Apache Module mod_status

Available Languages:  en  |  ko 

Description:Provides information on server activity and performance
Module Identifier:status_module
Source File:mod_status.c


Warning: 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.

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:

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.




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

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

Note that mod_status will only work when you are running Apache in standalone mode and not inetd mode.


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 Directive

Description:Keep track of extended status information for each request
Syntax:ExtendedStatus On|Off
Default:ExtendedStatus Off
Context:server config
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.
