NewRelic service is great for application monitoring and errors tracking. However it doesn't track rake exceptions by default. You can use AirBrake gem and service, but sometimes it's too much for you. Fortunately with a bit of ruby it's easy to do it yourself.
Create a small module to hook into rake library at
module RakeNotifier def self.included(klass) klass.class_eval do alias_method :display_error_message_without_log, :display_error_message alias_method :display_error_message, :display_error_message_with_log end end def display_error_message_with_log(ex) ::NewRelic::Agent.notice_error(ex) display_error_message_without_log(ex) end end
And then hook it up in the rails initialiser
if defined?(::Rake) Rake.application.instance_eval do class << self include RakeNotifier end end end
That's it, now you will see rake exceptions at your NewRelic Errors view.
