Even better, I will ...

What most likely is happening here:

MRTG reads some counter.
Five minutes later, it reads the counter again.

MRTG calculates the average increase as follows:
  1) subtract the counter values
  2) subtract the time stamps
  3) divide the outcome of (1) by the outcome of (2)

Suppose your counter has grown with 100 and this happened in 300 seconds.
The calculation in (3) will be:  100 DIV 300 (so: it is an integer) and
this is rounded down to 0.  In other words: that 0 is correct.

How can you overcome this?  Look in config.txt for the "perminute" or
"perhour" option.  The default is (the non-existing) "persecond".
