LlamaIndex RAG tracing

Trace LlamaIndex RAG pipelines end-to-end. Capture retrieval, re-ranking, embeddings, and LLM synthesis as a single replayable trace.

Trace every LlamaIndex run

Full span traces

See the complete execution tree of every LlamaIndex run — nested spans, tool calls, and LLM requests on one timeline.

Cost & latency analytics

Track token usage, cost, and latency for every LlamaIndex call, broken down by model, prompt, or metadata.

Rich metadata & search

Tag, score, and search every request. Filter production traffic by content, model, status, or custom key-value pairs.

OpenTelemetry-native

LlamaIndex streams traces straight to PromptLayer's OTLP endpoint — no proxy in your request path, no SDK rewrite.

Debug in the playground

Open any LlamaIndex trace in the Playground to reproduce, tweak, and fix the exact prompt that failed.

Turn traces into evals

Promote real LlamaIndex runs into versioned datasets and run evaluation pipelines to catch regressions.

LLM Observability

Understand what your LlamaIndex app is doing

LlamaIndex powers retrieval-augmented apps. PromptLayer traces each query — retrieval, re-ranking, and synthesis — so you can debug RAG quality.

See the full picture

Every LlamaIndex run becomes a searchable, replayable trace — inputs, outputs, models, and timing.

Find the bottleneck

Pinpoint the slow span or expensive model call dragging down your LlamaIndex pipeline.

Catch failures fast

Surface errors, failed tool calls, and low-quality outputs before your users do.

Ship with confidence

Connect traces to evaluation pipelines so every change to your LlamaIndex app is tested.
