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.

API Key

https://docs.datadoghq.com/account_management/api-app-keys/#api-keys

An API key is required by the Datadog Agent to submit metrics and events to Datadog. The API keys are also used by other third-party clients, such as, for example, the Pulumi Datadog resource provider, which provisions infrastructure on the Datadog backend.
