you can set the log level on the appender individually:

  logger = Logging::Logger['example_logger']
  logger.add_appenders(
    Logging::Appenders::Stdout.new(nil, :level => :info),
    Logging::Appenders::File.new('example.log')
  )
  logger.level = :debug

but note that you can only set *higher* thresholds on the appenders,
events below the log level of the superordinate logger instance
won't be passed through to the appenders, AFAIK. tim, please correct
me if i'm wrong ;-)

cheers
