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.

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:

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.
