End-to-end setup for monitoring NVMe SSD health using smartctl, Prometheus, and Grafana. Ideal for dedicated servers (Hetzner, OVH, etc).

This repository helps you:

• ✅ Check NVMe SSD health manually using smartctl
• ✅ Collect SMART metrics with Prometheus via smartctl_exporter
• ✅ Trigger alerts for early SSD failure detection
• ✅ Visualize health metrics in Grafana
• ✅ Replace disks before they die unexpectedly

• smartctl from smartmontools
• smartctl_exporter (Go-based Prometheus exporter)
• Prometheus
• Grafana

1. Install smartmontools

   sudo apt install smartmontools

2. Clone and build smartctl_exporter

   git clone https://github.com/prometheus-community/smartctl_exporter
   cd smartctl_exporter
   go build
   

3. Install the exporter binary

   sudo cp smartctl_exporter /usr/local/bin/
   

4. Use the systemd unit from systemd/ Enable it with:

   sudo systemctl daemon-reload
   sudo systemctl enable smartctl_exporter
   sudo systemctl start smartctl_exporter
   

5. Configure Prometheus

   • Add job config from prometheus/
   • Add alert rules from smartctl_alerts.yml to rule_files

6. Import Grafana dashboard

   • Use the file grafana/ssd_dashboard.json
