This topic describes how to configure an alert rule on an ApsaraDB RDS for PostgreSQL instance. If the monitored metric meets the conditions specified in the alert rule, an alert will be sent to all of the contacts in the associated alert contact group.

Background information

The monitoring and alerts feature of ApsaraDB for RDS is implemented by using Cloud Monitor. Cloud Monitor allows you to configure metrics and alert rules. You can also specify the contact groups that are associated with specific metrics. If a metric triggers an alert based on a specified alert rule, the system sends emails to all of the contacts in the contact group that is associated with the metric.
