Is there a way to get percent CPU usage (or any other resource usage ) from JDB? So if I suspect that one task has run amok and is monopolizing the CPU I can search for it using JDB.
CPU usage is not directly possible with jdb as jdb only has a current view with the system being stopped. What usually works quite ok is to check for 'ready' threads (with 'lp' jdb command) a couple of times and see if one or some are ready besides the kernel idle threads all the time.
