Intel(r) Performance Counter Monitor: PCIe Bandwidth Monitoring Utility
This utility measures PCIe bandwidth in real-time
PCIe event definitions (each event counts as a transfer):
PCIe read events (PCI devices reading from memory - application writes to disk/network/PCIe device):
PCIePRd - PCIe UC read transfer (partial cache line)
PCIeRdCur* - PCIe read current transfer (full cache line)
On Haswell Server PCIeRdCur counts both full/partial cache lines
RFO* - Demand Data RFO
CRd* - Demand Code Read
DRd - Demand Data Read
PCIeNSWr - PCIe Non-snoop write transfer (partial cache line)
PCIe write events (PCI devices writing to memory - application reads from disk/network/PCIe device):
PCIeWiLF - PCIe Write transfer (non-allocating) (full cache line)
PCIeItoM - PCIe Write transfer (allocating) (full cache line)
PCIeNSWr - PCIe Non-snoop write transfer (partial cache line)
PCIeNSWrF - PCIe Non-snoop write transfer (full cache line)
ItoM - PCIe write full cache line
RFO - PCIe partial Write
CPU MMIO events (CPU reading/writing to PCIe devices):
UCRdF - read from uncacheable memory, including MMIO
WCiL - streaming store (partial cache line), includes MOVDIRI
WCiLF - streaming store (full cache line), includes MOVDIR64
PRd - MMIO Read [Haswell Server only] (Partial Cache Line)
WiL - MMIO Write (Full/Partial)

For non-CSV mode delay < 1.0s does not make a lot of practical sense. Default delay 1s is used. Consider to use CSV mode for lower delay values

But good to know that we have good support on Intel.
