## Feedback

To report a bug or make a suggestion regarding the &applet; applet or this manual, follow the directions in the GNOME Feedback Page.

## Introduction

### &applet; Applet

Shows &applet; applet. Displays a graph for system CPU load.

The &applet; applet displays system load information in graphical format in a panel. You can configure &applet; to display the following information for your system:

- Usage of CPU (central processing unit) time

- Memory usage

- Network traffic

- Usage of swap space

- Average system load

### To Add &applet; to a Panel

To add &applet; to a panel, right-click on the panel, then choose Add to Panel Utility &applet; .

The layout of the &applet; applet varies depending on the size and type of panel in which the applet resides.

## Usage

### To Display Additional Graphs

For information about how to add graphs for the various monitored resources, see .

### To Display the Current Usage of a System Resource

To display the current usage of a system resource, position the mouse pointer over the corresponding graph in the applet. A tooltip displays the current usage as a percentage.

### To Change the Colors in a Graph

To change the colors in a graph, perform the following steps:

1. Right-click on the applet, then choose Preferences.

2. Select the relevant tab in the Colours area of the System Monitor Preferences dialog.

3. Click on the relevant color selector button in the selected tabbed section.

4. On the Pick a Color dialog, use the color wheel or spin boxes to choose the line color for the selected parameter.

5. Click OK.

### To Display Additional System Monitor Information
