Any kind of intro/example project?

[skipsizemore]

I've been doing Go full-time for 8 years, and this is EASILY the most frustrating open-source project I have ever tried to use. All I want it to do is produce basic trace/span info and send it to an http endpoint. Trying to actually do this with the libraries available, their many conflicting module paths and versions, etc., is just maddening.

I can produce traces and dump them to stdout, but as soon as I try to send them anywhere, I am dead in the middle of dependency hell. It may be organized very cleverly for all I can tell, but without any docs that actually create a working app, it's hard to say. No example code I can find will compile.

Before I give up on this completely, is there a fully-working example project I can look at somewhere that does this extremely basic thing?

Maybe this is what you need, a working example.

I'd mention that that demo is out of date, since these two deps of it no longer exist:
go.opentelemetry.io/otel/sdk/metric/controller/basic
go.opentelemetry.io/otel/sdk/metric/processor/basic
see: https://github.com/open-telemetry/opentelemetry-go/tree/main/sdk/metric (no controller or processor subdirs anymore)

There is also this multi-apps demo: https://github.com/open-telemetry/opentelemetry-demo
