Abstract

The invention relates to a log similarity based failure processing method and device. In one implementation mode, the log similarity based failure processing method comprises the steps of making response to acquire multiple log files of at least one system having failures and extracting log modes from the multiple log files, wherein the log modes describe regular expressions corresponding to log messages in the log files in the multiple log files; utilizing the log modes to establish a mode memory bank; mapping each log file in the multiple log files to an n-dimensional vector; clustering multiple n-dimensional vectors where the multiple log files are mapped to at least one group, wherein each group in at least one group indicates one failure type of at least one system. In another implementation mode, the corresponding device is provided. By means of the log similarity based failure processing method and device, manual working amount during failure processing can be reduced.

Description

technical field [0001] Embodiments of the present invention relate to troubleshooting, and more particularly, to methods and apparatus for troubleshooting based on log similarity. Background technique [0002] With the increase in the complexity of computer hardware systems and the enhancement of software system functions, when running on different hardware systems, the operating environment faced by computer systems (including hardware and software, for example) is becoming more and more complex. At this time, the system may appear All sorts of glitches. For example, with the development of multi-core processor technology, more and more computing devices use one or more multi-core processors, which increases the possibility of processor failure; The system may also face other types of failures such as memory leaks. [0003] In various current application systems, there is usually a relatively complete log recording module, which can record various states of the hardware / s...
