Apache mod_status module

Apache Http Server has a mod_status module that 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).

The mod_status module is disabled by default but You can configure the mod_status module by un-commenting following lines from httpd.conf

LoadModule status_module modules/mod_status.so
<IfModule mod_status.c>
ExtendedStatus On

After your httpd.conf file is reloaded try accessing the Http Server at http://localhost/server-status URL and you will get a page like this.

It gives you details on what all requests its service, how many threads are in use,..
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 (*)
