I am quite new to pfmon and tried : # pfmon --system-wide sizeof=64 44 <press ENTER to stop session> Then started "tbench 8", and got a kernel panic after 6 seconds. I was using oprofile like this opcontrol --vmlinux=/path/vmlinux --start // doing some benchmarking... opreport -l vmlinux | head -n 40 What would be a working equivalent for perfmon2 based tools ?
