Sharing Hugo blog posts through Buffer with GitHub Actions

Thu, 08 Oct 2026 00:00:00 +0000

AI-generated article: This walkthrough was generated by AI to document this site’s publishing workflow and test its Buffer integration.

This site uses Hugo and GitHub Pages. After a new blog post deploys, a GitHub Actions workflow sends an announcement to Buffer for sharing on LinkedIn, Mastodon, and Bluesky. Automatic queueing is the goal; the initial testing phase uses drafts to check the text and target accounts before anything is shared. Draft mode remains available as an optional review step.

Creating interactive slides with LLMs, Slidev and Rough.js

Wed, 07 Oct 2026 00:00:00 +0000

I enjoy preparing for presentations: the part where I write the demo, where I outline what I want to talk about and what I want to say. I also like giving the talk. However, I haven’t enjoyed creating slides in a very long time. Neither PowerPoint nor Google Slides allows me to express my ideas on slides in the way I envision it. Or, more likely, I lack the skills to do so, as there are people out there who do magic with those tools.

Observability for Humans and Agents in the AI Age

Mon, 28 Sep 2026 00:00:00 +0000

Nicolas Wörner and I explore how AI agents can help with both OpenTelemetry instrumentation and telemetry analysis. We discuss using skills and code reviews to improve instrumentation, then moving from interactive investigations to automated analysis workflows. Throughout, useful results depend on purposeful instrumentation, clear alerts, and access to reliable telemetry.

Trace Through: End-to-End Observability from Claude Code to Your Tools

Tue, 22 Sep 2026 00:00:00 +0000

Claude Code session traces can leave the tools they invoke disconnected from the agent’s trace. In this episode, I show how to propagate trace context with CLAUDE_CODE_PROPAGATE_TRACEPARENT and connect agent activity, Docker builds, and custom tools into one continuous trace.

The walkthrough covers Claude Code configuration, OpenTelemetry settings for Docker BuildKit and Buildx, and instrumenting your own tools using context propagation through environment variables.

How to Expand the Observable Universe: 4 Techniques Every Developer Should Know | CloudNative Munich

Wed, 09 Sep 2026 00:00:00 +0000

In this talk from the Kubernetes, Cloud Native and Platform Engineering Meetup Munich, I explore observability from first principles and explain how to add OpenTelemetry to applications and their dependencies.

The talk covers trace context, APIs and SDKs, OTLP, and semantic conventions before comparing four automatic instrumentation techniques: monkey patching, bytecode instrumentation, compile-time instrumentation, and eBPF. It also explores native instrumentation, instrumentation libraries, and practical steps for contributing to the OpenTelemetry ecosystem.

Cutting Telemetry Volume Is Not the Same as Cutting Noise

Tue, 08 Sep 2026 00:00:00 +0000

Reducing telemetry volume does not automatically improve signal-to-noise. This article explores the tradeoffs between removing redundant data, losing information needed for investigations, and enriching telemetry to make it more useful. It argues for measuring the questions teams can answer rather than focusing solely on bytes per day.

Metrics are like Champagne

Mon, 10 Aug 2026 00:00:00 +0000

I always thought that metrics were like water. As long as something looks like one and is used like one, it is a metric. However, I was wrong.

Metrics are more like champagne: only what comes from the Champagne region may be sold under the name. Everything else is sparkling wine.

Likewise, metrics are only metrics if they were produced in the Vallée des Métriques. Everything that does not originate from there is just a sparkling roll-up.

Introducing bronto-community: A Place for Projects to Grow

Fri, 07 Aug 2026 00:00:00 +0000

Open source development thrives on remixing existing projects to solve new problems. The author reflects on years of finding projects that almost meet requirements, forking them, and contributing improvements back to the community.

Experience running open source programs at Cisco and working with OpenTelemetry demonstrated that successful projects extend beyond code itself. Decisions about licensing, what to publish, and how projects evolve matter tremendously. The field has accumulated substantial guidance on these questions through established resources.

Reliability from Manual to Autopilot

Wed, 05 Aug 2026 00:00:00 +0000

“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.

Building an Agent with Vercel Eve and Observing it with OpenTelemetry and Bronto

Wed, 22 Jul 2026 00:00:00 +0000

The author attended Vercel Ship conferences and noticed “observability” featured prominently in keynotes. After learning about Eve, Vercel’s new framework for “durable, filesystem-first AI agents,” the author decided to build a practical project combining Eve with OpenTelemetry and Bronto monitoring.

The concrete challenge involved tracking technology events and Call for Papers deadlines scattered across multiple websites. This task required an agent capable of pulling from various feeds, reading details, categorizing events, and integrating with Slack and Jira for team coordination.

Dear first-time contributor

Fri, 17 Jul 2026 00:00:00 +0000

I am not a native English speaker and that’s why I used AI to answer your questions.

I keep seeing this, or a version of it, on issues and PRs. Reading it over and over again, especially when written by first-time contributors, infuriates me, it triggers an irrational anger in me! I am also not a native English speaker, most of the other participants in this conversation aren’t either.

Observability is an infinite game, not a war.

