Metrics Applied
summary
Describes concrete observability practices: collect logs plus three metric types, build dashboards, and connect alerts to incident workflows using Prometheus, Grafana and Alertmanager. Shows a ping prototype that exposes counters and histograms, scrapes services, computes 95th‑percentile latencies, aggregates and stores histograms for queries, scales to tens–hundreds of GB of real‑time data, and maps alerts to explicit actions in production.
