Building a Foundation for Metrics in Elixir Applications

The talk focuses on creating a robust and deliberate metrics infrastructure in Elixir applications through tools like :telemetry, telemetry_metrics, and Phoenix LiveDashboard. It emphasizes the importance of thoughtful design decisions that can enhance the application's scalability, particularly at early stages. The speaker encourages developers to think about what and how to measure effectively within their applications while ensuring code maintainability by isolating metrics-related code into designated modules. This approach allows for a seamless transition to advanced tools like OpenTelemetry and Grafana without needing significant rewrites. Attendees will gain insights on how to start measuring metrics early, structure their code efficiently, and prepare for future scaling in observability tools.
