Description Tomas Smetana 2020-12-16 13:19:41 UTC 
There is a new metric in kubernetes 1.20: pv_collector_total_pv_count added via https://github.com/kubernetes/kubernetes/pull/95719. The plugin_name and volume_mode should be collected via telemetry in order to provide overview of the cluster storage usage.
