DFM performance data missing

A bunch of counters within the DFM performance reporting show 0.0 for their value.  Other counters show actual data.  Has anyone seen this before?   DFM 3.7.1

An example is below, i see this for most of the performance data

Re: DFM performance data missing

Are there luns in those volumes? Because it's the SAN report, maybe it only report latencies when luns are in that volume. I still running 3.6 and I don't know this report. But when I saw your volume names, those could indicate that those volumes don't have luns.

Just a small suggestion.

Re: DFM performance data missing

All but 2 or 3 have LUNs in them.

I chose that report as an example, but any report shows similar results....

Re: DFM performance data missing

san_ops for volumes is defined as the sum of san_read_ops, san_write_ops and san_other_ops. Can you verify if there are operations being performaned on your LUNs (using the stat CLI on the filer or using NMC) ?
