<title>Introduction</title>
<para>
&kcpuload; is a small program for Kicker (the TDE panel). It
shows a recent history of CPU usage in the form of one or two
configurable diagrams in the system tray.
These diagrams have settings for colors and various different styles.
</para>
<para>
Note that it isn't the real system load that is shown, but the percent
used of the total CPU power, which is calculated from the number of
CPU ticks between each update.
</para>
<para>
If there is more than one CPU on the system, the combined CPU usage
from both can be shown, or you can choose to have one separate diagram
for each CPU.
</para>
<para>
Left click on a diagram to bring up a small information box which
will show the exact CPU usage in text form.
</para>
<para>
Note that using a slower update interval will give a more stable
and accurate diagram without flicker.
</para>
</chapter>
<chapter id="configuration">
<title>Configuration</title>
<para>
To configure &kcpuload;, click on the diagram in the system tray
using your right mouse button. A configuration menu will appear.
</para>
<para>
The settings chosen in the configuration menu are saved automatically
to the &kcpuload; configuration file as soon as they are set. There
is no need to save the settings manually.
</para>
<variablelist>
<varlistentry>
<term>SMP (Dual CPU) Support</term>
<listitem>
<para>
If you don't have an SMP system, none of the SMP options will
appear in the menu. If you do, you will be presented with both an
SMP on/off option at the top of the options menu, and
(when SMP is turned on) a second color settings menu for the
second diagram.
</para>
<para>
If you choose to have SMP off, you will only see one diagram
showing the values from both CPUs combined. If you choose to
have SMP on, there will be one diagram for each CPU showing their
individual loads.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>Changing the Update Speed</term>
<listitem>
<para>
Choose <guilabel>Speed</guilabel> from the configuration menu to
change how frequently the diagram(s) are updated.
Choose a lower value to get a more responsive diagram.
Choose a higher value to get a slower but more stable and less
flickering diagram.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>Splitting the System and User Loads</term>
<listitem>
<para>
Enable the <guilabel>Graph Splitting</guilabel> option to have the
diagram split into an upper
part and a lower part. The upper part of the diagram will
show the user load (the apps you're using on a day-to-day basis).
The lower part which is a white scale will show the system load
(which includes daemons and other low level parts of the system
and kernel).
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>Changing Diagram Style</term>
<listitem>
<para>
The <guilabel>Style</guilabel> option in the configuration menu
will let you change the look of the diagram. Options include
a <guilabel>Lines</guilabel> option which only draws a straight line
across the diagram, a <guilabel>Bars</guilabel> option which draws
a bar graph, and a <guilabel>Shaded</guilabel> option which shades
the diagram in a nice black-to-color tone.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>Soft Curves</term>
<listitem>
<para>
The <guilabel>Soft Curves</guilabel> option can be used to smooth
the diagram(s). This means that diagrams won't show very fast changes,
but instead move slowly up and down with a little delay on the
movements. This feature can make the diagrams look better,
especially when the update interval is set to a fast flickering rate.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>Labels and Grid</term>
<listitem>
<para>
These options control what is displayed behind the diagram(s).
The <guilabel>Labels</guilabel> option will turn on small text
labels in the upper left corner of each diagram showing which
CPU the diagram represents.
The <guilabel>Grid</guilabel> option will toggle a background
grid of horizontal lines.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>Changing Diagram Colors</term>
<listitem>
<para>
Each CPU diagram has a corresponding <guilabel>Color</guilabel>
option in the menu; this can be used to change the color of the
diagram.
</para>

<varlistentry>
<term>Active and Clear</term>
<listitem>
<para>
These two functions are located at the top of the options menu.
</para>
<para>
The <guilabel>Active</guilabel> option is the power switch
for the whole program. This can be used to suspend the diagram
so that it doesn't measure any readings.
</para>
<para>
The <guilabel>Clear</guilabel> option will erase all readings and
start afresh with an empty diagram.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>Pop-Up Information Dialog</term>
<listitem>
<para>
Left click on one of the diagrams to bring up a small pop-up
information box. To hide it, left click on the diagram again,
or right click on the pop-up itself.
</para>
<para>
While the pop-up is shown, you can move it around with the left
mouse button. This pop-up is both sticky and always on top, so
that you can have it in a corner all the time if you like.

If &kcpuload; is still running when KDE is shut down, it will
restart when KDE is restarted.
