hitome

hitome is a quick and dirty system monitor that aims to be light on system resources. Think of it as a lighter, less featureful version of glances or htop.

hitome only targets Linux as it parses non-portable data from /proc.

Released under the Apache License, version 2.0.

Features

• Monitors memory usage,
• Swap/Zram usage,
• System pressure information (CPU/Mem/IO),
• Usage of each CPU core,
• Traffic to/from block devices and network interfaces,
• Hardware temperatures (as reported by the hwmon or nvml interfaces),
• Filesystem usage,
• Tasks (processes) status and CPU utilisation.

This is not meant to be a full-blown top/htop replacement, use these tools instead if you want more features.

Usage

% hitome --help
Usage: hitome [-c <colour>] [--columns <columns>] [--rows <rows>] [-w <column-width>] [-i <refresh-interval>]

A very simple, non-interactive system monitor

Options:
  -c, --colour      true/false: use colour and other fancy escape sequences
                    (defaults to guessing based on $TERM)
  --columns         width of the terminal window, in characters (if omitted,
                    guess)
  --rows            height of the terminal window, in lines (if omitted, guess)
  -w, --column-width
                    the width of columns, in characters
  -i, --refresh-interval
                    refresh interval in milliseconds
  --help            display usage information

Dependencies

• Linux kernel
• A rust toolchain (only for building)
• NVML (optional; only for querying state of NVIDIA GPUs)
