It’s a bit deeper than that. The SDKs that library authors implement need to be extemely minimal. The collection libraries that vendors implement based on imo should also be minimal.

OTLP imo doesn’t even need to be part of the spec.

But minimal would also mean focusing on solving fewer problems as a whole. Eg OpenTracing plus OpenMetrics plus OpenLogs. I only need one of those things.

Well, on OTLP they seem to agree with you: https://opentelemetry.io/blog/2023/otel-arrow/

that just sounds like a branding problem though...

OTLP has been quite useful especially in metrics to get a format that doesn't really have any sacrifices/limitations compared to all the other protocols.

It is! But to prove your point, OTLP is actually just the transport protocol (Open Telemetry Transport Protocol). Its one of _so many things_ its trying to address. All of those things might be probems, but not everyone has those same problems (vendors, customers, and lib authors), and bundling them all into one umbrella just screams for me.

I actually have no need for a standard metrics implementation, just as an example. I never have, and I'd argue Sentry (as a tech company) never has. We built our own abstraction and/or used a library. That doesnt mean others don't, and it doesnt mean it shouldnt be something people solve, but bundling "all telemetry problems" into one giant design committee is a fundamental misstep imo.

I read all your comments in this thread and I am still confused as to what your actual problem is.

Would it help you if all language-specific OTel libraries had 3 parts: metrics, log, traces? Namely you want finer-grained opt-in approach for the programmer-users? Or is it something else you have a problem with?

Saying OTel is a failure of a design committee process is to me blowing hot air; you are telling us your conclusion and I personally care exactly zero about your conclusion. I want to see your process of arriving at the said conclusion. And so far neither the OP nor your comments here gave me almost any enlightenment in this regard.

Are you open to clarifying further?

I want one fundamental thing: the ability to ask library authors to implement span annotations in their projects. Today that ask comes with way too much baggage. The SDKs are often extremely complex ("bloated", other's words, not mine), and on top of that, most of these library authors don't use or care about the standard. The latter can be fixed w/ funding, the former is what I'm concerned complaining about.

What I mean by that in practical terms is very easily articulated when we look at something like bundling of logs. We've had standardzed formats, adapters, and transports for logging for decades. Could they be better? Sure. Aint no future though where someone builds an SDK and no one ever again innovates or has an alternative path to achieving it. The same is true for everything, logs are just an an easy thing to pick on.

Take that a little further - why do I need a logging SDK bundled with a tracing SDK? I mean that very literally - why _must_ they be bundled? What do we get out of it?

You can argue that "just dont use the other parts", but thats an academic argument at best. In practice that just means you've got an overloaded SDK with a bunch of bias associated with it - in this case (in my opinion) a bunch of companies who don't really innovative pushing legacy telemetry concepts on the masses. That might not sound like a problem, but a developer can barely make sense of the docs, and even at the most basic level, I shouldnt need to make an argument about software branching complexity to other software engineers. They're simply trying to do too many things.

What that ultimately boils down to me though is: what problem is it solving? Tracing is a serious value add to _most_ stacks these days that requires immense amount of coordination to solve. It's not maintainable (easily) through patching other's code, which goes back to why I personally agree w/ OpenTracing's original pitch. However, why, with that goal unsolved, did we attach a bunch of other loosely-but-mostly unrelated problems to the spec? At the very least, problems that dont apply universally to the same audience. Why did we need a spec that bundled all of these problems, and continues to try to bundle more?

So I go back to the core problem: we want universal span annotations implemented across the ecosystem. I dont see what OTel is doing as the most effective way to achieve that goal, and I dont see the other goals they're trying to solve for as ones that are actually that important to most developers (and quite frankly, I could not tell you what many of those goals even are).

A lot of the development of OTel looks like two things:

1) Startups wanting easy access to telemetry, often without any product differention, thus, stakeholders who I dont find totally relevant to the conversation. I'm sure that comes off as me being an asshole, but its how I feel.

2) Big vendors trying to push consolidation on the customers, all competing with the exact same products (think Datadog and all its copycats, again often with no product innovation). This isnt totally a problem except it amounts to them pushing fragmented legacy concerns (such as outdated logging concepts) downstream.

All I want is great quality of data for both developers of libraries and developers of applications - those are the customers. I dont see those customers being serviced the best they could be, and I dont see the goals being met _because_ of the distraction, lack of focus, and as far as I can tell, lack of vision of the project.

I think anyone who's working on OTel, if they genuinely had the best interests of the developers in mind, would be hard pressed to answer why Sentry's support isn't an extremely desirable thing given our market reach. The people that care about the project want us involved (and if you're reading this, thank you for constantly pushing us), and I want us to also be involved. So far though we're constantly struggling to actually get an uninstrusive implementation in place that can work with our product, and what I'm asking for would solve for that, but to me looks like a cultural problem and not a technical problem...

The issue is we currently dont see a great incentive to fund a bunch of piecemeal standards that arent relevant to our product, and many library authors are not going to naturally invest into this. Even more say, many of these authors that I've talked to have no excitement what so ever about the standard, or worse, an active distaste. People can say they're wrong, but frankly, that doesnt matter. You dont succeed by thinking someone else is wrong, you succeed by building what your customers wnat.

That is why I would like to see the project focus on problems that people actually have, and do it in a way that doesn't create tradeoffs for developers. To me those problems are the ones that aren't achievable without this level of coordination. They are not shimming another log or metrics collector in place. Those things might be relevant to some people, and thats fine, but we dont need one be-all-end-all project to encompass all sorts of fuzzy semi-related problems.

I may or may not be making sense here, and I'm happy to chat about it more, though HN is probably not a good venue for that.
