Thanks for the tip, it's almost what I want.

FreeBSD:
$ sysctl kern.cp_time
kern.cp_time: 1797279 579339 1349174 128959 811149589

DragonFly:
$ vmstat -c 1 | tail -n 1 | awk '{ print $14,$15,$16 }'
675875492 705365686 1527141678

Unfortunately, there's no data for nice or interrupt. Time to dig into top
sources...
