I don't know of any IXP that does this. Industry standard is as
you and others wrote before: the 5-minute counter difference on
all customer-facing ports, publishing both input and output bps
and pps. I guess MRTG is to 'blame' for these values more than
anything.
Serious question, at an IXP shouldn't IN = OUT nearly perfectly?
Ding ding ding! And that's why honest IXPs graph both, to show that
they have no packet loss on their inter-switch links.
(Or, much more likely, measurement errors due to wrong config for the
grapher)
