Observability 2.0 centers around “wide events,” breaking down the silos between metrics, logs, and traces. This article outlines the core ideas and technical challenges of this new paradigm, and introduces how GreptimeDB, a native open-source database for wide events, provides a unified and efficient foundation for next-gen observability platforms.

We benchmarked the overhead of OpenTelemetry in a high-load Go application and compared it to eBPF-based instrumentation. The results may surprise you - tracing adds cost, but it’s not always a dealbreaker

The history of observability tools over the past decade has been about a pretty simple concept, but LLMs bring the death of that paradigm.
