Embodiment Construction
[0050] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0051] In software-intensive systems, in order to record the operating status of the computer system, programmers often add output statements in the code to generate system logs. System log is a kind of semi-structured text information, which not only contains natural language written by programmers, but also includes machine language to record various states of the system. For example, for the system log: "Connection from 10.10.34.12closed", its natural language part is: "Connection from*closed", and "10.10.34.12" is the machine language part of the log.
[0052] Such as figure 1 As shown, it is a flow chart of an anomaly detection method based on log event graph and correlation mining provided by the embodiment of the present invention, the method mainly includes:
[0053] Step 1. Collect system logs from the computer system, and delete the machin...
