log4j2 creates empty log file when configuration happens

[Tarun Sharma <ta...@oracle.com>]

Hi All,

 

I have recently upgraded to log4j2 and find that log4j creates empty log files for all my rolling file appenders when the java process starts up and initializes the log4j context.

So, even if some of my job threads are not running, they have empty log files created for the related appenders.

 

Is there a way to postpone the creation of log file to the time when first LogEvent is triggered?

 

Thanks and Regards,

Tarun

Yes, this is a new feature in 2.7, please see LOG4J2-1504
https://issues.apache.org/jira/browse/LOG4J2-1504 and "createOnDemand" in
https://logging.apache.org/log4j/2.x/manual/appenders.html#RollingFileAppender

Happy Hols!
Gary
