Control Center Stream Monitoring

Has anyone successfully run Control Center with Stream Monitoring using the docker images?

I’m running Docker image cp-control-center:3.0.1

I can navigate control center as expected, set up kafka connect settings, alerts, etc, but when producing and consuming messages Stream Monitoring shows no data.

I’ve pretty much followed the steps in the Control Center Quick Start Guide (http://docs.confluent.io/3.0.1/control-center/docs/quickstart.html), with the exception of starting the services (Skipping Step 1 - 7) , I have all the correct properties set that the guide states though.

The source and sink is working as expected, so in theory I should see data in the graph, but I don’t.

No errors or warnings in the logs for both Kafka Connect and Control Center, and after a day of debugging I’m out of ideas…

Can you include the properties set in /etc/kafka/secrets/ssl.properties?

In addition to setting security params like ssl.truststore.location at the top level for the consumer, you also need to pass them to the interceptor with properties like confluent.monitoring.interceptor.ssl.truststore.location.

Here’s an example: https://github.com/arrawatia/securing-kafka-blog/blob/master/manifests/default.pp#L435-L439

Awesome. I think it’s showing “Unknown cluster” b/c you’re using the 3.0.1 interceptors. If you change the Docker run commands to 3.1.1, you’ll get the new interceptors which understand Kafka cluster id.
