Zenith is a terminal UI for monitoring system resources built in Rust, delivering real-time insights into your system's performance directly in your terminal.

Key capabilities include:

Resource visualization with optional CPU, memory, network, and disk usage charts
Quick system overview showing disk free space, network interface IPs, and CPU frequency
Process management with a filterable top-like table that tracks per-process disk usage, CPU, and memory consumption
Interactive charts that you can zoom and scroll through to review historical performance data
GPU support for NVIDIA GPUs with per-process utilization metrics
Battery monitoring displaying percentage, charge/discharge time, and power consumption
Process control including priority adjustment and signal management
Performance persistence that saves metrics between sessions
Advanced Linux features like delay accounting when running with root permissions

The tool provides detailed insights into top resource consumers across CPU, memory, and disk, helping you quickly identify performance bottlenecks. Disk free space charts and comprehensive metrics make capacity planning straightforward. Currently available for Linux and macOS, with planned support for BSD variants.
