Abstract:
1. A storage network performance information collecting and storing method for collecting and storing performance information on resources of a storage network having a network device that is placed between a computer and a storage system for transmission and reception of input/output data, comprising: a performance information collecting step of collecting and storing performance information from collection subject components that are chosen in advance out of resources consisting of the storage network, the storage system, and the computer; a performance dependence relation information collecting step of collecting and storing information on a performance dependence relation between the collection subject components; an application performance deterioration period detecting step of collecting and storing a performance deterioration period of an application executed in the computer; a dependence-relation-during-performance-deterioration detecting step of detecting collection subject components that have been in a performance dependence relation with the application whose performance has been deteriorated during the detected application performance deterioration period; a preservation period setting step of setting a second preservation period longer than a normal preservation period is set for performance information of the collection subject components detected in the dependence-relation-during-performance-deterioration detecting step and setting the normal preservation period for performance information of other resources than the detected components; and a deleting step of deleting performance information that has passed one of the normal preservation period and the second preservation period.
