Hi, thanks for creating the issue. Could you please also share the output of ``lscpu`` command?

Thanks, that is helpful. On your CPU we are disabling reading these RDT counters from HW due to errata. Linux kernel does the same: https://github.com/torvalds/linux/commit/d56593eb5eda8f593db92927059697bbf89bc4b3 But when booting the Linux...

could you please also share the complete output of "pcm -r -i=1" main utility (run exclusively to pcm-sensor-server or pqos)?

and also the output of "curl --silent http://localhost:9738/metrics | grep Memory_Bandwidth" when pcm-sensor-server is run exclusively?

yes..
