Host monitoring server is Ubuntu 13.10 with Nagios 3.4.1, nrpe 2.15 on both ends
The Apache Core GUI shows the default local host just fine but the newly added host/services for a remote Linux server is not showing at all. Nagios is seeing the remote host just fine as I see it being enumerated in the nagios.log ubuvaio is the remote linux box that is not showing up in Apache.
