# Troubleshooting

> Resolve common tracing issues with OpenTelemetry SDK configuration and connectivity.

| Issue              | Solution                                                                        |
| ------------------ | ------------------------------------------------------------------------------- |
| No traces appear   | Configure OpenTelemetry SDK in application code; verify `tracing.enabled: true` |
| Connection errors  | Check collector is running; test with `ConsoleSpanExporter` first               |
| Import errors      | Install dependencies: `pip install nemoguardrails[tracing]`                     |
| Wrong service name | Set `Resource` with `service.name` in application code                          |
