Am using the following code to rollover logs each and every minute and it works perfectly.

log4j.appender.AllFlows=org.apache.log4j.rolling.RollingFileAppender
log4j.appender.AllFlows.rollingPolicy=org.apache.log4j.rolling.TimeBasedRollingPolicy
log4j.appender.AllFlows.rollingPolicy.File=E:/Logs/AllFlows.log 
log4j.appender.AllFlows.rollingPolicy.FileNamePattern=E:/Logs/AllFlows.log.%d{yyyy-MM-dd-HH-mm}
log4j.appender.AllFlows.MaxBackupIndex=10
log4j.appender.AllFlows.layout=org.apache.log4j.PatternLayout
log4j.appender.AllFlows.layout.ConversionPattern=%d %-5p %x - %m%n

However i just want to know , are they any alternatives for MaxbackupIndex as this is not working as expected when i use TimebasedRollingPolicy?

Am using log41.2.17 and apache log4j extras

Unfortunately, this is not possible using the standard API of log4j or even with the Extras.

However, you can use the class org.apache.log4j.DailyMaxRollingFileAppender 1, e.g.:

log4j.appender.AllFlows=org.apache.log4j.DailyMaxRollingFileAppender
log4j.appender.AllFlows.File=E:/Logs/AllFlows.log 
log4j.appender.AllFlows.MaxBackupIndex=10
log4j.appender.AllFlows.DatePattern='.'yyyy-MM-dd-HH-mm
log4j.appender.AllFlows.layout=org.apache.log4j.PatternLayout  
log4j.appender.AllFlows.layout.ConversionPattern=%d %-5p %x - %m%n

Notes

  1. See the code of this class in Custom DailyRollingFileAppender with MaxBackupIndex.
