As it stands a metric can have at most 10 labels, and there aren't any
current plans to extend this set; according to the docs that's still ok. If
this does indeed become a problem we can add a switch to rely on the scope
formats instead, giving the user control as to how many labels there are.

> URL: https://issues.apache.org/jira/browse/FLINK-6221
> Project: Flink
> Issue Type: Improvement
> Components: Metrics
> Affects Versions: 1.2.0
> Reporter: Joshua Griffith
> Assignee: Maximilian Bode
> Priority: Minor
>
> [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.
