+<h2 id="introduction">Introduction</h2>
+<p>Sling provides a helpful functionality to track progress of requests
+being processed: The <a href="">RequestProgressTracker</a>
which is available through the <a href="">SlingHttpServletRequest</a>.</p>
+<p>This tool provides mechanims to record states of request processing and a simple
mechanism to time periods of processing. By default Sling itself uses this tool to track progress
through Sling like script resolution and calling scripts.</p>
+<p>Scripts and servlets called during Sling's request processing may themselves use
the <code>RequestProgressTracker</code> to log their own processing.</p>
+<p>Usually the data collected by the <code>RequestProgressTracker</code>
is just dropped or it may be visible for a certain number of recent requests on the <em>Recent
Requests</em> page of the Web Console. When doing load tests, though, this Web Console
page is of limited use because a lot more requests are handled than can be displayed in the
Web Console.</p>
+<p>This is where the <a href="">Request
Processing Analyzer</a> comes in handy. When deployed as a bundle it registers as a
request level servlet Filter with the Sling Main Servlet. Each request is logged in a special
file (currently fixed at <code>${sling.home}/logs/requesttracker.txt</code>) with
a header line provding core information on the request:</p>
+<li>Start time stamp in ms since the Epoch</li>
+<li>Request processing time in ms</li>
+<li>Request Method</li>
+<li>Request URL</li>
+<li>Response content type (plus character encoding if available)</li>
+<li>Response Status</li>
+<p>After that first line the complete data from the requests <code>RequestProgressTracker</code>
is dumped.</p>
+<h2 id="analyzing-the-requesttrackertxt-file">Analyzing the <code>requesttracker.txt</code>
+<p>To analyze the <code>requesttracker.txt</code> file the <em>Request
Processing Analyzer</em> module can also be used as a standalone Java application. Just
start the module using the <code>java</code> command:</p>
+<div class="codehilite"><pre><span class="nv">$</span> <span class="nv">java</span>
<span class="o">-</span><span class="n">jar</span> <span class="n">org</span><span
class="o">.</span><span class="n">apache</span><span class="o">.</span><span
class="n">sling</span><span class="o">.</span><span class="n">reqanalyzer</span><span
class="o">-</span><span class="mf">0.0.1</span><span class="o">-</span><span
class="n">SNAPSHOT</span><span class="o">.</span><span class="n">jar</span>
<span class="n">requesttracker</span><span class="o">.</span><span
+<p>The command supports two command line arguments:</p>
+<li>The tracker file (required)</li>
+<li>The number of requests to load and display from the file. This second option is
optional and may be used to limit the request information loaded to the first requests in
the file</li>
+<p>After starting and parsing the file, a window is opened showing the core request
information in simple table. This table can be sorted by any of the columns by clicking on
the column title.</p>
+<p>Clicking on any row opens a second window displaying the detail request progress
information as recorded before with the <code>RequestProgressTracker</code>.</p>
+<p>The size, location, and the widths of the table columns are persisted with the Java
Preferences API and thus when starting the application again, these settings are preserved.</p>
