sysit
Get system resources overview in 40 characters. For usage details, try --help

USAGE:
    sysit [FLAGS] [OPTIONS]

FLAGS:
    -c, --colors       force output to be always colorized
    -h, --help         Prints help information
    -l, --log          run in log mode (will continuously append a row to standard output)
        --no-colors    force output to be never colorized
    -V, --version      Prints version information
    -w, --watch        run in watch mode (will act as if running with the watch)

OPTIONS:
    -i, --interval <interval>
            update interval in seconds for watch/log mode [default: 1]

        --threshold-cpu-high <threshold-cpu-high>
            the threshold for high cpu usage (higher values will be rendered in red) [default:
            80.0]

        --threshold-cpu-medium <threshold-cpu-medium>
            the threshold for medium cpu usage (higher values will be rendered in yellow) [default:
            50.0]

        --threshold-memory-high <threshold-memory-high>
            the threshold for high memory usage (higher values will be rendered in red) [default:
            80.0]

        --threshold-memory-medium <threshold-memory-medium>
            the threshold for medium memory usage (higher values will be rendered in yellow)
            [default: 50.0]

        --threshold-temp-hot <threshold-temp-hot>
            the threshold for high temperature (higher values will be rendered in red) [default:
            75.0]

        --threshold-temp-warm <threshold-temp-warm>
            the threshold for warm temperature (higher values will be rendered in yellow) [default:
            55.0]

Reasoning

When working headlessly with tmux or even when working on a desktop, being able to quickly see basic system informatino can be useful. There's btm (also based on sysinfo, heim), but you have to actively switch to them.

For instance, when overclocking the RPi, it makes sense to monitor the CPU frequency and temperature. Inspired by cpu-temp-speed on Manjaro, which has been quite useful in tuning the overclock and colling system configuration.

Usage

From the console

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

M: 8% | C: 0% @ 1100 MHz | T: 54°C

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=yellow] #(sysit -wi 2) #[fg=colour235,bg=colour252,bold] %a %d %b %H:%M:%S #[fg=colour252,bg=colour238,nobold]#[fg=colour245,bg=colour238,bold]'

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.
