Hi I am new to nagios ! I have added my first windows machine as stated below , now i want to add more machines , so do i need to add one more windows.cfg file with new host definations or simply add hostname in present file windows.cfg seperated by comma , like host_name server1,server2, This might seem a very stupid questions to many but still as i am new to this, so i need some help. Add a new <a href=http://nagios.sourceforge.net/docs/3_0/objectdefinitions.html#host>host</a>definition for the Windows machine that you're going to monitor. If this is the *first* Windows machine you're monitoring, you can simply modify the sample host definition in windows.cfg. Change the host_name, alias, and address fields to appropriate values for the Windows box. define host{ use windows-server ; Inherit default values from a Windows server template (make sure you keep this line!) host_name winserver alias My Windows Server address 192.168.1.2 } Good. Now you can add some service definitions (to the same configuration file) in order to tell Nagios to monitor different aspects of the Windows machine. If this is the *first* Windows machine you're monitoring, you can simply modify the sample service definitions in windows.cfg. <img src=cid:_1_060CFD24060CFAFC0023586765257427> The information contained in this e-mail message is intended only for the use of the individual or entity to which it is addressed.
