   3. Configure alarm notifications.

      Notification Object	The name of the topic the alarm notification is to be sent to. If you enable alarm notification, you need to select a topic. If no desirable topics are available, create one and subscribe to it first. For details about how to create a topic, see the Simple Message Notification User Guide.	-
      Trigger Condition	The condition for triggering the alarm notification. You can select Generated alarm, Cleared alarm, or both.	-

   4. Click Create.

After the alarm rule is created, if the metric data reaches the specified threshold or a CBR event happens, Cloud Eye immediately informs you that an exception has occurred. For details, see the Cloud Eye User Guide.
