This is a lightweight library that wraps access to the data in /proc/meminfo found in many linux variants, which contains live memory usage information about a machine.

Install the gem:

gem install mem_info

Require the library like you would expect:

require 'mem_info'

Then create a new MemInfo object:

m = MemInfo.new
m.memtotal     => 70000
m.memfree      => 54300
m.memused      => 15700
m.free_buffers => 75000

Take a look in lib/mem_info.rb for all fields that are available.
