Otis Gospodnetic commented on KAFKA-2569:
-----------------------------------------
bq. This would allow monitoring of Kafka itself without requiring people to set
up their own JMX-to-monitoring-system pipelines.
But wouldn't that then require people to set up their own "Kafka topic to
monitoring system" pipelines, which relatively few people and monitoring tools
have?

> Kafka is often used to hold and transport monitoring data.
> In order to monitor Kafka itself, Kafka currently exposes many metrics via
> JMX, which require using a tool to pull the JMX metrics, and then write them
> to the monitoring system.
> It would be convenient if Kafka could simply send its metrics to a Kafka
> topic. This would make most sense if the Kafka topic was in a different Kafka
> cluster, but could still be useful even if it was sent to a topic in the same
> Kafka cluster.
> Of course, if sent to the same cluster, it would not be accessible if the
> cluster itself was down.
> This would allow monitoring of Kafka itself without requiring people to set
> up their own JMX-to-monitoring-system pipelines.
