将 UserA 分配给 HostA 作为联系人.不要为 HostA 的服务定义/分配任何联系人.然后服务将继承主机的联系信息.请参阅文档中表格的第一行:

Assign UserA to HostA as the contact. Don't define/assign any contacts to the services for HostA. Then the services will inherit the contact info for the Host. See the first line in the table in the docs:

或者，您可以将联系人放入联系人组.

Optionally, you can put the contact into a contactgroup.
