SYSTEM PERFORMANCE ANALYZER, SYSTEM PERFORMANCE ANALYSIS METHOD AND SYSTEM PERFORMANCE ANALYSIS PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a technique which enables efficient performance analysis about functions in a system, for each session including a plurality of transactions.SOLUTION: A system performance analyzer 10 performs the following processes: a process to read a function log 105 from a system 20 to be analyzed and acquire each piece of identification information of a function which each transaction plays and a session to which the transaction belongs to store it in a database 106; a process to read a system log 108 from the system 20 to be analyzed, separately identify a record in which identification information of the transaction matches between the system log 108 and the database 106 and generate a file 109 by adding each piece of identification information of the function and the session included in the identified record in the database 106 to the identified record in the system log 108 to store it in a storage unit 11; and a process to read a plurality of files 109 whose identification information of the session and the function is common from the storage unit 11 and perform performance analysis for each session of the function on the basis of data of the system log included in the files.
