Monitoring, dashboards and metrics for Local PV HostPath storage engine

[tmvfb]

openebs/monitoring repository currently supports dashboards and alerts only for Mayastor, LocalPV LVM, LocalPV ZFS OpenEBS storage engines (see README).

Are there plans to make metrics available for Local PV HostPath engine as well? It would be great to be able to use at least the kubelet metrics (e. g. kubelet_volume_stats_used_bytes) which currently seem to be broken and show the same (aggregate?) values for all the PVs.

Using this as a temporary solution, allows to monitor how much space is occupied by which PV. For some reason it doesn't seem to be accurate for some of the PVs.

kubelet_volume_stats_used_bytes fetches metrics for the underlying file-system. Local PV Hostpath volumes share the same underlying file-system. So, those metrics will be aggregate for all the PVs on that fs.
This is a known limitation.
