<h3>Apache HTTP Server Version 1.3</h3>

<h1 align="CENTER">Module mod_status</h1>
<p>This module provides information on server activity and
performance.</p>

rel="Help"><strong>Status:</strong></a> Base<br />
<a href="module-dict.html#SourceFile"

<a href="module-dict.html#ModuleIdentifier"
rel="Help"><strong>Module Identifier:</strong></a>
status_module<br />
<a href="module-dict.html#Compatibility"
rel="Help"><strong>Compatibility:</strong></a> Available in
Apache 1.1 and later.</p>
<h2>Summary</h2>
<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 children serving requests</li>
<li>The number of idle children</li>
<li>The status of each child, the number of requests that
child has performed and the total number of bytes served by
the child (*)</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 child and in
total by Apache (*)</li>
<li>The current hosts and requests being processed (*)</li>
</ul>
<p>Details marked "(*)" are only available with
<code>ExtendedStatus On</code>.</p>
<h2>Directives</h2>
<ul>
<li><a href="#extendedstatus">ExtendedStatus</a></li>
</ul>
<h2>Enabling Status Support</h2>
To enable status reports only for browsers from the foo.com
domain add this code to your <code>httpd.conf</code>
configuration file
<pre>
<Location /server-status>
SetHandler server-status
Order Deny,Allow
Deny from all
Allow from .foo.com
</Location>
</pre>
<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>
<p>Alternatively, if you have <code>lynx</code> installed, you can
also get a server statics report from the command line by running
the command <code>apachectl status</code>, or, for the extended
status report, <code>apachectl fullstatus</code>. See the <a
href="../programs/apachectl.html">apachectl</a> documentation for
additional details.</a><p>
<p>Note that mod_status will only work when you are running
Apache in <a href="core.html#servertype">standalone</a> mode
and not <a href="core.html#servertype">inetd</a> mode.</p>
<h3>Automatic Updates</h3>
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.
<h3>Machine Readable Status File</h3>
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>.
<blockquote>
<strong>It should be noted that if <samp>mod_status</samp> 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>,
<samp>.htaccess</samp>). This may have security-related
ramifications for your site.</strong>

<p>This directive controls whether the server keeps track of
extended status information for each request. This is only
useful if the status module is enabled on the server.</p>
<p>This setting applies to the entire server, and cannot be
enabled or disabled on a virtualhost-by-virtualhost basis.</p>
