Auto-Instrumenting Ruby Apps with OpenTelemetry

The tutorial provides a step-by-step guide to auto-instrumenting a basic Ruby "Hello World" application using OpenTelemetry. It details the process of setting up the Ruby OpenTelemetry client library, creating a Sinatra server, and configuring the application to generate and export trace data through the OpenTelemetry Collector. The tutorial emphasizes the simplicity of using OpenTelemetry's auto-instrumentation features, requiring minimal code changes to the application. Once the setup is complete, the application can send trace data to a distributed tracing tool, such as Logz.io or Jaeger, for visualization and analysis. The guide also explains how to configure the OpenTelemetry Collector to export trace data to a chosen backend and provides resources for further information on both automatic and manual instrumentation options.
