A basic module to get CPU, memory and network informations of the current running OS and its processes.

Tested on Linux.

Add this to your application's shard.yml:

dependencies:
  hardware:
    github: crystal-community/hardware

The documentation is accessible at https://crystal-community.github.io/hardware.

It is generated with crystal docs in the gh-pages branch.

require "hardware"

memory = Hardware::Memory.new
memory.used         #=> 2731404
memory.percent.to_i #=> 32

cpu = Hardware::CPU.new
pid_stat = Hardware::PID.new.stat            # Default is Process.pid
app_stat = Hardware::PID.new("firefox").stat # Take the first matching PID

loop do
  sleep 1
  p cpu.usage!.to_i          #=> 17
  p pid_stat.cpu_usage!      #=> 1.5
  p app_stat.cpu_usage!.to_i #=> 4
end

You can run the specs in a Docker container:

$ docker-compose up
$ docker-compose run spec
