<strong>Warning:</strong> This document has not been updated
|
||
to take into account changes made in the 2.0 version of the
|
||
Apache HTTP Server. Some of the information may still be
|
||
relevant, but please use it with care.
|
||
</div>
|
||
|
||
<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>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>

|
||
|
||
|
||
<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 class="note"><p>Note that <code class="module"><a href="../mod/mod_status.html">mod_status</a></code> will only work

when you are running Apache in <a href="core.html#servertype">standalone</a> mode and not

|
||
|
||
|
||
<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>Machine Readable Status File</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>
