Minisforum MS-01 — enabling voltage and fan metrics (Nuvoton NCT6798D)
By default, on Proxmox kernel 6.8.12-15-pve, only CPU/NVMe temperatures are available. sensors-detect —auto finds only coretemp, no Super I/O support. The hardware (Nuvoton NCT6798D) requires the NCT6775 driver, which is not included in this kernel build.
Driver patching and installation
- Install build tools and kernel headers
sudo apt update
sudo apt install build-essential
sudo apt install proxmox-headers-$(uname -r)Preparing to unpack .../proxmox-headers-6.8.12-15-pve_6.8.12-15_amd64.deb ...
Unpacking proxmox-headers-6.8.12-15-pve (6.8.12-15) ...
Setting up proxmox-headers-6.8.12-15-pve (6.8.12-15) ...- Download the NCT6775 driver
⚠️ Do not use the abandoned killghost fork.
Instead, use the damix1/nct6775 repo, which can be patched for newer chips.
git clone https://github.com/damix1/nct6775.git /root/nct6775
cd /root/nct6775- Patch for Nuvoton NCT6798D support
Edit nct6775.c. Extend the enum:
enum kinds { nct6106, nct6775, nct6776, nct6779,
nct6791, nct6792, nct6793, nct6795,
nct6796, nct6798 };Add names:
static const char * const nct6775_device_names[] = {
"nct6106", "nct6775", "nct6776", "nct6779",
"nct6791", "nct6792", "nct6793", "nct6795",
"nct6796", "nct6798",
};
static const char * const nct6775_sio_names[] __initconst = {
"NCT6106D", "NCT6775F", "NCT6776D/F", "NCT6779D",
"NCT6791D", "NCT6792D", "NCT6793D", "NCT6795D",
"NCT6796D", "NCT6798D",
};Add detection case:
switch (val & SIO_ID_MASK) {
...
case 0xd42: /* NCT6798D */
sio_data->kind = nct6798;
break;
}This minimal patch makes the driver recognize NCT6798D.

Node Exporter (should be runned with —collector.hwmon) will expose new metrics as:
node_hwmon_in_volts{chip="nct6798-isa-0a20",sensor="in1"}
node_hwmon_fan_rpm{chip="nct6798-isa-0a20",sensor="fan1"}Grafana hwmon dashboard should catch these metrics automatically.

для дебага WMI — он позволяет просматривать классы, пространства имен, методы. Тулза довольно старая, на сайте MS её уже не найти (раньше поставлялась в составе WMI SDK).
поспешили навесить ярлык «deprecated» на свою старую недоделку Web Transaction Recorder, хотя новый рекордер совершенно не готов к использованию в проде и покрывает только элементарные юзкейсы.
