Module: ActionController::Instrumentation
Overview
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.
