# 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`

- ✅ alertmanager: alertmanager:9093

## 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.
