4.4. Verifying that the Tuned profiles are applied

Procedure

1. Check which Tuned pods are running on each node:

   $ oc get pods -n openshift-cluster-node-tuning-operator -o wide

   Example output

2. Extract the profile applied from each pod and match them against the previous list:

   $ for p in `oc get pods -n openshift-cluster-node-tuning-operator -l openshift-app=tuned -o=jsonpath='{range .items[*]}{.metadata.name} {end}'`; do printf "\n*** $p ***\n" ; oc logs pod/$p -n openshift-cluster-node-tuning-operator | grep applied; done

   Example output
