Looks ok - these are counter type data sources - snmpget won't show you
explicit traffic values, if that's your problem. Counters are always
incrementing and mrtg calculates traffic here by measuring differences
between read counter values and dividing it by number of second in
configured interval. I think it's described somewhere on the MRTG
