OpenTelemetry in Java: Tracing, Spans & Metrics Explained with Live Code Walkthrough

Are you ready to take your observability game to the next level? In this detailed video, José Cruz breaks down **OpenTelemetry**—the open-source, vendor-neutral standard for tracing, metrics, and logs—**with hands-on code examples in Java**. Whether you're new to distributed tracing or want to see how real-world telemetry is instrumented and exported, this video is for you!

We’ll cover everything you need to know to start capturing traces, spans, and metrics in your Java apps and view them directly in your console—**no backend required!**
