Simple profiler that take concatenation of jstack's output as input. It's useful, when you want to find what's going on a production server that you can't stop or profile (with classic profiler).
How to use
First generate an full thread dump output every n seconds (60 sec in this example), append those thread dump in a file (jstack.log in this example). Ctrl+C to terminate
$ while true ; do jstack PID >> jstack.log ; sleep 60 ; done
Then launch the analyze with:
$ sbt "profiler jstack.log"
