You can create an alarm to warn you of the status change of a cloud product and send related messages. The created alarm determines whether an alarm notification needs to be triggered according to the comparison results between a monitoring metric and a specific threshold at every interval.
You can take appropriate precautionary or remedial measures in a timely manner when the alarm is triggered. Therefore, properly created alarms can help you improve the robustness and reliability of your applications. For more information on alarms, please see Alarm Configuration in Cloud Monitor.
If you want to send an alarm message for a specific status of a product, you need to create an alarm policy first, which is composed of three mandatory components: name, type, and alarm trigger condition. Each alarm policy is a set of alarm trigger conditions in the logical OR relationship, i.e., as long as one of the trigger conditions is satisfied, the alarm will be triggered. The alarm notification will be sent to all users associated with the alarm policy. They can take appropriate actions after receiving the notification.
Make sure that you have set the default alarm recipient; otherwise, the default alarm policy of TencentDB won't be able to send notifications.
Directions
