Get Total Memory Size

This Ruby gem helps you 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 (including MSYS2/MinGW, MSVC, and Cygwin environments)

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

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

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

That's it.
