Tencent Cloud TCHouse-P provides a Performance Monitoring Dashboard, allowing users to observe the historical and current status of the performance metrics of each node in the cluster. Tencent Cloud TCHouse-P offers an alarm notification feature to inform users of sensitive metrics exceeding thresholds, such as the disk usage of each node.
Performance Monitoring
Enter Tencent Cloud TCHouse-P, click on Cluster Name in the cluster list to go to the cluster details page. In Performance Monitoring, you can view various metrics of the cluster. When there are multiple nodes, you can select the cluster node you want to view in Node Dimension.

When creating an alarm policy, Policy Type can be selected as cdwpg data warehouse - cluster monitoring, cdwpg data warehouse - primary node monitoring, and cdwpg data warehouse - compute node monitoring. This section takes compute node monitoring as an example.
1. Select Policy Type as cdwpg data warehouse - compute node monitoring.
2. Set the Alarm Target, you can choose different compute nodes groups through the dropdown menu.
3. Configure the Trigger Condition, through selecting a template or manual configuration.
If selecting trigger condition: Select Template, you can click on Add Configuration Trigger Condition to configure the threshold for triggering an alarm for each metric. Once the metric reaches the threshold condition, the system will send you an alarm message. You can also click on Modify Template to modify an existing template.
