Hello all,
I'm wondering if there is currently a way to monitor the throughput of a
PCIe lane or group of lanes associated with a device ?
I've done a little exploring of the source and man pages but have yet to
find anything that seems to relate in an obvious form.
I wonder if netgraph could somehow be used for this ?
Thanks,

unfortunatly PCIe traffic occurs at a level below that at which
the OS can really monitor.
there would have to be some hardware support I think.
THEORETICALLY you could get every device driver to report back
how much traffic it has sent to each device and you could aggregate
that by bus bt it would be a lot of work and overhead
ad wouldn't really be agood measure of burst throughput...
