# Apache Module mod_status

Available Languages: en | ja | ko

Description: | Provides information on server activity and performance
Status: | Base
Module Identifier: | status_module
Source File: | 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`.

### Directives

### Topics

- Enabling Status Support
- Automatic Updates
- Machine Readable Status File

## 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 Directive

Description: | Keep track of extended status information for each request
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 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.
