its ancestor log4j:

• "Short introduction to log4j" by Ceki Gülcü, March 2002 [the proper link]
• log4j's wikipedia [link] with a nice and terse description
• Vipan Singla's article "Don't Use System.out.println! Use Log4j" [link]

Log::Log4perl lets you remote-control and fine-tune the logging behaviour of your system from the outside. It implements the widely popular (Java-based) Log4j logging package in pure Perl.

Log4perl is also compatible with log4j's graphical log analyser Chainsaw.
