Hi Naz, Volkan has contributed a fantastic json template layout that I expect will do what you want, however it has not been released yet. https://github.com/apache/logging-log4j2/pull/335
This discussion from the mailing list provides several options which may be relevant to your use case: https://lists.apache.org/thread.html/r538bb480c6d92813224b6a207e34210cccebc01e8d1781943d0ce32d%40%3Clog4j-user.logging.apache.org%3E > But my custom json layout doesn't write into a file. Do I have to write a > file appender for that? Layout implementations can be configured with any appender, the existing file based appenders work with custom layouts. The layout is responsible for converting a LogEvent into a format (e.g. bytes) that can be written to an appender (file, socket, standard out, etc) without being aware of the appenders implementation details.
