CPU widget

This widget shows the average CPU load among all cores of the machine:

When the load is more than 80% the graph becomes red. You can easily customize the widget by changing colors, step width, step spacing, width and interval.

How it works

To measure the load I took Paul Colby's bash script and rewrote it in Lua, which was quite simple. So awesome simply reads the first line of /proc/stat:

$ cat /proc/stat | grep '^cpu '
cpu  197294 718 50102 2002182 3844 0 2724 0 0 0

and calculates the percentage.

Installation

  2. Require spotify-widget at the beginning of rc.lua:

    local cpu_widget = require("awesome-wm-widgets.cpu-widget.cpu-widget")

  3. Add widget to the tasklist:

    s.mytasklist, -- Middle widget
    { -- Right widgets
        layout = wibox.layout.fixed.horizontal,
        ...
        cpu_widget,
        ...
