PCI/IO Bandwidth

[jramasam123]

Hi, I ran pcm and my cpu is:
Intel(R) Xeon(R) W-10885M CPU @ 2.40GHz, cpu model = 165 (I believe it is comet lake). It is a one socket workstation laptop. When I run pcm-pcie, pcm-iio, it says not supported cpu. Is it possible to get IO/PCIe utilization/bandwidth in this system from
PCM OR any other utility (I'm using windows 10 server OS). I've a PCIe GPU card and I need to know how much data is sent to/from it.
Thanks, Jay

I think the closest is the "IO" bandwidth metric in pcm.exe

Thanks for the prompt response. I guess, I can not use PCM for my need.

The IO metric is based on the UNC_IMC_DRAM_IO_REQUESTS counter documented here:
https://software.intel.com/content/www/us/en/develop/articles/monitoring-integrated-memory-controller-requests-in-the-2nd-3rd-and-4th-generation-intel.html

The traffic from/to the integrated graphics ("GT engine") is a separate category counted in UNC_IMC_DRAM_GT_REQUESTS.

the IO metric includes PCIe read/writes to main memory controller but does not include other components of the PCIe traffic (for example read/write from CPU caches).
