I have a process (jackd) that runs several threads. One of the threads it runs should be in realtime, the others run on normal priorities. I'd like to check if it actually runs on realtime. What program can I use for this task?

You can use ps with the -m switch to show all threads, and -l ("long" format) to show the priority. The full command would look like:

ps -m -l [TASK PID]

Cool, didn't know about the -m switch! It seems it is also possible to list all threads with their realtime priorities (if available) with something like ps -eO rtprio -m. – Turion Aug 1 '12 at 15:42
