    @mbode thanks for working on this!
    
    One thing that I've found useful when exporting Flink's statsd metrics to Prometheus is to make several of the metric fields tags: like `job_name`, `task_name`, `operator_name`, etc. This [statsd-exporter mapping](https://gist.github.com/hadronzoo/621b6a6dce7e2596d5643ce8d1e954ea) has tags that have worked well for me. I'm not tagging host names or IP addresses because Prometheus's Kubernetes support does that already, but that could be useful for people running standalone clusters.

> [Prometheus|https://prometheus.io/] is becoming popular for metrics and alerting. It's possible to use [statsd-exporter|https://github.com/prometheus/statsd_exporter] to load Flink metrics into Prometheus but it would be far easier if Flink supported Promethus as a metrics reporter. A [dropwizard client|https://github.com/prometheus/client_java/tree/master/simpleclient_dropwizard] exists that could be integrated into the existing metrics system.
