Daily Rolling File Appender Max backup index settings

[pushkar sawant]

Hi,



Is there a parameter setting available for configuring Max Backups stored on
the disk for DailyRollingFileAppender?



I have a jboss instance running and am trying to configure log4j.xml file to
limit number of backups stored on the disk. I went through some blogs and
found a parameter “MaxBackupIndex” to limit number of files. But this
setting is not working for me.



Also on wiki under the requested feature page (
http://wiki.apache.org/logging-log4j/Log4jRequestedFeatures), i see this
feature listed.


Has this feature been implemented? Is there any place where I can see why
this is failing.



I am using following log4j.xml file.



Thanks
