Rails 3 my custom BufferedLogger

I would like to define a custom logger for my Rails 3 app, in a way that it does not replace the original logger (I still make use of its information).

I assumed that I could define in a lib a class that inherited BufferedLogger as I've seen on some blogs. Then I would instantiate a variable to represent my logger, on the end of my application.rb with those lines:

require 'smart_logger.rb'
sl = SmartLogger.new("log/soccer.log")

And in my controller (as models and views) I would be able to use:

sl.warn("Tentativa #{session[:login_number]} de fazer login do IP#{request.remote_ip}, email:#{@user_session.try :email}, senha: #{@user_ses开发者_开发百科sion.try :password}. ")

My question is how can I achieve to have my custom logger available application wide and flushing properly? That would be sort of a parallel logger.

Better describing, its more like an User-Action-Logger, targeting Data Minning.

btw: I guess it has a great performance :)

Here is a gem that makes log output customization really easy in Rails3: https://github.com/johmas/itslog
