#logs_to(name, opts = {}) ⇒ Object

Options

  • :write_mode - mode used when opening the log file. You’ll ususually just want ‘a’ for append or ‘w’ for overwrite. Defaults to ‘a’.

  • :shift_age - Number of old logs to keep or frequency of rotation.

  • :shift_size - Maximum logfile size that only applies when :shift_age is a number.

  • :progname - Logging program name. The :progname value is used in the default logging format if defined.

Examples

class Publisher
  include Logit

  logs_to "/tmp/publisher.log"

  def do_it
    logger.info("doing something")
  end
end

class Publisher2
  include Logit

  logs_to :publisher, :progname => "Publisher #{Process.pid}"
                      :shift_age => 'daily'
  def do_it
    logger.info("doing something")
  end
end
