I'm Tracing You!
summary
OpenTelemetry instruments applications end to end using a Java agent or library hooks, exports via OTLP to a collector and was shown pushing traces into Jaeger from Jetty/Quarkus apps. A demo builds a bookstore and a separate ISBN service; when the ISBN service is down the trace grows (4 → 7+ spans) and a Kafka fallback path persists the book, and when the service is up the trace crosses services normally. Context propagation works over HTTP headers and Kafka message headers and the setup runs in Docker Compose.
