KubeCon + CloudNativeCon Europe 2026 Co-located Event Deep Dive: Observability Day

Who will get the most out of attending this event? What is new and different this year? What will the day look like? Should I do any homework first? Find your community! Posted on March 13, 2026 by Co-chairs: Austin Parker, Eduardo Silva, Juraci Paixão Kröhling, Iris Dyrmishi CNCF projects highlighted in this post Observability Day has become a cornerstone gathering for the cloud native observability community. The event evolved from FluentCon at KubeCon Europe 2022 in Valencia and Open Observability Day at KubeCon North America 2022, bringing together maintainers and practitioners from projects such as Prometheus, Fluentd, Fluent Bit, OpenTelemetry, and Jaeger. Observability has come a long way and is now at an inflection point. The ecosystem is converging around shared standards like OpenTelemetry while long-standing projects continue to evolve to meet new scale requirements, cost pressures, and AI-driven workloads. Practitioners running observability in production and platform teams building internal developer platforms will benefit most from Observability Day. The program is heavily oriented toward real-world case studies and production-grade patterns, making it especially valuable for teams operating at scale. At the same time, the two-track format supports newcomers with introductory sessions alongside advanced deep dives. Maintainers and contributors to CNCF observability projects will also find value in the project updates and in-person collaboration opportunities throughout the day. This year’s program reflects how observability is expanding beyond traditional monitoring into AI systems, cost efficiency, and large-scale telemetry engineering. Sessions explore AI trace analysis, AI-enabled explainers, profiling innovations, sustainable Kubernetes infrastructure, high-volume logging strategies, column-store storage architectures, and advanced sampling techniques. There is strong representation across the ecosystem, alongside end-user case studies from organizations operating observability at real production scale. The program highlights both the continued evolution of established projects and the growing intersection between observability and Cloud Native AI.
