About New Relic Prometheus Agent
New Relic created the Prometheus Agent in order to simplify the experience of configuring features like discovery, filtering, metrics decoration, and sharding.
It generates a configuration file that is used to run a Prometheus Server in Agent mode to later send the metrics to the New Relic Remote Write Endpoint.
