log4j

log4j and associated logging facilities might be useful to look at while developing this.

The monolog product that has been mentioned was obviously heavily influenced by log4j and it's descendants. Separating the concerns of gathering log event information, formatting the information and outputting the formatted record to storage should definitely be considered.

One feature of log4j that monolog is missing is the idea of a hierarchy of loggers. I'd like to see something like that in MediaWiki eventually but pushing for it in the initial implementation may be overreaching.
