[PATCH procd] ubus: add state measurement

[Florian Eckert]

Hello Christian


> I wonder if this kind of thing should be under a config flag?

I do not see under system, with the command 'ubus -v list system'
a section 'config'. I do not wanted to add a new section, so I
decided to implement it under 'info' because this are runtime
information as 'load', 'memory' ...

> Like I feel these kind of stats may be needed only for debug purpose?

I do not use it only for debug purpose, but also for tracking changes on
boot when  enabling new services in production. I also use this for some
function on my system to check if we have finished booting completly.

If it doesn't matter from your point of view whether we leave it there 
or
move it somewhere else, then I plead that we leave it as it is. 
Otherwise,
as already mentioned above, we would have to introduce a new function 
section
under 'system', because all other sections unter 'system' have nothing 
to
do with it.

Best regards
