k8s master checks for kubelet status at frequent intervals. Maybe we can change that time and that makes the node not-ready. But that doesn't always mean that the node got rebooted.

  1. How to change kubelet status check frequency?
  2. If I don't want to change the kubelet status check frequency, then how could I get to know whether a node got rebooted?

As per the official Kubernetes documentation the frequency can be changed using the --node-status-update-frequency duration flag, but please see the limitations. To check node condition you can reference to here, if you want to check strictly node uptime you please see this.
