Re: How best to determine volume usage



The volume usage information about PVCs should be available as metrics from kubelet (or openshift-node process) in prometheus format.

When using dynamic volumes from cloud providers (e.g. cinder with
OpenStack) or GlusterFS volumes for creating PVCs these volumes do not
get displayed when using the 'df' command on the the node so it not
straight forward to determine how full the volume is.

Similarly 'oc describe pv/pv-name' lists the capacity of the volume, but
how much of that capacity has been used.

What is the best way to achieve this?
