This topic describes how to configure alert rules for an ApsaraDB RDS for MariaDB TX instance. ApsaraDB for RDS offers the monitoring and alerting feature. If exceptions are detected in your RDS instance or if your RDS instance is locked due to low disk capacity, the system can send notifications to you.

Background information

The monitoring and alerting feature of ApsaraDB RDS is implemented by using Cloud Monitor. Cloud Monitor allows you to configure metrics and alert rules. You can also associate alert groups with metrics. If a metric meets the conditions that are specified in an alert rule, alerts are sent as emails to all the contacts in the alert group that is associated with the metric.

Enable the initiative alert feature

The initiative alert feature allows you to establish an alert system for multiple metrics in RDS. An alert notification is sent if an exception of a key metric occurs. You can then handle the exception at the earliest opportunity. For more information, see Enable the initiative alert feature.

  2. In the left-side navigation pane, click Monitoring and Alerts.
