 * Important: Before making changes you must read Apache, Nagios and NagVis websites, about security risks and recomendations.

MediaWiki must be able to pull status without user authentication so you must change your webserver setup. There are several solutions and your configuration could be different depending on your security needs.

Configuration example for Nagios Web Server
Modify nagios.conf for apache (ex: Debians servers: /etc/apache2/conf.d/nagios.conf) in all your NagVis servers:

ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"  Options ExecCGI AllowOverride All Order allow,deny AuthName "Nagios Access" AuthType Basic AuthUserFile /usr/local/nagios/etc/htpasswd.users Require valid-user Allow from MediaWiki_Server_IP SetEnv REMOTE_USER nagiosadmin Satisfy Any  Alias /nagios "/usr/local/nagios/share"  Options None AllowOverride All Order allow,deny AuthName "Nagios Access" AuthType Basic AuthUserFile /usr/local/nagios/etc/htpasswd.users Require valid-user Allow from MediaWiki_Server_IP SetEnv REMOTE_USER nagiosadmin Satisfy Any
