Description:

The PersistentVolumes provisioned by kubevirt CSI driver doesn't generate associated metrics, mainly the PVC utilization metrics.

This feature request is to enable such metrics so that users can view the utilization from RHOCP console and setup alerts as per their requirements without letting the associate pods to crash.

Below metrics doesn't yield any results when kubevirt CSI driver is used. 

kubelet_volume_stats_used_bytes

 The kubelet will start extracting the information from the kubevirt CSI driver and will expose it accordingly.

Additional Info:

The associated code is available here and states that is unimplemented:
