https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D212681 --- Comment #23 from rainer@ultra-secure.de --- Which event specifier should I use? I can't even run the sample: (freebsd11 </root>) 0 # pmcstat =E2=80=93S RESOURCE_STALLS.ANY -O out.pmcst= at sleep 10 pmcstat: [options] [commandline] Measure process and/or system performance using hardware performance monitoring counters. Options include: -C (toggle) show cumulative counts -D path create profiles in directory "path" -E (toggle) show counts at process exit -F file write a system-wide callgraph (Kcachegrind format)= to "file" -G file write a system-wide callgraph to "file" -M file print executable/gmon file map to "file" -N (toggle) capture callchains -O file send log output to "file" -P spec allocate a process-private sampling PMC -R file read events from "file" -S spec allocate a system-wide sampling PMC -T start in top mode -W (toggle) show counts per context switch -a file print sampled PCs and callgraph to "file" -c cpu-list set cpus for subsequent system-wide PMCs -d (toggle) track descendants -e use wide history counter for gprof(1) output -f spec pass "spec" to as plugin option -g produce gprof(1) compatible profiles -k dir set the path to the kernel -l secs set duration time -m file print sampled PCs to "file" -n rate set sampling rate -o file send print output to "file" -p spec allocate a process-private counting PMC -q suppress verbosity -r fsroot specify FS root directory -s spec allocate a system-wide counting PMC -t process-spec attach to running processes matching "process-spec" -v increase verbosity -w secs set printing time interval -z depth limit callchain display depth --=20 You are receiving this mail because: You are the assignee for the bug.=
