K8S Node dashboard

As an administrator, use the K8S Node dashboard to understand the following information:

  • The CPU, memory, storage, and volume profiles on a Kubernetes node
  • Details of the events that are related to a Kubernetes node
  • The current status of a pod.

The following image shows the K8S Node dashboard:
