I have a Linux environment which having more than 50 servers and which is monitoring by Nagios. Now we are creating new servers using python web based GUI and we need to add them to nagios server manually.  Now we would like to add new servers automatically to nagios. is there any method to add the new servers to nagios automatically? 
Thanks in advance
I think it's not possible to automatically add client in monitoring system, but you can add it through web browser using Nconf.
