This is the output of my kubectl describe node <node-name> -o yaml command:

  (Total limits may be over 100 percent, i.e., overcommitted.)
  Resource                   Requests    Limits
  --------                   --------    ------
  cpu                        374m (4%)   3151m (39%)
  memory                     493Mi (1%)  1939Mi (7%)
  ephemeral-storage          0 (0%)      0 (0%)
  attachable-volumes-gce-pd  0           0

Τhe requests are calculated based on the corresponding pod field? (resources.requests) Or is the node able to report the actual resource usage?

If the above is not the actual usage, is there a way to get the corresponding actual metrics?

(I mean via kubectl and not using something like prometheus and node-exporter)
