Join an OpenTelemetry maintainer to learn how to instrument your Rails application with this growing open source project. We'll cover the basics of observability and the benefits you can receive from each of OpenTelemetry's three core signals: Traces, Metrics, and Logs. We'll talk about Active Support Notifications and how OpenTelemetry leverages them for automatic instrumentation, as well as the instrumentation strategies in other popular Rails-related libraries. Together, we'll configure the OpenTelemetry SDK in a minimal Rails application, add custom instrumentation to core methods within our application, and export the results to an observability backend.
