For parsing log4j files there are some alternatives:
Chainsaw (java gui). If the links dead, note that it should be part of log4j.
- Similar to chainsaw but in .net: logviewer.
Log2Console looks pretty sweet. It has some positive comments.
On the logviewer page you find a sample configuration for using "log4net.Layout.XmlLayoutSchemaLog4j". Note that the log4net xmllayout should be parse:able by logviewer as well.
can log to the log4j layout.
