The present application discloses an aggregation method for storing system operation logs, which comprises the following steps: determining the number of aggregation points according to the aggregation mode, and constructing a circular list of aggregation points according to the number of aggregation points; Performing log aggregation on the aggregation points in the circular list in turn according to the aggregation mode; When cycling to the aggregation point where the log has been aggregated, deleting the operation log of the aggregation point, and aggregating the aggregation point of the deleted operation log. By circulating the log aggregation at the aggregation point of the circular list for log aggregation, performing when the log aggregation point is circulated to the aggregation point where the log aggregation, only the original operation log needs to be deleted, and then the log aggregation is performed, thereby realizing the automatic deletion of the operation log, avoiding the manual operation, and improving the reliability of the storage system. The present application also discloses an aggregation device, a server and a computer-readable storage medium for storing system operation logs, which have the above beneficial effects.
