Reading the values seem to work in MRTG.  You try to graph them and
nothing shows up.

Using gauge, nothing shows up.  Probably due to a MaxBytes setting
lower than 9750

Using plain counter (no option) nothing shows up.  Probably due to 
a increase lower than 26 per 5 minutes.

Check your log files.  The first line should show the raw values as
seen by MRTG and should be roughly the same as the values fetched using
snmpget.  I think this will be okay.

You could try to multiply the target by 100000 and see what this
does.  Be sure to also modify the MaxBytes (and/or AbsMax) setting.

cheers
