May I work on this?
Does this require a KIP?)
> MetricsReporter does not get auto-generated client.id
> -----------------------------------------------------
>
> Key: KAFKA-6123
> URL: https://issues.apache.org/jira/browse/KAFKA-6123
> Project: Kafka
> Issue Type: Improvement
> Components: clients, metrics
> Affects Versions: 0.11.0.0
> Reporter: Kevin Lu
> Priority: Minor
> Labels: clients, metrics, newbie++
>
> When a {{MetricsReporter}} is configured for a client, it will receive the
> user-specified configurations via {{Configurable.configure(Map<String, ?>
> configs)}}. Likewise, {{ProducerInterceptor}} and {{ConsumerInterceptor}}
> receive user-specified configurations in their configure methods.
> The difference is when a user does not specify the {{client.id}} field, Kafka
> will auto-generate client ids (producer-1, producer-2, consumer-1,
> consumer-2, etc). This auto-generated {{client.id}} will be passed into the
> interceptors' configure method, but it is not passed to the
> {{MetricsReporter}} configure method.
> This makes it harder to directly map {{MetricsReporter}} with the
> interceptors for the client when users do not specify the {{client.id}}
> field. The {{client.id}} can be determined from identifying a metric with the
> {{client.id}} tag, but this is hacky and requires traversal.
> It would be useful to have auto-generated {{client.id}} field also passed to
> the {{MetricsReporter}}.
