When we run the Kafka Exporter, we are running as

kafka_exporter --kafka.server=kafka_cluster1:9092 --kafka.server=another_kafka_cluster:9092

When we try to pull two kafka cluster metrics using one process, it is only returning one and ignoring another. My understanding is one kafka exporter can only scrape metrics from one cluster and we can-not use one kafka exporter service to scrape multiple kafka clusters.

Any expert input on this! or can you please let me know if my understanding is correct?

I think multiple --kafka.server flags are to let you select multiple bootstrap nodes in the *same* kafka cluster. This allows it to be resilient at startup in the case that one node is down.
