Is your feature request related to a problem? Please describe.

I want to export metrics via StatsD, a common protocol used for many backends including Graphite.

Describe the solution you'd like

StatsD exporter.

Describe alternatives you've considered

Additional context

open-telemetry/opentelemetry-specification#374 should be of interest:

The reason we can't do this is that statsd (and dogstatsd) do not have a formal specification.

We will not pursue a statsd implementation until there is a specification to follow. Let's revisit this discussion when there is a specification to follow.

It's still true that there's no statsd spec, although at least one document in the OTel org describes it now:
https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/master/receiver/statsdreceiver/README.md

Most systems that support statsd also support other formats, which is part of the reason that we haven't included statsd in the OTel specification.

That said, it's a very useful protocol that can be implemented with few dependencies and people like it for that reason. I am supportive of including statsd exporters, e.g., https://github.com/open-telemetry/opentelemetry-go-contrib/tree/master/exporters/metric/dogstatsd

I think we should add it to the contrib repo. It can be upgraded to main repo when the spec includes it.

And FYI, there is already a mature Node.js StatsD client (node-statsd).

FWIW https://github.com/brightcove/hot-shots is also a good one

The metrics SDK is under active development. We will revisit this after #2574 is settled.
