Tzu-Li (Gordon) Tai commented on FLINK-7624:
--------------------------------------------
I think changing an existing metric name would in a sense be breaking "public
API". We could think of adding a new set of metrics for this that separates the
metrics per-topic, while still keeping the original metrics.
> Add kafka-topic for "KafkaProducer" metrics

> Key: FLINK-7624
> URL: https://issues.apache.org/jira/browse/FLINK-7624
> Project: Flink
> Issue Type: Bug
> Components: Metrics
> Reporter: Hai Zhou
> Assignee: Hai Zhou
> Fix For: 1.4.0
>
>
> Currently, metric in "KafkaProducer" MetricGroup, Such as:
> {code:java}
> localhost.taskmanager.dc4092a96ea4e54ecdbd13b9a5c209b2.Flink Streaming
> Job.Sink--MTKafkaProducer08.0.KafkaProducer.record-queue-time-avg
> {code}
> The metric name in the "KafkaProducer" group does not have a kafka-topic name
> part, if the job writes data to two different kafka sinks, these metrics
> will not distinguish.
> I wish that modify the above metric name as follows:
> {code:java}
> localhost.taskmanager.dc4092a96ea4e54ecdbd13b9a5c209b2.Flink Streaming
> Job.Sink--MTKafkaProducer08.0.KafkaProducer.<kafka
> topic>.record-queue-time-avg
> {code}
> Best,
