jmxOptions: {} not working

[Veljen]

Hi,

I have added the jmxOptions: {} and I am geeting empty server reply from 9999 port (localhost). jmxprometheusmetrics works fine with port 9404 but not this one. I am using latest operator version 0.39.

I am not seeing any relevant logs in broker and operator for this jmxoptions. Kindly help me
how to setup this and troubleshoot further.

[kafka@poc-strimizi-kafka-0 kafka]$ curl http:/poc-strimizi-kafka-0.poc-strimizi-kafka-brokers.strimzi-kafka-1.svc.cluster.local:9999
curl: (52) Empty reply from server

JMX is a protocol on its own. It is not HTTP. So you are not expected to get anything with HTTP client such as curl. You have to use some JMX client to connect to it.
