# 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`
|
|
|
|

|
### 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
|
|
|
|

✅ **All dashboard sections are now fully functional**
|
|
✅ **Data is displaying correctly across all panels**
|
|
✅ **Template variables are working as expected**
|
