In a troubleshooting situation I think real time is valid. Off course, is non-sense doing this for "normal" monitoring... But firstly define: What's real-time? every second? miliseconds? 10 seconds? 30 seconds? It's subjective nowadays 2012/5/4 David Miller <dmiller () tiggee com>

Measurement of throughput is how many times this happens during a particular time interval. I hope I remembered right.I think you are referring to this thread - http://www.gossamer-threads.com/lists/nanog/users/149903 and in particular this quote: cjp at 0x1 wrote on Feb 16, 2012, 11:25am 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%). -cjp Utilisation doesn't "become 100%", instead measured utilisation will either be 100% or 0% at each interval. -DMM
