Rafał Chmielewski created KAFKA-12469: -----------------------------------------
Summary: The topic names in the metrics do not retain their format when extracting through JMX. Key: KAFKA-12469 URL: https://issues.apache.org/jira/browse/KAFKA-12469 Project: Kafka Issue Type: Bug Components: metrics Reporter: Rafał Chmielewski I have topic names that have a period in the name: product.order product.offering.price However, for the metrics issued by JMX by a program that is a consumer of Kafka messages, the dots are replaced with an underscore: kafka.consumer<type=consumer-fetch-manager-metrics, client-id=consumer-export-4, topic=product_offering_price, partition=1><>records-lead But for the producer, this problem doesn't occur: kafka.producer<type=producer-topic-metrics, client-id=bss.data.verification.pi_1, topic=product.offering.price><>record-send-total As a consumer I use Akka Alpakka. But I think it's using Apache library to connect to Kafka and report metrics via JMX. -- This message was sent by Atlassian Jira (v8.3.4#803005)
