On the noisy NodeJS auto-instrumentation, it is indeed very noisy out of the box. Myself along with a bunch of other ppl finally got the project to allow you to select the instrumentations via configuration. Saves having to create your own tracer.ts/js file.
Here's the PR that got merged earlier in the year: https://github.com/open-telemetry/opentelemetry-js-contrib/p...
The env var config is `OTEL_NODE_ENABLED_INSTRUMENTATIONS`
Anyways, love Opentelemetry success stories. Been working hard on it at my current company and yielding fruits already :)
