<h3>Summary</h3>
<p>The Status module allows a server administrator to find out
how well their server is performing. A HTML page is presented
that gives the current server statistics in an easily readable
form. If required this page can be made to automatically
refresh (given a compatible browser). Another page gives a
simple machine-readable list of the current server state.</p>
<p>The details given are:</p>
<ul>
<li>The number of worker serving requests</li>
<li>The number of idle worker</li>
<li>The status of each worker, the number of requests that
worker has performed and the total number of bytes served by
the worker (*)</li>
<li>A total number of accesses and byte count served (*)</li>
<li>The time the server was started/restarted and the time it
has been running for</li>
<li>Averages giving the number of requests per second, the
number of bytes served per second and the average number of
bytes per request (*)</li>
<li>The current percentage CPU used by each worker and in
total by Apache (*)</li>
<li>The current hosts and requests being processed (*)</li>
</ul>
<p>A compile-time option must be used to display the details
marked "(*)" as the instrumentation required for obtaining
these statistics does not exist within standard Apache.</p>

<h2><a name="enable" id="enable">Enabling Status Support</a></h2>
<p>To enable status reports only for browsers from the foo.com
domain add this code to your <code>httpd.conf</code>
configuration file</p>
<div class="example"><p><code>
<Location /server-status><br />
SetHandler server-status<br />
<br />
Order Deny,Allow<br />
Deny from all<br />
Allow from .foo.com<br />
</Location>
</code></p></div>
<p>You can now access server statistics by using a Web browser
to access the page
<code>http://your.server.name/server-status</code></p>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="autoupdate" id="autoupdate">Automatic Updates</a></h2>
<p>You can get the status page to update itself automatically if
you have a browser that supports "refresh". Access the page
<code>http://your.server.name/server-status?refresh=N</code> to
refresh the page every N seconds.</p>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="machinereadable" id="machinereadable">Machine Readable Status File</a></h2>
<p>A machine-readable version of the status file is available by
accessing the page
<code>http://your.server.name/server-status?auto</code>. This
is useful when automatically run, see the Perl program in the
<code>/support</code> directory of Apache,
<code>log_server_status</code>.</p>
<div class="note">
<strong>It should be noted that if <code class="module"><a href="../mod/mod_status.html">mod_status</a></code> is
compiled into the server, its handler capability is available
in <em>all</em> configuration files, including
<em>per</em>-directory files (<em>e.g.</em>,
<code>.htaccess</code>). This may have security-related
ramifications for your site.</strong>

</table>
<p>This setting applies to the entire server, and cannot be
enabled or disabled on a virtualhost-by-virtualhost basis.
The collection of extended status information can slow down
the server.</p>
