For Boundary Clock, the GM clock class is read via the PMC command every few seconds and logged only when there is a change in CLOCK CLASS. This causes the sidecar to miss updates on the clock class value if it restarts or fails to read the first event. Increasing the frequency ensures that the latest clock class is always updated.

    1.Run ptp and verify clock class with event enabled 
    2.verify localhost9091:metrics  for clock class , should be 6 
    3.kill side car (daemon shoul dbe still running ) 

    oc exec ds/linuxptp-daemon -c cloud-event-proxy -n openshift-ptp -- sh -c "kill -9 \$(ps aux | grep cloud-event-proxy | grep -v grep | awk '{print \$2}')"
    4. wait for the side car to recover 
    5. verify the clock class metrics 

    

    should show 6 

  doesn't have clock class  metrics
