```go

```go
tracer := tp.Tracer("test-tracer")
ctx, span := tracer.Start(context.Background(), "CollectorExporter-Example")
defer span.End()
defer span.End()
```
The traces should now be visible from the Jaeger UI (if you have it installed), or thorough the jaeger-query service, under the name `test-service`.
