Subject: [msmom] Measure Disk performance Exchange

If I want to measure and track the disk activity on my exchange 2003 server,
should I target the logical disk or the physical disk. The exchange database
and log files are on a netapp SAN, so I would think trying to target at the
physical disk level wouldn’t be doable in my situation because the OS doesn’t
really have information on the physical disk's that are on the SAN, it only
see's the volume.

the counters I am interested in tracking are average disk reads, writes and
queue length. I see "Physical Disk" performance counters under the exchange
MP, but I don’t see counters for logical disk. Should I manually create these
monitors?
