Corresponding meta information content is obtained from the to-be-connected product based on meta information in the model of each entity. A monitoring task is configured based on the model of each entity and a functional part to which each entity belongs. The to-be-connected product is monitored based on the monitoring task and meta information content in the model of each entity.
