Full Stack Observability vs Monitoring: Key Differences

Traditional monitoring focuses on detecting known issues through predefined thresholds, but it lacks the depth to explain "how" or "why" failures occur in complex systems. In contrast, observability uses metrics, logs, and traces to provide end-to-end visibility, enabling automated root-cause analysis. This shift is essential for managing modern, cloud-native architectures where interconnected microservices make manual diagnosis nearly impossible.
