When the vSphere CSI driver is installed, we do not collect metrics of its CSI drivers.

Comment 4 Jan Safranek 2021-04-23 10:12:08 UTC

`unknown-driver` is OK. It comes from the sidecars when it calls GetPluginInfo to get the driver name. The sidecar does not know name of the driver yet at that point. Therefore it's accounted as 'unknown-driver'. You could see also other calls with `unknown-driver`, such as Probe().

Thanks, change the status to Verified.
