Metrics

An opt-in Prometheus and Grafana stack that scrapes Traefik's /metrics endpoint:

srv metrics enable
#   https://grafana.local      (admin / admin)
#   https://prometheus.local
srv metrics status
srv metrics disable

Both UIs are routed through Traefik with local TLS; no loopback ports are exposed. Grafana comes with a Prometheus datasource already wired; import dashboard ID 17347 for a per-router Traefik overview.
