What is Zenith?
Zenith is a terminal-based graphical system monitoring tool for *nix systems, written in Rust. It provides a comprehensive overview of system performance, similar to 'top' or 'htop', but with enhanced features like zoom-able charts for CPU, Memory, Network, and Disk usage. Users can quickly glance at disk free space, network interface IP addresses, and CPU frequency. It also highlights top users of CPU, Memory, and Disk, and displays battery information.
This tool is ideal for developers, system administrators, and anyone who needs detailed, real-time insights into their Linux or macOS system's performance. Its interactive process table allows filtering and includes per-process disk usage, with the ability to change process priority and manage processes using signals. Zenith also offers performance data persistence between runs and GPU utilization metrics for NVIDIA GPUs, making it a powerful utility for system diagnostics and optimization.

How does Zenith handle process management beyond displaying information?
Zenith allows for managing processes by sending signals, similar to
top or htop. This enables users to interact with and control running processes directly from the Zenith interface.Which Linux distributions are officially supported for Zenith's pre-compiled `.deb` packages?
Zenith provides pre-compiled 64-bit
.deb packages for Debian-based Linux distributions. These packages require Debian version 9 or newer, or Ubuntu version 16.04 or newer.Can Zenith display disk usage per process, and is there a filter for the process table?
Yes, Zenith's top-like process table includes per-process disk usage. The process table is also filterable, allowing users to quickly find and monitor specific processes.
What are the minimum requirements for building Zenith from source, specifically regarding Rust and Clang?
Building Zenith from source requires Rust version 1.40 or newer and the
libclang development packages. For Ubuntu/Debian, libclang-dev is needed, while CentOS/RHL/Fedora require clang.Source: github.com
