MANAGEMENT SYSTEM, STORAGE SYSTEM, AND MANAGEMENT PROCESSING METHOD

1 . A management system that performs an analysis process of analyzing performance data indicating an operation status of a storage apparatus that stores data,

the management system comprising a processor,

wherein the processor executes

a collection process of repeatedly collecting management information related to the storage apparatus and including the performance data and storing the performance data in a temporary storage area,

an importance level determination process of analyzing the management information and determining an importance level indicating a degree of an influence of the performance data stored in the temporary storage area on the analysis process, and

a migration process of migrating the performance data stored in the temporary storage area to one of a plurality of long-term storage areas having different characteristics based on the importance level.

2 . The management system according to claim 1 , wherein

the long-term storage area includes a first storage area and a second storage area having lower performance than the first storage area,

the importance level is one of a first importance level and a second importance level having a lower degree of the influence than the first importance level, and

the processor migrates the performance data of the first importance level to the first storage area and migrates the performance data of the second importance level to the second storage area in the migration process.

3 . The management system according to claim 2 , wherein the processor generates summary information in which a content of the performance data of the second importance level is summarized and stores the summary information in the first storage area in the migration process.

4 . The management system according to claim 2 , wherein

the processor

executes a device monitoring process of detecting occurrence of an event in the storage apparatus based on the performance data stored in the temporary storage area, and

determines the importance level of the performance data based on a processing result of the device monitoring process in the importance level determination process.

5 . The management system according to claim 4 , wherein the processor sets the importance level of the performance data corresponding to a target period including occurrence date and time of the event as the first importance level in the importance level determination process.

6 . The management system according to claim 2 , wherein the processor sets the importance level of the performance data included in the management information collected last as the first importance level when the management information is not collected for a certain period in the importance level determination process.

7 . The management system according to claim 2 , wherein

the performance data is provided for each resource related to the storage apparatus,

the management information includes manipulation history information indicating a history of a manipulation related to the resource, and

the processor sets the importance level of the performance data corresponding to the resource according to the manipulation as the first importance level in the importance level determination process.

8 . The management system according to claim 2 , wherein

the performance data is provided for each resource related to the storage apparatus, and

the processor sets an importance level of a related resource related to manipulation resource corresponding to the performance data for which the importance level is determined to be the first importance level as the first importance level in the importance level determination process.

9 . The management system according to claim 8 , wherein

the storage apparatus forms a pair with another storage apparatus to which the data is to be copied, and

the related resource includes a resource of the other storage apparatus forming the pair.

10 . The management system according to claim 1 , wherein

the processor executes

a reference process of reading the performance data according to a reference request from the temporary storage area and the long-term storage area and providing the performance data to a request source of the reference request when the reference request for the performance data is received, and

a review process of migrating the performance data stored in the long-term storage area to another long-term storage area based on the reference request.

11 . A storage system comprising:

the management system according to claim 1 ; and

the storage apparatus.

12 . A management processing method executed by a management system that performs an analysis process of analyzing performance data indicating an operation status of a storage apparatus that stores data,

the management processing method comprising:

repeatedly collecting management information related to the storage apparatus and including the performance data indicating the operation status of the storage apparatus and storing the performance data in a temporary storage area;

analyzing the management information and determining an importance level indicating a degree of an influence of the performance data stored in the temporary storage area on the analysis process; and

migrating the performance data stored in the temporary storage area to one of a plurality of long-term storage areas having different characteristics based on the importance level.
