Kubernetes heapster - Grafana doesn't display influxdb data


I deployed heapster with influxdb and grafana by following heapster-influxDB guide. When accessing the grafana instance I couldn't see any data in graphs(grafana service exposed to outside from NodePort). There are no errors in heapster and influxdb logs as attached below.

What could be the issue here? Really appreciate a positive feedback.

$ kubectl version
Server Version: version.Info{Major:"1", Minor:"1", GitVersion:"v1.1.3", GitCommit:"6a81b50c7e97bbe0ade075de55ab4fa34f049dc2", GitTreeState:"clean"}

Solution

  • It happens to be the Heapster master branch version is not compatible with some Kubernetes clusters. I tried following latest beta version and it works.
