Cedric Ziel developed a server-timing header integration for the grafana/hackathon-dragndrop-grafana repository, focusing on enhancing observability and performance monitoring for the Faro Web SDK. By injecting server-timing headers into backend responses using Go, Cedric enabled precise correlation between server-side request timings and client-side navigation events. This approach allows teams to diagnose performance bottlenecks more effectively and lays the groundwork for future optimization cycles. Cedric’s work centered on backend and API development, with an emphasis on performance monitoring, and addressed the need for data-driven insights by making server and client telemetry directly comparable within the existing monitoring infrastructure.
