Apache HTTP Server Version 1.3

Module mod_status

The Status Module is only available in Apache 1.1 and later.


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.

ExtendedStatus directive

Syntax: ExtendedStatus On|Off
Default: ExtendedStatus Off
Context: server config
Status: Base
Module: mod_status
Compatibility: ExtendedStatus is only available in Apache 1.3.2 and later.

This directive controls whether the server keeps track of extended status information for each request. This is only useful if the status module is enabled on the server.

This setting applies to the entire server, and cannot be enabled or disabled on a virtualhost-by-virtualhost basis.

Enabling Status Support

To enable status reports only for browsers from the foo.com domain add this code to your access.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.
