Linux System Info is a gem that allows you to get information about you're linux computer. It retrieves information such as CPU, RAM, Hard drive etc. This works only for your local computer and for Linux Debain or Redhat based operating system.
The following utility is needed to get a list of devices connected to the PCI bus.
Debain based Linux
sudo apt-get install pciutils sysstat net-toolsRedHat based Linux
sudo yum install pciutils sysstat net-toolsAdd this line to your application's Gemfile:
gem 'LinuxSystemInfo'And then execute:
$ bundle
Or install it yourself as:
$ gem install LinuxSystemInfo
