LiveKit Agents Tracing Integration

Trace real-time voice AI agents and multimodal conversations built with LiveKit Agents via OpenTelemetry and Langfuse

We’ve added a new LiveKit Agents integration guide that shows how to trace real-time voice AI applications built with LiveKit Agents using Langfuse.

LiveKit Agents is an open-source Python and Node.js framework for building production-grade multimodal and voice AI agents. The integration leverages LiveKit’s built-in OpenTelemetry support to send comprehensive telemetry data to Langfuse.

The integration captures traces for key agent activities including:

Session management
Agent turns and conversations
LLM node executions
Function tool calls
Text-to-speech processing
End-of-turn detection
Performance metrics
