This topic describes how to configure an alert rule for an ApsaraDB RDS for MariaDB instance. ApsaraDB RDS provides the monitoring and alerting feature. If exceptions are detected on your RDS instance or if your RDS instance is locked due to insufficient storage capacity, the system sends notifications to you.
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
If you turn on Initiative Alert, an alerting mechanism is quickly created for your RDS instance. This allows you to obtain the exceptions to key metrics at the earliest opportunity. For more information, see Enable the initiative alert feature.
