METHOD AND DEVICE FOR CAUSAL ANALYSIS OF CONFIGURATION CHANGES

摘要

A computing system comprises a plurality of target computers and an analysis computer, wherein one or more of a first target computer on which a prescribed application is already installed and running, sends a log which includes information on the plurality of configuration changes which took place before the prescribed application was started to the analysis computer; the analysis computer receives the log and calculates for each type of configuration change the startup failure rate which is the rate at which the prescribed application start has failed after the configuration change, on the basis of the log. Then, a second target computer receives from the analysis computer first information which includes the startup failure rate for each type of configuration change with respect to the prescribed application and shows on the basis of the startup failure rate the type of configuration change which is the cause of the failure of startup of the prescribed application.
