 |Shows the number of successful SSH authentications into the node.
 |The non-zero value shows that someone might have made manual changes to the node. Such changes might cause irreconcilable errors due to the differences between the state on the disk and the state defined in the machine configuration.

 |Logs errors received during failed drain. *
 |While drains might need multiple tries to succeed, terminal failed drains prevent updates from proceeding. The `drain_time` metric, which shows how much time the drain took, might help with troubleshooting.
 
 For further investigation, see the logs by running:
 
 `$ oc logs -f -n openshift-machine-config-operator machine-config-daemon-<hash> -c machine-config-daemon`
