 ## httpd vHost files
 
-by default, Nagios creates its own `nagios.conf` file, which is not a vhost file and relies on the main ssd.conf. However, as Nagios might be running on a regular web server with various other web instances (not recommended through for performance reasons), we do not want to manage ssl.conf directly, hence the module creates a vhost for the ssl host.

 ## Client Connections
 
 In order to monitor clients, NAGIOS must be able to connect to them. There are multiple ways of doing so, the most common ones being NRPE and SSH.
-So far this module works through the usage of NRPE, which by default is enabled. Class cd_nagios::client::nrpe configures nrpe.cfg and opens the required firewall port on clients (optional,default).
