 Open WebUI supports **distributed tracing and metrics** export via the OpenTelemetry (OTel) protocol (OTLP). This enables integration with modern observability stacks such as **Grafana LGTM (Loki, Grafana, Tempo, Mimir)**, as well as **Jaeger**, **Tempo**, and **Prometheus** to monitor requests, database/Redis queries, response times, and more in real-time.
 
+For AI application observability backends that require custom OTLP headers, such as [Arize AX](https://arize.com/docs/ax/integrations/platforms/openwebui/openwebui-tracing), point Open WebUI at an OpenTelemetry Collector and let the collector forward traces with the required authentication headers.

 :::warning Additional Dependencies
 
 If you are running Open WebUI from source or via `pip` (outside of the official Docker images), OpenTelemetry dependencies **may not be installed by default**. You may need to install them manually:

+### Forward traces through a collector
+
+Some OTLP backends require custom headers that are better handled in an OpenTelemetry Collector. For example, Arize AX
+requires `space_id` and `api_key` headers on its OTLP exporter. Point Open WebUI at the collector, then configure the
+collector to add the backend-specific headers:
