Support more metrics in NodeGetVolumeStats and add ControllerGetVolumeStats

Open wnxn opened this issue 6 years ago • 0 comments

  • NodeGetVolumeStats is useful for volume observability. But it is only able to report the inode and capacity metrics. Can we support more metrics, such as iops and throughout, in our CSI spec?

  • In our storage system, we can get some volume metrics from storage system API. Shall we add ControllerGetVolumeStats? In this way, CO could get unmounted volume stats.
