CloudMonitor:Why is the CPU utilization displayed as 0% in the Cloud Monitor console?

This topic describes why the CPU utilization is displayed as 0% in the Cloud Monitor console.

This issue is caused by low CPU utilization. The CPU utilization is around 0.5%, as shown in the following figure.

An Elastic Compute Service (ECS) instance reports the CPU utilization to Cloud Monitor once a minute. Cloud Monitor displays the average CPU utilization in the last five minutes in the console. If the average CPU utilization in the last five minutes is less than 0.5%, Cloud Monitor displays the CPU utilization as 0%.
