# Episode 4: Prometheus

## **Cloud-Native Metrics with FinOps-Grade Governance**

The first episode of Arc 2 treats Prometheus not as a monitoring tool but as the metrics substrate of the entire observability stack. PromQL for FinOps, kube-prometheus-stack as a reference deployment and the governance layer that turns raw metrics into actionable cost data.
