About:
bwm-ng is a lightweight, console-based network and disk I/O bandwidth monitor that provides real-time statistics.

Key Features:

Real-time monitoring for network, disk, and CPU interfaces
Minimal resource usage and no GUI dependencies
Supports CSV, XML, and JSON output for easy scripting
Configurable refresh rate and output format

Use Cases:

Troubleshooting network performance issues on headless servers
Monitoring disk I/O throughput in real-time during file operations
Automated bandwidth logging for capacity planning

Alternatives:

iftop – iftop focuses solely on network traffic by connection, while bwm-ng provides aggregate interface stats and disk I/O.
nload – nload offers a more visual graph for network usage, whereas bwm-ng provides a more compact, text-based view.
