logging version 0.9.0 by Tim P. [http://logging.rubyforge.org/](http://logging.rubyforge.org/) (the “Monkeyful Chimptacular” release) == DESCRIPTION Logging is a flexible logging library for use in Ruby programs based on the design of Java’s log4j library. It features a hierarchical logging system, custom level names, multiple output destinations per log event, custom formatting, and more. == CHANGES 2 minor enhancement - Exceptions from appenders are captured and logged - Internal logger for the Logging framework (disabled by default) - Added a DSL configuration format (more readable than YAML) 1 bug fix - Modules could not have their own logger instance Blessings, TwP ---

If your logger level is set to ‘error’ then only error and fatal log events will be propagated to the appenders. But you can configure appenders individually to drop log events below a certain threshold. For the example above … Logging::Appender[‘stdout’].level = :info Logging::Appender[‘exmaple.log’].level = :debug And you would need to set the logger level to :debug to see any difference between the output of the two appenders. logger.level = :debug Just FYI – you can access an Appender or Logger by name if they have already been created: Logging::Logger[‘example\_logger’] #=\> always returns the same logger instance Logging::Appender[‘stdout’] #=\> always returns the stdout appender if it has been created Blessings, TwP
