On choisit de ne pas changer le fichier templates.cfg mais de créer un templates2.cfg

templates2.cfg

define host {

    name                         windows-tpl
    use                             windows-server
    hostgroups               windows-hosts
    register                      0
    }
 

define host {

    name                         linux-tpl
    use                             linux-server
    hostgroups               linux-hosts
    register                      0
    }

Il faudra créer les hostgroups associer (à faire à partir de YAML)

linux.cfg

define hostgroup {

    hostgroup_name          linux-hosts
    alias                   Linux Hosts
}

''windows.cfg''

define hostgroup {

hostgroup_name          windows-hosts
alias                   Windows Hosts

}

Changer la définition des hosts
''use windows-server'' en
''use windows-tpl''

Changer la définition des hosts
''use linux-server''
