Description

Visual analysis method, medium and device for SSD log Technical Field The invention relates to the technical field of SSD solid state drives, in particular to a visual analysis method, medium and equipment for SSD logs. Background In the running process of an SSD Solid state disk (Solid STATE DRIVE), in order to record the running state of a disk and facilitate problem positioning, the running log of the disk is inevitably required to be recorded, and a common log recording mode is to print a log prefix (including a timestamp, a log level, IO count and the like), a keyword, a key parameter and the like through a printf printing function, and then store the log prefix in a text mode. The main control log system provides corresponding API interface for calling party to print and output log, and the log system outputs the log content to serial port or writes the log content into log down-flushing buffer area. When the log buffer area is full or other brushing trigger conditions are met, the log system brushes the log in the buffer area down to the Nand flash memory for storage, and synchronously records key information such as brushing positions and the like. If the power-down condition occurs, the restarted log system needs to scan log data to recover related parameters, and then reads corresponding log content from the Nand flash memory according to the recovered brushing parameters. When the log is recorded, the key parameters are analyzed according to the formatted character string, and descriptive characters are printed to ensure the uniqueness of the log, so that the process is relatively time-consuming, especially for high-performance SSDs, frequent printing and parameter cyclic analysis consume CPU time, and performance is reduced.
