Statis

Statis is a system info and monitoring tool based on desktop notifications. Its purpose is similar to that of traditional status bars or CLI tools, but with the explicit goal of staying out of the way while not being used – saving screen space and system resources. To this end, all its output occurs through your notification daemon, making it ideal for quick access via key bindings.

Features

• 10 built-in notifiers for resource usage (CPU, RAM, etc.), general info, and more
• Straightforward monitoring & alerts for many of said notifiers' measurements
• Notification-based output to enable more minimalist, status bar–less desktops
• Process only runs for output or while monitoring, saving on system resources

Installation

Requirements

• Python 3.7+
• Your favorite notification daemon
• libnotify (not required when using Dunst)

Stable Release

pip install --user statis

Development Version

git clone https://gitlab.com/BVollmerhaus/statis
cd statis
pip install --user .

Usage

Direct Invocation

Each of Statis' outputs is provided by a corresponding notifier, multiple of which are generally grouped into modules.

statis [options] [module [notifier] [notifier_args...]]

A notifier is run by specifying its module and name. For example, the memory module's used notifier is invoked with:

statis memory used

If a notifier's name is identical to its containing module, it can also be invoked with just that:

statis time

Additional arguments may be passed to both statis and, if applicable, the invoked notifier:

statis --urgency "low" date --format "Week %W"

This includes -h to display further usage information and list all supported arguments.

Monitoring

Many notifiers can continuously monitor their measurement and alert if it exceeds a certain threshold or changes at all.

This is done via the -m argument, which may either contain a threshold in the format [<|>][=] <value> <unit> at which to alert, or an empty string ("") to do so on all changes. Whether a notifier supports monitoring and with which units is part of its help message.

# Alert when memory usage exceeds 4 GB
statis -m "4GB" memory used

# Alert when used swap space is 2 GB or more
statis -m ">=2GB" memory used-swap

Most notifiers also support percentage-based monitoring by supplying % as the threshold unit:

statis -m "75%" memory used

Key Binding Examples

Statis itself does not implement key binding; please use your DE/WM's native functionality for this.

i3

bindsym $mod+c exec --no-startup-id statis cpu usage

Tip: i3's binding modes may be especially useful for this purpose.

awesome

awful.key({ modkey }, "c", function()
  awful.spawn("statis cpu usage", false)
end)
