Database triggers are a marvelous thing. Is this wrong? ((InOctetsCurrent-InOctetsLastTime)*8) --------------------------------- (TimeCurrent-TimeLastTime) = 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. ________________________________________ Robin
