enter the fault occurrence time and fault recovery time, generate an SLO interruption record, and view the interruption record in the Operation column of the corresponding SLO rule.

6. Click OK.

   The alarm is cleared.
