The collector monitors AMD GPUs directly from the Linux kernel’s sysfs and hwmon interfaces. No ROCm, no user-space libraries, and no additional drivers are needed beyond the standard AMDGPU kernel module.

​
Requirements

  • Linux with the amdgpu kernel driver
  • Kernel 5.x+ (sysfs/hwmon paths are stable from 5.x onwards)
