Log4J Log Rotation

Question

We have a business requirement to keep last 7 days log Can we use log4j to delete old 7 days log.

We are using

log4j.appender.stdout=org.apache.log4j.RollingFileAppender

Please let me know.

Answer 1

You could use an enhanced version of the DailyRollingFileAppender Use MaxBackupIndex in DailyRollingFileAppender -log4j

Otherwise you could create a cron job that just deletes the logs over a certain age:

find /your/log/dir -name "*.log" -ctime +7 -exec rm {} \;
