POD's CPU utilization in percentage

Hi All,

Right now I have one panel which is displaying POD’s cpu utilization in core.
For that I am using below query.

sum by (pod)(rate(container_cpu_usage_seconds_total{namespace=“”,pod=~“”,container=~“.+”,image!=“”} [1m]))

But, now I need to represent it in percentage usage (group by pod).
Is there any inbuilt metrics for this?
How can this be achieved ?

Any help will be appreciated.
