Setting ECS alarm rules allows you to customize the monitored objects and notification policies and determine the running statuses of your ECSs at any time.
This section describes how to set ECS alarm rules, including alarm rule names, monitoring objects, monitoring metrics, alarm thresholds, monitoring periods, and notifications.
The following operations use modifying an existing alarm rule as an example.
After an alarm rule is modified, the system automatically notifies you of an alarm when the alarm complies with the alarm rule is generated.
