But I'm interested in your subject. What about trying 'pstree' $ pstree -p <example output> |--events/0(3)--|-aio/0(44) |-kacpid(5) |-kblockd/0(31) |-khelper(4) |-pdflush(41) |-pdflush(42) <example output> Then take the pid's and use top to monitor them. $ top -p3,44,5,31,4,41,42 I don't know if the subtrees will show you anything, but maybe worth a try.
