If I understand what you're saying you see this in your logfile:

timestamp  value  value
timestamp  0 0 0 0
timestamp  0 0 0 0
and so on


If that is true, you are probably measuring something that is not
incrementing a lot.  Remember that MRTG measures >per second< and
thus the increase your counter has will be divided by 300.  MRTG
works with integers and anything below 1 (per second) will end up
as zero.

Things to try are the "perminute" and "perhour" options.
