It is provided a resource management server comprising: a resource management module for managing virtual machines and use amounts of resources used by the virtual machines for deployment; a pool management module for managing a total amount of the resources and a total amount of available resources; a requirement specification reception module for receiving an allocation requirement for a new virtual machine along with requirement specifications including amounts of resources; and a search module for searching the virtual machines for deployment included in the resource management information for virtual machines for deployment having amounts of resources that satisfy the requirement specifications, and for virtual machines for deployment which do not have the amounts of resources that satisfy the requirement specifications but which allow the amounts of resources that satisfy the requirement specifications to be secured by adding the available resources included in the pool management information.

Resource management server, resource management method and storage medium for identifying virtual machines satisfying resource requirements

A computer analyzes the root cause of an event, which has occurred in any of multiple management-target apparatuses, based on one or more rules in a storage device, that denote an association between one or more condition events corresponding to one or more events capable of occurring in any of the multiple management-target apparatuses and a conclusion event, which is the cause in a case where the one or more condition events have occurred. The computer, based on an event occurrence log including contents and an occurrence date and time of an event, determines a first event group, which is multiple events presumed to occur as a result of the same cause, creates a new rule in which the multiple events of the first event group are the condition events and one event of the first event group is the conclusion event, and stores the created new rule.

Method and system for supporting event root cause analysis

To analyze the cause if an event occurred to a plurality of monitoring targets. A monitoring computerincludes a general rule storing partconfigured to store a general rule, wherein the general rule previously associates a first event which can occur in any of the plurality of monitoring targets and a second event which can cause the first event, an correlation rule generating partconfigured to generate an correlation rule, wherein the correlation rule is created based on the general rule and configuration information, and in the case where a predetermined number or more of events corresponding to the second events are detected, the correlation rule indicates that an event corresponding to the first event will occur, and an analyzing partconfigured to analyze a cause of an event indicated by the event information based on received event information and the correlation rule.
