Abstract:
1. A non-transitory computer-readable recording medium storing a system analysis program containing instructions executable on a computer, the program causing the computer to execute: a data observation procedure for observing data which has elements constituting messages communicated on an analysis target system; a message reconstruction procedure for, if the observation of said data has partially failed, reconstructing the observed data and the data of which the observation has failed, into rules containing a request and a response which are communicated on the system; a message candidate extraction procedure for comparing said message rules in which contents of said messages have been defined, with the reconstructed messages, and extracting messages from said message rules which are identical to said reconstructed messages, from the messages defined in said message rules, as message candidates; a call relationship extraction procedure for extracting a call relationship between said message candidates; and a matching procedure for comparing transaction models in which processes in units of transactions on said system have been modeled based on call relationships among the processes on said system, with said extracted call relationship, and selecting and determining a transaction model identical to said call relationship.
