What methods do you know for monitoring network node status?

The following methods are often used to monitor the status of network nodes:

• Ping — checking node availability and measuring response time.

• SNMP (Simple Network Management Protocol) — collecting statistics and device status through specialized agents.

• Using logs and monitoring systems (e.g., Zabbix, Nagios, Prometheus) — for tracking metrics, alerts, and events.

• Traceroute — diagnosing the route to the node.

• Monitoring ports and services — checking that necessary services are running.

Example of a simple ping in Python:

import subprocess

def ping(host):
    result = subprocess.run(['ping', '-c', '1', host], stdout=subprocess.PIPE)
    return result.returncode == 0

print(ping('8.8.8.8'))  # True if the node is accessible

These methods help to promptly identify network issues and ensure stable operation.
