问题
As per the documentation of docker. We can get CPU usage of docker container with docker stats command. The column CPU % will give the percentage of the host’s CPU the container is using.
Let say I limit the container to use 50% of hosts single CPU. I can specify 50% single CPU core limit by --cpus=0.5 option as per https://docs.docker.com/config/containers/resource_constraints/
How can we get the CPU% usage of container out of allowed CPU core by any docker command? E.g. Out of 50% Single CPU core, 99% is used.
Is there any way to get it with cadvisor or prometheus?
