You can create alarm policies to trigger alarms and send alarm notifications when the TencentDB instance status changes. The created alarm policies can determine whether an alarm needs to be triggered according to the difference between the monitoring metric value and the given threshold at intervals.
You can take appropriate precautionary or remedial measures in a timely manner when the alarm is triggered by changed product status. Therefore, properly created alarm policies can help you improve the robustness and reliability of your applications. For more information on alarms, see Creating Alarm Policy in Cloud Monitor.
To send an alarm for a specific status of a product, you need to create an alarm policy at first. An alarm policy is composed of three compulsory components, that is, the name, type and alarm triggering conditions. Each alarm policy is a set of alarm triggering conditions with the logical relationship "or", that is, as long as one of the conditions is met, an alarm will be triggered. The alarm will be sent to all users associated with the alarm policy. Upon receiving the alarm, the user can view the alarm and take appropriate actions in time.
Make sure that you have set the default alarm recipient; otherwise, the default alarm policy of TencentDB won't be able to send notifications.
After the alarm policy is created, you can associate alarm objects with it. When an alarm object satisfies an alarm trigger condition, an alarm notification will be sent.
