ApsaraDB RDS integrates with CloudMonitor to notify you when key metrics cross thresholds or when your instance is locked due to insufficient storage. Notifications are sent by email to all contacts in your alert contact group.
Background information
The monitoring and alerting feature of ApsaraDB RDS is implemented by using CloudMonitor. CloudMonitor allows you to configure metrics and alert rules. When a condition specified for an alert rule is met, CloudMonitor sends alert notifications to all alert contacts in your alert contact group by sending emails. You can manage the alert contact group that corresponds to a monitoring metric. When an alert is triggered, the system can notify alert contacts in the alert contact group at the earliest opportunity.
Turn on Initiative Alert
Initiative Alert is a one-click option that instantly activates an alerting mechanism for key metrics on your RDS instance. Use this option if you want alert coverage without configuring individual rules.
For details on what Initiative Alert covers, see Enable the initiative alert feature.

Create an alert rule
Creating an alert rule requires two steps in the CloudMonitor console: setting up an alert contact group (who receives notifications) and defining the alert rule (which metric and threshold to monitor).
CloudMonitor can also monitor resources automatically based on tags. See Monitor resources based on tags.
