The embodiment of the invention discloses a log analysis method and device, computer equipment and a storage medium. The method comprises the steps of in response to a log analysis request, according to service chain identification burying point messages in a log, finding a service chain log message block corresponding to the log analysis request from the log; according to a pre-defined service chain directed graph and reorganization service chain burying point messages in the log, reorganizing the log messages in the service chain log message block, and generating a target service chain directed graph corresponding to the log analysis request; according to a question positioning burying point message in the log, determining a question flow in the target service chain directed graph. According to the log analysis method and device, the computer equipment and the storage medium, based on the service chain directed graph, the service chain identification burying point messages and the burying point message for reorganizing the log and positioning questions, log analysis is implemented in a service scene. For the situation that context scenarios of services are distributed in multiple terminal requests, the analysis process is simplified, and efficient analysis and question positioning are achieved.
