+# Monitoring and Observability
+
+[← Back to Main README](../README.md)
+
+This section covers the deployment of a centralized monitoring and observability stack across the homelab cluster using Prometheus, Grafana, and Node Exporter, culminating in live-embedded metrics on the Rapture portal homepage.
+
+---
+
+## 1. System Architecture
+
+The telemetry stack consists of three layers:
+
+1.  **Metrics Collection (Node Exporter):** Runs as a host-networked Podman container on all four VMs, exposing raw OS metrics (CPU, RAM, disk, network) on port 9100.
+2.  **Time-Series Database (Prometheus):** Runs on ansible-control (172.30.1.200:9091), scraping metrics from all node exporters every 15 seconds.
+3.  **Data Visualization (Grafana):** Runs on ansible-control (172.30.1.200:3001), visualizing metrics from Prometheus.

+        web["web-portfolio (172.30.1.201)"] -->|port 9100| prom
+        media["media-stream (172.30.1.202)"] -->|port 9100| prom
+    end

+        user["User Browser"] -->|HTTPS| portal["Rapture Portal (Nginx)"]
+        portal -->|Embed Iframe| graf
+    end
+```
+
+## 2. Infrastructure Configuration
+
+### Prometheus Configuration (ansible/prometheus.yml)
+
+Defines the VM targets that Prometheus should scrape:
+
+```yaml
+global:
+    scrape_interval: 15s
+    evaluation_interval: 15s
+
+scrape_configs:
+    - job_name: 'homelab-nodes'
+      static_configs:
+        - targets:
+            - '172.30.1.100:9100' # freeipa
+            - '172.30.1.200:9100' # ansible-control
+            - '172.30.1.201:9100' # web-portfolio
+            - '172.30.1.202:9100' # media-stream
+```
+
+### Container Directory Permissions
+
+For security, the database containers run as non-root users inside Podman. Host directories must be assigned to their respective container UIS:
+
+*   **Prometheus (UID 65534 - nobody):** /var/lib/prometheus
+*   **Grafana (UID 472 - grafana):** /var/lib/grafana
+
+## 3. Web Dashboard Integration (Iframe Embedding)
+
+To embed live charts on the public portal wihout requiring visitors to log in:
+
+1. **Anonymous Access:** Enabled via the environment variables `GF_AUTH_ANONYMOUS_ENABLED=true` and `GF_AUTH_ANONYMOUS_ORG_ROLE=Viewer` in the Grafana container config.
+2. **Frame Permissions:** Enabled via `GF_SECURITY_ALLOW_EMBEDDING=true` to prevent browser clickjacking blocks.
+3. **Rolling Time-frames:** Appended `&from=now-5m&to=now` to the embed URLs to keep the charts scrolling in real-time.
+
+```html
+<iframe src="<Link>" class="telemetry-iframe" frameborder="0"></iframe>
+```
+
+## 4. Security & Remote Access
+
+To protect the metrics panel while keeping them accessible:
+
+1.  **Cloudflare Tunnel Routing:** The existing tunnel agent on media-stream is configured to route https://grafana.shooey.xyz to http://172.30.1.200:3001.
+2.  **Zero Trust Access:** Protected using Cloudflare Access. Only authenticated emails receive the secure cookie required to load the Grafana subdomains, hiding internal metrics from the public.
