FAILURE SYMPTOM DETECTION SYSTEM AND FAILURE SYMPTOM DETECTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a failure symptom detection system and a failure symptom detection method with which it is possible to respond early to a failure that occurs at the time of software execution.SOLUTION: The failure symptom detection system comprises: a detection definition creation device 100 for previously creating, as a detection definition, a log used to determine the name of a process monitoring unit that prescribes a range in which to detect a program failure symptom, and determine the presence of a failure symptom; and a log analysis device 200 for acquiring a log outputted each time a software program is executed, and detecting a failure symptom on the basis of the detection definition created for the log by the detection definition creation device 100. The log analysis device 200 detects an error log linked to a program failure and analyzing, on the basis of the detection definition for each process monitoring unit of a program, whether there is an occurrence of a detection log that is expected to occur when an originally normal process is executed, and detecting the case of no occurrence of a detection log as a failure symptom.SELECTED DRAWING: Figure 1
