The invention relates to the technical field of information, in particular to the field of monitoring operating and maintaining, and particularly discloses a method for monitoring a service system based on module finding. A correlation model configuration module, a model engine module and a monitoring model showing module are adopted in the method. The correlation model configuration module is mainly used for classifying the modules supporting the service system, concluding configuration items and providing the bottommost resource support for the module finding technology. The model engine module is used for automatically finding the modules of the service application system according to the module finding algorithm and correlating the modules. The monitoring model showing module is mainly used for uniformly showing correlated topology monitoring models. According to the method, hardware at the bottom layer of the service system can be found, a corresponding topological structure can be formed, the software layer role played by the hardware at the bottom layer in the service system can be found, comprehensive monitoring is vertically carried out on the service system from top to bottom and from software to hardware, and monitoring visuality and accuracy are greatly improved.
