Yes, but I don't believe it provides me with anything I don't already have.

I believe that the SNMP DiskIO MIB polls the information from iostat,
and hence, would be nothing more than a middle-man for information I
already have direct access to.
In addition, to use SNMP, I'd have to install apache, the mibs, the
snmp tools, gnuplot, and who knows what else. Unfortunately, with
all this crap, I begin to affect the very performance I'm trying to
measure :(
Of course, I'd love to be proven wrong and told that SNMP has some
magical powers or otherwise 'all-access pass' into Disk IO
metrics that iostat is incapable of providing, and therefore, it's
worth going around and installing all this stuff on the 64+ nodes to
get this information :)

It may look like I'm just sitting here doing nothing,
but I'm really actively waiting for all my problems to go away.
If you're not having fun, you're not doing it right!
