The present disclosure relates to a method and apparatus for troubleshooting based on log similarity. In one embodiment, there is provided a method for troubleshooting based on log similarity, comprising: extracting log patterns from multiple log files in response to having collected the multiple log files from at least one system with troubles, the log pattern describing a regular expression to which a log message in a log file among the multiple log files conforms; building a pattern repository using the log patterns; mapping each of the multiple log files to an n-dimensional vector based on the pattern repository; and clustering multiple n-dimensional vectors to which each of the multiple log files is mapped into at least one group, wherein each of the at least one group indicates one trouble type of the at least one system. In another embodiment, there is provided a corresponding apparatus.
A method for troubleshooting based on log similarity, the method comprising:
An apparatus for troubleshooting based on log similarity, comprising:
The apparatus according to claim 13, wherein the extracting module is further configured to:
The apparatus according to claim 14, wherein the extracting module is further configured to:
The apparatus according to claim 17, wherein the eigenvalue tfidfi,j is associated with the term frequency tfi,j of the log pattern pi and with the inverse document frequency idfi of the log pattern pi.
Dependencies are inferred from the claim text.
