🖥️ Info 'n Stat — Web-Based Performance Profiler for Unix-like Systems

Info 'n Stat is a responsive, web-based performance profiling dashboard tailored for Unix-like systems — especially servers. It provides real-time system statistics, service management tools, and powerful logging utilities, all accessible from a clean, Bootstrap-powered interface.

🧰 System Requirements

Ensure the following system packages are installed on your Unix-like system:

• sysstat — for pidstat
• nodejs — to run the backend
• npm — to install nodejs packages
• express — the backend router
• semver — to verify local version

On Debian/Ubuntu:

sudo apt update && sudo apt install -y curl sysstat && curl -fsSL https://deb.nodesource.com/setup_lts.x | sudo -E bash - && sudo apt install -y nodejs && npm install express semver

On Arch:

sudo pacman -Sy --noconfirm sysstat nodejs npm && npm install express semver

On Fedora:

sudo dnf install -y sysstat nodejs npm && npm install express semver
