I have configured Nagios Core server in CentOS.Installed NSClinet++ in my Windows Host.
I successfully added the Windows Machine into Nagios Core.Host is showing UP but the services are showing Unknown.
I have changed the configuration in commands.cfg and nagios.cfg files.Add the services in Windows.cfg file with the host name.Still the Services are showing Unknown.
The best way of configuring files with .cfg extesion is to create directories in /etc/nagios/directoryname or /usr/share/nagios/directoryname for each server and it’s depend of Nagios’s release. I mean one directory for Linux servers, another directory for Windows servers, etc. Finally you have to set up each file.cfg (by server) in its own directory in nagios.cfg.
Then you have to cofigure each file in its directory the services that the server is running.
