System health degree determination method, device and equipment and readable storage medium

The invention provides a system health degree determination method, apparatus and device, and a readable storage medium, and relates to the technical field of Internet of Things. The method comprises the following steps: acquiring current state information of a target system; calculating the relationship similarity between the current state information of the target system and the entities in the knowledge graph; querying corresponding fault category and fault level data in a fault knowledge element library according to the relationship similarity; and calculating the health degree of the target system according to the fault category data, the fault level data and functional data of the target system. According to the system health degree determination method provided by the embodiment of the invention, the knowledge graph of health degree evaluation is constructed based on the multi-dimensional data of the evaluated system, and rich and convenient data support is provided for fault information retrieval matc
