A system management device manages a monitored system. When a performance failure occurs in the monitored system, the system management device creates a plurality of countermeasures for the performance failure. The system management device evaluates, for each of the plurality of countermeasures, the influence of the countermeasure on the execution of a job having an execution deadline associated with the countermeasure. The system management device selects the countermeasure to be executed on the monitored system from out of the plurality of countermeasures based on the evaluation results.

System management device and system management method

A computer, which is configured to manage a resource for which a metric being an indicator for evaluating performance of the resource is to be measured, the computer being coupled to, via the interface, a management target system including a plurality of resources, and storing correlation information for managing a correlation coefficient indicating a degree of correlation between metrics, and the computer being configured to: detect a trigger event to identify a bottleneck based on a metric value of a monitored metric of a monitored resource; identify a related resource having a coupling relationship with the monitored resource; identify a correlation metric that is highly correlated with the monitored metric from among metrics of the related resource based on the correlation information; identify a combination of the related resource and the correlation metric as a bottleneck candidate.

A management system displays a plurality of elements detected from an information system according to a horizontal relation view (HRV) format which is a multi-column display format, based on information of the plurality of detected elements. In the HRV format display, the plurality of columns correspond to a plurality of types, and include a key column which is a column serving as a key for aggregated display and an aggregation target column subjected to aggregated display according to the key column. The key column includes key objects which represent information on elements belonging to the corresponding type and which are arranged vertically. A lateral area of each of the key objects in the aggregation target column includes aggregation objects indicating aggregation information of elements related to an element represented by the key object, whereby the key objects and the related aggregation objects are arranged on the same row.
