I am looking for a way in Kubectl that shows the history of a node ready/notready status and the timestamp for the transition time.
History of node status (ready or not) and last transition time can be seen in the output of kubectl describe nodes under the Conditions: section:
Name: master-node-cf430c398
...
Conditions:
...
