Open Source Observability Day 2026

About

Open Source Observability Day is a free online event devoted to the open tools and practices that help teams understand how their systems behave in production. Produced by inhand.studio under the motto "Open Tools, Open Minds, Open Observability," it targets developers, site reliability engineers, platform engineers and observability practitioners who rely on community-driven software rather than closed monitoring suites. Now in its third year, the event runs as a virtual programme of practitioner talks, typically thirty to forty-five minutes each, spread across a compact schedule. Topics range across distributed tracing, metrics and log management, alerting and incident response, Kubernetes and cloud-native observability, eBPF, database monitoring and cost optimisation. Projects such as OpenTelemetry, Prometheus and ClickHouse feature prominently, reflecting the stack many engineering teams now assemble themselves. Because the sessions emphasise real-world case studies, attendees come away with concrete patterns for instrumenting services, managing telemetry volume and building dashboards that support faster troubleshooting. Remote attendance also makes it easy to sample individual talks without committing to travel. As open-source observability matures into a default choice for many organisations, this online SRE and monitoring conference gives the community a dedicated venue to share hard-won operational knowledge.
