Viewing Monitoring Information of a Cluster

Scenario

CES monitors the running status of ClickHouse clusters. You can view the monitoring metrics of ClickHouse on the management console. According to the monitoring information, you can quickly learn about cluster health status and key system information.

Monitoring Function

The cluster monitoring function consists of compute node and ZooKeeper metric monitoring. You can adjust the time range of monitoring data in each module to view historical data at different time. You can also adjust the time granularity of monitoring data to view data in different dimensions. If you want to view monitoring data in real time, enable automatic refresh. The platform can automatically refresh monitoring graphs at intervals of 1 hour, 3 hours, 12 hours, 24 hours, and 7 days.

If you are interested in a metric graph, you can click the zoom-in button to view the graph or export the graph.
