CPU utilization

In AWS, CPU utilization is measured as a percentage, with values ranging from 0% to 100% for a single CPU core. The image appears to show a CPU utilization value, but without being able to see the image clearly, I can provide general information about how CPU utilization is represented in AWS.

For a single CPU core, 81.8% would represent high utilization, while 0.818% would represent very low utilization. The correct interpretation depends on the context and how the metric is being reported.

In CloudWatch metrics for EC2 instances, CPU utilization is reported as a percentage between 0% and 100% for a single core. However, if an instance has multiple CPU cores, the total CPU utilization can exceed 100%. For example, a 4-core instance can have a CPU utilization range of 0% to 400%.

When viewing CloudWatch metrics for CPU utilization, the value is typically displayed as a percentage without decimal points for high values (like 81.8%) or with decimal points for low values (like 0.041%).

The CPU utilization metric in the image is 0.818%.
If it were 81.8%, it would be displayed as 81.8%.
