Description

A Ruby interface for getting memory information.

Supported Platforms

• Linux
• Windows
• OSX
• BSD

Note that only DragonflyBSD has been tested. I am not sure about other flavors yet.

Installation

gem install sys-memory

Adding the trusted cert

gem cert --add <(curl -Ls https://raw.githubusercontent.com/djberg96/sys-memory/main/certs/djberg96_pub.pem)

Synopsis

require 'sys-memory'

p Sys::Memory.memory                # Hash of all information

p Sys::Memory.total                 # Total memory, no swap
p Sys::Memory.total(extended: true) # Total memory, include swap

There's also the free, used and load module methods.

Notes

I realize there are some philosophical differences about what constitutes "available memory". I've tried to accomodate both of the common approaches to it that I saw debated online. In short, you can choose to include swap memory as part of memory calculations or not as you see fit via an optional argument.

You can also just use Sys::Memory.memory and collate the various hash data pieces as you see fit.
