Learn how to add OpenTelemetry to every Go-based package on Gentoo transparently at compile time. We walk through installing the OpenTelemetry collector and Go compile-time instrumentation via emerge, modifying make.conf, and testing the telemetry data with Caddy. Find the repo at ote.li/gentoo.
“AI SRE” is everywhere right now — but what does it actually mean to automate reliability, and how far can we really take it? In this talk from Cloud Native Karlsruhe, I break down the hype around AI SRE by comparing it to a discipline that has already gone through decades of automation: autonomous driving. Just like cars combine deterministic systems (anti-lock brakes, gearboxes) with AI-driven ones (adaptive cruise control, lane keeping), reliability engineering needs the same nuanced mix — not a single LLM doing everything. ...
Severin Neumann walked into Hotservability as an OTel governance committee member and docs maintainer. He walked out as the man who said “kill spans” on camera while sweating through a habanero reaper sauce. This episode has everything. A NodeJS agent outage that 10x’d response times. A controversial opinion about spans that will make OTel people lose their minds. A defense of metrics so passionate it almost turned into a debate. And somehow, he made it to the Last Dab. ...
In this TFiR 2026 predictions conversation, I talk about why system complexity is outpacing our ability to manage it, why 50% observability data reduction won’t be enough, and why we’re likely to see a major AI-related incident in 2026 if we don’t put better guardrails in place.

In this episode of eAfterWork, Severin Neumann, OpenTelemetry maintainer, member of the OpenTelemetry Governance Committee, and one of the people who writes and maintains the official OpenTelemetry documentation, helps us understand why OpenTelemetry matters for both technical and non-technical leaders, how it’s shaping the future of observability, and what you really need to know to make the right decisions.
Organizations collect far more telemetry than they use. The result? Exponential costs, PII risks, and still no root cause when incidents happen. In this technical session, Yuri Oliveira (OllyGarden) and Severin Neumann (Causely) demonstrate: How to identify instrumentation problems at the source Why traces and semantic conventions enable purposeful telemetry How quality telemetry enables causal reasoning at scale
AI-powered SRE isn’t about throwing alerts into an LLM and hoping it magically fixes production. In this conversation from KubeCon + CloudNativeCon in Atlanta, Severin Neumann, Head of Community at Causely, explains why real AI-SRE starts long before an incident ever happens. Neumann breaks down how teams can shift reliability left, predict failures before rollout, and rely on deterministic causal reasoning instead of correlation-driven LLM guesses. He also explains why many SRE teams burn hours chasing hallucinated remediation paths — and how causal models eliminate that risk. ...
Been too busy to keep up with what’s going on in the OTel space? No worries—we’ve been there, too! That’s why we’ve put together this new series for you (and for ourselves). Catch up on significant updates to the project, connect with special guest maintainers, and get the chance to ask questions during the audience Q&A. Join us for the very first episode, where we’ll chat with special guests Severin Neumann, OpenTelemetry GC & Maintainer, and Marylia Gutierrez, Contributor Experience Maintainer & JS SDK Approver, about the latest and greatest in OTel. ...

The interview with Severin Neumann examines his journey from writing his first line of code in PHP 3.0 to becoming a key figure in the world of OpenTelemetry. Severin shares insights into his career path, including his involvement with AppDynamics and Cisco, and his current role at Causely, where he focuses on Open Telemetry and causal reasoning for root cause analysis.
