> 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
>
> This creates a problem if I want to calculate the customer's lag in relation
> to the number of messages on Kafka.
>
> 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.
