Concept

scheduler statistics visualization tool

This utility will process statistics from /proc/schedstat such that the busiest stats will bubble up to the top. It can alternately be sorted by the largest stat, or by name. Stats can be included or excluded based on reg-ex pattern matching.

Usage

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')


Kernel Configuration

You need to enable the scheduler statistics in your .config. This utility will only work with v14 of the stats (current as of this writing)
