Retire your debugger, log smartly with Log::Log4perl! (O'Reilly)

[Posted September 18, 2002 by cook]

Michael Schilli explains the Log::Log4perl Perl logging package on O'Reilly. "You've rolled out an application and it produces mysterious, sporadic errors? That's pretty common, even if fairly well-tested applications are exposed to real-world data. How can you track down when and where exactly your problem occurs? What kind of user data is it caused by? A debugger won't help you there. And you don't want to keep track of only bad cases. It's helpful to log all types of meaningful incidents while your system is running in production, in order to extract statistical data from your logs later."
