System exception reason determination method and device, equipment and storage medium

The invention provides a system exception reason determination method and device, equipment and a storage medium. The method comprises the steps: obtaining the real-time operation and maintenance index data of a to-be-monitored system, obtaining the real-time exception weight value of the real-time operation and maintenance index data according to the historical operation and maintenance index data of the to-be-monitored system, and determining the exception reason of the to-be-monitored system according to the real-time exception weight value; and determining abnormal operation and maintenance index data of the to-be-monitored system, and determining a reason for abnormal operation of the to-be-monitored system according to the abnormal operation and maintenance index data. For only a small number of or occasional request failures, the embodiment of the invention can analyze and determine the specific abnormality reason through the real-time abnormality weight value of the real-time operation and maintenance
