The utility of tracing is great, I've been using Azure Application Insights with NodeJS (and of course in .NET). This is relatively simple because it monkey patches itself everywhere if you go through the "classic" SDK route. Then adding your own data to logs is just a few simple functions trackTrace, trackException, trackEvent, etc.
However, if you want to figure out how it works you might be scared, it is not lightweight. I just spent a few days digging through the Azure Application Insights NodeJS code base which integrates with OpenTelemetry packages. It's an utter mess, a huge amount of abstractions. Adding it to the project brought 100 MB and around 40 extra packages.
