Terminal-based CPU stress and monitoring utility

Quick Overview

Bottom is a customizable cross-platform graphical process/system monitor for the terminal, similar to htop. It provides real-time information about CPU, memory, disk, network, and processes, with a clean and intuitive interface. Bottom is written in Rust and aims to be both performant and feature-rich.

Pros

Cross-platform support (Linux, macOS, Windows)
Highly customizable with themes and layout options
Lightweight and efficient, with low resource usage
Actively maintained and regularly updated

Cons

Steeper learning curve compared to simpler alternatives like htop
May require additional configuration for optimal use
Limited support for some advanced features on certain platforms
Relatively new project, so it may have fewer community resources compared to more established tools

Getting Started

To install Bottom, you can use one of the following methods:

Using Cargo (Rust's package manager):
```
cargo install bottom
```
On macOS using Homebrew:
```
brew install bottom
```
On Windows using Scoop:
```
scoop install bottom
```

After installation, simply run btm in your terminal to launch Bottom. You can customize the layout and appearance by creating a configuration file at ~/.config/bottom/bottom.toml (Unix-like systems) or %AppData%\bottom\bottom.toml (Windows).

For more detailed information on usage and configuration, refer to the project's documentation on GitHub.

Competitor Comparisons

btop

20,379

A monitor of resources

Pros of btop

Written in C++, potentially offering better performance
More customizable interface with themes and layout options
Supports a wider range of system information displays (e.g., detailed network stats)

Cons of btop

Less cross-platform compatibility (primarily Linux-focused)
Steeper learning curve due to more complex configuration options
Larger binary size and potentially higher resource usage

Code Comparison

btop (C++):

void Cpu::draw(const bool force) {
    if (force or should_draw) {
        auto& cpu_box = boxes.at("cpu");
        if (cpu_box.getHeight() < 1) return;
        cpu_box.clear();
        // ... (drawing logic)
    }
}

bottom (Rust):

pub fn draw_cpu(&mut self, f: &mut Frame<B>, area: Rect, force_redraw: bool) -> Result<()> {
    if !self.should_draw && !force_redraw {
        return Ok(());
    }
    // ... (drawing logic)
}

Both projects implement similar functionality for drawing CPU information, but btop uses C++ while bottom uses Rust. The btop implementation appears to have more direct control over the drawing process, while bottom's approach seems more abstracted and potentially safer due to Rust's memory safety features.

glances

26,585

Glances an Eye on your system. A top/htop alternative for GNU/Linux, BSD, Mac OS and Windows operating systems.

Pros of Glances

More comprehensive system monitoring, including network, disk I/O, and processes
Cross-platform support (Linux, macOS, Windows)
Web-based interface option for remote monitoring

Cons of Glances

Higher resource usage due to more extensive monitoring features
Less customizable interface compared to Bottom's widget-based approach

Code Comparison

Glances (Python):

from glances_api import GlancesApi

glances = GlancesApi(host='localhost', port=61208)
cpu_percent = glances.getCpu()['total']
print(f"CPU usage: {cpu_percent}%")

Bottom (Rust):

use bottom::data::CpuData;

let cpu_data = CpuData::new();
let cpu_percent = cpu_data.get_cpu_usage_percent();
println!("CPU usage: {}%", cpu_percent);

Summary

Glances offers a more comprehensive monitoring solution with cross-platform support and a web interface, making it suitable for remote monitoring and users who need detailed system information. However, it may consume more resources and has a less customizable interface.

Bottom, on the other hand, provides a lightweight and customizable terminal-based interface with a focus on performance. It's ideal for users who prefer a minimalist approach and want to tailor their monitoring experience.

The choice between the two depends on the specific monitoring needs, desired features, and performance considerations of the user.

htop

htop - an interactive process viewer

Pros of htop

More mature and widely adopted project with a longer history
Supports a broader range of Unix-like systems, including Linux, FreeBSD, and macOS
Offers more detailed process information and advanced sorting options

Cons of htop

Less visually appealing interface compared to bottom's modern design
Limited customization options for the UI layout and colors
Slower development cycle and less frequent updates

Code Comparison

htop (C):

void Process_writeCommand(Process* this, int writeComm) {
   if (this->comm && (Process_isThread(this) || writeComm)) {
      char* comm = this->comm;
      if (Process_isKernelThread(this)) {
         comm++;
      }
      xSnprintf(buffer, n, "%s", comm);
   } else {
      xSnprintf(buffer, n, "%s", this->cmdline[0]);
   }
}

bottom (Rust):

pub fn get_command(&self) -> String {
    if let Some(cmd) = &self.command {
        cmd.to_string()
    } else {
        self.name.clone()
    }
}

The code snippets show different approaches to retrieving process command information. htop uses C and handles various conditions, while bottom uses Rust with a more concise implementation.

Code Comparison

ytop (Rust):

pub fn get_cpu_usage() -> f64 {
    let cpu = sys_info::cpu_num().unwrap();
    let load = sys_info::loadavg().unwrap();
    load.one / cpu as f64 * 100.0
}

bottom (Rust):

pub fn get_cpu_usage_percent(
    cpu: &Cpu,
    prev_idle: &mut u64,
    prev_non_idle: &mut u64,
) -> f64 {
    let (idle, non_idle) = cpu.get_cpu_times();
    let delta_idle = idle - *prev_idle;
    let delta_non_idle = non_idle - *prev_non_idle;
    let delta_total = delta_idle + delta_non_idle;

    *prev_idle = idle;
    *prev_non_idle = non_idle;

    if delta_total == 0 {
        0.0
    } else {
        (delta_non_idle as f64 / delta_total as f64) * 100.0
    }
}

bottom offers a more detailed and accurate CPU usage calculation, while ytop provides a simpler implementation. This reflects the overall difference between the two projects, with bottom offering more advanced features and customization options, while ytop focuses on simplicity and ease of use.

Thanks

This project is very much inspired by gotop, gtop, and htop.
This application was written with many, many libraries, and built on the work of many talented people. This application would be impossible without their work. I used to thank them all individually but the list got too large...
And of course, another round of thanks to all the contributors and package maintainers!
