Log extraction method, log extraction device and storage medium

The invention discloses a log extraction method which comprises the following steps: classifying unmatched log messages, and determining a parent chromosome according to a classification result; carrying out iterative multiplication based on the parent chromosome, wherein the parent chromosome generates a filial generation chromosome through crossover and mutation during iterative multiplication;and after the iteration of a preset number of generations, determining a log extraction template according to the final generation chromosome, and performing log extraction according to the log extraction template. The invention further discloses a log extraction device and a computer-readable storage medium, and the effect of improving the log extraction accuracy is achieved. 本发明公开了一种日志提取方法，包括以下步骤：对未匹配日志消息进行分类，并根据分类结果确定父染色体；基于所述父染色体进行迭代繁衍，其中，所述父染色体在迭代繁衍时通过交叉和变异生成子代染色体；在迭代预设代数后，根据最终代染色体确定日志提取模板，并根据所述日志提取模板进行日志提取。本发明还公开了一种日志提取装置及计算机可读存储介质，达成了提升日志提取的准确性的效果。
