Node summary

Kubernetes manages the workloads by embedding containers into Pods, which then operate on nodes. Monitoring the health of a Kubernetes cluster node can help you understand the components that impact the health of the nodes in your cluster.

The Node summary dashboard displays the details of the node and the resources that are used by the node based on the metrics that are collected and displayed.
