## 🔧 Technical Notes
|
|
|
|
### pve-router systemd Issue
|
|
The Proxmox host (pve-router) has dbus/systemd connectivity issues that cause the systemd collector to hang. This is likely due to it being a lightweight Proxmox setup or container-based environment.
|
|
|
|
**Workaround:** Disabled systemd collector with `--no-collector.systemd`
|
|
|
|
**To make permanent:**
|
|
1. Create systemd service file: `/etc/systemd/system/prometheus-node-exporter.service`
|
|
2. Add `--no-collector.systemd` to ExecStart
|
|
3. Enable and start: `systemctl enable --now prometheus-node-exporter`
|
|
|
|
### vps-gaming Firewall
|
|
UFW is active on the OVH VPS. Port 9100 has been added to allowed ports.
|
|
|
|
**Current UFW Rules:**
|
|
- 22/tcp (SSH)
|
|
- 80/tcp, 443/tcp (HTTP/HTTPS)
|
|
- 51820/udp (WireGuard)
|
|
- 21117/tcp (Unknown service)
|
|
- 9100/tcp (node_exporter) ← NEW
|

|
## 🎯 Next Steps (Optional)
|
|
|
|
1. **Make pve-router persistent:**
|
|
- Create systemd service with --no-collector.systemd flag
|
|
- Ensure it starts on boot
|
|
|
|
2. **Monitor for 24 hours:**
|
|
- Verify no alerts fire
|
|
- Check Prometheus UI for any issues
|
|
|
|
3. **Consider additional exporters:**
|
|
- Proxmox VE exporter (VM/container metrics)
|
|
- Blackbox exporter (endpoint monitoring)
|
|
- Custom textfile collector (custom metrics)
|
|
