In the course of developing, debugging information is invaluable. But there are times when I don't want to see every possible debug message. So this requires debug levels. My question is: what guidelines you have used for determining what is logged at each debug level? I've been using numeric levels, with increasing numbers logging more data. The other end of the spectrum involves the use of text levels, such as "debug", "warning", "emergency". I'm leaning towards keeping numeric levels. But I'm interested in what other mongers have used. The issue is still open, so please convince me if you think your idea is better.
As for the actual logging mechanism, I plan to use Log::Dispatch::Config. It seems quite flexible and well designed. Flexibility is key, because on my home server I have access to the error log, while on my shared production host I have very limited access so a seperate file is easier. Thanks for all your ideas.
