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

Tested on Linux.

## Installation

Add this to your application's `shard.yml`:

```yaml
dependencies:
  hardware:
    github: crystal-community/hardware
```

## Documentation

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

It is generated with [crystal docs](https://crystal-lang.org/docs/conventions/documenting_code.html) in the `gh-pages` branch.

## Examples

```crystal
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
```
## Development
