Hi All, When I tried as mentioned in documentation [1] to access cluster metrics (resource usage) through the REST endpoints it gives null values. But the data is passed to the storage backend, "InfluxDB" when I checked the data tables in the database.
AFAIU there are missed configurations in the "Heapster" that I currently use, which comes in default in Kubernetes. As suggested by Manjula, the current approach is to delete the "Heapster" pod and re- create the pod with correct configurations. I would highly appreciate your suggestions on this approach.
