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.
Prerequisites
Your RDS instance resides in a region of mainland China.
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.
