kafka.yaml
zookeeper:
replicas: 3
jmxOptions: {}

Expected behavior
A clear and concise description of what you expected to happen.
it has to show jmx attributes wn we do ps -ef on zookeeper nodes.

Environment (please complete the following information):

• Strimzi version: [e.g. main, 0.22.1]
• Installation method: [e.g. YAML files, Helm chart, OperatorHub.io]
• Kubernetes cluster: [e.g. Kubernetes 1.20, OpenShift 4.7]
• Infrastructure: [e.g. Amazon EKS, Minikube]

YAML files and logs

Attach or copy paste the custom resources you used to deploy the Kafka cluster and the relevant YAMLs created by the Cluster Operator.
Attach or copy and paste also the relevant logs.

TBH, I'm not really sure what are you asking for. The docs describe how can you enable JMX. The resource snippet you shared is not properly formatted, so it is hard to say if you have it correct. But JMX is a socket where you connect with the client. There is not much to see with ps.

You should also double check if it is supported on your version - since you seem to use fairly old version of Strimzi and JMX support for ZooKeeper had been added only later - IIRC it was some time after the Kafka support.

WDYM with open issue? If it is not supported there then nobody is going to add it to such an old version and do a new release.

I figured there probably wouldn't be a patch release but thought I'd ask if there's a known workaround or anything. I found this discussion as well and looks like I had upvoted it back then. We plan on upgrading but it keeps getting put off because of the removal of the old CRDs and migrating to the new ones.

Hi @scholzj I tried to find some strimzi document on monitoring with Datadog, but didn't find any clue, can you please help to advise is monitoring with datadog recommended by Strimzi? and if yes, is there any document on this (integration for Strimzi Kafka and Datadog)

[scholzj]

I do not have any experience with Datadog, sorry. The preferred way from Strimzi point of view is Prometheus monitoring. There are multiple discussions about Datadog, so maybe you can read through them?

This should be resolved by #7535.
