And what exactly is sysmon?

$ apropos sysmon
powerd (8) - power management daemon for sysmon

And powerd doesn't reference it further.

I see it in src/sys/dev/sysmon, but its hard to know what it should
be unless it's documented.  envsys still has the "This API is
experimental and may be deprecated at any time" note on it and:

BUGS
     This entire API should be replaced by a sysctl(8) interface or a kernel
     events mechanism, should one be developed.

So, since you have been involved in sysmon development, it would be
helpful to know where you see it going/growing.

I like a couple of the aspects of cpufreq(9) in Linux, but I'd like
to see something tied into the things that sysmon has under its
control.  I haven't yet looked to see what, if anything, any other
BSD is doing in this area.

Can you help get some of this straightened out?
