Github user hadronzoo commented on the issue: https://github.com/apache/flink/pull/3833 @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.
