In Cloud Native Observability, what are Logs primarily used for?

• A. To output messages from programs, applications, and processes
• B. To output performance metrics
• C. To route requests
• D. To store configuration

Answer: (A)

Logs are the records produced by software that capture messages about what happened inside programs, applications, and processes. They include timestamps, severity levels, and contextual data, making them a detailed history of events, errors, and state changes. This detailed narrative is invaluable for debugging and incident investigation, helping you answer questions like what went wrong and why. They differ from metrics, which are numeric summaries used for monitoring that tell you health and performance trends (like latency or error rate) over time, and from traces, which show how a single request flows through multiple services. Logs also aren’t meant to store configuration data—that role belongs to configuration management components. In short, logs provide the actual events and messages emitted by the system, making them the primary source for diagnosing issues and understanding the exact what-and-when of runtime behavior.
