+# Grafana Dashboard Verification Report
+
+## Executive Summary
+✅ **All dashboard sections are now working correctly**  
+✅ **Datasource UID mismatches resolved**  
+✅ **Template variables configured with correct default values**  
+✅ **All key metrics displaying data**
+
+## Issues Resolved
+
+### 1. Datasource UID Mismatch
+- **Problem**: Dashboard JSON files contained hardcoded UID `cfbskvs8upds0b`
+- **Actual UID**: `PBFA97CFB590B2093`
+- **Solution**: Updated all dashboard files with correct datasource UID
+- **Files Fixed**: 
+  - infrastructure-overview.json
+  - node-details.json
+  - node-exporter-full.json
+  - synology-nas-monitoring.json
+
+### 2. Template Variable Default Values
+- **Problem**: Template variables had incorrect default values (e.g., `node_exporter`, `homelab-vm`)
+- **Solution**: Updated defaults to match actual job names and instances
+- **Updates Made**:
+  - Job: `node_exporter` → `atlantis-node`
+  - Nodename: `homelab` → `atlantis`
+  - Instance: `homelab-vm` → `100.83.230.112:9100`
+

+
+## Dashboard Access URLs
+
+- **Node Exporter Full**: http://localhost:3300/d/rYdddlPWk
+- **Synology NAS**: http://localhost:3300/d/synology-dashboard-v2
+- **Node Details**: http://localhost:3300/d/node-details-v2
+- **Infrastructure Overview**: http://localhost:3300/d/infrastructure-overview-v2
+
+## Technical Details
+
+### Prometheus Configuration
+- **Endpoint**: http://prometheus:9090
+- **Datasource UID**: PBFA97CFB590B2093
+- **Status**: ✅ Healthy
+- **Targets**: 15 total (13 up, 2 down)
+
+### GitOps Implementation
+- **Repository**: /home/homelab/docker/monitoring
+- **Provisioning**: Automated via Grafana provisioning
+- **Dashboards**: Auto-loaded from `/grafana/dashboards/`
+- **Datasources**: Auto-configured from `/grafana/provisioning/datasources/`
+
+## Verification Scripts
+
+Two verification scripts have been created:
+
+1. **fix-datasource-uids.sh**: Automated UID correction script
+2. **verify-dashboard-sections.sh**: Comprehensive dashboard testing script
+
+## Recommendations
+
+1. **Monitor Down Targets**: Investigate the 2 down targets:
+   - raspberry-pis: 100.123.246.75:9100
+   - vmi2076105-node: 100.99.156.20:9100
+
+2. **Regular Health Checks**: Run `verify-dashboard-sections.sh` periodically to ensure continued functionality
+
+3. **Template Variable Optimization**: Consider setting up more dynamic defaults based on available targets
+
+## Conclusion
+
+✅ **All dashboard sections are now fully functional**  
+✅ **Data is displaying correctly across all panels**  
+✅ **Template variables are working as expected**  
+✅ **GitOps implementation is successful**
+
+The Grafana monitoring setup is now complete and operational with all major dashboard sections verified and working correctly.
