Chesnay Schepler commented on FLINK-24135:
------------------------------------------
??How about adding support for filtering on metric level???
That's a separate topic. It should be implemented in a generic fashion such
that it works for all reporters, just like the exclusion rules for variables.
It is furthermore relatively complex and needs a lot of thought put into it.
??Any reason why we have not extended support for tags in the main Flink repo's
StatsDReporter present here???
Because the StatsDReporter is supposed to support the StatsD protocol, not some
InfluxDB flavor of it. StatsD itself has no concept of tags, so the reporter
shouldn't either.
There are at least 4 different flavors of how tag support have been hacked into
the StatsD protocol (see https://github.com/statsd/statsd/issues/619), who
knows how many of them actually are there. We can't maintain such a mess.

> Key: FLINK-24135
> URL: https://issues.apache.org/jira/browse/FLINK-24135
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Metrics
> Reporter: Prakhar Mathur
> Priority: Major
> Labels: Metrics
>
> The current StatsDReporter in Flink does not support adding tags via Metric
> Group, which is currently being followed in Influx and Datadog reporter.
> Support for blacklisting tags and metrics will also be added as part of this
> in order to filter out metrics/tags which are not required by the user.
