OK. I'll bite. On your 5-min aggregate graphs, you show the following numbers: Max In: 184.8 Mb/s (6.6%) Average In: 41.9 Mb/s (1.5%) Current In: 44.1 Mb/s (1.6%) Max Out: 84.7 Mb/s (3.0%) Average Out: 56.5 Mb/s (2.0%) Current Out: 57.2 Mb/s (2.0%) How is it that in an exchange fabric, you're showing 13.1Mb/s difference between what it put into the fabric and what is going out of the fabric for this poll and 100.1Mb/s over the past 32 hours? Perhaps I'm missing something but, it is my understanding that exchange points provide a fabric for peers to exchange traffic. By that simple definition, when one peer sends traffic out it's exchange point interface, it's destined for another peer on the fabric and the numbers for IN/OUT of the fabric will be REAL close to identical. (I understand that with 5-min polling, they don't always jive perfectly but, I've never seen them be that far out of whack!) --- John Fraizer EnterZone, Inc CMH-IX http://www.cmh-ix.net/ On Tue, 5 Jun 2001, Jim Mercer wrote:

I guess I can better answer that. One of the members ports wasn't being added for the graph which has now been corrected. If you look at the historical data, before the middle of week 21, you will see what you were expecting. The switch and interface numbers changed during week 21 which caused a little disruption in the graphing. Joel
