What is openclaw-exporter-to-langfuse?

openclaw-exporter-to-langfuse is a plugin that collects observability data from OpenClaw, an AI gateway used for routing and managing LLM requests, and sends it to Langfuse, a platform for monitoring and evaluating AI applications. When you run AI agents that call language models and tools, it can be hard to understand what actually happened inside a given request: which agents ran, which tools were called, how many tokens were used, and what the prompts and responses looked like. This plugin hooks into OpenClaw and captures that information as structured spans, labeled records for each step such as agent invocations, LLM calls, tool executions, and session start and end events. Those spans follow the OpenTelemetry GenAI semantic conventions, a standard format for AI observability data, and are forwarded to Langfuse where you can view call chains, token usage, and prompt and response content. Separately and optionally, the plugin also supports routing infrastructure level metrics, gateway request rates, error rates, system logs, through a different pipeline to a data store and visualization tool of your choice. The README notes that on Alibaba Cloud, a managed offering called Agent-lens builds on top of this same infrastructure. Installation is handled by a shell script and managed by an AI agent that checks your OpenClaw version, looks up the compatible exporter version from a JSON compatibility matrix, and runs the appropriate installer. The plugin is written in TypeScript and licensed under MIT.
