Introducción

Add OpenTelemetry traces to Node.js LLM apps with OpenLLMetry JS so you can debug latency, tool calls, and RAG steps. Works with a standard OTEL backend.

  • Best for: Node.js teams who want trace-level visibility into LLM calls and tool/RAG pipelines
  • Works with: Node.js, OpenTelemetry collectors, tracing backends (Jaeger, OTEL-compatible vendors)
  • Setup time: 14 minutes

Quantitative Notes

  • Setup time ~14 minutes (npm install + OTEL exporter config)
  • GitHub stars + forks (verified): see Source & Thanks
  • Aim for <1% overhead by sampling traces (e.g., 1/100 requests in prod)

Practical Notes

Good traces answer: where time went and what failed. Model calls, retrieval, tool execution, and output parsing should each be a span. Record request IDs, model name, and high-level outcome, but avoid logging raw prompts—store hashes or redacted summaries to keep privacy and cost under control.

Safety note: Treat traces as sensitive: redact prompts, mask PII, and set retention limits.

FAQ

Q: Is this vendor-specific? A: No. It uses OpenTelemetry so you can export to any OTEL-compatible backend.

Q: What should I trace first? A: Start with LLM latency + token usage (if available), then add spans for retrieval and tools.

Q: How do I control cost? A: Use sampling, redact sensitive attributes, and keep span attributes small.
