OpenSearchCon EU - Fluent Bit & OpenSearch: The Power Couple of Open Source Observability

After my adventures with the OpenSearch maintainers and developers in their booth at KubeCon NA this year, I was excited to share the results of our adventures at their OpenSearchCon EU event.

So with full enthusiasm I submitted a session about the observability power couple that is Fluent Bit and OpenSearch when used together. This would provide the attendees with a good overview of what the CNCF graduated project Fluent Bit, an end-to-end observability pipeline, can do for them. 

To complement and visualize your pipeline telemetry data, OpenSearch was added to the mix and we worked hard to provide a streamlined demo project providing the hands-on experience of setting up the entire integration. 

Let's look at the session and supporting hands-on learning content we are providing.

KubeCon EU 2026 - From Hallucinations to Hardware: Diagnosing LLM Failures

I'm excited to share that a talk I submitted, with my good friend Ryan Peirce, was accepted to Cloud Native AI & Kubeflow Day! 

In case you were still unaware, KubeCon + CloudNativeCon is the flagship conference of the Cloud Native Computing Foundation (CNCF), gathering adopters and technologists from leading open source and cloud native communities. The event brings together the entire cloud native ecosystem for education, collaboration, and networking opportunities.

Every year this event features multiple co-located events, and we're excited to be presenting at Cloud Native AI & Kubeflow Day, which focuses on the intersection of cloud native technologies and artificial intelligence workloads.

Below are all the details of our session at the time of this writing.

Mastering Fluent Bit: Developers Guide to Forwarding Metrics with Prometheus Remote Write

 This series is a general purpose getting started guide for those of us wanting to learn about the Cloud Native Computing Foundation (CNCF) project Fluent Bit.

Each article in this series addresses a single topic by providing insights into what the topic is, why we are interested in exploring that topic, where to get started with the topic, and how to get hands-on with learning about the topic as it relates to the Fluent Bit project.

The idea is that each article can stand on its own, but that they also lead down a path that slowly increases our abilities to implement solutions with Fluent Bit telemetry pipelines.

Let's take a look at the topic of this article, integrating Fluent Bit with Prometheus. In case you missed the previous article, check out the developer guide to monitoring health metrics with Prometheus where you explore how to monitor the health of your telemetry data pipelines.

This article will complete our hands-on exploration of Prometheus integration, helping developers leverage Fluent Bit's powerful metrics capabilities. We'll look at the final pattern for integrating Fluent Bit with Prometheus in your observability infrastructure.

DevOpsCon Amsterdam 2026: It’s my docs, and I will cry if I want to!

My last DevOpsCon event was in Munich, so when I saw they were expanding and visiting my home country in Amsterdam, Netherlands I could not resist. I submitted a few things and the one that was selected is a talk I'm going to be testing based on my experiences over the last year as a maintainer on the Fluent Bit CNCF project.

I will be on-site at the Van der Valk Hotel Amsterdam-Amstel for DevOpsCon Amsterdam from 20-24 April 2026. They will have networking, sessions, and hands-on workshops available for all who attend.

Below you'll find my talk details and the schedule.

2025 Year in Review: Community, Contribution, and Changes

As we ease into the last few days of 2025, I like to close out this one last task: reflecting back on all the fun, challenges, and travel over the past year. While it takes a bit of research to gather all the facts and figures, it’s a rewarding effort. I’ve been sharing on this site for two decades now—no ads, no ulterior motives—just an honest effort to communicate with the world.

This year, the focus for me and my teams remained on the four pillars of our role: speaking, publishing, socializing, and hands-on content generation. 

While 2024 was about observability (o11y) taking center stage, 2025 was the year we put those theories into practice, accelerated our momentum, and stated to gain serious traction in the wild.
