Introduce a new option to dump trace output to files named by the monitored events and update perf-script documentation accordingly. Shown below is output of perf script command with the newly introduced option. $ perf record -e cycles -e cs -ag -- sleep 1 $ perf script --per-event-dump $ ls perf.data.cycles.dump perf.data.cs.dump Without per-event-dump support, drawing flamegraphs for different events would require post processing to separate events. You can monitor only one event at a time if you want to get flamegraphs for different events. Using this option, you can get the trace output files named by the monitored events, and could draw flamegraphs according to the event's name.
