Kafka Producer Metrics are only showing internal topics data

[srijita-mallick]

We have enabled Kafka Exporter metrics for our cluster.
When I query kafka topic metrics like kafka_topic_partitions, it shows the respective data for all topics.
But when I query kafka producer metrics like kafka_producer_producer_topic_metrics_record_send_rate, , it shows the data for only internal topics.
Below is the screenshot for same -

Do I have to add something more in the config for exporter or jmx?

Not sure I got you right. Strimzi and the Kafka Exporter or the JMX Prometheus agent in the Kafka operands monitor only them. They do not collect any metrics from your Kafka clients. So what exactly do you expect to see there? I guess what you see are the producers which are part of the operands and these are obviously mostly using internal topics only. If you want to monitor your own producers or consumers, you need to configure monitoring for them.

Thank you for the great explanation. I looked into it here and realised i need to also expose the Kafka Producer Client to get those metrics. Thanks!
