I've used the same config file for all servers and updated relevant hostname & IPAddress respectively, do let me know if you need additional information.

define host{
use linux-server ; Inherit default values from a template
host_name clientnagios; The name we're giving to this server
alias CentOS 5; A longer name for the server
address 10.10.2.19; IP address of the server
}
