Anyone who has managed a network knows that when you look at your
MRTG/Cacti graphs at 5min, 10min ,15min intervals - all looks well.
Start looking at 1sec intervals and you will see spikes that hit
100% of capacity - even on networks running at 25% average
utilization.

As sampling rate approaches zero, so will the "spikyness" of the
graph--ultimately an interface is either sending a frame (100%) or it's
not (0%).
