Description

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:

 <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>

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

filename="log/$${date:dd-MM-yyyy-HH-mm}/currentRoll.log" .

but got the following error:

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

Any suggestion?
