Gian Luca commented on KAFKA-14081:
-----------------------------------
I made a pull request to add a few lines of Javadoc, but some build checks are
failing. I can only think of a glitch, is there a way I can run them again?
PR: [https://github.com/apache/kafka/pull/12546]
> Cannot get my MetricsReporter implementation to receive meaningful metrics
> --------------------------------------------------------------------------
>
> Key: KAFKA-14081
> URL: https://issues.apache.org/jira/browse/KAFKA-14081
> Project: Kafka
> Issue Type: Bug
> Components: clients
> Affects Versions: 3.3.0
> Reporter: Gian Luca
> Priority: Minor
>
> I want to extract metrics from KafkaProducer to export them to our company
> monitoring solution. At first I went for implementing {{MetricsReporter}} and
> registering my implementation through the "metric.reporters" config property.
> The class is correctly registered as it receives metric updates through
> {{metricChange()}} while KafkaProducer is being used. The problem is that all
> the metric values are stuck at zero (NaN in older versions of Kafka), even
> the most trivial (e.g. 'record-send-total').
> If instead of using a report I simply poll the {{metrics()}} method of the
> KafkaProducer, then I see meaningful values: counters increasing over time,
> etc.
