Instrument LangGraph agents with Datadog: a practical guide

Datadog's AI Agent Monitoring addresses the "black box" nature of AI agents by providing end-to-end visibility into workflows, tool executions, and performance metrics like latency and token consumption. Using a LangGraph agent as a case study, the article demonstrates how developers can instrument applications to trace failures, manage costs, and utilize automated LLM-as-a-judge evaluations to ensure output quality.
