Useful links

  • https://github.com/josevalim/rails-footnotes
    It displays footnotes in your application for easy debugging, such as sessions, request parameters, cookies, filter chain, routes, queries, etc.

  • https://github.com/engineyard/rails_metrics
    RailsMetrics is an engine that hooks into your application to listen ActiveSupport::Notifications and show you statistics about them. RailsMetrics uses threads to save those notifications in the database through an in-process Queue. You can see charts based on each request and see what queries, actions, templates rendering, etc. are slow.
