When I look at DFM 3.8 (in areas like Storage System -- Network Throughput) where the counter is listed as mb_per_sec or kb_per_sec, is that measurement megabytes/kilobytes or megabits/kilobits per second?
Also when I compare throughput between DFM and sysstat the numbers seem quite different--what am I missing?
Here I have about 70kB/s in sysstat and 150 mb_per_sec (load_total_mbps) or 150,000 (nas_throughput) kb_per_sec in DFM (NAS is the only thing on the filer so they are roughly the same once scaled).

Those timelines are identical. This is not a one time discrepancy--I see it always on multiple clusters. We used network port statistics as a tie breaker and decided that Operations Manager is incorrect. The sysstat and network port statistics lined up nicely.
I was hoping someone else would chime in on their experience, but perhaps I will have to open a case with NetApp to get to the bottom of it.
