Using the duplicate_foreach property of a service definition

services_duplicate_foreach

**Service definition duplicate_foreach**

This is used to generate serveral service with only one service declaration. 
Alignak understands this statement as : “Create a service for each key in the variable”. 
Usually, this statement come with a “$KEY$” string in the service_description (to have a different name) and 
in the check_command (you also want a different check). 

Moreover, one or several variables can be associated to each key. 
Then, values can be used in the service definition with $VALUE$ or $VALUEn$ macros.

define host {
  host_name    linux-server
  ...
  _partitions   var $(/var)$, root $(/)$
  _openvpns   vpn1 $(tun1)$$(10.8.0.1)$, vpn2 $(tun2)$$(192.168.3.254)$
  ...
}

define service{
       host_name               linux-server
       service_description     disk-$KEY$
       check_command           check_disk!$VALUE$
       ...
       duplicate_foreach       _partitions
}

define service{
       host_name               linux-server
       service_description     openvpn-$KEY$-check-interface
       check_command           check_int!$VALUE1$
       ...
       duplicate_foreach       _openvpns
}

define service{
       host_name               linux-server
       service_description     openvpn-$KEY$-check-gateway
       check_command           check_ping!$VALUE2$
       ...
       duplicate_foreach       _openvpns
}
