The problem with MRTG is that it works only on integers.  If anything
less than 1 is computed, it is truncated to zero.

RRDtool does not have this problem.  It will autoscale and produce
a graph that can show *very* low numbers.

Of course, trying to graph 1/3600 per second (which is 1 per hour)
next to 10 per second will render the first value invisible.
