 # Ingress: Traefik + cert-manager (same pattern as `clusters/noble/bootstrap/headlamp/values.yaml`).
 # Service links match **`ansible/roles/noble_landing_urls/defaults/main.yml`** (`noble_lab_ui_entries`).
 #
-# UI: **`siteMonitor`** on each link (HEAD/GET latency + status). **`widgets`**: datetime, Kubernetes
-# (cluster + node CPU/memory), Prometheus (scrape targets), search. **`enableRbac`** enables the
-# Kubernetes integration (in-cluster ServiceAccount).
+# **`siteMonitor`** runs **server-side** in the Homepage pod (see `gethomepage/homepage` `siteMonitor.js`).
+# Public FQDNs like **`*.apps.noble.lab.pcenicni.dev`** often do **not** resolve inside the cluster
+# (split-horizon / LAN DNS only) → `ENOTFOUND` / HTTP **500** in the monitor. Use **in-cluster Service**
+# URLs for **`siteMonitor`** only; **`href`** stays the human-facing ingress URL.
 #
-# Prometheus URL: in-cluster DNS for **kube-prometheus** release — adjust if your Service name differs
-# (`kubectl -n monitoring get svc | grep prometheus`).
+# **Prometheus widget** also resolves from the pod — use the real **Service** name (Helm may truncate to
+# 63 chars — this repo’s generated UI list uses **`kube-prometheus-kube-prome-prometheus`**).
+# Verify: `kubectl -n monitoring get svc | grep -E 'prometheus|alertmanager|grafana'`.
