AgentOps in watsonx Orchestrate: Observability for Agents with Langfuse and IBM Telemetry

Imagine a smart AI agent that answers questions, automates workflows, and makes decisions. But, do you really know what happens inside its mind? Is it choosing the actions correctly, responding to queries quickly, or wasting system resources?

This is where AgentOps and LLM observability help. Similar to DevOps for software engineering, AgentOps and LLM observability platforms such as Langfuse and IBM Telemetry provide complete visibility into your AI applications. They help with:

• Tracking prompts, responses, and metadata for every model call
• Measuring latency, costs, and token usage over time
• Capturing success and failure rates with root causes
• Running A/B tests for prompts or model settings
• Displaying real-time dashboards to optimize performance and ensure compliance

In this tutorial, learn how to choose and use the right LLM observability in watsonx Orchestrate Agent Development Kit (ADK) to build production-ready AI agent workflows. This tutorial also helps you to establish end-to-end visibility, streamline debugging, and optimize agentic workflows for production environments.
