Dashboards with Grafana: RED and USE Dashboards, Variables, Exemplars from Metrics to Traces and Dashboards as Code
A good Grafana dashboard answers one question: RED shows a service's health, USE shows resource saturation. We keep two dashboards for Bookstore as JSON in Git and load them with provisioning, feed variables from target_info and use exemplars to jump from a p99 spike to the trace of a slow request, and we measure why tail sampling leaves most exemplars without a trace.
