What is the proper way to check kafka cluster health?

Question

I'm developing an application that uses Kafka cluster behind an Elastic Load Balancer on AWS and I'm wondering, what is the best way to check health of instances in kafka cluster ?

Did anyone had a similar issue ?

We typically use a TCP call on either port 9092 or 9093, depending on whether your Kafka brokers are secure or not. I think you can potentially customise the port they listen on too, but those are the defaults.
