Host fault detection method and device, electronic equipment and storage medium

The invention discloses a host fault detection method and device, electronic equipment and a storage medium. Comprising the following steps: determining a target host with a performance fault currently, and obtaining an index data sequence corresponding to each performance index of the target host; calculating the dynamic causal strength between every two performance indexes by using the index data sequences of every two performance indexes, and constructing a performance index group based on the two performance indexes of which the dynamic causal strength is greater than a preset threshold value; obtaining direction indications between target performance indexes in the performance index group; and constructing an index association diagram of the target host based on the direction indication and the performance index group, and visually displaying the index association diagram. According to the method, the causal analysis is performed on the performance indexes through the dynamic causal strength of the index
