<p>This worked example will show hot to setup a graph that is periodically generated
offline to show Spam statistics for a mail server. The graph will show daily
summaries for the three things; <span class="bold"><strong>a)</strong></span> The total number
of identified spam mails <span class="bold"><strong>b)</strong></span> The number of
immediately deleted spams and <span class="bold"><strong>c)</strong></span> The number of
suspected spams that was stored in the "spam" folder instead of being immediately
deleted.</p>
<p>An example of the graph we will generate is shown in <a class="xref" href="ch34.html#fig.spam-stats" title="Figure 34.1. Spam statistics">Figure 34.1. Spam statistics</a></p>
<div class="figure"><a name="fig.spam-stats"></a><p class="title"><b>Figure 34.1. Spam statistics</b></p><div class="figure-contents">
<div class="mediaobject"><img src="images/spamstat.png" alt="Spam statistics"></div>
</div></div><br class="figure-break">
<p>The graph above makes two assumption;</p>
<p>
</p><div class="orderedlist"><ol class="orderedlist" type="1"><li class="listitem">
<p>The spam setup has two levels of identifications and how spams are
handled. Suspected email are either deleted immediately (by sending them
to <span class="command"><strong>dev/null</strong></span>) or storing the email in the users spam
folder.</p>
</li><li class="listitem">
<p>The log files from the mail server are available for analysis.</p>
</li></ol></div><p>
</p>
<p>In the following we will construct a complete PHP command line script that will be
run periodically and analyse the email logs and produce a graph similar to what is
shown above. The script assume that the log file uses <span class="command"><strong>procmail</strong></span>
log format so that the folder where each mail is stored are logged.</p>
<p>
</p><div class="warning" title="Warning" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Warning</h3>
<p>For very high load email servers doing log file analysis in PHP is
probably not a very good idea due to performance reasons in regards to both
time and memory constraints. We do not make any claim that the scripts below
is enough optimized to be used on high volume mail servers.</p>
</div><p>
</p>
<p>The script will consist of three parts</p>
<div class="orderedlist"><ol class="orderedlist" type="1"><li class="listitem">
<p>A parser to scan the log file and create the data</p>
</li><li class="listitem">
<p>A suitable graph script to create an accumulated bar graph</p>
</li><li class="listitem">
<p>Uploading of the created image file with the graph to a server where
it will be displayed</p>
</li></ol></div><p>We will therefore use three classes that corresponds to each step
above. </p>
<p>To define the different files and ftp credentials we will use the following
symbolic constants which will need to be defined depending on the system setup.
Constants that must be adjusted is marked as <code class="code">"..."</code>.</p>
