Plugin for monitoring Cisco UCS through SNMPv2 and SNMPv3.

You don't need install any MIB for this plugin.
It's using Net::SNMP PERL module.

When you send SNMP request to virtual IP of UCS Manager you'll get reply from IP active Fabric Interconnect! Many SNMP implementation don't accept this behavior by default!!!

If you get a no OID found this occurs if you have no alerts/warnings or information at all to report, the error kind of threw me for a loop to. I just commented that No OID found as long as I verified I was connecting correctly already.

I also made a modification to the faults check to report warnings correctly to Nagios. Here is the modified section I did.

if($type eq "fs") {
if($results[$i] > 4) {
$exit_state = NAGIOS_CRITICAL;
$output .= " " . $descriptions[$i] . "
";
}
if($results[$i] == 4) {
if ($exit_state ne NAGIOS_CRITICAL) {
$exit_state = NAGIOS_WARNING;
}
$output .= " " . $descriptions[$i] . "
";
}
next;
}
[nagios@nagios libexec]$ ./check_ucs.bin -H 10.10.10.1 -C public -T ci -N chassis-2
No OID match! Check your -H and -N or -T

We have six chassis, only fail in 2 and 5,6. The state of all chassis is ok and we haven't any alarm.

./check_ucs -H 10.1.5.1 -C public -T ct -N chassis-1
No OID match! Check your -H and -N or -T
Owner's reply

It's look interesting. Are you sure that IP and comunity are right?
Have you enable SNMP in Fabric Interconnect managment?

The plugin is excellent, but i have detected a bug. When I check a different IP of the UCS, I must receive an error but I receive "0 objects OK".
