Next-Generation Linux System Monitor
Elegant TUI · Real-time Monitoring · Process Management · Future-proof Architecture
Version 3.1.0 Stellar | Built with Rust 🦀
Lyvoxa is a professional-grade system monitoring tool for Linux, combining elegance with performance. Built from the ground up in Rust, it delivers an intuitive Terminal User Interface (TUI) with advanced features for modern system administration.
- Complete process table with all columns found in traditional system monitors: NI, PRI, PID, USER, COMMAND, TIME, MEM, CPU%, VIRT, RES, SHR, S
- Interactive process control - adjust nice values, kill processes
- Real-time filtering and search with live updates
- Multiple sort modes - CPU, memory, PID, user, command
- Process selection with arrow key navigation
- Per-core CPU monitoring with individual gauges for all CPU cores
- Memory usage tracking with detailed statistics and visual gauges
- Network I/O monitoring with RX/TX bytes per second
- Historical charts for CPU, memory, and network with 120-point rolling history
- Live system metrics updated every second
- Three elite themes: Dark (professional), Stellar (space/neon), Matrix (green cyber)
- Runtime theme switching with Tab key hotkey
- Consistent color schemes across all UI elements
- Futuristic visual design with smooth transitions
- F1: Help overlay with all shortcuts
- F2: Setup and configuration
- F3: Live search processes
- F4: Filter processes
- F5: Charts toggle (on/off)
- F6: Cycle sort modes
- F7/F8: Adjust process priority (nice)
- F9: Kill selected process
- F10: Quit application
