[mrtg] Possible Bug / Incorrect Config mrtg 2.15.0

[Matthew Petach]

In digging through the MRTG.pm library, it seems the matching of
the options is not case insensitive in 2.10.15; the matching of "Options"
is lc'd, and the actual target name is lc'd, but $3, the string of actual
options, is left intact when compared to the list of known options,
which are in lower case.  If you change Bits to bits, MRTG should
start multiplying by 8 again.

Peeps,

We have an interesting issue with this config. The oid is an octet count 
for an ATM PVC connection and when queried directly via an snmpget every 
5 minutes produces a value 8 times what mrtg retrieves.

As you can see we have added an * 8 currently to make mrtg report correctly.

Can anyone see any reason why this doesnt work.

It has changed since we upgraded from rrdtool 1.0.48 and mrtg 2.13.2 to
rrdtool
1.2.0 and mrtg 2.15.0. The previous version of rrdtool and mrtg counted this
interface as 8 times what the current version is with no changed to the
config,
except adding the rrdtool config to the top
