You may know I’m a big fan of #OpenTelemetry. I noticed massive differences in configuration and results across frameworks inside the same programming language.

I want to compare the different 0-code approaches on the #JVM, covering the most widespread.

Brilliant metaphor, super clear write-up.

Yeah, I kind of figured out the walks were early, but never did the math 😄

Wait... what... 4AM 😱
