Rafał Chmielewski resolved KAFKA-12470. --------------------------------------- Resolution: Duplicate > The topic names in the metrics do not retain their format when extracting > through JMX. > -------------------------------------------------------------------------------------- > > Key: KAFKA-12470 > URL: https://issues.apache.org/jira/browse/KAFKA-12470 > Project: Kafka > Issue Type: Bug > Components: metrics > Reporter: Rafał Chmielewski > Priority: Major > > 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)
