lp-mu-ethernet-monitor.py
Python script using psutil to monitor network throughput in real-time.
Install python3-psutil. Identify the exact Ethernet interface name (e.g., enp1s0) using 'ip addr'. This script displays cumulative sent/received bytes, useful for verifying the stability of the 2.5 Gbps link.
