scheduler statistics visualization tool

This utility will process various scheduler related statistics (e.g. /proc/schedstat) such that the "busiest" stats (greatest delta) will bubble up to the top similar to the ubiquitous "top" utility. It can alternately be sorted by the stat's value, or by name. Stats can be inclusively or exclusively filtered based on reg-ex pattern matching.


schedtop <options>

 -h [ --help    ]         produces help message
 -p [ --period  ] arg     refresh period (default=1s)
 -i [ --include ] arg     reg-ex inclusive filter (default=".*")
 -x [ --exclude ] arg     reg-ex exclusive filter (default="^$")
 -s [ --sort    ] arg     sort-by: n=name, v=value, d=delta (default='d')

Press Cntrl-C to exit the utility
