+## Tracing Services with OpenTelemetry Tracing and Jaeger
+
+> NOTE: limited support. Only LLM inference serving with TGI on Gaudi is enabled for this feature.
+
+OPEA microservice and TGI/TEI serving can easily be traced through Jaeger dashboards in conjunction with OpenTelemetry Tracing feature. Follow the [README](https://github.com/opea-project/GenAIComps/tree/main/comps/cores/telemetry#tracing) to trace additional functions if needed.
+
+Tracing data is exported to http://{EXTERNAL_IP}:4318/v1/traces via Jaeger.
+Users could also get the external IP via below command.
+
+```bash
+ip route get 8.8.8.8 | grep -oP 'src \K[^ ]+'
+```
+
+For TGI serving on Gaudi, users could see different services like opea, TEI and TGI.
