The OpenTelemetry Demo 3.0 is out, and yes, we broke it! In this blog post we share the highlights of what changed in the 3.0 release. And if you're a vendor using the Demo to showcase your OTel support, here's your call to action: Please update your instructions. buff.ly/gSt6uFX

We broke the OTel demo
If you’ve been running the Demo for some time, you may have seen a couple of structural changes lately, and you may even have gotten mad about things not working as expected. We feel your pain and we…

I’m not an Azure expert, but doesn’t azure support OTLP? I know that Microsoft is one of the biggest contributors to OTel, maybe it would worth checking that out.

You can use the `opentelemetry-distro` with an exporter. Those are just 2 packages. Then you start your app with: ``` RUN opentelemetry-bootstrap -a install ENTRYPOINT [ "opentelemetry-instrument", "python", "app.py" ] ``` I ran a lab 9months ago, here is a sample: github.com/julianocosta...

Using OpenTelemetry Collector Contrib in prod? You’re not alone! ~90% of 1,000+ companies we analyzed are too. The thing is that it is not meant for prod use (the README says so!). Maybe it’s time we rethink this. Check out the full blog post: www.datadoghq.com/blog/otel-co...

I wonder why people keep writing on Medium. It has a paywall and, you most probably will never see a cent of it. I open the article, read the intro, then Medium comes in and say, you have to be logged in, or pay to read. I close it, and keep on with my life. You just lost a reader.

Any tips on how to solve when 2 projects want to become "The Standard" and in the end both are just 2 different ways of doing the same? We are currently facing that with OpenTelemetry Rust and Tokio/Tracing. Both have advantages and disadvantages, but it seems that merging the two won't happen 😔
