COMPUTER SYSTEM, LOG ANALYSIS METHOD AND LOG ANALYSIS DEVICE

摘要

PROBLEM TO BE SOLVED: To realize an efficient log analysis processing by using limited computer resources in a control system.;SOLUTION: A computer system includes a device for acquiring log data on a monitoring object and a log analysis device for executing log data analysis processing. When receiving a message including a type and an importance level, the log analysis device determines a candidate parameter to identify log analysis processing and log data to be used for the log analysis processing on the basis of the type and the importance level, corrects the candidate parameter on the basis of processing load of the log analysis device so as to execute adjustment processing to determine a parameter for execution, corrects an internal parameter defining contents of processing of the log analysis processing in order to execute the log analysis processing with the parameter for execution, acquires log data on the basis of the parameter for execution and executes the log analysis processing with the acquired log data.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2018,JPO&INPIT
