This document discusses practical approaches to observability. It recommends starting with existing logs and structuring them consistently before scaling up logging. The key steps are: 1. Determine if observability is important to your team and methodology. 2. Choose a logging destination and library. Start simple by shipping existing logs. 3. Structure logs consistently with standard keys, labels to identify actions, and error handling. Prevent sensitive data and overflow. 4. Protect logs, sample high-volume logs, and optimize logging as services scale up. Share knowledge across teams.
