Merged disk checks

[Gerald]

I have to agree with the disadvantages. We worked around it by going to
check_snmp and just hitting the disk partitions over snmp. This allowed us
to only have to install snmp on the servers (some already had it) and we
can monitor more than the plugins have come up with.

I don't mean to offend anyone by this, but snmp has also undergone much
more scrutiny for security issues than any of the client side
netsaint/nagios plugins have.

Setup a read only user. Season with tcpwrappers to taste and all of the
thresholds can be set from the netsaint config. I haven't done it yet, but
I intend to do the mrtg/apan integration into netsaint and I believe the
check_snmp_disk that I've setup will graph more information.

I posted to the list a while back about how I setup the check disk if you
want to search for it.

Good Luck,

Gerald
