Total is a Ruby gem to detect the total amount of memory in the system.

First, install it:

$ gem install total

Then, use it like this:

require 'total'
puts Total::Mem.new.bytes

The following platforms are supported:

MacOSX
Linux
FreeBSD
~~Windows~~ (help needed)

If the platform is not recognized or is not supported, Total::CantDetect exception will be raised. You should catch it and proceed accordingly, for example:

def total_mb
  Total::Mem.new.bytes / (1024 * 1024)
rescue Total::CantDetect
  512
end

This code will return the actual memory size in Mb, if it can be detected, or 512 otherwise.

That's it.
