Failure analysis support system, failure analysis support method, and computer readable recording medium

A failure analysis support method for supporting a failure analysis for a computer system including a plurality of resources, the failure analysis support method comprising:

• storing, in a management information storage unit, inter-resource relation information indicating a relationship between the plurality of resources, metric base values that are each a base value determined for each metric of the plurality of resources, and metric performance values that are each a measured value of each metric of the plurality of resources at each time point;
• identifying a base point-related resource related to a base point resource that is a base point of the failure analysis by referring to the inter-resource relation information, display the base point resource and the base point-related resource to receive a designation of a bottleneck candidate resource, and calculating a failure analysis period that is a period of time to be subjected to the failure analysis based on a metric performance value of the bottleneck candidate resource and a metric base value corresponding to the metric performance value;
• identifying a bottleneck candidate related resource related to the bottleneck candidate resource by referring to the inter-resource relation information, calculating an evaluation value of the bottleneck candidate related resource based on a metric performance value of the bottleneck candidate related resource and a metric base value corresponding to the metric performance value, and identifying a to-be-displayed bottleneck candidate related resource that is a resource to be displayed from the bottleneck candidate related resource based on the evaluation value;
• and
• displaying a screen with an appearance to show a mutual relationship between display resources including the base point resource, the base point-related resource, the bottleneck candidate resource, and the to-be-displayed bottleneck candidate related resource, and a status of the display resources at each time point in the failure analysis period.

A non-transitory computer-readable recording medium containing a computer program for supporting a failure analysis for a computer system including a plurality of resources, the program causing a computer to execute:

• storing, in a management information storage unit, inter-resource relation information indicating a relationship between the plurality of resources, metric base values that are each a base value determined for each metric of the plurality of resources, and metric performance values that are each a measured value of each metric of the plurality of resources at each time point;
• identifying a base point-related resource related to a base point resource that is a base point of the failure analysis by referring to the inter-resource relation information, display the base point resource and the base point-related resource to receive a designation of a bottleneck candidate resource, and calculating a failure analysis period that is a period of time to be subjected to the failure analysis based on a metric performance value of the bottleneck candidate resource and a metric base value corresponding to the metric performance value;
• identifying a bottleneck candidate related resource related to the bottleneck candidate resource by referring to the inter-resource relation information, calculating an evaluation value of the bottleneck candidate related resource based on a metric performance value of the bottleneck candidate related resource and a metric base value corresponding to the metric performance value, and identifying a to-be-displayed bottleneck candidate related resource that is a resource to be displayed from the bottleneck candidate related resource based on the evaluation value;
• and
• displaying a screen with an appearance to show a mutual relationship between display resources including the base point resource, the base point-related resource, the bottleneck candidate resource, and the to-be-displayed bottleneck candidate related resource, and a status of the display resources at each time point in the failure analysis period.
