Code Example: Simple Network Monitoring Script

Here’s a basic Python script that demonstrates how you might monitor network connectivity to multiple hosts:

import subprocess
import time

def ping(host):
    param = '-n' if subprocess.sys.platform.lower()=='win32' else '-c'
    command = ['ping', param, '1', host]
    return subprocess.call(command) == 0

def monitor_network(hosts, interval=60):
    while True:
        for host in hosts:
            result = ping(host)
            print(f"{time.ctime()} - {host} is {'up' if result else 'down'}")
        time.sleep(interval)

if __name__ == "__main__":
    hosts_to_monitor = ['8.8.8.8', 'google.com', 'amazon.com']
    monitor_network(hosts_to_monitor)

This script periodically pings a list of hosts and reports their status. It’s a simple example of how network monitoring can be automated, which is crucial for maintaining complex network infrastructures.
