What is Observability?
Observability is the ability to understand what is happening inside a running API by examining the data it produces, such as logs, metrics, and traces. A highly observable API lets you answer questions like "why did this request fail", "where is the latency coming from", and "is this service degrading" without needing to reproduce the problem locally.
