Which statement best describes the purpose of observability?

• A. To explain system behavior using data
• B. To eliminate bugs automatically
• C. To remove metrics
• D. To reduce logs to minimum

Answer: (A)

Observability is about understanding what a system is doing by looking at data from its inside, not just guessing from outside signs. The statement that best describes it is that observability explains system behavior using data. By collecting signals like metrics, logs, and traces, you can answer questions such as where a problem originated, why it happened, and how to prevent it in the future. It’s not about automatically fixing bugs—that would be automated remediation—and it isn’t about removing signals. Reducing or removing metrics or logs would actually reduce your ability to explain what’s going on. In practice, keep rich signals (metrics, logs, and traces) to form a coherent picture of how requests travel through the system and where issues lie.
