for FreeBSD which queries kern.cp_time via sysctl.
But on DFlyBSD I get: sysctl: unknown oid 'kern.cp_time'.
What is the best way of doing this?
Use (8)iostat.

losalamos:...sources/src/sys$ iostat -C -t proc -d
           cpu
us ni sy in id
14  0  6  2 78
It's the same info as kern.cp_time used to give.
Well it is not the *same* but good enough.
kern.cp_time is an always incrementing number and should be stored as 
DERIVE in rrdtool

iostat gives percentage as a result, so this sophisticated algorithm is 
not needed. It can be stored as GAUGE.

Thanks that's the thing I was looking for!
