ApsaraDB RDS:Manage alerts

How it works

CloudMonitor collects metrics from your RDS instances and evaluates them against alert rules. When a metric meets the conditions in a rule, CloudMonitor sends email notifications to all contacts in the associated alert contact group.

To receive alerts, create an alert contact group and assign it to your alert rules.

For other database engines, see:

• Configure an alert rule for an ApsaraDB RDS for SQL Server instance

• Configure an alert rule for an ApsaraDB RDS for PostgreSQL instance

• Configure an alert rule for an ApsaraDB RDS for MariaDB instance

Prerequisites

FAQ

Q: Does ApsaraDB RDS support backup failure alerts? How can I check backup task status?

A: ApsaraDB RDS does not support configuring backup failure alerts directly. The RDS metrics provided by Cloud Monitor do not include a backup failure metric. To check the status of backup tasks, do one of the following:

• View the backup task list and status on the Backup and Restoration page of the ApsaraDB RDS console.

• Call the DescribeBackupTasks API operation to query the backup task list and status.
