Management system for managing computer system

A management method comprising:

• by a management system of a computer system including a plurality of components, detecting occurrence of an event which occurs at at least one of the plurality of components, and which belongs to an event type defined as an event type for which display of performance data is to be requested in the future, and, in the case where performance data to be displayed among performance data of the plurality of components is not stored in a memory of the management system, the management system reading the performance data to be displayed from a performance store which is a store in which the performance data of the plurality of components is stored to the memory of the management system of the computer system and displaying the performance data, wherein each piece of the performance data includes time and a performance value,
• the management system storing event history information which is information indicating time at which the event belonging to the event type occurs and a component where the event occurs, and
• in the case where the event is detected,
• (A) selecting at least one of relevant components of an event component as a read-ahead target, the event component being a component where the event occurs, and the relevant components being components directly or indirectly coupled to the event component,
• (a1) specify change time which is time at which tendency of the performance value changes by equal to or larger than a predetermined degree based on time-series performance data of the event component, and
• (a2) specify a relevant component where the event belonging to the event type occurs in a time slot based on the change time among the relevant components based on the event history management information,
• the relevant component selected as the read-ahead target in (A) being at least one of the components specified in (a2), and
• (B) in addition to performance data of the event component, reading performance data of the selected relevant component from the performance store to the memory.

A non-transitory computer-readable storage medium storing a computer program executed at a management system of a computer system including a plurality of components,

• in the case where performance data to be displayed among performance data of the plurality of components is not stored in a memory of the management system, the management system reading the performance data to be displayed from a performance store which is a store in which the performance data of the plurality of components is stored to the memory of the management system of the computer system and displaying the performance data to be displayed, wherein each piece of the performance data includes time and a performance value, the computer program causing the management system to:
• detect occurrence of an event which occurs at at least one of the plurality of components, and which belongs to an event type defined as an event type for which display of performance data is to be requested in the future;
• store event history information which is information indicating time at which the event belonging to the event type occurs and a component where the event occurs;
• in the case where the event is detected,
• (A) select at least one of relevant components of an event component as a read-ahead target, the event component being a component where the event occurs, and the relevant components being components directly or indirectly coupled to the event component,
• (a1) specify change time which is time at which tendency of the performance value changes by equal to or larger than a predetermined degree based on time-series performance data of the event component, and
• (a2) specify a relevant component where the event belonging to the event type occurs in a time slot based on the change time among the relevant components based on the event history management information,
• the relevant component selected as the read-ahead target in (A) being at least one of the components specified in (a2);
• and
• (B) in addition to performance data of the event component, read performance data of the selected relevant component from the performance store to the memory.
