As another poster pointed out, all of the FreeBSD programs (top, vmstat,
xosview, ktop) get this stuff from kvm - which is a non portable (across
different versions of FreeBSD) interface. FreeBSD also doesn't keep
these numbers on a per CPU basis on a SMP box.
I wrote a patch for fixing the SMP case and a KLD to get them via
sysctl. With slight modifications to the KLD, you can get those values
exported via sysctl.
The KLD is available at:
