Hello devs, Kafka has support for MX4j, that can be used to expose JMX beans over HTTP. https://github.com/apache/kafka/blob/trunk/core/src/main/scala/kafka/server/KafkaRaftServer.scala#L91 This feature is not documented and disabled by default. To enable it, you have to pass -Dkafka_mx4jenable=true and add the required JARs to the classpath. Activity on MX4J project has ceased and last release was 12/10/2006. We have an 8 years old post on Kafka users ML asking if there is any user, but no one replied. https://en.wikipedia.org/wiki/MX4J https://users.kafka.apache.narkive.com/4BMpuEMX/is-anyone-using-mx4j-loader My question is: should we deprecate and remove? I guess that would require a KIP. I have some time to work on this if there is agreement. Thanks Fede
