+  # By default, Rollbar will try to call the `current_user` controller method
+  # to fetch the logged-in user object, and then call that object's `id`
+  # method to fetch this property. To customize:
+  # config.person_method = "my_current_user"
+  # config.person_id_method = "my_id"
+
+  # Additionally, you may specify the following:
+  # config.person_username_method = "username"
+  # config.person_email_method = "email"
+
+  # If you want to attach custom data to all exception and message reports,
+  # provide a lambda like the following. It should return a hash.
+  # config.custom_data_method = lambda { {:some_key => "some_value" } }
+
+  # Add exception class names to the exception_level_filters hash to
+  # change the level that exception is reported at. Note that if an exception
+  # has already been reported and logged the level will need to be changed
+  # via the rollbar interface.
+  # Valid levels: 'critical', 'error', 'warning', 'info', 'debug', 'ignore'
+  # 'ignore' will cause the exception to not be reported at all.
+  # config.exception_level_filters.merge!('MyCriticalException' => 'critical')
+  #
+  # You can also specify a callable, which will be called with the exception instance.
+  # config.exception_level_filters.merge!('MyCriticalException' => lambda { |e| 'critical' })
+
+  config.exception_level_filters.merge!("ActionController::RoutingError" => "ignore")

+  # Enable asynchronous reporting (uses girl_friday or Threading if girl_friday
+  # is not installed)
+  # config.use_async = true
+  # Supply your own async handler:
+  # config.async_handler = Proc.new { |payload|
+  #  Thread.new { Rollbar.process_from_async_handler(payload) }
+  # }

+  # config.use_sucker_punch
+
+  # Enable delayed reporting (using Sidekiq)
+  # config.use_sidekiq
+  # You can supply custom Sidekiq options:
+  # config.use_sidekiq 'queue' => 'default'
+
+  # If your application runs behind a proxy server, you can set proxy parameters here.
+  # If https_proxy is set in your environment, that will be used. Settings here have precedence.

+  # If you run your staging application instance in production environment then
+  # you'll want to override the environment reported by `Rails.env` with an
+  # environment variable like this: `ROLLBAR_ENV=staging`. This is a recommended
