+
+<para
+>&ksysguard; is the &kde; Task Manager and Performance Monitor. It features a client/server architecture that allows monitoring of local as well as remote hosts. The graphical front end uses so-called sensors to retrieve the information it displays. A sensor can return simple values or more complex information like tables. For each type of information, one or more displays are provided. Displays are organised in work sheets that can be saved and loaded independently from each other. So, &ksysguard; is not only a simple task manager but also a very powerful tool to control large server farms.</para>

+
+<sect1 id="getting-started">
+<title
+>Getting started</title>
+
+<para
+>&ksysguard; can be started from the start menu, using the entry <guimenuitem
+>KDE System Guard</guimenuitem
+> in the <guimenu
+>Systems</guimenu
+> menu. Alternatively, you can start it by typing <command
+>ksysguard</command
+> in a terminal.</para>
+
+<para
+>The &ksysguard; main window consists of a menu bar, an optional tool bar and status bar, the sensor browser and the work space. When first started you see your local machine listed as <guilabel
+>localhost</guilabel
+> in the sensor browser and 2 pages in the work space area. This is the default setup.</para>
+
+<para
+>This default setup is sufficient enough for an inexperienced user to do some system management. An experienced user or even a system administrator of a large computer lab has different needs. To address a wide range of users, &ksysguard; is highly flexible.</para>
+</sect1>
+
+<sect1 id="the-sensor-browser">
+<title
+>The Sensor Browser</title>
+
+<para
+>The sensor browser displays the registered hosts and their sensors in a tree form. Click on the tree handles to open or close a branch. Each sensor monitors a certain system value.</para>
+
+<sect2 id="connectingtootherhosts">
+<title
+>Connecting to other hosts</title>
+
+<para
+>To connect to a new host use <guimenuitem
+>Connect Hosts</guimenuitem
+> from the <guimenu
+>File</guimenu
+> menu. A dialogue box will appear and allows you to enter the name of the host you want to connect to. Below the name you can choose the connection method. The default is <application
+>ssh</application
+>, the secure shell. Alternatively the <application
+>rsh</application
+>, the remote shell, or the daemon mode can be used. Click <guibutton
+>OK</guibutton
+> to establish the connection. Shortly afterwards the new host will appear in the sensor browser and you can browse the list of sensors.</para>
+
+<para
+>To establish a connection, a program called <application
+>ksysguardd</application
+>, that can be started in the following two modes, must be installed on the new host.</para>
+
+<variablelist>
+<varlistentry>
+<term
+>daemon mode</term>
+<listitem>
+<para
+>You can start <application
+>ksysguardd</application
+> at boot time in <guilabel
+>Daemon</guilabel
+> mode by adding <parameter
+>-d</parameter
+> as the argument. In this case, you have to select daemon mode at the connection dialogue of <application
+>ksysguard</application
+>. A disadvantage of this connection type is that you won't be able to kill or renice a process with the <guilabel
+>Process Controller</guilabel
+> and the data exchange over network won't be encrypted.</para>
+</listitem>
+</varlistentry>
+<varlistentry>
+<term
+>shell mode</term>
+<listitem>
+<para
+>In this mode <application
+>ksysguardd</application
+> is started at connecting time by <application
+>ksysguard</application
+>. To make that possible, its location needs to be included in your <envar
+>PATH</envar
+>. Unfortunately the ssh does not source your <filename
+>.profile</filename
+> file, so your regular <envar
+>PATH</envar
+> setting will not be available. Instead it uses a default <envar
+>PATH</envar
+> like <parameter
+>/bin:/usr/bin</parameter
+>. Since it is very likely that &kde; is not installed in these folders you need to create or update a file in your home folder. The file is called <filename
+>environment</filename
+> and needs to be in a hidden folder called <filename
+>.ssh</filename
+>. See the manual page for <application
+>ssh</application
+> for more details. The file needs to contain a line similar to:</para>
+
+<screen
+><userinput
+>PATH=/bin:/usr/bin:/opt/kde/bin</userinput
+>
+</screen>
+
+<para
+>assuming that <application
+>ksysguardd</application
+> can be found under <filename
+>/opt/kde/bin/ksysguardd</filename
+>.</para>
+
+<tip
+><para
+>When using <application
+>ssh</application
+> you should make sure that you have your <filename
+>identity.pub</filename
+> installed on the remote machine and the host key of the remote machine is already registered on your machine. The easiest way to check this is to type <command
+>ssh <option
+>remotehost ksysguardd</option
+></command
+> in a shell. If you are greeted by <application
+>ksysguardd</application
+> you can type <userinput
+>quit</userinput
+> and everything is in order.</para
+></tip>
+</listitem>
+</varlistentry>
+</variablelist>
+
+<note
+><para
+>For experts: <application
+>ksysguardd</application
+> is a very small program that is only linked against the libc. So it can also be used on machines that do not have a fully blown &kde; installation, such as servers. If you choose the custom command option in the host connector you need to specify the complete command to start <application
+>ksysguardd</application
+>.</para

+>The Work Space</title>
+
+<para
+>The work space is organised as work sheets. Select <guimenuitem
+>New</guimenuitem
+> from the <guimenu
+>File</guimenu
+> menu to create a new work sheet. A dialogue will appear where you can set the name, the dimension and the update interval of the work sheet. To remove a work sheet again, select <guimenuitem
+>Close</guimenuitem
+> from the <guimenu
+>File</guimenu
+> menu. Any modifications will be saved to the work sheet file. If a work sheet has never been saved, you will be asked for a file name. Work sheets consist of cells organised as a grid.</para>
+
+<para
+>Each cell can be filled with a display for one or more sensors. You can fill a cell by dragging a sensor from the sensor browser and dropping it over the cell. If there is more than one type of display available for that type of sensor, a popup menu will appear. You can then select which display you prefer to use. Certain types of displays can display more than one sensor. Add more sensors to a display by dragging them over from the sensor browser and dropping them over the already existing display.</para>
+
+<para
+>Work sheets can be configured by clicking <guimenuitem
+>Configure Worksheet </guimenuitem
+> at the <guimenu
+>Edit</guimenu
+> menu. In the appearing dialogue you can set the dimension and the update interval. This update interval is used by all displays of the worksheet, which has the <guilabel
+>use update interval of worksheet</guilabel
+> set in its timer configuration dialogue.</para>
+
+<para
+>The entry <guimenuitem
+>Configure Style</guimenuitem
+> of the <guimenu
+>Settings</guimenu
+> menu gives you the possibility to configure the global style attributes and apply them to the current active worksheet.</para>
+
+<para
+>Displays can be configured by clicking with the right mouse button on them. A popup menu appear where you can select whether you want to change the properties of that display, remove it from the work sheet, change its update interval type and value or pause and restart its updating.</para>
+
+<sect2 id="signal-plotter">
+<title
+>Signal Plotter</title>
+
+<para
+>The signal plotter prints samples of one or more sensors over time. If, several sensors are displayed, the values are piled in different colours. If the display is large enough a grid will be displayed to show the range of the plotted samples. By default, the automatic range mode is active so the minimum and maximum values will be set automatically. Sometimes you want fixed minimum and maximum values. In that case, you can deactivate automatic range mode and set the values in the properties dialogue.</para>
