How do you monitor system resources (CPU, memory, disk) using Python?

Use psutil for comprehensive system monitoring. It provides cross-platform system information essential for automation monitoring.

import psutil

def get_system_info():
    return {
        'cpu_percent': psutil.cpu_percent(interval=1),
        'memory': psutil.virtual_memory()._asdict(),
        'disk': psutil.disk_usage('/')._asdict(),
        'network': psutil.net_io_counters()._asdict()
    }

# Monitor with thresholds
def check_system_health():
    cpu = psutil.cpu_percent(interval=1)
    memory = psutil.virtual_memory().percent
    
    alerts = []
    if cpu > 80:
        alerts.append(f"High CPU usage: {cpu}%")
    if memory > 85:
        alerts.append(f"High memory usage: {memory}%")
    
    return alerts
