  <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.
  </note>
  
      <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>
  
      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.

      <title>Enabling Status Support</title>
  
      To enable status reports only for browsers from the foo.com
      domain add this code to your <code>httpd.conf</code>
      configuration file 
  <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>
  
      <note><p>Note that <module>mod_status</module> 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></note>
  </section>
  
  <section>
  
      <title>Automatic Updates</title>
      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. 
  
  </section>
  
  <section>
  
      <title>Machine Readable Status File</title>
      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>. 
  
      <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>
