I've been porting some real-time programs from Solaris to Linux. I've re-implemented the necessary code to set scheduling classes and priorities (and made some assumptions for mapping the ranges for the different classes!).

What I'd really like to be able to do is check that the processes are running at the expected/set priorities using something like ps. But ps doesn't show the class and only shows priorities in terms of niceness (so I reckon what it is showing me at the moment is garbage - it certainly doesn't make sense!

Is there another tool like ps which will do this?

I will also eventually want an updating tool, like top or proctool (Solaris), so I can check the CPU performance of each process. I couldn't get procmeter to work, nor wmsysmon to install, if either of those are in fact suitable.

Thanks a lot for any and all help

top has loads of frontends that you can use but i don't know if you will find any other things that are like ps but show the priorites in the way you want. the kernel only know the niceness values AFAIK

try searching sourceforge.net or freshmeat.net of tucows.com

or google.com to see if there are any groups working on it

Thanks, I will look at the sites you mention (though I had looked at tucows before).

I have had one bit of success - somehow I had overlooked the existence of "kpm" wihtin the KDE desktop I am using. This does allow you to view scheduling class and appropriate priority! My next problem is that it cannot be logged...hence I will search the sites you have recommended.


Thanks again,

Bee

you can always get the source to kpm tho - the actual process-looking-up code is probably a relatively small part of the program.

Yes, I will look at the code, too!
