Rack::Perf

This Rack middleware will time and record status codes from your controllers. It will then send up this timing data to Perf's logging infrastructure where metrics and alerts are generated.

Installation

• Add this line to your application's Gemfile:

  gem 'rack-perf'
  

• And then execute:

  bundle
  

• In your application.rb file, add the middleware in your application class

  module Example
    class Application < Rails::Application
      # ADD THIS LINE INTO THE APPROPRIATE MODULE
      config.middleware.use Rack::Perf, api_key="PERF_API_KEY"
    end
  end