Thu, 09 Jul 2026 00:00:00 +0000

If you’re interested in observability, it is very likely that you read Mat Duggan’s Why Clickhouse is Winning the Observability Wars or one of the follow ups and responses to it, for example Charity Majors’. Both are fantastic articles, and I recommend that you spend the time reading them front to back, give them your attention! And by that I also want to get one thing out of the way, that the title here might suggest: I do not disagree with them, I actually agree wholeheartedly with them on why ClickHouse is the current dominant backend in Observability. And they deserve that spot, as I know first hand from working with their product and knowing some of the great people working on it.

Before I joined Bronto, two things had to be true

Thu, 02 Jul 2026 00:00:00 +0000

I’ve been in the observability space long enough, through OpenTelemetry, by seeing and doing dozens of vendor pitches and enough “AI-powered” demos to last a lifetime. So I have a clear idea about what a company needs to be successful in this area, and what would actually make me passionate about working for one.

He Said Kill Spans On Camera — Hotservability ft. Severin Neumann

Tue, 26 May 2026 00:00:00 +0000

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.

No need for HUMANS.md

Tue, 03 Mar 2026 00:00:00 +0000

A while back I was exploring an open source project I was using, and interested in contributing to, as it provided capabilities I needed but missed some additional ones I wanted to have. Naturally, I was looking for a CONTRIBUTING.md. The file existed, but it only contained a note, that issues and PRs are accepted. While this is key information that belongs in this file, I was missing instructions on how to set up the repository, how to run tests, and what criteria I need to meet to increase my chances of having a PR accepted.

Adjusting load generators for realistic traffic simulation

Mon, 23 Feb 2026 00:00:00 +0000

Throughout my jobs in the observability space, I created or contributed to various demo and sample applications, which often follow the same premise: there is a “normal state” in which the application is running, and with a trigger, it moves into a “deviated state”. For example, there is the placeOrder transaction on a webshop that performs just fine, and orders and money are flowing into our hypothetical e-commerce company. However, with the click of a button (or a CLI command), an issue is injected into the application, and the placeOrder transaction stops working as expected. Orders go down, money stops flowing, hypothetical customers get angry!

Reliability Is Managed In Services, But Felt In Transactions

Thu, 19 Feb 2026 00:00:00 +0000

Modern reliability practice is excellent at making complex systems operable at the service level, but users experience reliability at the level of end-to-end transactions and flows. This post explores why that gap exists and what it means for how we measure and manage reliability.

Are metrics the bestrics?

Tue, 10 Feb 2026 00:00:00 +0000

“What’s your favorite telemetry signal” has been the last question of the Humans of OpenTelemetry series for the last few years. At KubeCon EU 2024 my answer to this was “profiling, because I think this is really closing a big gap that was missing in observability”. But, today, I found out that my answer has changed, and I am leaning more toward what Vijay Samuel gave as an answer: “I feel metrics are the most powerful signal!”

How to Turn Slow Queries into Actionable Reliability Metrics with OpenTelemetry

Wed, 04 Feb 2026 00:00:00 +0000

Slow SQL queries degrade user experience, cause cascading failures, and turn simple operations into production incidents. Instead of collecting more telemetry for its own sake, this guide shows how to turn OpenTelemetry database spans into span-derived metrics you can actually act on.

Why a Major AI Incident Is Coming in 2026

Wed, 04 Feb 2026 00:00:00 +0000

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.

Can you get Observability without Telemetry?

Thu, 18 Dec 2025 00:00:00 +0000

People always say there are no stupid questions, and then you read the title of this post and you’re not so sure anymore. You start to doubt my sanity, or at least suspect that I’m a troll. However, as it is with most apparently stupid questions, there is something to learn from the answer if you explore it. To spare you from reading the rest of this, the short answer is “Yes, but…” and the long answer is more of a theoretical observation with some linguistic subtleties. So if you’re not interested in that, you can leave and do something fun, otherwise don’t say I didn’t warn you!

When the Hunt Feels Good: Fixing the Incentives in Incident Response

Tue, 16 Dec 2025 00:00:00 +0000

Every on-call engineer knows the hunt: a late-night incident where you chase down a mysterious failure, clue by clue, until you finally pin down the culprit. There’s real craft in that work: staying calm, forming hypotheses, ruling things out, communicating clearly, and bringing customers back to safety. When it’s over, the afterglow is real: a mix of pride, relief, and the feeling of being useful when it mattered.

And yet, the same incident that becomes a great story is rarely a great night. It costs sleep, weekends, and family plans. Most people don’t love the disruption. They love the moment when a hard problem finally makes sense. The trap is subtle: because the story is vivid and the relief is rewarding, the reactive hunt can end up feeling more visible than the quieter work that would have prevented the incident in the first place.

eAfterWork EP 9: What Every Leader Needs to Know

Wed, 03 Dec 2025 00:00:00 +0000

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.

Purposeful OpenTelemetry

Wed, 26 Nov 2025 00:00:00 +0000

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

Splitting out a monolith into multiple services in OpenTelemetry

Tue, 25 Nov 2025 00:00:00 +0000

I did an experiment on splitting out a monolithic application into multiple “virtual services” in OpenTelemetry to have modules visualized independently on service maps.

