# Kamon OpenTelemetry Trace Exporter
Provides a OpenTelemetry (OTLP) exporter for Kamon spans
The reporter relies on the [opentelemetry-proto](https://github.com/open-telemetry/opentelemetry-proto) library for the gRPC communication with an OpenTelemetry (OTLP) service.
## Local testing
To see the results of the exporter one can runt it against an instance of the [OpenTelemetry Collector](https://opentelemetry.io/docs/collector/).
The collector can be started in a container, configured to receive gRPC calls with trace data.
Run the script
```
./otel-collector.sh
```
If will start the OTEL Collector, configured for port `55690` and only to log all received traces.
The run the test application which generates one single trace with three spans (incoming/request and two client spans)
```
sbt app/run
```
This would log something like
```
[main] INFO org.dmonix.kamon.otel.OpenTelemetryTraceReporter - Creating OpenTelemetry Trace Reporter
[main] INFO org.dmonix.kamon.otel.OpenTelemetryTraceReporter - Configured endpoint for OTLP trace reporting [http://localhost:55690]
```
and in the collector the received spans are logged
```
