I'm trying to have my own configuration for access logging with log4j2 logging framework in my web application that is using tomcat. While I see there is a Access log valve that can be used for logback, I didn't find any access log valve to override for log4j2 framework at all.

Tomcat version: 9

Any help is appreciated!!

Quoting directly from http://logging.apache.org/log4j/2.x/log4j-appserver/index.html. Note that most of the steps below are designed to keep the log4j overrides separate from the standard tomcat stuff.

Log4j may be used as the logging framework for Apache Tomcat. This support is implemented automatically by including the log4j-api, log4j-core, and log4j-appserver jars in the boot classpath. A file named log4j2-tomcat.xml, log4j2-tomcat.json, log4j2-tomcat.yaml, log4j2-tomcat.yml, or log4j2-tomcat.properties must also be placed in the boot classpath. This is most easily done by:

  1. Creating a set of directories in catalina home named log4j2/lib and log4j2/conf.
  2. Placing log4j2-api-2.13.0.jar, log4j2-core-2.13.0.jar, and log4j2-appserver-2.13.0.jar in the log4j2/lib directory.
  3. Creating a file named log4j2-tomcat.xml, log4j2-tomcat.json, log4j2-tomcat.yaml, log4j2-tomcat.yml, or log4j2-tomcat.properties in the log4j2/conf directory.
  4. Create or modify setenv.sh in the tomcat bin directory to include CLASSPATH=$CATALINA_HOME/log4j2/lib/*:$CATALINA_HOME/log4j2/conf
