In the DDS, you can configure an alarm policy for monitoring metrics. The policy is enabled by default for activated instances. You can modify the alarm thresholds of the server and instances.
Customizing Alarm Threshold Configuration
Log in to the DDS management console.
Click the Alarm Center menu, and then click the Alarm Configuration menu. For some resource pools, the menu is displayed as Alarm Rules.
On the Alarm Configuration page, you can view Server Alarm Configuration and Database Alarm Configuration.
On the Alarm Configuration page, click Server Alarm Configuration or Database Alarm Configuration to customize the thresholds for each monitoring metric.
When an alarm that meets the rules is generated, an alarm notification is generated on the alarm list page, and the alarm record is recorded on the alarm history page.
