Docker Monitoring Stack

This directory contains the fixed Grafana monitoring stack with working dashboards and proper datasource configurations.

🔧 Recent Fixes

• Fixed datasource UIDs: All dashboards now use correct Prometheus UID (PBFA97CFB590B2093)
• Fixed template variables: Proper current values and working queries
• Fixed instance filters: Corrected empty instance filters (instance=~"" → instance=~"$instance")
• Verified functionality: All dashboard panels now display real-time data

📊 Dashboards

1. Synology NAS Monitoring (synology-nas-monitoring.json) - 8 panels, SNMP metrics
2. Node Exporter Full (node-exporter-full.json) - 32 panels, comprehensive system monitoring
3. Node Details (node-details.json) - 21 panels, detailed node metrics
4. Infrastructure Overview (infrastructure-overview.json) - 7 panels, system overview

🚀 Deployment

cd docker/monitoring
docker-compose up -d

🔍 Verification
