Well, not.

More like the performance counters in the CPU, but also some for the
chipset so you could get information about bus transfers and traffic,
kind of like CPU performance monitoring can show you memory accesses and
other CPU activity.

Then generate a summary to help you see where your system needs work.

Things like utilization of PCI bus, CPU->chipset, CPU->memory, PCIe
lanes and bandwith per lane, chipset->PCI, chipset->PCIe...

That sort of thing.
