How To Get Pod Cpu And Memory Usage From Metrics-server?

I currently have metric server installed and running in my K8s cluster. Utilizing the the kubernetes python lib, I am able to make this request to get pod metrics: from kubernetes

Solution 1:

Based on the official repository you can query kubelet stats endpoint:

$ curl --insecure https://<node url>:10250/stats/summary

which will return stats of full pods. If you want to see metrics for pod/container itself, type:

$ curl --insecure https://<node url>:10250/{namespace}/{podName}/{uid}/{containerName}

Let's take a look for example:

{ "podRef": 
    { "name": "py588590", 
      "namespace": "myapp", 
      "uid": "e0056f1a" 
    }, 
  "startTime": "2019-10-16T03:57:47Z", 
  "containers": 
    [ 
      { "name": "py588590", 
        "startTime": "2019-10-16T03:57:50Z"
      }
    ]
}

These requests will works:

http://localhost:10255/stats/myapp/py588590/e0056f1a/py588590
