My demo of OpenTelemetry Tracing features two Spring Boot components. One uses the Java agent, and I noticed a different behavior when I recently upgraded it from v1.x In the other one, I'm using Micrometer Tracing because I compile to GraalVM native, and it can't process Java agents.

In my tracing demo , I use Jaeger instead of the Collector. The OpenTelemetry Collector sits at the center of the OpenTelemetry architecture but is unrelated to the W3C Trace Context. Yet, it's ubiquitous, as in every OpenTelemetry-related post. I wanted to explore it further. In this post, I explore the different aspects of the Collector:

One of the components of my OpenTelemetry demo is a Rust application built with the Axum web framework. In its description, axum mentions: axum doesn't have its own middleware system but instead uses tower::Service. This means axum gets timeouts, tracing, compression, authorization, and more, for free.
