Nagios not seeing a remote Windows machine

Post by JoshuaHilton »

Hello all, first timer to Nagios here.

I've been able to get Nagios installed and running on a Ubuntu server and can access the control page either locally or remotely. I also have the windows agent running (NSClient++) on a different server. However I can't get the monitored server to show up in Nagios. I followed the Quickstart guide on Ubuntu (http://nagios.sourceforge.net/docs/3_0/ ... buntu.html) and the guide to monitoring Windows servers (http://nagios.sourceforge.net/docs/3_0/ ... ndows.html). I can verify my configuration without returning errors. After looking through the forums and archives of the mailing list, I wasn't able to find anything relating to this (though I know it's a rather generalized kind of problem) and a request sent to the mailing list hasn't yielded anything useful either.

When looking at the Nagios webpage, I can see the "Windows Servers" group, but there are no hosts underneath it. In addition, I don't see anything other than localhost under the "Hosts" or "Services" tab. NSClient is using the local system as a user and does have access to the desktop. I am inexperienced with Ubuntu (Linux/Unix systems in general) so any and all help is greatly appreciated. However I was able to confirm that the firewall for Ubuntu was disabled.
