# CPU widget
|
|
|
|
This widget shows the average CPU load among all cores of the machine:
|
|
|
|
{:.center-image}
|
|
|
|
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](http://colby.id.au/calculating-cpu-usage-from-proc-stat/) and rewrote it in Lua, which was quite simple.
|
|
So awesome simply reads the first line of /proc/stat:
|
|
|
|
```bash
|
|
$ cat /proc/stat | grep '^cpu '
|
|
cpu 197294 718 50102 2002182 3844 0 2724 0 0 0
|
|
```
|
|
|
|
and calculates the percentage.
|
|
|
|
## Installation
|
|
|
|
1. Clone this repo under **~/.config/awesome/**
|

|
```bash
|
|
git clone https://github.com/streetturtle/awesome-wm-widgets.git ~/.config/awesome/
|
|
```
|
|
|
|
1. Require spotify-widget at the beginning of **rc.lua**:
|
|
|
|
```lua
|
|
local cpu_widget = require("awesome-wm-widgets.cpu-widget.cpu-widget")
|
|
```
|
|
|
|
1. Add widget to the tasklist:
|
|
|
|
```lua
|
|
s.mytasklist, -- Middle widget
|
|
{ -- Right widgets
|

layout = wibox.layout.fixed.horizontal,

...
|

cpu_widget,
