Thanks for all the replies! Nick, counting traffic on inter-switch links is kind of cheating, isn't it? I mean if "input bytes" and "output bytes" on all the ports facing the IX members are already counted, then counting traffic on links between the switches in fabric will count some of the traffic multiple times. Patrick, how does smaller sampling period help to show more traffic volume on switch fabric? Or do you mean that in case of shorter sampling periods the traffic peaks are not averaged out and thus peak in and peak out traffic levels remain higher? regards, Martin On 9/17/13, Nick Hilliard <nick () foobar org> wrote:

Which is probably why no serious IXP does it.It's not silly - it's just not what everyone else does, so it's not possible to directly compare stats with other ixps. I'm all in favour of using short (but technically sensible) sampling intervals for internal monitoring, but there are good reasons to use 300s / ingress sum for prettypics intended for public consumption.
