args i use

-XX:+FlightRecorder
-XX:+FlightRecordingDumpOnUnhandledException -XX:StartFlightRecording=duration=6m,filename=member.jfr"
-XX:FlightRecorderOptions=loglevel=debug,delay=2m,maxsize=2g"
error
Unrecognized VM option 'FlightRecordingDumpOnUnhandledException'
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
what is the correct option to use ? to dump the recording on exception
-XX:+FlightRecordingDumpOnUnhandledException only works for JRockit. No similar option exists for Hotspot (JDK7/8)
Use the template manager that is available in Mission Control.
Go to Windows -> Template Manager and import the template and check Heap Statistics and Allocation Profiling, export it. Done!
(I copy-pasted this text from similar question , @Kire wrote it as well)
Basically, you can just add exception-level=all
to settings. I have no idea why Oracle don't have documentation for this parameters.
