This tutorial covers how to integrate Goose with Langfuse to monitor your Goose requests and understand how the agent is performing.

What is Langfuse​

Langfuse is an open-source LLM engineering platform that enables teams to collaboratively monitor, evaluate, and debug their LLM applications.

Set up Langfuse​

Sign up for Langfuse Cloud here or self-host Langfuse Docker Compose to get your Langfuse API keys.

Configure Goose to Connect to Langfuse​

Set the environment variables so that Goose (written in Rust) can connect to the Langfuse server.

export LANGFUSE_INIT_PROJECT_PUBLIC_KEY=pk-lf-...
export LANGFUSE_INIT_PROJECT_SECRET_KEY=sk-lf-...
export LANGFUSE_URL=https://cloud.langfuse.com # EU data region 🇪🇺

# https://us.cloud.langfuse.com if you're using the US region 🇺🇸
# https://localhost:3000 if you're self-hosting

Run Goose with Langfuse Integration​

Now, you can run Goose and monitor your AI requests and actions through Langfuse.

With Goose running and the environment variables set, Langfuse will start capturing traces of your Goose activities.
