Apache HTTP Server Version 2.2
Apache Module mod_status
|Description:||Provides information on server activity and performance|
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.
The details given are:
- The number of worker serving requests
- The number of idle worker
- The status of each worker, the number of requests that worker has performed and the total number of bytes served by the worker (*)
- A total number of accesses and byte count served (*)
- The time the server was started/restarted and the time it has been running for
- Averages giving the number of requests per second, the number of bytes served per second and the average number of bytes per request (*)
- The current percentage CPU used by each worker and in total by Apache (*)
- The current hosts and requests being processed (*)
The lines marked "(*)" are only available if

.htaccess). This may have security-related ramifications for your site.
|Description:||Keep track of extended status information for each request|
|Compatibility:||ExtendedStatus is only available in Apache 1.3.2 and later.|
This setting applies to the entire server, and cannot be enabled or disabled on a virtualhost-by-virtualhost basis. The collection of extended status information can slow down the server.
|Description:||Determine if mod_status displays the first 63 characters of a request or the last 63, assuming the request itself is greater than 63 chars.|
|Compatibility:||Available in Apache 2.2.7 and later.|
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.
If Apache is handling
GET /disk1/storage/apache/htdocs/images/imagestore1/food/apples.jpg HTTP/1.1 mod_status displays as follows:
|Off (default)||GET /disk1/storage/apache/htdocs/images/imagestore1/food/apples|
