This topic describes how to monitor an apsaradb for RDS instance. This function provides the ability to notify you when an instance exception is detected. In addition, the system will notify you when the instance is locked due to insufficient disk capacity.


The instance must be in the mainland China region.

Background information

Monitoring and alerting are implemented through CloudMonitor. With CloudMonitor, you can configure monitored metrics and alert rules, and can associate contact groups with monitored metrics. When a monitored metric triggers an alert based on a specified alert rule, the system sends notification emails to all contacts in the contact groups associated with the monitored metric.
