Hey Shekar, You can also use the RollingFileAppender. You can both specify the maximum number of files and the maximum number of files you want to keep.

I did a quick search online to see whether there is any configuration for DailyRollingFileAppender and couldn't find any. The closest thing is this one: http://wiki.apache.org/logging-log4j/DailyRollingFileAppender.

You can change the log4j.xml to config as you want. Usually, daily base is good enough.
