We will talk about introspection features of Ruby interpreter (MRI) to solve troubles on your Ruby on Rails application. Rails application development with Ruby is basically fast and easy. However, when you have trouble such as tough bugs in your app, performance issues and memory consumption issues, they are difficult to solve without tooling. In this presentation, I will show you what kind of introspection features MRI has and how to use them with your Rails application.
