Nice plugin with a few flaws.
I made the modifications suggested by other comments here and a few other small changes. I named the "new" plugin check_snmp_ibm_imm-ng, which can also be found here on
Thank you ulric!
CPU temp critical reading in MIB is 0. Added this check to avoid false critical on CPU temp.

if test "$tempCritical" -gt 0 -a "$tempTemp" -ge "$tempCritical";
We got a new IBM x3550 M4 Server, and this server has a temperature sensor named “Mezz Card Temp” that always give 0 as the temperature. This sensors looks like it is for an optional Mezzanine card that is not installed in this server. To avoid this server to always report warning on temparature, I had to modify the script to report OK on sensors that have a Fatal temparature level of 0. My modified temparature check looks like this:
if test "$tempFatal" -eq "0"; then
elif test "$tempTemp" -ge "$tempCritical"; then
elif test "$tempTemp" -ge "$tempNoncritical"; then
Excellent plugin!
I was wondering about the return value for non-critical errors. (critical/red)
But it wasn't a problem to change this value to "1" (warning/yellow). This makes more sense to me.

Thanks for the excellent plugin that saved me quite some work, I've tested it on our Nagios deployment to monitor our lab equipment composed of 3250,3650 and 3850 it works like a charm!

This plugin works well for x3620 M3 servers.

As with many plugins, the assumption is that Nagios runs on Linux. When running this plugin on Solaris, the instances of "grep -F" need to be changed to use /usr/xpg4/bin/grep, instead of the default grep in /usr/bin.
Owner's reply

Thanks for the comment. Posix requires grep -F. I suppose Solaris has an fgrep which does the same thing but that is not in Posix so it is (in theory) less portable. I guess Solaris users will just have to suffer until Oracle fix it. :)

works on x3250 M3 for me - could only test "health" with putting out an HDD.

temperatures etc are alle shown correctly

thank you very much
