Ask Miss O11y: Is There a Beginner’s Guide On How to Add Observability to Your Applications?

Observability in microservices can be effectively initiated by focusing on tracing rather than metrics, with OpenTelemetry recommended as a starting point for implementing SDKs for tracing in applications. By using tools like Jaeger to manage trace data, developers can gain detailed insights into user experiences, which are often lost when solely relying on metrics that focus more on infrastructure aspects like CPU usage. As understanding deepens, additional tracing information can be added to increase visibility, and various advanced observability techniques, such as service level objectives and service maps, can be explored based on the application's scale. For those seeking to expand their knowledge, literature by experts like Charity Majors, George Miranda, and Liz from Honeycomb is suggested, offering insights beyond beginner guides.
