Overview

mod_status renders a page with information about the server:

• number of workers serving requests and idle.
• status of each worker.

If ExtendedStatus is on, the server maintains and displays extended status information for each request.

Installation

Make sure mod_status was either compiled in the binary (mod_status.c should be in the output of httpd -l), or loaded as a dynamic module.

<Location "/status">
    SetHandler server-status
</Location>

ExtendedStatus On

If the server acts as a proxy and various URLs are being proxied, insure "/status" is not:

ProxyPass /status !

More details Location, SetHandler.
