Tencent Cloud provides the Cloud Monitor service for all users by default; therefore, you do not need to manually activate it. Cloud Monitor will start collecting monitoring data only after a Tencent Cloud product is used.

Getting Monitoring Data

Obtaining method

The CKafka Console provides a dedicated tab for viewing monitoring data.
Monitoring data in the CKafka Console can be displayed by instance or topic. In the console, you can view monitoring data of CKafka instances and topics such as production traffic, consumption traffic, and number of retained messages. In addition, you can query the data within any custom time period. The specific steps are as follows:

1. Log in to the CKafka Console.
2. In the instance list, click Configure Alarm in the "Operation" column to enter the alarm configuration page. You must configure an alarm for an instance to prevent exceptions caused by traffic surges or exceeded specification threshold.
   
3. In the instance list, click the ID of the desired instance/topic to enter the instance details page.
4. At the top of the instance details page, click the Monitoring of This Instance tab to view monitoring data.

CKafka Alarm Policy

You can create an alarm to promptly remind yourself to take corresponding measures when the status of CKafka changes. The created alarm can determine whether an alarm notification should be sent based on the comparison between the monitored metric and the given threshold in the selected time period.
You can take appropriate precautionary or remedial measures in a timely manner when the alarm is triggered. Therefore, properly created alarms can help you improve the robustness and reliability of your applications. For more information on alarms, please see Creating Alarms in Cloud Monitor.
