How do I get sm occupancy?

like nvidia-smi pmon

SM occupancy and per-process GPU utilization (as reported by nvidia-smi pmon) are not currently available in jetson_stats. This is a platform limitation:

Traditional Jetsons (Nano through Orin): The integrated GPU only exposes an aggregate load percentage via sysfs (/sys/class/devfreq/.../device/load). There is no kernel interface for per-SM or per-process GPU compute utilization.
Thor (JetPack 7+): While NVML is available, the Jetson NVML implementation does not support nvmlDeviceGetProcessUtilization or similar per-process compute APIs.
What is available today:

Overall GPU utilization (jtop.gpu[name]['status']['load']) -- aggregate % across all SMs
Per-process GPU memory -- via NVMap (/sys/kernel/debug/nvmap/iovmm/maps)
GPU frequencies including per-GPC clocks where supported
If NVIDIA adds per-process GPU utilization support to the Jetson kernel or NVML in a future JetPack release, we could integrate it. For now, this isn't something jetson_stats can provide.
