Hi, I would like to count hardware events such as instructions retired / unhalted-core-cycles for all the systems for BOTH OS and APPLICATION. I am aware that pmcstat has a system wide monitoring mode that counts events across all the CPUs for all processes. I want to know whether the statistics for kernel code are collected as well ? (which I dont think so). Thanks!
