Dear Linux Perf Community:
In perf turtorial, it is said perf support per-thread information,
however, when doing java test, it seems doesn't work well.
Here is how I used perf:
$perf record -s java -cp . hellop ### in perf help, it is said -s
is per-thread mode.
$perf report -T
And in result I didn't see any per-thread information, I mean, there
should be some jit threads, some vm threads, some gc theads... etc,
but what I see is jit.so, vm.so, not per-thread information.
Does anyone knows if I used perf wrongly? Is there any other ways to
gather per-thread information in perf?
Thanks.
