The adoption of Log4j overshadows all other java logging frameworks. With Log4j 2, Apache gave us a next-generation Asynchronous Logger based on the famous LMAX Disruptor library. Yes, we scale!
Therefore, it’s a pity that currently there is no official Logstash 2.x plugin for Log4j2. Unofficially? There is https://github.com/jurmous/logstash-log4j2, but unless you’re a Ruby expert, it would take considerable effort to compile and install it correctly. In this article we did that for you and present a small demo on docker-compose.
