OTel Community Day + Open Observability Summit: One Big Day for Open Source Observability
On June 26, 2025, OTel Community Day and Open Observability Summit are joining forces at Open Source Summit North America. The OpenTelemetry governance and technical committees, along with project maintainers, are excited to present two community-led tracks, one co-located event, and a shared goal: bring the observability community together to collaborate, learn, and shape the future of open source observability.
Open Observability Summit is for developers, operators, and technical leaders who rely on open source to gain deeper insight into their systems. Every session is grounded in real-world experience and shaped by the community. Expect hands-on learning, practical talks, and open dialogue.
OTel Community Day is a space for the OpenTelemetry community to celebrate wins, share knowledge, and connect over where observability is headed. Our contributor experience survey results show that OTel contributors are excited to collaborate in person, where they can not only learn from each other and but also help end users with practical insights and real-world examples. Whether you’re building OTel or building with it, you’ll find your people here.
