Adds ComfyUI-NVML-Monitor to the registry.
What it does: NVIDIA-first hardware telemetry node. Adds a draggable floating chip in ComfyUI showing CPU%, RAM, VRAM, and GPU utilization, plus a click-to-expand popup with detailed GPU stats (utilization, temperature, power draw vs limit, clocks, fan, processes) and a System tab (per-core CPU mini-bars, RAM, driver).
Why another monitor: existing options like ComfyUI-ADLX-Monitor (AMD/Windows) and ComfyUI-XPUSYS-Monitor (cross-vendor) target different use cases. This one is built specifically for NVIDIA + Linux, often running inside Docker. It uses
pynvml/nvidia-ml-pydirectly and includes explicit accounting for VRAM held by external containers/host processes that NVML inside a container cannot attribute to a visible PID — surfaced as a clear "External (other containers / host)" row in the popup's process table.Implementation:
