KubeCon + CloudNativeCon North America 2024 Co-Located Event Deep Dive: Observability Day

What do you want attendees to get out of this event? What is new and different this year? What will the day look like? Should I do any homework first? Meet your community! Posted on September 19, 2025 by Co-chairs: Eduardo Silva, Austin Parker and Juraci Paixão Kröhling Observability Day traces its roots back to KubeCon Europe 2022 in Valencia, where we hosted FluentCon, a co-located event dedicated exclusively to the Fluentd and Fluent Bit projects. The gathering was a success, and the feedback we received from the community made it clear that we could serve the broader observability space at KubeCon in an even bigger way. To make that happen, we expanded our focus and invited other CNCF projects to join. Just a few months later, at KubeCon US 2022, we introduced Open Observability Day, bringing together maintainers and community members from projects such as Jaeger, Fluentd, Thanos, Prometheus, and OpenTelemetry. The response was overwhelmingly positive, and it quickly became clear that this effort needed to evolve into something more formal and structured. Working closely with the CNCF, that vision became reality—and Observability Day was officially born We want attendees to know that Observability Day is a community-driven gathering where practitioners, end users, and project maintainers come together to shape the future of observability. It’s not just about one tool or project, it’s about learning from each other, sharing best practices, and exploring how the CNCF ecosystem works together to solve real-world challenges. Whether you’re new to observability or deeply involved in projects like Prometheus, Fluent Bit, Jaeger, Thanos, or OpenTelemetry, you’ll leave with practical insights, valuable connections, and a clearer picture of where the space is heading. Most importantly, this is your chance to directly engage with the people building the tools you use every day. What’s new this year is the breadth and depth of community-driven content. Observability Day 2025 puts CNCF projects front and center, with maintainers and practitioners sharing the latest updates and lessons learned. You’ll find talks that go beyond theory—covering real-world scaling challenges, cost-efficient monitoring strategies, and new frontiers like AI observability There’s also a stronger emphasis on OpenTelemetry in action, from rapid adoption patterns to advanced use cases in telco, mobile, and enterprise systems.
