chetanmeh commented on issue #4481: Track Kafka client side metrics via Kamon URL: https://github.com/apache/incubator-openwhisk/pull/4481#issuecomment-492911141 @style95 Agreed that JMX exporters can be used. However I find them tricky to setup and each monitoring system has its own way of exporting ([Datadog][1], [Prometheus][2] etc). In most cases it involves running another agent which needs a custom Docker build and for Prometheus results in having 2 http servers running exposing the metrics. As OpenWhisk uses Kamon which abstract away all such integrations I was looking for a way to route such metrics to Kamon and then sent to various monitoring systems in a uniform way. Further note that proposed `KamonMetricsReporter` is optional (disabled by default) and would introduce a minimal overhead in terms of metrics collected and reported [1]: https://docs.datadoghq.com/integrations/java/ [2]: https://github.com/prometheus/jmx_exporter
