This guide introduces five essential Linux command‑line utilities—nethogs, nload, cbm, iftop, and iPerf—explaining their focus areas, key features, and example commands for monitoring process‑level bandwidth, interface traffic, host connections, and conducting network performance tests across multiple machines.
This article introduces five open‑source Linux utilities—nethogs, nload, cbm, iftop, and iPerf—explaining their focus, usage commands, and how they help monitor network traffic at process, interface, and host levels while testing network performance.
Learn how to monitor and test network performance in Linux using five powerful command‑line utilities—nethogs for per‑process bandwidth, nload for real‑time traffic graphs, cbm for colorful interface, iftop for host‑level connections, and iPerf for detailed throughput measurements.
This guide explains how to choose appropriate server hardware, analyze CPU, memory, disk I/O and network load, and fine‑tune kernel parameters such as file limits and TCP settings to achieve reliable high‑concurrency performance.
This guide shows how to install and use nload, iftop, and sar for live network bandwidth monitoring on Linux, explains their key parameters, and provides two shell scripts that calculate per‑second inbound and outbound traffic from /proc/net/dev.
This guide shows how to install and use nload, iftop, and sar for real‑time network traffic monitoring on Linux, explains each tool's key parameters, and provides two custom shell scripts that calculate per‑second inbound and outbound traffic using /proc/net/dev.
