[mrtg] Help reading the OIDs for a Emerson/Libert unit

[Mills, Charles]

Ok....I use Fernando's oid string for temp and humidity and it works.

 

I guess I learned something today, now to poke around a bit more and figure out what exactly it was that I learned.

I monitor two Lieberts for temperature and humidity. Same OIDs, it seems. This is what my target line looks like.

 

Target[l1-temp-hum]:.1.3.6.1.4.1.476.1.42.3.4.1.2.3.1.3.1&.1.3.6.1.4.1.476.1.42.3.4.2.2.3.1.3.1:snmpstr at ipaddress

Hi all ... I'm kind of at my wit's end with this problem and not sure what I'm doing wrong in the MRTG side of things.  I don't do a lot of "custom" cfg files relying mainly on the cfgmaker.

 

I have a Liebert 22 Ton CRAC unit in my data center and I'd like to use it as a temp sensor for that part of the computer room.  I believe I have the correct OID but MRTG doesn't seem to evaluate/expand it right or I have something else wrong in the config file:

 

Running the MRTG program yields:

 

env LANG=C /usr/local/mrtg-2/bin/mrtg /etc/mrtg/Liebert-AC-4-temp.cfg

2008-04-08 10:31:28: ERROR: Target[liebert-ac-4][_IN_] '.1.3.6.1.4.1.476.1.42.3.4.1.2.3.1.3. $target->[0]{$mode} ' evaluated to 'Ç*19773129' instead of a number

2008-04-08 10:31:28: ERROR: Target[liebert-ac-4][_OUT_] '.1.3.6.1.4.1.476.1.42.3.4.1.2.3.1.3. $target->[0]{$mode} ' evaluated to 'Ç*38089656' instead of a number

 

./snmpget.pl -c 'RO-snmp-string' <ip of liebert webcard> .1.3.6.1.4.1.476.1.42.3.4.1.2.3.1.3.1

 

Returns:

 

 

.1.3.6.1.4.1.476.1.42.3.4.1.2.3.1.3.1 = INTEGER: 73

 

 

Persuing the docs didn't yield too much that would point me in the right direction...if anyone has ever tackled something like this I'd appreciate the help.

 

Chuck
