Support Tags/Labels

[jalogisch]

To make the handling of metrics easier it would be nice to have the option to use tags/lables in the metrics. This way it would be easier to work with Grafana and the data given by Graylog.

@jalogisch The metrics library used by Graylog doesn't support tags and not every metrics store (such as Graphite or statsd) supports tags either.

Quick update for anyone looking into this:

• dropwizard supports tags from version 4.1.8 onwards (changelog).
• Graylog 4.0.1 uses dropwizard 4.1.9 (pom.xml). So technically it should already be possible.

Nevertheless, the approach in https://github.com/Graylog2/graylog2-server/issues/9914 looks a lot more promissing.

• dropwizard supports tags from version 4.1.8 onwards (changelog).

That's only a special case for the Graphite Metrics Reporter.

Tags for metrics will be supported in Dropwizard Metrics 5.x, though. There's no scheduled date for Dropwizard Metrics 5.0.0 GA yet.
