Measure Disk performance

[skip]

Hello all

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 wouldnt be doable in my situation because the OS doesnt
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 dont see counters for logical disk. Should i manually create these
monitors?

I would use logical. Physical is going to grab a gang of mount points. We
use logical for our clustered exchange.

You may have to create these, but I believe they should be enabled by
default via the W2KX manaement pack. Change your scope in the authoring
pane for rules for windows server blah blah blah then look for logical and
you should find several collection rules for logical disk.
