• Visualize Nodes metrics
  
  
  
  
• Visualize Pods metrics
  
  
  
  

• Check Metrics API version:
  

  $ kubectl get --raw /apis/metrics.k8s.io/

  {
    "kind": "APIGroup",
    "apiVersion": "v1",
    "name": "metrics.k8s.io",

    "preferredVersion": {
      "groupVersion": "metrics.k8s.io/v1beta1",
      "version": "v1beta1"
    }
  }

• Check available resources of the Metrics API:
  

  $ kubectl get --raw /apis/metrics.k8s.io/v1beta1

  {

          "get",
          "list"
        ]
      }
    ]
  }

• Node metrics:
  
  To print node metrics, use the following command:
  kubectl get --raw /apis/metrics.k8s.io/v1beta1/nodes/<NODE_NAME>
  
  List existing nodes:
  

  $ kubectl get nodes

  NAME       STATUS   ROLES    AGE   VERSION
  minikube   Ready    master   17h   v1.18.3

  Print Node metrics:
  

  $ kubectl get --raw /apis/metrics.k8s.io/v1beta1/nodes/minikube

  {
    "kind": "NodeMetrics",
    "apiVersion": "metrics.k8s.io/v1beta1",
    "metadata": {
      "name": "minikube",
      "selfLink": "/apis/metrics.k8s.io/v1beta1/nodes/minikube",

    "usage": {
      "cpu": "239m",
      "memory": "1209836Ki"
    }
  }

• Pod metrics:
  
  To print pod metrics, use the following command:
  kubectl get --raw /apis/metrics.k8s.io/v1beta1/namespaces/<NAMESPACE>/pods/<Pod_NAME>
  
  List existing Pods:
  

  $ kubectl get pods --namespace kube-system | grep metrics-server

  NAME                               READY   STATUS    RESTARTS   AGE
  metrics-server-7bc6d75975-qwgxt    1/1     Running   0          3h29m

  Print Pod metrics:
  

  $ kubectl get --raw /apis/metrics.k8s.io/v1beta1/namespaces/kube-system/pods/metrics-server-7bc6d75975-qwgxt

  {
    "kind": "PodMetrics",

        }
      }
    ]
  }

• Print 'kubectl top' command help:
  

  $ kubectl top --help

  Display Resource (CPU/Memory/Storage) usage.
  
   The top command allows you to see the resource consumption for nodes or pods.
  
   This command requires Metrics Server to be correctly configured and working on the server.
  
  Available Commands:
    node        Display Resource (CPU/Memory/Storage) usage of nodes
    pod         Display Resource (CPU/Memory/Storage) usage of pods
  
  Usage:
    kubectl top [flags] [options]

• Print Node resources usage:
  

  $ kubectl top node minikube

  NAME       CPU(cores)   CPU%   MEMORY(bytes)   MEMORY%
  minikube   256m         6%     1156Mi          14%

  You can use the following command to display resources of all nodes:
  kubectl top node
  
  
• Print Pod resources usage:
  

  $ kubectl top kube-system pod metrics-server-7bc6d75975-qwgxt --namespace

  NAME                              CPU(cores)   MEMORY(bytes)
  metrics-server-7bc6d75975-qwgxt   1m           11Mi

  You can use the following command to display resources of all pods:
  kubectl top --namespace kube-system
  
  You can use the option --containers to display resources of all containers of a pod:
  kubectl top pod metrics-server-7bc6d75975-qwgxt --containers --namespace kube-system
  

• Print Node information:
  

  $ kubectl describe node minikube
