Unable to monitor NFS persistent volume storage using Prometheus

Solution Verified - Updated -

Issue

  • kubelet_volume_stats_available_bytes should return metrics for persistent volumes available in the cluster.
  • When I run this query in the OpenShift provided prometheus stack, it does not return any records for NFS volumes.

Environment

  • Red Hat OpenShift Container Platform
    • 3.x
    • 4.0-4.1
