The embodiment of the invention discloses a log processing method, an apparatus, a device and a medium. The method comprises the following steps: acquiring log data from at least two functional modules through a log processing module; identifying a function module to which the log data belongs through a log processing module; through the log processing module, the log data being stored differentlyaccording to the function module to which the log data belongs. The technical proposal of the embodiment stores the log data obtained from different functional modules in modules, the invention solves the problems in the prior art that the data range of the log file is large, the content is complex, the logic is unclear, and it is difficult to find and locate the information, and achieves the effect that the log data is stored according to the module classification, the log data is convenient to be retrieved by classification in actual use, the data content of the log file is optimized, and the searching is convenient.
