#controller_name ⇒ Object

If the controller name segments look like a file path, convert it to the controller class name. If it begins with a capital letter, assume it’s already a class name. We only expect a lower case letter with Rails, so we’ll be able to use camelize for that.

end

#cpu_metric ⇒ Object

return the cpu measuring equivalent. It may be nil since this metric was not present in earlier versions of the agent.
