tencent cloud

Overview

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.

CKafka allows you to monitor the resources created under your account, including instances, topics, and consumer groups, so that you can keep track of the status of your resources in real time. You can configure alarm rules for monitoring metrics. When a monitoring metric reaches the set alarm threshold, Cloud Monitor will notify you of exceptions in time via email, SMS, phone call, etc.

Directions

Configuring alarm policy

The created alarm can determine whether an alarm notification should be sent based on the comparison between the monitoring 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 because the status of CKafka changes. Properly creating alarm policies can help improve the robustness and reliability of your applications.

Note：

Be sure to configure alarms for your instance to prevent exceptions caused by traffic spikes or specification limits.

1. Log in to the CKafka console.
2. In the instance list, click Configure Alarm Policy in the Operation column to enter the alarm configuration page.
3. On the alarm configuration page, select a policy type and instance, and set the alarm rule and notification template.
   • Policy Type: Select CKafka.
   • Alarm Object: Select the CKafka resource for which to configure the alarm policy.
   • Trigger Condition: You can select Select template or Configure manually. The latter is selected by default. For more information on manual configuration, see the description below. For more information on how to create a template, see Creating trigger condition template.

     Note：

     • Metric: For example, if you select 1 minute as the statistical period for the "Disk Utilization" metric, then if the disk utilization exceeds the threshold for N consecutive data points, an alarm will be triggered.
     • Alarm Frequency: For example, "Alarm once every 30 minutes" means that there will be only one alarm triggered every 30 minutes if a metric exceeds the threshold in several consecutive statistical periods. Another alarm will be triggered only if the metric exceeds the threshold again in the next 30 minutes. For the metrics for which we recommend you configure an alarm policy, see Monitoring Alarm Policies Recommended for CKafka.

   • Notification Template: You can select an existing notification template or create one to set the alarm recipient objects and receiving channels.
4. Click Complete.
