OpenTelemetry<p>Our latest blog post explains how the End User SIG created a clear, low-effort, data-driven way for the <a href="https://fosstodon.org/tags/OpenTelemetry" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>OpenTelemetry</span></a> community to signal the work that matters most.</p><p>So the next time you’re browsing <a href="https://fosstodon.org/tags/OTel" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>OTel</span></a> issues, don’t just read and leave. When you find an issue that describes a problem you’re also facing or a feature you’d like to see implemented, give the issue description a 👍 reaction. That’s it! Like and subscribe. That’s the signal.</p><p><a href="https://opentelemetry.io/blog/2025/issue-participation/" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">opentelemetry.io/blog/2025/iss</span><span class="invisible">ue-participation/</span></a></p>

You may know I’m a big fan of #OpenTelemetry. I recently finished developing a master class for the YOW! conference at the end of the year. During development, I noticed massive differences in configuration and results across programming languages. Even worse, differences exist across frameworks inside the same programming language.

In this post, I want to compare the different zero-code OpenTelemetry approaches on the #JVM, covering the most widespread.
