Creating an AOM Alarm Notification Rule

You can create an alarm notification rule and associate it with an SMN topic and a message template. If the log/resource/metric data meets the alarm condition, the system sends an alarm notification based on the associated SMN topic and message template.

Prerequisites

You have created a topic. For details, see Creating a Topic.
You have configured a topic policy. For details, see Configuring Topic Policies.
You have added a subscriber (that is, an email or SMS message recipient) for the topic. For details, see Adding a Subscription to a Topic
To obtain SMN topics when creating a notification rule, you must obtain the smn:topic:list permission in advance. For details, see SMN Permissions.

Constraints

You can create up to 1,000 alarm notification rules. If this limit has been reached, delete unnecessary rules.
