OK, I won't claim to be an expert on MRTG or Perl by any stretch of the
imagination, but I was wondering... Since you can do math on items
you're processing, is it possible to run an Absolute Value function on
the OID you're plulling. Set Maxbytes for 14 or something (to make sure
you catch overages) and the in the legends you simply say -12V.
