Dear all,

I am currently using log4j as my logging system. I am curious if log4j can generate dynamic log file. As you know log4j.properties can allow users to set up various of setting. Stupid me tried to imagine the following can be valid:

log4j.appender.myApp.File=c:/%d{ISO8601}.log

Unfortunately, that just act like static log file. I just want to know is there any dynamic way to generate dynamic logger? Such as 20060313085033.log, or 20060313185533 ? Can I do it by configure the properties file ?

Thanks in advance

Moving this tread to "Other Open Source Projects", where log4j is discussed.

Aren't you just describing DailyRollingFileAppender?

Not really, the dailyrolling thing is just to add the time stamp to your preset log file name, it's not dynamic at all. I want wholely dynamic, like wholely wheat !!!
