This article introduces several powerful Linux command‑line monitoring utilities—including htop, atop, nmon, vtop, bashtop, gtop, and glances—explaining their features, installation commands, and key interactive shortcuts for tracking CPU, memory, disk, and network usage.
This guide introduces several interactive command‑line utilities—htop, atop, nmon, vtop, bashtop, gtop and glances—explaining their features, key shortcuts, and installation steps so Linux administrators can monitor CPU, memory, disk and network usage more effectively than with the classic top command.
Discover five powerful Linux system‑monitoring alternatives to htop—atop, vtop, btop++, Glances, and nmon—each with unique features, visual styles, and straightforward installation commands for popular distributions.
This guide introduces several Linux performance monitoring tools—nmon, perf, top, iostat, sar, dstat, and htop—explaining their functions, key metrics, and installation commands for use on a Huawei Kunpeng server. It also shows how to generate flame graphs with perf and highlights htop's interactive advantages.
This guide shows how to download, extract, and run the lightweight nmon performance monitoring tool on CentOS 7, including the exact commands to fetch the package, choose the correct binary, start the utility, and view CPU and memory statistics using interactive keys.
This guide explains how to use Linux built‑in tools (iostat, iotop, sar, dstat) and popular monitoring solutions (nmon, Zabbix, Cacti) to collect, interpret, and visualize disk I/O metrics such as throughput, latency, and utilization for performance troubleshooting.
This article outlines a comprehensive performance testing workflow, introduces layered and segment diagnostic methods, presents a detailed Apache/Tomcat/Linux/Oracle case study with LoadRunner and Nmon, and discusses monitoring metrics, analysis results, and practical recommendations for optimizing system performance.
nmon is a lightweight Linux tool that collects and displays real‑time CPU, memory, disk, and network metrics on a single screen, offers background data collection with customizable intervals, and generates analysis files that can be visualized using nmon_analyser for detailed performance reporting.
