# waybar-cpu(5)

cpu module

## NAME

waybar - cpu module

## DESCRIPTION

The **cpu** module displays the current CPU utilization.

## CONFIGURATION

**interval**: \
 typeof: integer or float \
 default: 10 \
 The interval in which the information gets polled. \
 Minimum value is 0.001 (1ms). Values smaller than 1ms will be set to 1ms.

**format**: \
 typeof: string  \
 default: {usage}% \
 The format, how information should be displayed. On {} data gets inserted.

**format-icons**: \
 typeof: array/object \
 Based on the current usage, the corresponding icon gets selected. \
 The order is **low** to **high**. Or by the state if it is an object.

**max-length**: \
 typeof: integer \
 The maximum length in character the module should display.

**min-length**: \
 typeof: integer \
 The minimum length in characters the module should accept.

**align**: \
 typeof: float \
 The alignment of the label within the module, where 0 is left-aligned and 1 is right-aligned. If the module is rotated, it will follow the flow of the text.

**justify**: \
 typeof: string \
 The alignment of the text within the module's label, allowing options 'left', 'right', or 'center' to define the positioning.

**rotate**: \
 typeof: integer \
 Positive value to rotate the text label (in 90 degree increments).

**states**: \
 typeof: object \
 A number of CPU usage states which get activated on certain usage levels. See **[waybar-states(5)](/waybar-states/5.md)**.

**on-click**: \
 typeof: string  \
 Command to execute when clicked on the module.

**on-click-middle**: \
 typeof: string \
 Command to execute when middle-clicked on the module using mousewheel.

**on-click-right**: \
 typeof: string \
 Command to execute when you right-click on the module.

**on-update**: \
 typeof: string \
 Command to execute when the module is updated.

**on-scroll-up**: \
 typeof: string \
 Command to execute when scrolling up on the module.

**on-scroll-down**: \
 typeof: string \
 Command to execute when scrolling down on the module.

**smooth-scrolling-threshold**: \
 typeof: double \
 Threshold to be used when scrolling.

**tooltip**: \
 typeof: bool \
 default: true \
 Option to disable tooltip on hover.

**expand**: \
 typeof: bool \
 default: false \
 Enables this module to consume all left over space dynamically.

## FORMAT REPLACEMENTS

**{load}**: Current CPU load.

**{usage}**: Current overall CPU usage.

**{usage**{n}**}**: Current CPU core n usage. Cores are numbered from zero, so first core will be {usage0} and 4th will be {usage3}.

**{avg\_frequency}**: Current CPU average frequency (based on all cores) in GHz.

**{max\_frequency}**: Current CPU max frequency (based on the core with the highest frequency) in GHz.

**{min\_frequency}**: Current CPU min frequency (based on the core with the lowest frequency) in GHz.

**{icon}**: Icon for overall CPU usage.

**{icon**{n}**}**: Icon for CPU core n usage. Use like {icon0}.

## EXAMPLES

Basic configuration:

```
"cpu": {
	"interval": 10,
	"format": "{}% ",
	"max-length": 10
}
```

CPU usage per core rendered as icons:

```
"cpu": {
	"interval": 1,
	"format": "{icon0}{icon1}{icon2}{icon3} {usage:>2}% ",
	"format-icons": ["▁", "▂", "▃", "▄", "▅", "▆", "▇", "█"],
},
```
