ActiveSupport::Notifications.subscribe(:render) {|*args| ...}

Raises an error if invalid event name type is passed:

end
@event = event
ActiveSupport::Notifications.subscribe(/render/) do |event|

it will yield an event object to the block:
If the block passed to the method only takes one parameter,

end
payload # => Hash, the payload
id # => String, unique ID for the instrumenter that fired the event
finish # => Time, when the instrumented block ended execution
start # => Time, when the instrumented block started execution
name # => String, name of the event (such as 'render' from above)
ActiveSupport::Notifications.subscribe('render') do |name, start, finish, id, payload|

The +block+ will receive five parameters with information about the event:

You can subscribe to events by passing a String to match exact event
