OpenTelemetry in 2023
> OpenTelemetry is a marketing-driven project, designed by committee, implemented naively and inefficiently, and guided by the primary goal of allowing Fortune X00 CTOs to tick off some boxes on their strategy roadmap documents.
I'm the founder of highlight.io. On the consumer side as a company, we've seen a lot of value of from OTEL; we've used it to build out language support for quite a few customers at this point, and the community is very receptive.
Here's an example of us putting up a change: https://github.com/open-telemetry/opentelemetry-js/pull/4049
Do you mind sharing why you think no-one should be using it? Some reasoning would be nice.

OpenObserve: Elasticsearch/Datadog alternative in Rust.. 140x lower storage cost
That's traces? I was wondering if I could use https://github.com/open-telemetry/opentelemetry-js/tree/main...

OpenObserve: Open source Elasticsearch/Datadog/Splunk alternative in Rust for logs. 140x lower storage cost
Nothing like Faro for now. However, https://github.com/open-telemetry/opentelemetry-js can be used to achieve the same result and OpenObserve has great support for Opentelemetry.

Logs and tracing: not just for production, local development too
4. Register automatic instrumentations. For example, you can automatically trace all XHR requests, fetch requests, page loads, and user interactions. With distributed tracing, you should always prefer automatic instrumentation whenever possible to reduce maintenance and leverage existing conventions. The document load instrumentation allows you to treat the server as the parent span to a given page load, from which the client will then be the root span to everything in the server. This is an extremely powerful concept that allows traces to viewed from the perspective of the user, encapsulating all requests and user interactions in a single trace with no manual instrumentation!
We also trialed Sentry's APM tool (also marketed as a distributed tracing tool). While it had pretty charts, dashboards, niceties like core web vitals, and integrated well with Sentry's error product, its utility as a distributed tracing tool is significantly less powerful than tools like Honeycomb. You will end up using a large amount of your user's bandwidth sending telemetry data that can't fully be leveraged in the Sentry UI. When I last used (in April 2021), the spans of a given trace could only be viewed in a specific part the UI and they couldn't be searched for in queries or used in charts. I'm unsure if this has been updated. But this is not the worse part. Because Sentry uses its own data model for traces, it is not compatible with open source standards such as OpenTelemetry or OpenTracing! The sales team will not tell you this during the trial. This means our entire backend, which was already instrumented with OpenTracing, would now also need to instrument Sentry's tracing (...if they supported the language) in order to connect frontend traces to backend traces. Each team I met with their sales team, I said the same thing: support OpenTelemetry, otherwise you are asking for us to further isolate our backend and frontend teams.
It looks like they have heard this opinion, as they have recently published a blog post about the evolution of the distributed tracing API, citing incompatibility with OpenTelemetry due to their data model. It will require a very large change for them to support this. Meanwhile, OpenTelemetry can be used with any tracing vendor, a large number of languages, the other major instrumentation standards (OpenTracing, OpenCensus), and any trace propagation format.

Monitoring consumer lag in Azure Event Hub
Consumer lag will quickly show any functional or technical issue with your event stream. By using the code examples from this blogpost, you can avoid having to dive into the SDKs yourself. Of course, you can adopt the metric collection to send the metric to the logs or to another metrics system like prometheus, datadog, or open telemetry.

Any good tutorial showing you which library to use for dependency injection in a project?
I would work on getting Open Telemetry pointed at an “all-in-one” Jaegar instance and move on from there: https://www.jaegertracing.io/docs/1.25/getting-started/ https://github.com/open-telemetry/opentelemetry-js Various cloud providers may have a way to collect/view traces as well, but, Jaegar and the Open Telemetry Collector are the open source way to do that. The projects are in the process of converging in some ways — everything is in flux.

Distributed Tracing 101 for Full Stack Developers
OpenTelemetry is a collection of open source tools, APIs, and SDKs for instrumenting, generating, and exporting telemetry data from running software. It provides language-specific implementations for most popular programming languages, including both browser JavaScript and Node.js.

It's 29 Delphi, I mean
Indeed, webapps are not immune to distribution problems. Wayward and invasive browser extensions are a clear threat, as are 3rd-party dependencies (and their dependencies) loaded at runtime. Which is why companies like https://sentry.io exist. I think the difference is that webapps are "distributable by default" and it takes real work to break this. Versus having local desktop apps which require work to distribute. A potent example of the power of defaults.

The Life and Death of Open Source Companies
> You invent something, and then immediately turn it into a cheap commodity by releasing it for free.
Exactly. A 71-line python script https://github.com/getsentry/sentry/commit/3c2e87573d3bd16f6... was groundbreaking when it came out and the fact that it springboarded into a startup is commendable.

Sentry Relicense Again (FSL)
https://github.com/getsentry/sentry/pull/60144 -> https://github.com/getsentry/sentry/blob/d4d89e2fa93ad99f13d...
If they're going to all this trouble for "ambiguity," I don't know why they wouldn't further extend their custom SPDX identifier to include the "2 year" rollover, since that's one of their pearl-clutching reasons for this bullshit: https://github.com/getsentry/loose-confederation/issues/4

Sentry: From the Beginning
It's source available under the BSL: https://github.com/getsentry/sentry. After four years it becomes open source (probably to prevent "AWS Elastic Error Handling service(tm)" from becoming a thing)
You can still run it for your company for free, if you feel like managing all of the infra it requires.

Flash-cards app with OpenAI
Ohh, I forgot to mention that I added Sentry in this project just because it is an easy way to track the errors. But don’t worry, it is free and you can create it here.
