How about something like this?

class CustomLogger
  def initialize(*args)
    @logger = Logger.new(*args)
  end

  def method_missing(name, *args)
    case :debug, :info, :warn, :error, :fatal, :unknown
      @logger.send name, formatter(*args)
    else
      @logger.send name, *args
    end
  end

  def formatter(log_zone, msg)
    # Do your formatting here
    ...
  end
end
