MethodMeter

MethodMeter is a library module that instruments methods defined in a given object. These methods are NOT from included or extended modules. These methods are also NOT from parent objects. By object, it means either a class or module.

Add this line to your application's Gemfile:

gem 'method_meter'

And then execute:

$ bundle

Or install it yourself as:

$ gem install method_meter

MethodMeter.observe Arithmeter

MethodMeter.measure!('key-1') do
  arithmeter = Arithmeter.new
  arithmeter.add 1, 3

  Arithmeter.sum 1, 3

  arithmeter = Arithmeter.new
  arithmeter.add 4, 3

  Arithmeter.sum 4, 3
end

ap MethodMeter.data
ap MethodMeter.measurement
