The Prometheus monitoring system
summary
Prometheus is a single Go binary monitoring system and TSDB that proves useful specifics: it replaces New Relic for a Rails stack, adds node exporter and local statsd aggregators, and uncovers 70% of statsd events lost until UDP was fixed. It uses a pull model with push vs pull tradeoffs, a label-based dimensional model, a PromQL for rates and error percentages, recording rules plus alertmanager, float64 storage and no clustering, and a working case of dashboards and per-controller latency and error alerts.
