Example of what I'd like to have happen with logging

log_extender.rb

class LoggerKhan < Logger
  def add(severity, message = nil, progname = nil)
    return super unless severity == 'info' && "#{message}" =~ /some_tag/
    redis_logger.add(severity, message, progname)
  end
  
  private
  
  def redis_logger
    @redis_logger ||= Logger.new Rails.root.join('log', "redis_#{Rails.env}.log")
  end
end
