<title>The CPU and memory usage applet</title>
<para>
The <application>cpumemusage_applet</application> is a small monitor
applet which sits in your panel and tells you about your machine's
use of CPU, memory and swap. To add this
applet to a <interface>Panel</interface>,
right-click on the <interface>Panel</interface> and choose
<menuchoice>
<guimenu>Panel</guimenu>
<guisubmenu>Add to panel</guisubmenu>
<guisubmenu>Applet</guisubmenu>

<title>Usage</title>
<para>
You don't need to do anything to this applet. It will sit and
run in your panel.
</para>
<para>
The applet shows three bar charts, for CPU, memory and swap space.
If your panel is horizontal, the top bar is CPU, the middle is
memory, and the bottom is swap. If your panel is vertical, the left
bar is CPU, the middle is memory, and the right is swap.

<term>CPU</term>
<listitem>
<para>
Three colours are used here. Yellow is used for CPU activity
which does not need the kernel. Grey is used for CPU activity
by programs talking to the kernel (typically, lots of I/O such
as moving things between memory and disk). Black is the background
and represents unused CPU.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>Memory</term>
<listitem>
<para>
Four colours are used here. Yellow is used for shared memory
(memory more than one program is using). Grey is used for
buffer use (memory containing data not yet written to disk).
The greenish-yellow is used for other memory use. Green
represents unused memory.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>Swap</term>
<listitem>
<para>
Two colours are used here. Red is used for swap space in use.
Green is for unused swap. Swap is a section of the hard-drive
where the kernel puts parts of programs which are not currently
being used so that it can retrieve them easily when it needs to.
