Trace information collecting system and program

Abstract

Occurrence of a failure in a computer system is appropriately detected, and information required for removing the failure is automatically collected. A trace information collecting system of the present invention which collects trace information indicating the course of processing of a program comprises a history recording section for recording a history of run and stop of a target program for which the trace information is to be produced, a similarity calculating section for calculating a degree of similarity between a first operation pattern in which the target program ran and stopped at the last time and a second operation pattern in which the target program ran and stopped at the time before last when the target program, which once stopped, starts to run, a failure occurrence determining section for determining that a failure occurred when the target program ran at the last time on condition that the similarity calculated by the similarity calculating section is lower than a reference similarity, and a trace information collecting section for collecting the trace information from the target program in response to the determination that the failure occurred, wherein the trace information is not collected if it is determined that the failure did not occur.

AI Technical Summary

Benefits of technology

[0014]According to the present invention, the occurrence of the failure in the computer system can be appropriately detected, and the information required for removing or fixing the failure can be automatically collected.

Problems solved by technology

(1) A failure has occurred in the computer system being operated.

Additionally, in order to change the setting of the computer system being operated, approval of a user or an owner should be obtained, which would take much time in many cases.

Therefore, the computer system is not permitted to be stopped for a long time in order to investigate a cause of a failure occurring in the computer system.

Therefore, even if the failure has occurred, the computer system is instantly restarted, and in many cases it is not possible to secure a time for obtaining the approval to acquire the truce information.

Thus, in many cases, it has been difficult to remove the failure from the computer system being operated.

However, in the computer system, unlike the transaction, it is often difficult to determine whether or not a failure has occurred.

On the other hand, in the computer system, a failure often occurs due to composite factors of various modules, and an abnormal operation may occur even if each of the modules is normal.

Furthermore, there may be a case in which processing is interrupted for some operational reason even if an actual failure does not occur.

Thus, it is difficult to determine whether a failure has actually occurred in the computer system and, hence, to determine appropriate timing for producing trace information.
