Failure log collection device, failure log collection method, and failure log collection program

摘要

PROBLEM TO BE SOLVED: To provide a failure log collection device which, when failure occurs in a system, surely collects failure logs of all devices in the system and also collects failure logs of the maximum amount of information.SOLUTION: A failure log collection device comprises processing processors and a diagnostic processor. Each of the processing processors is configured to: save information about its internal state in such a manner that a part of the internal state information can be collected from the outside; when occurrence of failure is detected, collect the internal state information as first log information in order to output the first log information and failure occurrence information which indicates occurrence of the failure; and when the failure occurrence information is received from the outside, collect the first log information in order to output the first log information. When the diagnostic processor receives the failure occurrence information and any of the processing processors cannot collect the first log information, the diagnostic processor is configured to collect a part of the internal state information from the outside of the processing processor as second log information.
