The oc get pods command with the --output yaml option can be used to determine the memory and CPU requests and limits for the pod.

oc get pod/foo-9mzm2 --output yaml

Something like this should be returned.

• requests = the amount of memory / CPU that is reserved or allocated for the container. If a container exceeds its memory limit, the container will should be terminated.
• limit = the maximum amount of memory / CPU the container can request. If a container exceeds its memory request, its pod should be evicted if the node the pod is running on runs out of memory.

spec:
  containers:
    resources:
      limits:
        cpu: 500m
        memory: 512Mi
      requests:
        cpu: 10m
        memory: 256Mi

The oc exec command can be used to get the real time memory usage in bytes of the pod.

oc exec foo-9mzm2 -- cat /sys/fs/cgroup/memory/memory.usage_in_bytes

Something like this should be returned. In this example, the pod is currently using 568414208 bytes of memory (568 MB).

568414208

And here is how you can return the CPU statistics.

~]$ oc exec foo-9mzm2 -- cat /sys/fs/cgroup/cpu/cpuacct.stat
user 289
system 58

And here is how you could divide the bytes by 1024 to get the value in KB.

~]$ bytes=$(oc exec foo-9mzm2 -- cat /sys/fs/cgroup/memory/memory.usage_in_bytes); echo $(($bytes / 1024))
83180

Or in MB.

~]$ bytes=$(oc exec foo-9mzm2 -- cat /sys/fs/cgroup/memory/memory.usage_in_bytes); echo $(($bytes / 1024 / 1024 ))
