Nethogs vs Termshark

Nethogs — Nethogs is a Linux tool that provides real-time network traffic usage by process. It shows bandwidth usage on a per-process basis in an easy to understand format.

Termshark — Termshark is a terminal based network protocol analyzer. It allows you to inspect network traffic and analyze packets, similar to Wireshark, but runs in a terminal instead of a graphical interface.

Nethogs offers Monitors bandwidth usage per process in real time, Displays network usage in a terminal using a text-based user interface, Shows program name, PID, sent/received data, and total usage, Can filter processes by name or PID, Lightweight and non-intrusive, while Termshark provides Captures live packet data from network interfaces, Displays packets in a terminal user interface, Filters packets using display filters, Analyzes protocols including TCP, UDP, HTTP, DNS, and more, Supports common capture file formats like PCAP and PCAPNG.

Nethogs stands out for Easy to use and understand, Provides granular visibility into bandwidth usage, Helpful for identifying and troubleshooting network hogs; Termshark is known for Lightweight terminal-based interface, No GUI overhead or dependencies, Works over SSH connections.
