There is this example of profiling threads; don't know if it has all you want, but you could modify it so that it does.

The field code for processor usage is "c". Possible values are: - not reported TS SCHED_OTHER FF SCHED_FIFO RR SCHED_RR ? But in this post we shall mostly focus on the unix style syntax. The reason is not that they’re not doing their job or wasting their time - it is mostly because they have automated a good deal of their routine tasks.
This selects the processes whose effective group name or ID is in grouplist. See the -f option, which -F implies. -O format is like -o, but preloaded with some default columns. As in the example above. How To Check Which Process Is Using More Cpu In Linux Aaron Kili says: @Buchan Thanks for the useful insights.

The "+" is optional since default direction is increasing numerical or lexicographic order. http://computerhelpdev.com/cpu-usage/solaris-view-process-cpu-usage.php But the above ps command sorts in a more simpler manner, taking 1 column at a time (like school maths).
