Creating an Event Alarm Rule

You can set event conditions for services by setting event alarm rules. When a service changes and resource data meets the event conditions, an event alarm is generated.

Precautions

If you want to receive notifications by email or SMS message when the resource data of a service meets the event condition, set an alarm action policy according to Creating an Alarm Action Policy.

Procedure

  1. Log in to the AOM console. In the navigation pane, choose Alarm Center > Alarm Rules. Then, click Create Alarm Rule in the upper right corner.
  2. Set an event alarm rule.

    1. Set basic information such as the rule name and description.
      Figure 1 Setting basic information
    2. Set details about the rule.
      1. Set Rule Type to Event alarm.
      2. Set the alarm source, trigger object, and trigger policy.

        Parameter

        Description

        Alarm Source

        Name of the service for which an event alarm is reported. You can select a service from the service list.

        Trigger Object

        Select criteria to filter service events. You can select Notification Type, Event Name, Alarm Severity, Custom Attributes, Namespace, or Cluster Name as the filter criterion. One or more criteria can be selected.

        Trigger Policy

        Policy for triggering event alarms.

    3. Set an alarm notification policy. There are two alarm notification modes.
      • Direct alarm reporting: An alarm is directly sent when the alarm condition is met.

        You need to configure whether to enable an alarm action policy. After this function is enabled, the system sends alarm notifications based on the associated SMN topic and message template. If the existing alarm action policies cannot meet the requirements, click Create Policy to add one. For details about how to set an alarm action policy, see Creating an Alarm Action Policy.

      • Alarm noise reduction: Alarms are sent only after being processed based on alarm action policies, preventing alarm storms.

        Select a grouping rule to reduce alarm noise. If existing grouping rules cannot meet your requirements, click Create Grouping Rule to create one. For details, see Grouping Rules.

  3. Click Create Now. An event alarm rule is created, as shown in Figure 5.

    This rule monitors critical alarm events of AOM. When the AOM resources meet the preset event alarm condition, critical alarms are generated on the alarm page.

    In the navigation pane, choose Alarm Center > Alarm List to view the alarm. When a service event meets the preset notification policy, the system sends an alarm notification to the specified personnel by email, SMS, or WeCom.
