Invited Talk: Distributed Tracing for MicroProfile Runtimes
summary
MicroProfile-OpenTracing adds automatic JAX-RS tracing and a @Traced option for CDI, propagates context across threads and service calls, and lets code add tags and baggage. Demo uses a front-end/back-end app instrumented with Jerger and Trontail, shows a 4 vs 10 span pattern caused by retries from fault‑tolerance, and surfaces a 67% probability tag added to a failing backend span. Roadmap covers better MicroProfile Rest Client integration and improved context propagation inside async/thread‑pool code.
