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.

=20

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:

=20

Running the MRTG program yields:

env LANG=3DC /usr/local/mrtg-2/bin/mrtg /etc/mrtg/Liebert-AC-4-temp.cfg

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.
