i want to create log filename which includes uuid in name .

</Configuration>
but it is creating file "uuid:TIME-test.log".I have also try %uuid , %u but none of them is creating file with uuid .
This can be accomplished with a custom lookup. This answer gives example code for how to create a custom lookup in Log4j2 (it's only a few lines of code).

I cannot find the config error in this XML of Lo4jJ:

I expect to log all org.apache.axis messages with debug level. But I can see only debug from com.myapp.
I tried to set <Root level="debug"> and between billions of messages I can see axis logs... so I'm sure that package is logging.
I'm using Log4J 2.16.0 in a tomcat container Java 1.8
I have to switch Log4J configuration at runtime during tomcat webapp startup, I have tried this solution:
LoggerContext ctx = (LoggerContext) LogManager.getContext(false);
ctx.setConfigLocation(ResourceUtils.toURI(getClass().getResource("/mynewconfig.xml")));
ctx.start();
ctx.reconfigure();
It seems to work in a Windows environment, but this doesn't work for ubuntu/linux.
I added a System.out to check the existing appender just after this code, and in windows env I can find my new configured appenders, for linux I can see only the default startup one.
I have already checked file path permissions.

The problem was the Sandboxing filesystem of tomcat service in Ubuntu.
Take a look at https://www.freedesktop.org/software/systemd/man/systemd.exec.html
I hade to explicit set this configuration:
ReadWritePaths=/var/mypath
in /lib/systemd/system/tomcat.service file
I wanted to create log file in my maven project under project base directory.I am using log4j2 framework kept the log4j2.xml file under src/mian/resources folder. below is the file. please update what is wrong in it.

Here is what I see wrong in your configuration:
Maven builds run with the working directory set to the root directory of the project. Any files creates will be respective of that. In your configuration that means it would create the logs in a directory named appLogs. This is a poor practice in Maven builds. You should change it to target/applogs.
Your filePattern contains %d{dMM-dd-yy} but none of your triggering policies are time based. Without a time-based trigger I would expect that time to never changed while the application is running.
I am using Cassandra appender, console and file appenders in my application. I want to store only ERROR messages in Cassandra table Logs whereas store INFO messages to Console and file.
Below is the log4j2.xml file.

</Logger>
</Loggers>
In the last segment when I change the level to ${MINLEVEL} i.e INFO, then it works but ERROR is not working. Please help!
The issue is that additivity is set to false, this is preventing to duplicate the messages to the root and abc.xyz loggers. If you set additivity to false, it will be sent to both loggers.

I am trying to configure log4j2 to write logs in several files using Routing & RollingFile appenders, and so far everything works well. However, there is an unwanted side effect - it also logs into Linux syslog. Is there any way to disable logging into syslog? Here is my log4j2.xml:
