<h3>Summary</h3>
|
||
|
||
<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>The lines marked "(*)" are only available if
|
||
<code class="directive"><a href="#extendedstatus">ExtendedStatus</a></code>
|
||
is <code>On</code>.</p>

<p>mod_status with <code>ExtendedStatus On</code>
|

displays the actual request being handled.
|

For historical purposes, only 63 characters of the request
|
||
are actually stored for display purposes. This directive
|
||
controls whether the 1st 63 characters are stored (the previous
|
||
behavior and the default) or if the last 63 characters are. This
|
||
is only applicable, of course, if the length of the request is
|
||
64 characters or greater.</p>
