tl;dr:"We define observability as a continuous process of humans asking questions about production, and getting answers." Breaking that down: (1) Continuous process: Observability means folks observe as frequently as possible. (2) Questions about production: We wanted our definition to be wide, generic, and representative of the broad scope of workflows we cater for. (3) Answers: No tool will give you answers, only offer leads to find real answers. You have to use your own mental models of the systems you run.
