Monitoring your LLMs with Langfuse

Observability refers to the ability to monitor and understand the internal state of an LLM application, including its inputs and outputs. watsonx Orchestrate provides observability through a native integration with an open-source project known as Langfuse. To enable IBM’s native observability framework, start the Orchestrate server with the --with-ibm-telemetry or -i flag, then go to https://localhost:8765 in your browser.
