-----------------------------------------------------------
[~apoorvmittal10] : The issue was just with the Yammer metric reporter since it
only uses the first four fields group, type, name and scope during reporting.
We replaced dot with underscore in scope to make it work better with Graphite
hierarchy. It would be useful to check if this is still an issue and if so,
there are better ways to handle it.

> Project: Kafka
> Issue Type: Bug
> Components: consumer, metrics
> Reporter: Rafał Chmielewski
> Assignee: Apoorv Mittal

> 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.
