<summary>

<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>

<section id="enable">

<title>Enabling Status Support</title>

<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>

<example>

&lt;Location /server-status&gt;<br />

SetHandler server-status<br />

<br />

Order Deny,Allow<br />

Deny from all<br />

Allow from .foo.com<br />

&lt;/Location&gt;

</example>

<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>

</section>

<section id="autoupdate">

<title>Automatic Updates</title>

<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>

</section>

<section id="machinereadable">

<title>Machine Readable Status File</title>

<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>

<note>

<strong>It should be noted that if <module>mod_status</module> 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>

<description>Keep track of extended status information for each

request</description>

<syntax>ExtendedStatus On|Off</syntax>

<default>ExtendedStatus Off</default>

<contextlist><context>server config</context></contextlist>

<compatibility>ExtendedStatus is only available in Apache 1.3.2 and

later.</compatibility>

<usage>

<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>
