The [NGINX receiver](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/receiver/nginxreceiver) allows for collection of NGINX metrics and access to the [NGINX Overview](https://app.datadoghq.com/dash/integration/21/nginx---overview) dashboard. Configure the receiver according to the specifications of the latest version of the `nginxreceiver`.

For more information, see the OpenTelemetry project documentation for the [NGINX receiver](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/receiver/nginxreceiver).

## Setup{% #setup %}

To collect NGINX metrics with OpenTelemetry for use with Datadog:

1. Configure the [NGINX receiver](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/receiver/nginxreceiver) in your OpenTelemetry Collector configuration.
1. Ensure the OpenTelemetry Collector is [configured to export to Datadog](https://docs.datadoghq.com/opentelemetry/setup/collector_exporter.md).

See the [NGINX receiver documentation](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/receiver/nginxreceiver) for detailed configuration options and requirements.
