-------------------------------------

             Summary: Date based file appender
                 Key: LOG4J2-1101
                 URL: https://issues.apache.org/jira/browse/LOG4J2-1101
             Project: Log4j 2
          Issue Type: New Feature
          Components: Appenders
            Reporter: Haavar Valeur


I'd like to reintroduce the option of logging to a file that has the current date in it. 

For example, when the app starts up, it will start logging to myapp-20150821.log. At midnight, it starts logging to a new file named myapp-20150822.log.

Log4j2's RollingFileAppender does not support this. In log4j2 the file appender will log to one file with a static file name, and then the content is moved over to another file. 

This used to be a feature in log4j 1.3, when using extras. I would configure it like this:
    <appender name="myapp" class="org.apache.log4j.rolling.RollingFileAppender">
        <rollingPolicy class="org.apache.log4j.rolling.TimeBasedRollingPolicy">
            <param name="FileNamePattern" value="myapp-%d{yyyyMMdd}.log"/>
        </rollingPolicy>
        ....
    </appender>
