Observability Day

Observability Day is a vendor-neutral gathering of the CNCF observability community. Maintainers, operators, and end users of Prometheus, Fluentd and Fluent Bit, OpenTelemetry, Jaeger, Thanos, Cortex, Perses, Pixie, Kepler, Inspektor Gadget, and the wider ecosystem come together as peers to share how cloud-native systems are observed, debugged, and operated at scale. Talks span project internals, cross-project architectures, the data engineering required to make telemetry useful and affordable, and emerging frontiers such as AI and agent observability, eBPF-based instrumentation, and CI/CD and platform telemetry. The day favors experience-driven content: real architectures, real trade-offs, and the open source tools that make modern observability possible.

This event is one of our KubeCon + CloudNativeCon Europe CNCF-hosted Co-located Events. In-person attendees have the option to register for an All-Access In-Person KubeCon + CloudNativeCon pass that will include entry to ALL CNCF-hosted co-located events + KubeCon + CloudNativeCon.

Observability Day topics include:

• Project deep dives
• Telemetry pipelines and data engineering
• Observability cost, quality, scale, and efficiency
• AI and LLM observability
• eBPF, zero-code, and kernel-level observability
• CI/CD, platform, and developer-experience observability
• End-user stories: production deployments, migrations, and operations
• Correlation, context, and cross-project architectures

Submission Types:

• Presentation: 25 minutes with 1 or 2 speakers presenting on a topic
• Panel Discussion: 35 minutes of discussion amongst 3 to 5 speakers (In an effort to promote speaker diversity, CNCF does not accept submissions with all-male panels, and three different organizations must be represented).
• Lightning Talk: A brief 10-minute presentation with a maximum of 1 speaker
