MRTG logfiles are already calculated values so you need to insert them
in an RRD file using GAUGE. Afterwards, you can change the datasource
type into COUNTER.

I'm not sure but I think it was you that explaind this to me some time
ago.

AFAIK the incoming data will be processed inside the CDP prep stuff and
as there is one per RRA, these will behave differently for AVERAGE and
MAX RRAs. Am I wrong in this ?
