This topic describes how to add alert rules.
Procedure
Go to the Cluster Workspace page. In the left-side navigation pane, click Monitoring.
In the upper-right corner of the page, click Add Alert Rule.
Set associated resources.
Product: Enter OceanBase Database by default.
Resource Range: Select All Resources or Cluster.
If you select All Resources, the system sends alert notifications if any metric of any instance of the specified service reaches the specified threshold.
If you select Cluster and specify an instance, the system sends alert notifications only when a metric of the instance reaches the specified threshold. To create an alert rule for a group, go to the group resource page.
Set the alert rule.
Enter a rule name. Make sure that it is different from the names of existing rules.
Specify the rule information, such as the description, cycle, duration, average value, and threshold.
You can click Add Alert Rule to add multiple rules.
Specify Mute For by selecting from the drop-down list. It specifies the interval for sending alert notifications before the alert is cleared.
Specify the validity period by selecting from the drop-down lists.
Select a notification method.
Select recipients.
Select existing contacts.
Create a contact group.
Specify the alert notification method, specify whether to enable auto scaling and the log service, and add email remarks.
Set Alert Callback to a URL accessible over the Internet. CloudMonitor pushes alert information to the URL through POST requests.
Click OK.
