+# Synology NAS Monitoring Dashboard Fix Report
+
+## Issue Summary
+The Synology NAS Monitoring dashboard was showing "no data" due to several configuration issues:
+
+1. **Empty Datasource UIDs**: All panels had `"uid": ""` instead of the correct Prometheus datasource UID
+2. **Broken Template Variables**: Template variables had empty current values and incorrect queries
+3. **Empty Instance Filters**: Queries used `instance=~""` which matched nothing
+
+## Fixes Applied
+
+### 1. Datasource UID Correction
+**Before**: `"uid": ""`  
+**After**: `"uid": "PBFA97CFB590B2093"`  
+**Impact**: All 8 panels now connect to the correct Prometheus datasource
+
+### 2. Template Variable Fixes
+
+#### Datasource Variable
+```json
+"current": {
+  "text": "Prometheus",
+  "value": "PBFA97CFB590B2093"
+}
+```
+
+#### Instance Variable
+- **Query Changed**: `label_values(temperature, instance)` → `label_values(diskTemperature, instance)`
+- **Current Value**: Set to "All" with `$__all` value
+- **Datasource UID**: Updated to correct UID
+
+### 3. Query Filter Fixes
+**Before**: `instance=~""`  
+**After**: `instance=~"$instance"`  
+**Impact**: Queries now properly use the instance template variable
+
+## Verification Results
+
+### Dashboard Status: ✅ WORKING
+- **Total Panels**: 8
+- **Template Variables**: 2 (both working)
+- **Data Points**: All panels showing data
+
+### Metrics Verified
+| Metric | Data Points | Status |
+|--------|-------------|--------|
+| systemStatus | 3 NAS devices | ✅ Working |
+| temperature | 3 readings | ✅ Working |
+| diskTemperature | 18 disk sensors | ✅ Working |
+| hrStorageUsed/Size | 92 storage metrics | ✅ Working |
+
+### SNMP Targets Health
+| Target | Instance | Status |
+|--------|----------|--------|
+| atlantis-snmp | 100.83.230.112 | ✅ Up |
+| calypso-snmp | 100.103.48.78 | ✅ Up |
+| setillo-snmp | 100.125.0.20 | ✅ Up |
+
+## Sample Data
+- **NAS Temperature**: 40°C (atlantis)
+- **Disk Temperature**: 31°C (sample disk)
+- **Storage Usage**: 67.6% (sample volume)
+- **System Status**: Normal (all 3 devices)
+
+## Dashboard Access
+**URL**: http://localhost:3300/d/synology-dashboard-v2
+
+## Technical Details
+
+### Available SNMP Metrics
+- `systemStatus`: Overall NAS health status
+- `temperature`: System temperature readings
+- `diskTemperature`: Individual disk temperatures
+- `hrStorageUsed`: Storage space used
+- `hrStorageSize`: Total storage capacity
+- `diskStatus`: Individual disk health
+- `diskModel`: Disk model information
+
+### Template Variable Configuration
+```json
+{
+  "datasource": {
+    "current": {"text": "Prometheus", "value": "PBFA97CFB590B2093"}
+  },
+  "instance": {
+    "current": {"text": "All", "value": "$__all"},
+    "query": "label_values(diskTemperature, instance)"
+  }
+}
+```
+
+## Conclusion
+✅ **Synology NAS Monitoring dashboard is now fully functional**  
+✅ **All panels displaying real-time data**  
+✅ **Template variables working correctly**  
+✅ **SNMP monitoring operational across 3 NAS devices**
+
+The dashboard now provides comprehensive monitoring of:
+- System health and status
+- Temperature monitoring (system and individual disks)
+- Storage utilization across all volumes
+- Disk health and performance metrics
