I want to expose kafka and zookeeper metrics in prometheus. I do not want to use jmx_exporter because to integrate this I need to expose a port which has security vulnerabilities. Prometheus also has a third-party kafka_exporter. Is it possible to use Kafka_exporter without exposing jmx port? Or is there any other way I can get Kafka and zookeeper metrics?
AFAIK, there are multiple "kafka exporters" for prometheus
This one is written in Golang, and does not require JMX.
You could also set com.sun.management.jmxremote.registry.ssl=true to protect the JMX ports to clients with valid keys
