Apache Template Config

The Apache template collects server statistics over HTTP from /server-status?auto, using Apache's mod_status module. These examples allow local access. Check the mod_status documentation for the available statistics and use the endpoint on the server being monitored.

CentOS and Red Hat configuration

Check whether the installed Apache configuration already loads mod_status. Add the module load only if it is missing, then configure the status location in the site's Apache configuration, for example under /etc/httpd/conf.d:

LoadModule status_module modules/mod_status.so
ExtendedStatus On

<Location /server-status>
    SetHandler server-status
    Require local
</Location>

With administrator privileges, test the configuration before reloading a running service:

apachectl configtest && systemctl reload httpd

Debian configuration

Create /etc/apache2/conf-available/80-server-status.conf with:

ExtendedStatus On

<Location /server-status>
    SetHandler server-status
    Require local
</Location>

Enable the module and configuration with administrator privileges. Reload only if the configuration test succeeds:

a2enmod status
a2enconf 80-server-status
apache2ctl configtest && systemctl reload apache2

Verify the collection endpoint

Request http://127.0.0.1/server-status?auto locally and check for the expected machine-readable statistics. Then verify collection through Cacti under the account and from the host that actually runs the helper.

Require local rejects a collector on a different host. For remote collection, configure access for the intended collector addresses and network path rather than making server-status public. The package does not configure the target's Apache service or access controls for you.
