This would be a very welcome (actually needed) addition.
It was possible in Log4j 1.x, see
http://stackoverflow.com/questions/30059333/log4j2-rolling-appender-filename-sliding-according-to-pattern
Many people are requesting it
* see SO post above, with an ugly hack that unfortunately needs reflection on
the log4j2 API to get it done
* another SO post, of the above reporter:
http://stackoverflow.com/questions/27155363/log4j2-change-filename-dynamically-in-rollingfile-appender
* see also LOG4J2-1185
* also LOG4J2-239 and LOG4J2-1027 are the same underlying problem
* ...
As this was fairly easy possible in log4j 1.x, this is something we really miss
(without hack) in log4j2 for our required log file name structure...

> Key: LOG4J2-907
> URL: https://issues.apache.org/jira/browse/LOG4J2-907
> Project: Log4j 2
> Issue Type: Bug
> Components: Appenders
> Affects Versions: 2.1
> Environment: windows 7 enterprise
> Reporter: Clement Caylux
> Assignee: Ralph Goers
> Attachments: log4j2.xml
>
>
> I am using log4j2 and a rolling file appender, to roll file based on size and
> time. See my attached config file config file and the following snippet:
> {code:xml}
> <RollingFile name="RollingFile"
> filename="log/$${date:dd-MM-yyyy-HH-mm}/currentRoll.log"
> filePattern="log/%d{dd-MM-yyyy-HH-mm}/Roll-%i.log">
> <PatternLayout>
> <Pattern>%d{ISO8601}{GMT} %p %c{1.c} [%t] %m%n</Pattern>
> </PatternLayout>
> <Policies>
> <TimeBasedTriggeringPolicy interval="1"/>
> <SizeBasedTriggeringPolicy size="3KB"/>
> </Policies>
> </RollingFile>
> {code}
> My problem is that my current log (currentRoll.log) file is in the folder
> that was first created when the program started. I would need it to be in the
> last. So for example if I start running the program at 1pm on November 25th,
> 2014 , and at 3pm I want to look at the current logs they would not be in the
> 25-11-2014-15 folder but in the 25-11-2014-13 folder.
> My guess is that the date in the filename is not resolved dynamically. I have
> tried using monitorInterval to poll for auto reconfiguration but did not have
> any luck. I also tried using a '$$' in
> {code:xml}
> filename="log/$${date:dd-MM-yyyy-HH-mm}/currentRoll.log" .
> {code}
> but got the following error:
> {code}
> ERROR Unable to create file log/${date:dd-MM-yyyy-HH-mm}/currentRoll.log
> java.io.IOException: The filename, directory name, or volume label syntax is
> incorrect
> {code}
> Any suggestion?
