You can configure alert rules for system events of ApsaraDB RDS in the CloudMonitor
console. After you configure alert rules, CloudMonitor generates alerts when the specified
thresholds are reached or events are detected. This helps you make business decisions.
Background information
CloudMonitor is a service that monitors Internet applications and Alibaba Cloud resources. You
can configure CloudMonitor to notify you of system exceptions. Then, you can automate
the event handling process based on alert notifications. CloudMonitor supports the
following notification methods:
Send alert notifications by using emails or DingTalk chatbots.
Push events to Message Service (MNS), Function Compute, Log Service, or a specified
callback URL. This allows you to automate the event handling process.
CloudMonitor sends notifications to alert contacts in contact groups. You must create
an alert contact and a contact group and add the alert contact to the contact group.
In the left-side navigation pane, choose Alerts > Alert Rules.
On the page that appears, click the Event Alert tab. On the Event Alert tab, click Create Event Alert.
In the panel that appears, configure the parameters to create an alert rule.
