+
+  # Agent Enabled (Ruby/Rails Only)
+  # Use this setting to force the agent to run or not run.
+  # Default is 'auto' which means the agent will install and run only
+  # if a valid dispatcher such as Mongrel is running.  This prevents
+  # it from running with Rake or the console.  Set to false to
+  # completely turn the agent off regardless of the other settings.
+  # Valid values are true, false and auto.
+  # agent_enabled: auto
+
+  # Application Name
+  # Set this to be the name of your application as you'd like it show
+  # up in New Relic.  New Relic will then auto-map instances of your application
+  # into a New Relic "application" on your home dashboard page. If you want
+  # to map this instance into multiple apps, like "AJAX Requests" and
+  # "All UI" then specify a semicolon-separated list of up to three
+  # distinct names.  If you comment this out, it defaults to the 
+  # capitalized RAILS_ENV (i.e., Production, Staging, etc)

+  # The newrelic agent communicates with the New Relic service via http by

+  # asynchronously to the threads that process your application code,
+  # so it should not impact response times.

+
+  # EXPERIMENTAL: enable verification of the SSL certificate sent by
+  # the server. This setting has no effect unless SSL is enabled
+  # above. This may block your application. Only enable it if the data
+  # you send us needs end-to-end verified certificates.
+  #
+  # This means we cannot cache the DNS lookup, so each request to the

+  monitor_mode: false
+
+# Turn on the agent in production for 24x7 monitoring.  New Relic
