Create log4j logfiles per process

I'm using log4j2, and have my configuration in log4j2.xml (in classpath so it s automatically configured)

In this particular case, I want to create separate log files per process.

I have a framework with multiple packages and multiple classes. They all have statements like:

Logger logger = LogManager.getLogger(getClass());

Lets say I now have three processes A, B and C. How should I configure log4j to get three output files A.log, B.log and C.log and include the logging calls made in the framework classes?

I also want to be able to log individual packages/classes to other log appenders if I need to debug etc, so I would prefer to keep the getClass() argument mentioned above.

All ideas are welcome!

You can add the desired name at the time of creating the process, adding an argument to the Java virtual machine. e.g.:

java -Dcustom.log.name=/tmp/logs/A.log ... ...

So, you can use it:

<File name="Application" fileName="${custom.log.name}">

See more in Apache Log4j 2 User's Guide [PDF].

Give every process its own configuration file. Specify different paths in these configurations.

You can specify the full path of the configuration file with this system property: -Dlog4j.configurationFile=path/to/log4j2.xml
