Ray Serve’s New Grafana Dashboard: Debugging That Wasn’t Possible Before

Ray Serve's new Grafana dashboard, introduced with Ray v2.54+ on the Anyscale platform, significantly enhances production debugging capabilities by offering a comprehensive view of system performance and lifecycle states, thus transforming the debugging workflow. This dashboard replaces the legacy version and allows users to quickly diagnose issues such as latency spikes, deployment problems, and autoscaling inefficiencies by visualizing application status timelines, replica health, and request paths in real-time. The dashboard provides insights into distinct aspects of the system, enabling users to identify whether issues stem from deployment procedures, runtime conditions, or specific layers such as routing and queueing. Furthermore, with the upcoming Ray 2.55 release, Anyscale users will benefit from seamless navigation from the Grafana panels to Anyscale's Log Viewer, optimizing the debugging process by correlating metrics spikes with detailed logs. This integration aims to reflect operational maturity by helping users to pinpoint problems and their root causes effectively, ultimately facilitating a shift from speculative to informed decision-making in production environments.
