Checking Alarms

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.

Procedure

1. Log in to the AOM 2.0 console.
2. In the navigation pane, choose Alarm Management > Alarm List.
3. Click the Alarms tab to view the alarm information.
   1. Set a time range to view alarms. There are two methods to set a time range:

      Method 1: Use a predefined time label, such as Last hour or Last 6 hours. You can select a time range as required.

      Method 2: Specify the start time and end time (max. 31 days).

   2. Set the interval for refreshing alarms. Click and select a value from the drop-down list, such as Refresh manually or 1 minute auto refresh.
   3. Set filter criteria and click to check the alarms generated in the period. You can filter alarms by alarm severity, source, or keyword in the search box. By default, alarms are filtered by alarm severity.

      If you want to filter alarms by custom attribute, select Custom Attribute and enter "custom attribute name=custom attribute value". For example, you specify custom attribute nodeIP=192.168.0.106, the alarms of the host whose IP address is 192.168.0.106 within the specified time range will be filtered.
