All,
The MOle (originally a rails plugin) has been re-released as a gem . The MOle allows you to closely monitor how your users are interacting with your applications Whether you're releasing a new application or enhancing an existing ones, you might wonder how are your customers using your application ? Using the MOle you will be able to easily trap and record the way your various application features are being used. The MOle will also assist you in monitoring performance issues so you can catch them early before getting that phone call... Most importantly, you will now have necessary information to decide which features are worth tackling in your next iteration and whether your launch is a success or a bust.
The gem will work within your ruby application, Merb and Rails, etc...
The MOle is hosted on RubyForge and documentation and samples of 'MOled' application for various frameworks can be found at http://rubyforge.org/projects/mole.
Enjoy !
