# CPU widget
|
|
|
|
This widget shows the average CPU load among all cores of the machine:
|
|
|
|
|
|
|
|
## 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.
|
|
|
|
## Customization
|
|
|
|
It is possible to customize widget by providing a table with all or some of the following config parameters:
|
|
|
|
| Name | Default | Description |
|
|
|---|---|---|
|
|
| `width` | 50 | Width of the widget |
|
|
| `step_width` | 2 | Width of the step |
|
|
| `step_spacing` | 1 | Space size between steps |
|
|
| `color` | `beautiful.fg_normal` | Color of the graph |
|
|
|
|
### Example
|
|
|
|
```lua
|
|
cpu_widget({
|
|
width = 70,
|
|
step_width = 2,
|
|
step_spacing = 0,
|
|
color = '#434c5e'
|
|
})
|
|
```
|
|
|
|
The config above results in the following widget:
|
|
|
|
|
|
|
|
## Installation
|
|
|
|
Clone/download repo and use widget in **rc.lua**:
|
|
|
|
```lua
|
|
local cpu_widget = require("awesome-wm-widgets.cpu-widget.cpu-widget")
|
|
...
|
|
s.mytasklist, -- Middle widget
|
|
{ -- Right widgets
|
|
layout = wibox.layout.fixed.horizontal,
|
|
...
|
|
-- default
|
|
cpu_widget(),
|
|
-- or custom
|
|
cpu_widget({
|
|
width = 70,
|
|
step_width = 2,
|
|
step_spacing = 0,
|
|
color = '#434c5e'
|
|
})
