> Allow configuration of MetricsReporter subclasses
> -------------------------------------------------
>                 Key: KAFKA-3711
>                 URL: https://issues.apache.org/jira/browse/KAFKA-3711
>             Project: Kafka
>          Issue Type: Improvement
>          Components: clients, streams
>            Reporter: Jeff Klukas
>            Assignee: Guozhang Wang
>            Priority: Minor
>             Fix For:
> The current interface for attaching metrics reporters to clients allows only defining
a list of class names, but provides no means for configuring those reporters.
> There is at least one existing project (https://github.com/apakulov/kafka-graphite) that
solves this problem by passing additional properties into the client, which then get passed
on to the reporter. This seems to work quite well, but it generates warnings like {{The configuration
kafka.graphite.metrics.prefix = foo was supplied but isn't a known config.}}
> Should passing arbitrary additional parameters like this be officially supported as the
way to configure metrics reporters? Should these warnings about unrecognized parameters be
> Perhaps there should be some mechanism for registering additional configuration parameters
for clients to expect?
