Instrument LLM apps with OpenTelemetry — semantic conventions for gen-ai, distributed tracing, and vendor-neutral observability.
Five passes over the same idea, each from a different angle. Do them in order, or jump to whichever you need.
OpenTelemetry is becoming the standard for LLM observability. The gen-ai semantic conventions define spans for LLM calls, embedding generation, and retrieval. Benefits: vendor-neutral instrumentation, distributed tracing across RAG pipelines, and export to any backend (Jaeger, Grafana, Datadog).
