Sysit

System Sit, check on the system with a quick glance!

Crate Build

About

System resources overview within 50 characters. Relies on sysinfo to get all the relevant system information.

sysit with tmux

Install

If you are on Arch, install via Aur: https://aur.archlinux.org/packages/sysit-bin/

On other platforms, you can use the install script, which will install a pre-built binary. To install at /usr/local/bin/:

curl -s https://raw.githubusercontent.com/crodjer/sysit/main/scripts/install.sh | sudo bash

Or, to install at a location of your choice, say ~/.local/bin:

curl -s https://raw.githubusercontent.com/crodjer/sysit/main/scripts/install.sh | bash -s ~/.local/bin

You can always use cargo if your platform isn't supported:

cargo install sysit

Reasoning

The ability to quickly see basic system information without needing a context switch can be useful. sysit is easy to incorporate in the various status bars - such as that of tmux, i3/sway etc.

Understanding the output

 Memory Usage
 CPU Information (usage and optionally frequency)
 Temperature for the hottest sensor
 Network Ping

Usage

From the console

Simply type sysit for a quick glance at the system information.

sysit on  main is 📦 v0.6.0 via 🦀 v1.56.1
at 18:43:42 ❯ sysit
 21%5%45°C    12.0 ms

This can also be used with a desktop manager's applets. For example, Xfce's genmon.

Continuous Monitoring

Watch Mode

Works as if watch sysit. Can be used within tmux status line for continuous monitoring. Eg:

set -g status-right '#[fg=black,bg=blue] #(sysit -wi 2) '

Watch mode with sysit -wi 2 has a benefit of maintaining a single process. Just using plain sysit command will also work, but that'd mean tmux spawns a new process every time.

Log Mode

At times it can be handy to log system stats, for instance, while benchmarking.
