# The priority is based upon order of creation: first created -> highest priority.
# See how all your routes lay out with "rake routes".
# You can have the root of your site routed with "root"
# root 'welcome#index'
# Example of regular route:
# get 'products/:id' => 'catalog#view'
# Example of named route that can be invoked with purchase_url(id: product.id)
# get 'products/:id/purchase' => 'catalog#purchase', as: :purchase
# Example resource route (maps HTTP verbs to controller actions automatically):
# resources :products
# Example resource route with options:
# resources :products do
# member do
# get 'short'
# post 'toggle'
# end
#
# collection do
# get 'sold'
# end
# end
# Example resource route with sub-resources:
# resources :products do
# resources :comments, :sales
# resource :seller
# end
# Example resource route with more complex sub-resources:
# resources :products do
# resources :comments
# resources :sales do
# get 'recent', on: :collection
# end
# end
# Example resource route with concerns:
# concern :toggleable do
# post 'toggle'
# end
# resources :posts, concerns: :toggleable
# resources :photos, concerns: :toggleable
# Example resource route within a namespace:
# namespace :admin do
# # Directs /admin/products/* to Admin::ProductsController
# # (app/controllers/admin/products_controller.rb)
# resources :products
# end

Based on the error you're getting, it looks like you're trying to access the route to the New Relic Ruby agent's developer mode in your staging and production environments. Developer mode installs a middleware in your app that responds to any URL prepended with /newrelic. Because you've enabled Developer mode in your development (localhost) environment (the developer_mode key is set to true in your newrelic.yml under development), accessing this route succeeds there, but it fails in staging and production because you don't have developer mode enabled in those environments.
Your current configuration is usually desirable, since Developer mode introduces a large amount of overhead that is generally unacceptable in production. Rather than attempt to access the route in staging or production, use it during development only.
You may also want to consider upgrading the version of the agent you are using, since version 3.5.7 does not fully support Ruby 2.0 or Rails 4. More information on releases can be found at https://docs.newrelic.com/docs/releases/ruby.
