[mrtg] Issue with MRTG and explicit OIDs

[Peter Dolkens]

Hi all,

  I'm trying to set up some disk monitoring on my Synology NAS, using MRTG
(windows).

  The Target I'm using is:
Target[piper.ddrit.com_DISK]:
1.3.6.1.2.1.25.2.3.1.6.33&1.3.6.1.2.1.25.2.3.1.5.33:public at piper.ddrit.com

  If I query either of these values via the command line, I get a correct
result.
  If I query either of these values individually in MRTG, I get a correct
result.
  If I use the line above, then the 2nd value has 2147483648 subtracted
from the collected values.

  Does anyone know why it's doing this, or how to fix it?

  It's annoying because I'm intending to expand my NAS, and using this
counter, I could theoretically display relative capacity usage
(displayrelpercent) but right now MRTG can't seem to collect the 2nd
counter properly, which is putting a damper on things.

  Thanks,
Pete
