Apache Module mod_status

Описание:Provides information on server activity and performance
Статус:Base
Идентификатор модуля:status_module
Исходный файл:mod_status.c

Summary

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 ExtendedStatus is On.

Enabling Status Support

To enable status reports only for browsers from the foo.com domain add this code to your httpd.conf configuration file

<Location /server-status>
SetHandler server-status

Order Deny,Allow
Deny from all
Allow from .foo.com
</Location>

You can now access server statistics by using a Web browser to access the page http://your.server.name/server-status

Automatic Updates

You can get the status page to update itself automatically if you have a browser that supports "refresh". Access the page http://your.server.name/server-status?refresh=N to refresh the page every N seconds.

Machine Readable Status File

A machine-readable version of the status file is available by accessing the page http://your.server.name/server-status?auto. This is useful when automatically run, see the Perl program in the /support directory of Apache, log_server_status.

It should be noted that if mod_status is compiled into the server, its handler capability is available in all configuration files, including per-directory files (e.g., .htaccess). This may have security-related ramifications for your site.

ExtendedStatus Директива

Описание:Keep track of extended status information for each request
Синтаксис:ExtendedStatus On|Off
По умолчанию:ExtendedStatus Off
Контекст:server config
Статус:Base
Модуль:mod_status
Совместимость: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.
