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

@opentelemetry is officially a CNCF graduated project! 🎓🎉 OpenTelemetry has become the trusted de facto observability standard helping teams gain better visibility across distributed systems. Congrats to this incredible community! Read more about the milestone here: https://bit.ly/4fvcHAb

📣 OTel Unplugged is headed to Brussels in February 2026! A full day of in-person conversation and collaboration! Unconference sessions only—no organized talks. We’ll shape the next chapter of the #OpenTelemetry roadmap. Details on registration and sponsorship in our latest blog. buff.ly/vC9kqtZ

Check out this week's o11y newsletter with useful guidance and context all things OpenTelemetry, Prometheus, and wider observability topics: o11y.news/2025-07-21/ #observability

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...

Note to self. Do not write the post directly on the platform. 1 misclick and everything can be lost. 1 click. Everything!

Perfeito!!!

The results are in! Check out our latest blog post that reports the findings of the #OpenTelemetry Developer Experience Survey. Thank you to the 218 participants! Your feedback will help improve #OTel #DevEx in key areas, including docs, SDKs, and the Collector.

Better than one good comment, is two good comments!

Do you work with OTel? Have an interesting case to share? Wanna talk about some area in depth? Or maybe about how to scale for Otel? The CPF for the OpenTelemetry Community Day is closing next week! Make sure to submit your talk sessionize.com/otel-communi...

I'll be speaking about "The State of OpenTelemetry Profiling" with Damien Mathieu at KubeCon EU's Observability Day on April 1st in London. I'd love to meet as many people as I can while I'm there. Ping me if you're in town! I'll be around from Monday evening until Wednesday evening.

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.

Give it a try and let us know what you think! Happy demoing! 🥳

Built-in OpenTelemetry! Looking forward to seeing more and more of this!

At @datadoghq.com we are always hiring. We are looking for a new fellow to work on our agent and OpenTelemetry! Ping me if you want to know more. careers.datadoghq.com/detail/65977...

The open standards underpinning @opentelemetry.io create the necessary conditions for OSS to deliver on its promise of industry collaboration. Very happy about this new project forming. What a great start for #observability in 2025! 🎉

@jcosta.dev and I and our lovely colleague JC whom I do not have on bsky wrote a thing explaining how to get started with OTEL+Rust. There are a few decision points in monitoring a Rust service, and I hope this condenses it down for others!

The only pic that captured my November mustache! Thanks @metalmatze.de!

Waiting for my flight to #Berlin. I'm presenting at the #OTelNight and pretty excited to meet the local community. The event is booked out with some folks on the waiting list. Pretty hyped about it and hoping the Demo works 😅 Thanks @jpkroehling.bsky.social for organising it! #OpenTelemetry

If you watch Observability talks I have honest question to you. What do you miss?

Not at #kubecon, but it is nice seeing that I'm still there somehow. I'm listed as one of top 100 contributors to @opentelemetry.io. Can you spot @julianocosta89 there?

I wrote about my collab with @joinmastodon.org.web.brid.gy and @opentelemetry.io. The blog has a couple of Collector configs and I also talked about the #OpenTelemetry Collector Builder (OCB), which didn't land in the project, but it was worth mentioning. Check it out: jcosta.dev/posts/mastod...
