Explains a concrete dashboard recipe: capture metrics with StatsD, store with Graphite, visualize in Grafana via a Docker demo on Katacoda. Implements a tiny API that returns 200/500 and timers, builds graphs for rate/error/duration (RED and Google four golden signals), and shows counts as bars and durations as a right-axis line. Cites a production incident with ~78 errors and a Kinesis iterator spike to ~42 that the dashboard surfaces within minutes, enabling a restart fix and later code correction.
