- <div class="note">
- <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

- <div class="example"><p><code>

-
-
- <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>
