Python Script to Monitor Network Traffic

To monitor network traffic in Python, you can use the psutil library, which provides a convenient interface to retrieve information on system utilization, including network-related data.

Here’s a simple example of a Python script that monitors network traffic:

import psutil
import time

def get_network_usage(interval=1):
    while True:
            net_stats = psutil.net_io_counters()
            bytes_sent = net_stats.bytes_sent
            bytes_received = net_stats.bytes_recv

            print(f"Bytes Sent: {bytes_sent} B")
            print(f"Bytes Received: {bytes_received} B")


        except KeyboardInterrupt:
            print("\nMonitoring stopped.")

if __name__ == "__main__":

In this script:

  • psutil.net_io_counters() retrieves network I/O statistics.
  • bytes_sent represents the total number of bytes sent over the network.
  • bytes_received represents the total number of bytes received over the network.

The script prints these values in a loop with a specified interval (default is 1 second). You can adjust the interval parameter to control how frequently the network statistics are printed.

To run this script, you need to install the psutil library:

pip install psutil

For more advanced network monitoring and analysis, consider exploring tools and libraries specifically designed for this purpose. This script provides a basic example.
