Apache Server

Prerequisites

Centreon Plugin

Install this plugin on each needed poller:

yum install centreon-plugin-Applications-Webservers-Apache-Serverstatus

mod_status and extendedstatus

Warning: The following procedure is an example. Cannot be applied on all context.

The module mod_status allows the generation of a live Apache report, available on a dedicated web page. This report is used to generate statistics in Centreon. To activate this module, you have to open your httpd configuration file:

$ vi /etc/httpd/conf/httpd.conf

and check that:

• The module is loaded by Apache:

    LoadModule status_module modules/mod_status.so

• If not already configured, add the followings lines:

        <Location /server-status>
            SetHandler server-status 
            Order Deny,Allow
            Allow from <centreon-poller_@IP>
            Deny from All
        </Location>

• And finally, check that ExtendedStatus is activated (Mandatory if you wants precise statistics on query processed by the WebServer):

    ExtendedStatus On

Apache must be reloaded to take this modification into account:

$ /etc/init.d/httpd reload
