+If you have a Datadog Agent running on the same host as an OpenTelemetry Collector or DDOT Collector that uses a Prometheus receiver to scrape Collector health metrics, make sure the Agent's <a href="/integrations/openmetrics/">OpenMetrics integration</a> is either turned off or scraping a different endpoint than the Collector health metrics endpoint. Otherwise, both the Agent and Collector scrape the same endpoint, resulting in duplicate Collector health metrics.
