Open-source observability for your LLM application

🎉 New:Our semantic conventions are now part of OpenTelemetry! Join thediscussion and help us shape the future of LLM observability.

Looking for the JS/TS version? Check outOpenLLMetry-JS.

OpenLLMetry is a set of extensions built on top ofOpenTelemetry that gives you complete observability over your LLM application. Because it uses OpenTelemetry under the hood,it can be connected to your existing observability solutions - Datadog, Honeycomb, and others.

It's built and maintained by Traceloop under the Apache 2.0 license.

The repo contains standard OpenTelemetry instrumentations for LLM providers and Vector DBs, as well as a Traceloop SDK that makes it easy to get started with OpenLLMetry, while still outputting standard OpenTelemetry data that can be connected to your observability stack.If you already have OpenTelemetry instrumented, you can just add any of our instrumentations directly.

The easiest way to get started is to use our SDK.For a complete guide, go to ourdocs.

Install the SDK:

pip install traceloop-sdk

Then, to start instrumenting your code, just add this line to your code:

fromtraceloop.sdkimportTraceloopTraceloop.init()

That's it. You're now tracing your code with OpenLLMetry!If you're running this locally, you may want to disable batch sending, so you can see the traces immediately:

Traceloop.init(disable_batch=True)

OpenLLMetry can instrument everything thatOpenTelemetry already instruments - so things like your DB, API calls, and more. On top of that, we built a set of custom extensions that instrument things like your calls to OpenAI or Anthropic, or your Vector DB like Chroma, Pinecone, Qdrant or Weaviate.

The SDK provided with OpenLLMetry (not the instrumentations) contains a telemetry feature that collectsanonymous usage information.

You can opt out of telemetry by setting theTRACELOOP_TELEMETRY environment variable toFALSE, or passingtelemetry_enabled=False to theTraceloop.init() function.

• The primary purpose is to detect exceptions within instrumentations. Since LLM providers frequently update their APIs, this helps us quickly identify and fix any breaking changes.
• We only collect anonymous data, with no personally identifiable information. You can view exactly what data we collect in ourPrivacy documentation.
• Telemetry is only collected in the SDK. If you use the instrumentations directly without the SDK, no telemetry is collected.

Whether big or small, we love contributions ❤️ Check out our guide to see how toget started.
