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…

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'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! 🥳

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!

Felix Geisendörfer@felixge.de · 2y ago

Manually instrumenting Go applications for observability has always been a time-consuming challenge. Solutions based on binary patching and eBPF have attempted to solve this, but they often come with undesirable tradeoffs. That’s why we built Orchestrion … 🧵

Next up @jcosta.dev

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...
