AMD Monitor - Unified GPU Monitoring
|
|
=====================================
|
|
Auto-detects best available backend:
|
|
1. LibreHardwareMonitor (Temperature, Fan, Load, Clocks, Power)
|
|
2. ADL (AMD Display Library)
|
|
3. PowerShell Counters (Utilization, VRAM, GPU name)
|
|
4. psutil (System RAM fallback)
|
|
|
|
Usage:
|
|
from monitor import get_amd_monitor
|
|
monitor = get_amd_monitor()
|
|
stats = monitor.get_gpu_stats(0)
|
|
print(stats.gpu_name, stats.utilization_gpu, stats.temperature)
