   Fault Rectification Time	This parameter is required only when Service Interrupted is set to Yes. Enter the time when the fault is rectified.

   The time from fault occurrence until service recovery is called the service interruption time. The service interruption time consumed for alarm clearance can be automatically recorded in the SLO interruption records of the corresponding application. The procedure is as follows:

   1. Create a custom SLA and set Trigger Type to Alarm. Select the severity and applications of aggregated alarms.
   2. Create an SLO and select the applications of aggregated alarms.
   3. After an aggregated alarm is generated, if the severity and applications match the SLA record settings, an SLA record is created.
   4. Clear the aggregated alarm and specify the fault occurrence time and service recovery time. An SLO interruption record is generated. You can view the interruption records in the Operation column of the corresponding SLO.

6. Click OK.

Viewing Historical Alarms

The historical alarms page displays cleared aggregated alarms. After an aggregated alarm is cleared, you can view its information and handling records on the Historical Alarms page.

The system retains alarm data for 31 days. After this period, the data will be automatically deleted.

1. Log in to COC.
2. In the navigation pane, choose Fault Management > Alarms.
3. Choose Aggregated Alarms > Historical Alarms to view the historical aggregated alarms.
4. Locate the alarm to be viewed and choose More > History Records in the Operation column to view the historical records.
