A way to see the scheduling of a process on linux?

There's a very good chance I missed this, but I didn't see how to check how a process is scheduled in linux. Whether the process/thread has been setup to use round robin, fifo, other, etc, scheduling. https://man7.org/linux/man-pages/man7/sched.7.html

It terms of scheduling / priority pstuil.Process class provides:

• nice() (process priority)
• ionice() (IO priority)
• cpu_affinity() (run process on a certain set of CPUs only)

Some of these overlap with the sched stuff in the os module:
https://docs.python.org/3/library/os.html#interface-to-the-scheduler
...so I believe you're looking for those ones instead. At the moment psutil won't let you handles fifos. etc.
It's something which could be included though. I've never investigated that part of the os module.

Yeah, I saw those other things, scheduling is conceptually nearby so I figured it was there somewhere. Thanks for pointing me to the os API, I admit that I didn't realize until this moment that os itself had so much :-). I do think access to the scheduling for a process would be nice, it seems relatively straightforward insofar as just calling to the underlying function. If you're interested in adding such I could leave this open, otherwise I can close. Cheers!

I think all the sched-related stuff is already provided by the above functions, which basically overlaps with os.sched_* functions. Closing.