I am not sure if this is a good idea and something you should replicate in practice, since it might violate some best practices. However, I wanted to see how I can do it. Since (as far as I know) all otel backends are only able to provide such a map/graph visualization using service.name from the resource attributes, I tried out what happens if I create one TracerProvider per module with module-specific service.* attributes.

Why Traditional SRE Breaks in Kubernetes Scale

Mon, 17 Nov 2025 00:00:00 +0000

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.

What is context propagation, why do I need it, and what does it have to do with metrics?

Fri, 31 Oct 2025 00:00:00 +0000

When you’re heads-down in your own area of expertise, it’s easy to forget that what’s obvious to you might not be to others. As you might have seen in previous posts, I learned that for me using pen and paper from time to time helps uncover unknown knowns in my head. Last time, it was why the three pillars need to go. This time, it’s context propagation, and its surprising relationship to metrics.

Do You Even Need Kubernetes for Reliable Service Delivery?

Mon, 27 Oct 2025 00:00:00 +0000

Kubernetes has become the default backbone of cloud native architecture. But does it actually help you ship services more reliably, or is it just more moving parts?

Thank you, three pillars of Observability. You served us well.

Thu, 02 Oct 2025 00:00:00 +0000

I just read another post introducing traces, metrics, and logs using that analogy, which reminded me to re-share that excellent piece by Ted Young on The New Stack from a few years ago:

Modern Observability Is a Single Braid of Data

Ted argued the pillars are no longer load‑bearing and suggests a better framing: the “Single Braid of Data”.

So let’s wheel the pillars into the museum, rope off the exhibit, and hang a small plaque: “Historic framing.” As we do with once‑cherished pillars that are no longer load‑bearing.

Expanding the observable universe

Mon, 19 May 2025 00:00:00 +0000

I have a confession to make: I struggled for a long time with the statement: “Observability helps you uncover unknown unknowns.”

It never quite sat right with me. If you can uncover an “unknown unknown” using Observability, wasn’t it always, in some sense, a known unknown? Or perhaps even an unknown known you just hadn’t noticed?

That logical loop kept bothering me.

Recently, I realized where my understanding failed, and thought this might be worth sharing:

Automate Maintainer Tasks With GitHub Actions

Thu, 17 Apr 2025 00:00:00 +0000

Maintenance involves functional checks, servicing, repairing, or replacing necessary devices, equipment, machinery, building infrastructure, and supporting utilities

This definition from Wikipedia aptly describes what we, as maintainers, do. A significant portion of our time is spent on upkeep. While some of this work is enjoyable, many tasks are tedious and exhausting.

To alleviate this, we are exploring ways to automate some of these tasks. One popular option is incorporating GitHub Actions into our repository.

Tutorial: Exploring the Power of OpenTelemetry on Kubernetes

Mon, 01 May 2023 00:00:00 +0000

Deploying an end-to-end observability system comes with many challenges. The organization has to decide how data will be collected, what data formats will be used, sampling strategies, filter sensitive data (a.k.a. PII), and ultimately send data to the observability platform of their choice. In this session, we will teach you how to roll out end-to-end observability data collection on Kubernetes using the OpenTelemetry project. You will learn how to effectively instrument applications using auto-instrumentation, deploy the OpenTelemetry collector, and collect traces, metrics, and logs. You will gain the knowledge needed to tackle the mentioned challenges. After this session, you will be able to understand and use OpenTelemetry instrumentation libraries, collector and Kubernetes operator.

A modified parallel F4 algorithm for shared and distributed memory architectures

Wed, 19 Jun 2013 00:00:00 +0000

In applications of symbolic computation an often required but complex procedure is the computation of Gröbner bases and hence it is obvious to realize parallel algorithms to compute them. There are parallel flavours of the F4 algorithm using the special structure of the occurring matrices to speed up the reduction. In this paper we start from this and present modifications allowing efficient computations of Gröbner bases on parallel architectures using shared as well as distributed memory. To achieve this we concentrate on one objective: reducing the memory consumption and avoiding communication overhead. We remove unrequired steps of the reduction, split the columns of the matrix in blocks for distribution and review the effectiveness of the SIMPLIFY function. Finally we provide benchmarks with up to 256 distributed threads of an implementation which will be available at https://github.com/svrnm/parallelGBC.

Parallel Reduction of Matrices in Gröbner Bases Computations

Mon, 03 Sep 2012 00:00:00 +0000

In this paper we provide an parallelization for the reduction of matrices for Gröbner basis computations advancing the ideas of using the special structure of the reduction matrix. First we decompose the matrix reduction in three steps allowing us to get a high parallelization for the reduction of the bigger part of the polynomials. In detail we do not need an analysis of the matrix to identify pivot columns, since they are obvious by construction and we give a rule set for the order of the reduction steps which optimizes the matrix transformation with respect to the parallelization. Finally we provide benchmarks for an implementation of our algorithm. This implementation is available as open source.
