Alarm Notification

Application Performance Management (APM) supports alarm notification. That is, a certain type of alarms can be sent to specified users by Short Message Service (SMS) message or email. In this way, they can identify and rectify cluster exceptions at the earliest time, preventing service loss.

You can create a maximum of 10 notification rules. If the number of notification rules reaches 10, delete unnecessary notification rules.

If you do not create any notification rule, you cannot receive alarm notifications. To view alarms, log in to the APM console and choose Alarm Center > Alarm List in the navigation pane.

Currently, APM supports creation of notification rules only for the alarms listed in Table 1.

Table 1 Alarm types

Alarm Type

Description

Probe hibernation

This alarm is generated when the probe is in hibernation state.

Collector installation alarm

This alarm is generated when the ICAgent fails to be installed, upgraded, or uninstalled, or is abnormal.

Threshold alarm

This alarm is generated when a threshold rule is triggered.

NOTE:

More types of alarms are being developed.

Creating a Notification Rule

  1. Log in to the APM console.
  2. In the navigation pane, choose Alarm Center > Notification Rules, and click Create Notification Rule.
  3. Create a topic, configure a topic policy, and add subscribers to the topic. If you have configured the topic policy, skip this step.

    APM has been interconnected with Simple Message Notification (SMN). Click Create SMN Topic and access the SMN console. On the SMN console, create a topic, and configure a topic policy by referring to Figure 1. Otherwise, alarm notifications will fail to be sent. Then, add subscribers, that is, receivers of alarm notifications (via SMS or email). For details, see Creating a Topic, Configuring Topic Policies, and Adding a Subscription in the SMN User Guide. In this way, when an exception occurs in a cluster, APM can broadcast the alarm information to the subscribers in real time.

    Figure 1 Configuring a topic policy

  4. Enter a rule name, select an alarm type (for details, see Table 1), select a created topic in 3, customize a cluster to be monitored, and click Create, as shown in Figure 2.

    After the notification rule is created, if an alarm that meets the notification rule is generated, APM automatically sends notification through SMS or email.
