+## Dashboards
+
+| Dashboard | UID | Description |
+|-----------|-----|-------------|
+| Infrastructure Overview | `infrastructure-overview-v2` | Fleet status, CPU, Memory, Disk, Network for all hosts |
+| Node Details | `node-details-v2` | Per-REDACTED_APP_PASSWORD CPU breakdown, per-core usage, memory details, disk I/O |
+| Synology Monitoring | `synology-dashboard-v2` | Synology NAS CPU, Memory, Load, Uptime via SNMP |
+| Node Exporter Full | `rYdddlPWk` | Comprehensive node exporter metrics |
+
+## SNMP Configuration
+
+The `snmp_synology.yml` config is deployed to each Synology NAS at:
+- **Atlantis**: `/volume2/metadata/docker/snmp/snmp.yml`
+- **Calypso**: `/volume1/docker/snmp/snmp.yml`
+- **Setillo**: `/volume1/docker/snmp/snmp.yml`
+
+## Monitored Hosts
+
+### Node Exporter Targets
+- homelab-node (100.67.40.126:9100)
+- atlantis-node (100.83.230.112:9100)
+- calypso-node (100.103.48.78:9100)
+- setillo-node (100.125.0.20:9100)
+- concord-nuc-node (100.72.55.21:9100)
+- proxmox-node (100.87.12.28:9100)
+- truenas-node (100.75.252.64:9100)
+- raspberry-pis (100.77.151.40:9100)
+
+### SNMP Targets (Synology)
+- atlantis-snmp (100.83.230.112)
+- calypso-snmp (100.103.48.78)
+- setillo-snmp (100.125.0.20)
+
+## Deployment
+
+### Homelab VM (Main Stack)
+
+The main monitoring stack runs on Homelab VM:
+```bash
+cd ~/docker/monitoring
+
+# Using the compose file from this repo:
+docker-compose -f docker-compose.homelab-vm.yml up -d
+
+# Or if already deployed:
+docker-compose up -d
+```
+
+**Services:**
+- **Grafana**: http://homelab:3300 (admin / set via GF_SECURITY_ADMIN_PASSWORD)
+- **Prometheus**: http://homelab:9090
+- **Node Exporter**: Runs in host network mode on port 9100
+
+### Remote Hosts
+
+Each remote host runs node-exporter and/or snmp-exporter as specified in the `docker-compose/` folder.
