Observability is a measure of how well internal states of a system can be inferred from knowledge of its external outputs.
Observability in the context of software engineering refers to the ability to understand and analyze the internal state and behavior of a software system based on the data it generates.
Observability encompasses three main pillars: logs, metrics, and traces.
Observability allows software engineers to gain a holistic understanding of their systems, enabling them to detect and diagnose issues more effectively.
It helps in troubleshooting, performance optimization, capacity planning, and overall system reliability.
