Why in the config are you using 
1.3.6.1.4.1.476.1.42.3.4.1.2.3.1.3
and when using snmpget using
1.3.6.1.4.1.476.1.42.3.4.1.2.3.1.3.1
?
Wouldn't it make more sense to use the full OID that you know returns the
correct value?>

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

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_]

'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.
