Glances
Glances is a cross-platform, real-time system monitoring tool that provides a comprehensive overview of system resources in a terminal-based interface. It displays key metrics such as CPU, memory, disk I/O, network usage, and process information in a user-friendly, color-coded format. It is designed for quick diagnostics and performance analysis on servers, desktops, and embedded systems.
Developers should use Glances when they need a lightweight, command-line tool to monitor system performance in real-time, especially for troubleshooting, optimizing resource usage, or managing servers without a GUI. It is particularly useful in DevOps and sysadmin scenarios for checking load, identifying bottlenecks, or monitoring remote systems via its client-server mode.
