ThunderX2 interconnect metrics

YHuerta

Hi,

I was wondering if there are any metrics I can use to track the performance of the CCPI2 interconnect. Intel has two metrics in some of its CPUs: UPI bandwidth and UPI utilization outgoing. I'm using CentOS 8 and the perf tools has the following events available: data_pktsent, gic_pktsent, req_pktsent and snoop_pktsent. are there any performance metrics i can compute using these performance counters? 

thanks,

YAH
