struct

Hardware::Net

Inherits Struct / Value / Object

Network informations about the system or a process like the brandwidth use.

Example of network brandwidth calculation:

net = Hardware::Net.new # System network stats
old_in, old_out = net.in_octets, net.out_octets
loop do
  sleep 1
  net = Hardware::Net.new # Update network stats
  now_in, now_out = net.in_octets, net.out_octets
  puts "down: #{(now_in - old_in) / 1000}kB/s | up: #{(now_out - old_out) / 1000}kB/s" # => down: 427kB/s | up: 24kB/s
  old_in, old_out = now_in, now_out
end

Constructors

new(pid : Int64 | Nil = nil)

Creates a new Hardware::Net for the system, or a given PID.
