Checking Alarms

Alarms are reported when AOM or an external service is abnormal or may cause exceptions. You need to take measures accordingly. Otherwise, service exceptions may occur. The Alarms tab page allows you to query and handle alarms, so that you can quickly detect, locate, and rectify faults.

Function Introduction

The alarm list provides the following key functions:

  • Alarm list: View alarm information by alarm severity in a graph.
  • Advanced filtering: You can filter alarms by alarm severity, source, or keyword in the search box. By default, alarms are filtered by alarm severity.
  • Alarm clearance: Clear alarms one by one or in batches.
  • Alarm details: View the alarm object and handling suggestions in the alarm details. Handling suggestions are provided for all alarms.

  2. In the navigation pane, choose Alarm Management > Alarm List.
  3. Click the Alarms tab to view the alarm information.
