Rack::Reqorder

Simple gem for monitoring Rack apps. Uses MongoDB. It can be used in combination with rack-reqorder-monitor.

Introduction

Simple gem that sits on top of Rack and records request/response statistics as well as monitors for exceptions. It saves everything in MongoDB and exposes a simple API for retrieving these data.

The API is very robust, built with the help of mongoid_hash_query.

Installation

Add this line to your application's Gemfile:

gem 'rack-reqorder'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rack-reqorder

Usage

Just add it on the middleware pipeline and initialize it.

For instance, in Rails, in an initializer add:

Rack::Reqorder.configure do |config|
  config.mongoid_yml = File.join(Rails.root, 'config', 'mongoid.yml')
end

Rack::Reqorder.boot!

Rails.application.config.middleware.insert_after(ActionDispatch::DebugExceptions , Rack::Reqorder::Logger)

#rack-cors also needed
Rails.application.config.middleware.insert_before 0, "Rack::Cors" do
  allow do
    origins '*'
    resource '*', :headers => :any, :methods => [:get, :post, :options]
  end
end

Please note that you can configure origins and resource depending on how you mount the rack-monitor engine and where you deploy your front-end.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release to create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
