I added option for port. Added output to the first line if there is a critical or warning and a counter for number of checks OK.
You can enter multiple oid's, but the format MUST be ( label:oid:warn:crit:g:n,label:oid:warn:crit:l:a,... ),comma seperated.
Example (IBM Blade Chassis Voltages):
check_snmp.pl -H testbc -C public -p 161 -V 1 -t TESTBC_volt -O plus5:.1.3.6.1.4.1.2.3.51.2.2.2.1.1.0:4:3:l:n,plus3.3:.1.3.6.1.4.1.2.3.51.2.2.2.1.2.0:3:2.6:l:n,plus12:.1.3.6.1.4.1.2.3.51.2.2.2.1.3.0:11:10.5:l:n,minus5:.1.3.6.1.4.1.2.3.51.2.2.2.1.5.0:-4:-3.7:g:n,plus2.5:.1.3.6.1.4.1.2.3.51.2.2.2.1.6.0:2.2:2:l:n,plus1.8:.1.3.6.1.4.1.2.3.51.2.2.2.1.8.0:1.5:1.2:l:n

And if you want temperature I recommend you just download check_snmp_temperature.pl. Take a look at how its code too to learn how to write nagios plugins in Perl that retrieve data by SNMP. Then consider what is needed for your setup and write a new perl plugin (if it does not already exist) that you'd be proud of.
Yeah, I've been writing plugins for nagios/netsaint for over a decade now.
There are lots of plugin scripts out there that are wrappers. And most scripts that utilize protocols, need to wrap themselves around libraries.
The check_snmp plugin does not take into consideration the output a device will generate. It is not that good, but a good start for most people.
I have seen lots of scripts which give you this output, or that output, but never one I can ask for whatever output I am looking for. So I wrote script that is easy enough to do just that. I can use this script to check every OID on any any device, and out put the data so it is useful for performance data or not.
Yes, I am proud of all of my code. Because I wrote it, and it works, and it is simple to understand and expand upon.
