[Beowulf] detection and diagnosis of PCI bus saturation

Does anybody here have any thoughts, experiences, or references
to diagnostic methods when looking into potential PCI bus saturation?

If one is moving data across the bus, either under CPU copies or under
DMA/bus master, are there canonical methods to detect, perhaps
in bridge chip registers or other, the state and/or counts of
bus collisions and/or saturation?

Your help would be greatly appreciated. Thanks.
