}

Per-GPU metrics sourced from all-smi (NVIDIA NVML / AMD / TPU / …). Populated only when a supported GPU library is detected at runtime; an empty Vec means no GPUs are present or no driver is installed.

Fields

uuid: String

Vendor-assigned device UUID (stable across reboots for physical GPUs).

name: String

Human-readable device name, e.g. “NVIDIA GeForce RTX 4090”.

device_type: String

Device class reported by all-smi: “GPU”, “NPU”, “TPU”, etc. Equivalent to the “kind” of accelerator.

host_id: String

Host-level device identifier (slot, bus address, or platform index).

detail: HashMap<String, String>

Additional platform-specific identity fields keyed by the driver. For NVIDIA these typically include PCI device/vendor IDs and the driver version; for AMD, the ASIC name and PCIe topology; for TPU, the chip revision. Keys and values vary by vendor.

utilization_pct: f64

Core utilisation (0.0–100.0).

vram_total_bytes: u64

Total VRAM in bytes.

vram_used_bytes: u64

Used VRAM in bytes.

vram_used_pct: f64

Fraction of VRAM in use (0.0–100.0).

temperature_celsius: u32

Die temperature in degrees Celsius.

power_watts: f64

Power draw in watts.

frequency_mhz: u32

Core clock frequency in MHz.

core_count: Option<u32>

Number of shader/compute cores, if reported by the driver.
