b-top (short for bad-top) is a terminal-based, Rust-powered system resource viewer for UNIX-like systems. Inspired by tools like bashtop and htop, b-top provides a visually impressive process monitoring and management tool with shader-like implementations by using TachyonFX.
- Per-Core CPU Usage: Real-time usage display for each CPU core with color-coded indicators.
- CPU Usage Graph: Sparkline graph showing historical average CPU usage.
- Memory Monitoring: Visual gauge showing used vs. total memory in GB.
- Network Stats: Displays RX/TX bytes for interfaces like
eth0andlo. - Process Table: Sortable list of top processes by CPU, memory, or network usage (WIP).
- Smooth Animations: Powered by
tachyonfxfor subtle UI transitions. - Keyboard Navigation: Scroll, jump, sort, and switch interfaces with intuitive keybindings.
- Disk Usage: Track disk usage with a visual gauge and switch between disks for active monitoring.
- Tree View: See parent and child processes for each running/sleeping process.
