Jaeger Project Intro - Juraci Kröhling
summary
Demo runs three microservices (two Spring Boot jars) with auto-instrumentation via OpenTracing contrib for Spring added as Maven deps; Jaeger runs in Docker on port 16686 and the app-side Jaeger client sends spans via UDP client -> agent -> collector -> storage pipeline. UI shows one trace per request (cold start 390 ms then ~15 ms and 13 ms), spans include HTTP URL, host, tags and logs. One downstream service is intentionally uninstrumented so it’s invisible in the trace.
