Beyond Green Lights: A Three-Layer Observability Stack for AI Agents

Traditional health checks fail to capture the true performance of AI agents—a technically successful response might still miss user needs. This three-layer observability approach (infrastructure metrics, AI traces, and quality evaluation) provides comprehensive visibility into agent reasoning and decision-making. For AI applications to be production-ready, you need to monitor not just system performance, but also the quality and correctness of agent outputs.
