The psutil code was not too hard to port to Julia:

```julia
idle_time(info::Sys.CPUinfo) = Int64(info.cpu_times!idle)

busy_time(info::Sys.CPUinfo) = 
	Int64(
		info.cpu_times!user +
		info.cpu_times!nice +
		info.cpu_times!sys +
		info.cpu_times!irq
	)

period = 3 # seconds

usages = let
	
	info = Sys.cpu_info()
	busies = busy_time.(info)
	idles = idle_time.(info)

	sleep(period)

	info = Sys.cpu_info()
	busies = busy_time.(info) .- busies
	idles = idle_time.(info) .- idles

	busies ./ (idles .+ busies)
end

# This returns a Vector{Float64} with the CPU usage between 0.0 and 1.0

```
