Apache provides a module to see the server-status. However the page is not too good looking. So, if you want to see a better looking information page, then you can download :

http://sourceforge.net/projects/pimpapachestat/

More details from the readme file of the project:

 

REQUIREMENTS

• On the system you want to install the pimped Apache status:
  – any webserver with php 5 (with curl; no database is needed)
• On all webservers you want to monitor:
  – apache 2.x
  – installed module mod_status and ExtendedStatus On
  – permission for the monitoring server to request the the
  alias /server-status (see below)

And tehn for installation:

INSTALL

1. Extract the files somewhere below webroot on your webserver. You
   can put to any subdirectory. It is not a must to have it in the
   webroot.
   — OR —
   checkout sources with svn client:
   cd [webroot-directory]
   svn checkout http://svn.code.sf.net/p/pimpapachestat/code/trunk apachestatus
2. Allow your server to access the server-status page on the systems
   you want to monitor
   <Location /server-status>
   SetHandler server-status
   order deny, allow
   allow from 127.0.0.1
   allow from 192.168.123.4 # enter ip of your monitoring system
   deny from all
   
3. Open http://localhost/apachestatus/ in your webbrowser.
4. In ./conf/ directory: open config_user.php and setup the systems you want
   to monitor. See config_default.php to see other thing you could override

Note: If you are using latest apache version then the entry should be :

<Location /server-info>
SetHandler server-info
Require all granted

 
CUSTOMIZATION

• change or add language: see readme in subdirectory ./lang/
• change theme:
  – make copy ./templates/default/
  – make changes in style.css and out_html.php in your copy
  – set skin in ./conf/config_user.php:
  $aUserCfg = array(
  ‘skin’ => ‘name_of_subdir’,
  );

If you have a language or a theme to share then send it to me.
