The collector monitors Intel GPUs via the Linux kernel’s sysfs, hwmon, and DRM interfaces exposed by the i915 and Xe drivers. No Intel GPU tools, no OneAPI, and no user-space libraries are required.
Intel GPU support provides thermal, power, energy, and clock metrics. Utilization and memory metrics are not available via the sysfs/hwmon interface — these would require the Intel XPU Manager or similar tooling.

​
Requirements

  • Linux with the i915 or xe kernel driver
  • Kernel 5.10+ for sysfs metric exposure
  • Kernel 6.16+ for fan speed (fan1_input)
