Instrument Your Java Applications with OpenTelemetry!
summary
Shows how to produce end-to-end OpenTelemetry traces from Java applications using three approaches: manual SDK instrumentation for full control, Spring Boot starter integration for quick framework hooks, or the JVM auto-instrumentation agent (≈100 built-in integrations) for the most complete traces. Covers exporting spans via OTLP to an OpenTelemetry Collector, W3C tracecontext/traceparent propagation for correlating spans across services, autoconfiguration through about 80 environment variables, and trade-offs (SDK = max control, starters = fast integration, agent = richest traces but possible JVM-agent conflicts and limited support for native images like Quarkus).
