How is ECSServiceAverageCPUUtilization metric caluclated?

How Is ECSServiceAverageCPUUtilization actually calculated? It is obvious that it gets the average, but what is the actual time duration? Average of last 15 minutes? Less?

The "Average" in ECSServiceAverageCPUUtilization does not mean a "time duration". The "Average" in this metric refers to an average of CPUUtilization overall all tasks in the service.

The details how this is calculated are here:

Service utilization is measured as the percentage of CPU and memory that is used by the Amazon ECS tasks that belong to a service on a cluster when compared to the CPU and memory that is specified in the service's task definition.

The metrics are collected in 1 minute intervals.

The "time duration" has meaning when you define a Target Tracking scaling policy to auto-scale your service.
