Tracing Made Easy: A Beginner's Guide to Jaeger v2
Jaeger v1 reached end-of-life on December 31, 2025, and Jaeger v2 rebuilt the project on the OpenTelemetry Collector: no more agent, no more Jaeger clients, native OTLP everywhere. This hands-on guide explains distributed tracing, walks through what changed in v2, deploys Jaeger v2.20 and the HotROD demo with Docker, and shows how the same OTLP traces flow into OpenObserve unchanged.
