It was planned at some point, but we do not have enough devs and time to work on such integrations right now. It will be added at some point for sure. I'd love to only use kubernetes metrics API and get rid of heapster/prometheus hard dependencies. I'll have to investigate if this is possible.

kubernetes may not have the metrics API. maybe it need a long time

floreks commented 6 years ago

It does: https://kubernetes.io/docs/tasks/debug-application-cluster/core-metrics-pipeline/

I deploy heapster and metric-server. i test the metric-server api. it works well. from the api , we can get one metric of the pod or one metric of all pods. but metric server does't store history metrics http://10.110.17.88:8080/apis/metrics.k8s.io/v1beta1/nodes/node2 response is { "kind": "NodeMetrics", "apiVersion": "metrics.k8s.io/v1beta1", "metadata": { "name": "node2", "selfLink": "/apis/metrics.k8s.io/v1beta1/nodes/node2", "creationTimestamp": "2017-11-10T09:57:48Z" }, "timestamp": "2017-11-10T09:57:00Z", "window": "1m0s", "usage": { "cpu": "185m", "memory": "2471876Ki" } }

i think metric-server can not be integrated with dashboard at present

It is still being actively developed. Even though currently it returns only current metric, it might change in the future.
