Traditional observability was built for deterministic software, monitoring what happened through metrics, logs, and traces. Agentic systems introduce a new failure mode: invisible drift, where reasoning degrades without operational signals. Dashboard stays green, uptime remains perfect, but trust has already slipped away.

This module introduces the fundamental shift from monitoring actions to understanding decisions. You'll learn why security defines who may act, but observability proves what actually happened, and why both are required for autonomous systems to earn trust. Through real-world case studies from healthcare compliance failures and financial risk advisory systems, you'll identify the four core dimensions of agentic observability and map your own system's blind spots.
