Agent

The Datadog agent has a built-in StatsD server, exposed over a configurable port.

DogStatsD

https://docs.datadoghq.com/developers/dogstatsd/

DogStatsD is a metrics aggregation service bundled with the Datadog agent. DogStatsD implements the StatsD protocol and a few extensions (histogram metric type, service checks, events and tagging).

DogStatsD accepts custom metrics,events and service checks over UDP and periodically aggregates them and forwards them to Datadog.
