Subject RE: Sequence numbers for LoggingEvents
Date Thu, 06 Dec 2007 06:10:49 GMT
If I recall there was a sequence number added to loggingevent in the 1.3 codebase, but that
was taken out a while ago.

You can modify logging events before they're processed by appenders by using the org.apache.log4j.rewrite
package in the 'receivers' companion.

Create your own rewritepolicy implementation which adds a sequence number property to each
loggingevent, and then specify a rewriteappender which references your rewritepolicy implementation
and delegates to a regular appender.

Subject: Sequence numbers for LoggingEvents

I have an application that is likely to produce LoggingEvents on 
identical millisecond epochs.  Thus I also need a sequence number to 
unambiguously determine event order. 

Is there any facility by which I can also include a montonically 
increasing sequence number in the event?  I went back through the 
archives...seems some work was started here for 1.3, but was stopped?
