Overview

# Action Controller Instrumentation

Adds instrumentation to several ends in ActionController::Base. It also provides some hooks related with process_action. This allows an ORM like Active Record and/or DataMapper to plug in ActionController and show related information.

Check ActiveRecord::Railties::ControllerRuntime for an example.
