Database triggers are a marvelous thing. Is this wrong?
((InOctetsCurrent-InOctetsLastTime)*8)

(TimeCurrent-TimeLastTime) =3D Inbound bits/sec
We chose this because it doesn't matter if it is 30 seconds or 8 minutes
between sample points, it is all normalized in that period. I do
realize that it is an average within that window, but all we need to do
is tune the cron job (how often we poll) to increase resolution.
