The &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

- Disk load

### To Add &applet; to a Panel

To add &applet; to a panel, right-click on the panel, then choose Add to Panel. Select &applet; in the Add to the panel dialog, then click OK.

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

## Viewing Graphs

### Displaying Additional Graphs

- Processor

  Select this option to display the graph for CPU usage.

- Memory

  Select this option to display the graph for memory usage.

- Network

  Select this option to display the graph for network traffic.

- Swap Space

  Select this option to display the graph for swap-space usage.

- Load
