Simplify memory profiling of your Ruby app!

Add memplify gem to Gemfile

gem "memplify", "~> 0.3.0"

Install gem

bundle install

Create initializer for memplify

# config/initializers/memplify.rb
require "memplify"

Memplify.configure do |configuration|
  configuration.access_token = "[ACCESS_TOKEN]"
end

Add memplify middleware for staging environment

# config/environments/staging.rb
Rails.application.configure do
  config.middleware.insert(0, Memplify::Middleware)
end

# config.ru
require "memplify"

Memplify.configure do |configuration|
  configuration.access_token = "[ACCESS_TOKEN]"
end

class Application
  def call(env)
    status  = 200
    headers = { "content-type" => "text/html" }
    body    = ["Kaboom!"]

    [status, headers, body]
  end
end

builder = Rack::Builder.new do
  use Memplify::Middleware if ENV["RACK_ENV"] == "staging"

  map('/') { run Application.new }
end

run builder

You can use memplify also in background jobs and in any place of your application by using reporter directly

Memplify.report("custom/profile", profile: ENV["ENVIRONMENT"] == "staging") do
  # Your code
end
