'prometheus query is showing almost twice value for CPU usage of pod as compared to kubectl top command
Prometheus query that I am running :
sum(rate(container_cpu_usage_seconds_total{container_name!="POD",pod!=""}[5m])) by (pod)
this gets me around 450m.
And kubectl top for that particular pod is 225m.
Am I missing something?
Prometheus query is always showing 2x usage.

Can you check trying as mentioned in https://stackoverflow.com/a/40391872/2310790 ? sum (rate (container_cpu_usage_seconds_total{image!=""}[1m])) by (pod_name)
The kubectl top command returns current CPU and memory usage for a cluster's pods or nodes, or for a particular pod or node if specified. And you had mentioned 5m rate. So i am suspicious if the rates impact your comparison.
