Native NixOS modules under my.profiles.monitoring, enabled on jupiter. Grafana provisions datasources/dashboards/alert rules from the grafana-content flake input (rechberg dashboards repo). Prometheus scrapes host + stack (90d), Loki+Alloy ship the systemd journal (90d). Grafana LAN-only :3000, anonymous viewer, admin password + secret_key via /etc/grafana file providers.
