This is a FAQ.
You need the 'gauge' option.
Here's an extract from
Treat the values gathered from target as 'current status'
measurements and not as ever incrementing counters. This would be
useful to monitor things like disk space, processor load, temperature,
and the like ...
In the absence of 'gauge' or 'absolute' options, MRTG treats
variables as a counters and calculates the difference between the
current and the previous value and divides that by the elapsed time
between the last two readings to get the value to be plotted.
As expected, MRTG is graphing the value of (66 - 66) / 300
for you. This is indeed always zero.
