# PhoenixOpentelemetryExample
This is an example repository that is implemented with Phoenix using OpenTelemetry to send traces to DataDog.
## Try
At first, export these environment to send metadata information to DataDog.
```
export DD_API_KEY=
export OTEL_SERVICE_NAME=phoenix_opentelemetry_example
export OTEL_RESOURCE_ATTRIBUTES=deployment.environment=local,host.name=local
```
Then, start OpenTelemetryCollector.
```
$ docker-compose run --rm --service-ports otel-collector
```
And start Phoenix server.
```
$ mix phx.server

```
When you access `http://localhost:4000`, Phoenix recieves the request. And the trace will be sent to DataDog through OpenTelemetry container.
