Hi All,
I have posted an update to schedtop (v0.3) which adds /proc/<pid>/schedstats and /proc/<pid>/sched stats to the mix.
Also note that there is a comprehensive filtering mechanism built into all versions of schedtop:
"-i <REGEX>" sets the *include* pattern, and
"-x <REGEX> sets the *exclude* pattern.
By default, -i is set to allow everything, and -x is set to exclude nothing. A common config for me is to use "-x sched_info" since those sched_info stats seem to always be moving rapidly and can cloud stats that are more interesting (to me, anyway).
Let me know if you have any questions. Comments/feedback are welcome
-Greg

Hi All,
I have released a new version (v0.5) which fixes a compile error on
some platforms (like Mandriva, RHEL, and opensuse-factory) that did not
like the usage of operator/ in boost::filesystem::path code. v0.5 is
now fully supported on all of the original platforms that v0.2 worked on.
