    /** ------------------------------------------------------------------------ **/
    /** --- Icinga Admins ------------------------------------------------------ **/
    /** ------------------------------------------------------------------------ **/
    object UserGroup "Icinga Admins" {
            display_name = "Icinga 2 Admin Group"
            }
    
    object HostGroup "Icinga Admins" {

            user_groups = [ "Icinga Admins" ]
            assign where host.vars.sla == "24x7" && "Icinga Admins" in host.groups
            }
    
    apply Notification "Icinga Admins - Service Notification" to Service {
            command = "notify-service-en"

            }
    
    --- end ---
    bash#

Exemple host configuration:

    bash# cat /etc/icinga2/hosts/myhost.conf
    object Host "myhost" {
            import "generic-host"
            address                 = "1.1.1.1"

            vars.sla                = "24x7"
    
            /* Define http vhost attributes for service apply rules in `services.conf`. */

                    http_port       = 80
                    }
    
            vars.http_vhosts["myhost.domain.com HTTPS"] = {
                    http_address    = "imyhost.domain.com"
                    http_uri        = "/"
                    http_port       = 443
                    http_ssl        = "true"
                    }
    
            groups = [ "Icinga Admins" ]
            notes = "Location: Beverly Hills, 90210"
            }
