Abstract

The application discloses a method, a system, equipment and a medium for optimizing SSD (solid state disk) log records, and relates to the technical field of solid state disk log management, wherein the method comprises the steps of removing description characters and formatted character strings in an original log printing function, reserving key parameters and adding search fields; the method comprises the steps of printing a simplified log containing search fields and key parameters, establishing a mapping relation among descriptive characters, formatted character strings and the search fields to generate a log search table, analyzing the simplified log through a tool or a script based on the log search table, and restoring real log printing. The application prints only key parameters when printing, and the rest description characters (containing formatted character strings) are omitted, thereby achieving the effect of not compiling the description characters in the compiling stage, reducing the code space of the compiled executable file, reducing the consumption of the log function to the code space, improving the utilization rate of the log space, and realizing compression and restoration of the log without damage.

Description

Method, system, equipment and medium for optimizing SSD log record Technical Field The invention relates to the technical field of solid state disk log management, in particular to a method, a system, equipment and a medium for optimizing SSD log records. Background In an SSD Solid state disk (Solid STATE DRIVE) system, a log is printed at some important processes and abnormal points, especially processes such as abnormal processing. At the same time, journaling is also an important means of analyzing disc problems. However, with the introduction of new characteristics, the complexity of the system is increased, the occupation space of the increased log is multiplied, and as the log is an executable file generated during compiling, especially normally bright characters, including description characters and format character strings, a certain code space needs to be occupied, usually about 15% of the total code space, and the log descriptor can be recorded in the log system by following printing, the normally bright characters occupy about 50% of the total code space, and the log space is squeezed as the system runs for a long time. The method has the problems that firstly constant character strings of a printing function occupy code space, secondly the number of recorded logs is reduced due to the printed constant character strings, log flushing risks exist, and when invalid characters are overlong, the log system limits the length of a single log, and the problem that the printed log is staged is also caused. Description characters are typically shortened by reducing log printing of normally bright strings or limiting the use of log printing functions, but this increases reading difficulty. And limiting log printing, namely, printing is not added in a printing-free process, but whether the printing is reasonably removed cannot be judged, and the log printing containing the positioning information cannot be removed blindly. None of the above methods can fundamentally solve the problems of code space occupation and log space consumption.
