Enabling Event Alarms
Last updated: 2025-11-20 09:44:42
TencentDB for PostgreSQL supports the event alarm feature. If the user sets event alarms related to CPU elastic scaling and configures alarm notifications, when events such as scale-out triggering, scale-out failure, and scale-in are detected, event alarm notifications will be sent through various optional channels to the user. This document introduces how to set up event alarms related to CPU elastic scaling.
Scenarios
Users can create event alarms to trigger alarms and send related messages when status changes (such as CPU elastic scale-out success, CPU elastic scale-out failure, and CPU elastic scale-in success) occur after the elastic scaling feature is enabled in TencentDB for PostgreSQL.
Operation Steps
Creating an Alarm Policy
1. Log in to the Tencent Cloud Observability Platform console, and choose Alarm Management > Alarm Configuration in the left sidebar.
2. On the alarm policy page, select Cloud Product Monitoring as the monitoring type and click Create Policy.
3. On the policy creation page, complete the settings for basic information, alarm rules, and alarm notifications.
Policy Type: Choose Cloud Database > PostgreSQL.
Alarm Object: You can find the object instance that needs to be associated by selecting the region where the object is located or searching for the instance ID of the object.
Trigger Condition: Find event alarms, click Add Event, and add CPU performance scale-out, CPU performance scale-out failure, and CPU performance scale-in alarm events respectively.
Configure alarm notification: You can select a preset or user-defined notification template. For custom notification templates, see Creating Notification Template.
Select a system preset template.
Create a template.
4. After confirmation, click Complete.
Associating an Alarm Object
After creating an alarm policy, you can also associate it with other alarm objects (instances that require alarms related to the CPU performance scaling). When the object meets the alarm trigger condition, an alarm will be sent.
1. On the Alarm Policy page, click the Policy Name to enter the alarm policy management page.
2. On the Alarm Object section of the alarm policy management page, click Add Object.
3. In the pop-up dialog box, select the alarm object to be associated with, and click OK to associate the alarm object.
