The Cluster Agent runs within your Kubernetes cluster. Metrics reported for containers are taken from the Kubernetes Metrics Server. Users need to install the metrics-server on their cluster to see container metrics. Once deployed, it discovers nodes in your cluster and starts collecting metrics from the Kubelet API. The Containers Dashboard shows the resource utilization metrics of your containerized applications.
The Containers page lists all containers to be monitored that are used by an application that is registered to the Controller.

Memory Usage: Hardware Resources|Memory|Used %
CPU
