How to define time intervals in a Rails application?

Question

I have a Rails application running on 4.1.6 and Ruby 2.1.3. Several times, according to some requests, they take so much time, but this does not always happen. When I check newrelic, I still cannot identify or trace the slowness lines.

Answer 1

check perftools - you can use googles perftools or ruby specific implementation . There is a good entry about it here.

Answer 2

API.

Doorkeeper::TokensController#create

module Doorkeeper
  class TokensController < Doorkeeper::ApplicationMetalController
    def create
      response = strategy.authorize
      self.headers.merge! response.headers
      self.response_body = response.body.to_json
      self.status        = response.status
    rescue Errors::DoorkeeperError => e
      handle_token_exception e
    end

  # ...snip...

    private

    def strategy
      @strategy ||= server.token_request params[:grant_type]
    end
  end
end
