<P>From version 1.50, you can use the freeware software MRTG to produce
really nice graphical statistics on your web site. For an example
try
<A HREF="http://www.gb7mbc.net/mrtg/stats.html">http://www.gb7mbc.net/mrtg/stats.html</A>.</P>
<P>The following should help you get it all working.</P>
<P>First you need to download the latest version of MRTG from
<A HREF="http://people.ee.ethz.ch/~oetiker/webtools/mrtg/">http://people.ee.ethz.ch/~oetiker/webtools/mrtg/</A>.
You will also need the following files..</P>
<P>
<BLOCKQUOTE><CODE>
<PRE>
libpng-1.0.14.tar.gz
zlib-1.1.4.tar.gz
gd-1.8.3.tar.gz
</PRE>
</CODE></BLOCKQUOTE>
</P>
<P>Login to your machine as the root user, put all the downloaded files
in /usr/local/src/ (or wherever you prefer) and untar and compile them.
All the information to compile and install these sources come with them.
After compilation and installation, you will find MRTG in /usr/local/mrtg-2.</P>
<P>Now copy all the files in /usr/local/src/mrtg-2.9.22/images/ to
/spider/html/mrtg/</P>
<P>You now need to make 2 symbolic links like below...</P>
<P>
<BLOCKQUOTE><CODE>
<PRE>
ln -s /usr/local/mrtg-2/bin/mrtg /usr/bin/mrtg
ln -s /usr/local/mrtg-2/lib/mrtg2 /usr/lib/mrtg2
</PRE>
</CODE></BLOCKQUOTE>
</P>
<P>Now login to the cluster with your sysop callsign and run the command
"mrtg all".</P>
<P>Now you are nearly there! Login as the sysop user and change to the
/spider/html/mrtg/ directory. Now run the command <EM>indexmaker</EM> as
shown below...</P>
<P>
<BLOCKQUOTE><CODE>
<PRE>
indexmaker --output stats.html --columns=1 --title "MRTG statistics for GB7DJK" ../../mrtg/mrtg.cfg
</PRE>
</CODE></BLOCKQUOTE>
</P>
<P>Changing the callsign for your own cluster callsign of course!</P>
<P>And finally you need to login as the root user and create one last
symbolic link. Where this points will depend on where your html
documents are kept. For RedHat systems you use...</P>
<P>
<BLOCKQUOTE><CODE>
<PRE>
ln -s /home/sysop/spider/html/mrtg /home/httpd/html/mrtg
</PRE>
</CODE></BLOCKQUOTE>
</P>
<P>and for SuSE systems...</P>
<P>
<BLOCKQUOTE><CODE>
<PRE>
ln -s /home/sysop/spider/html/mrtg /usr/local/httpd/htdocs/mrtg

<P>If you now point your browser to your website as below it should all
be happening!</P>
<P>
<BLOCKQUOTE><CODE>

</CODE></BLOCKQUOTE>
</P>
<P>Of course, to get the stats to update, you need to add some information
in the spider crontab file as below...</P>
