Can somebody clarify me regarding oc adm top command in openshift. As per redhat (https://access.redhat.com/solutions/3654511) top command will show resources available. But in my cluster it is not the case.
#oc adm top nodes
node2 3166m 6% 102920Mi 82% here it is showing memory is 82% used. But when I log in to server I see different values.
#free
total used free shared buff/cache available
Mem: 131857820 52185484 2347628 42496 77324708 78817524usage is around 52% .
Am I reading this wrong way?
Kubectl top nodes as like as oc adm top nodes rely on information from cgroups.
Free , top and other native linux tools rely on information from procps
