Abstract

A management system outputs catalog data, which has been created based on catalog-source data comprising data showing at least an application of a relevant resource with respect to each of multiple providable resources, and which shows the respective applications of the multiple resources, and receives a selection of a resource to be provided from the multiple resources. The management system provides the selected resource as a provided resource, and determines, based on a performance threshold configured with respect to the application of the provided resource, whether or not a performance measurement value, which relates to the processing performance of a network service using the provided resource and which can be monitored by the management system, is normal.

Claims

the storage device stores catalog-source data comprising data, which shows at least an application of a relevant resource for each of multiple of the providable resources, and

the control device;

(A) outputs catalog data, which has been created based on the catalog-source data and shows respective applications of the multiple resources, and receives a selection of a resource to be provided from the multiple resources;

(B) provides the selected resource as a provided resource; and

(C) based on a performance threshold configured with respect to the application of the provided resource, determines whether or not a measurement value, which relates to a processing performance of the network service that uses the provided resource and which can be monitored by the management system, is normal.

2. A management system according to claim 1, wherein the network service is a business service, which is a combination of multiple network services,

multiple resources in the catalog-source data are grouped together for each resource group, which is a combination of one or more resources, the control device:

in the (B), provides multiple resources included in the selected resource group as the provided resources; and

in the (C), for each of multiple provided resources, determines, based on the performance threshold configured based on the application of the provided resource, whether or not a performance measurement value, which relates to a processing performance of a network service using the provided resource and which can be monitored by the management system, is normal, and

the control device, in a case where there exists among the multiple provided resources the provided resource for which the performance measurement value is abnormal, determines, based on the number of abnormal resources in group, which, from among the multiple provided resources, is the number of provided resources for which the performance measurement value is abnormal, whether a business service failure caused by the processing of the business service using the multiple provided resources has occurred, whether a resource failure caused by an apparatus related to the provision of any of the multiple provided resources has occurred, or whether neither the business service failure nor the resource failure has occurred.

3. A management system according to claim 2, wherein the control device further determines whether a resource failure caused by an apparatus related to the provision of any of the multiple provided resources has occurred, or whether neither the business service failure nor the resource failure has occurred.

4. A management system according to claim 2, wherein, in a case where determination is made that the business service failure has occurred, the control device issues a management program of the business service notification to that effect.

5. A management system according to claim 2, wherein, in a case where determination has been made that the resource failure has occurred, the control device notifies a management program of the resource that the resource failure has occurred.

6. A management system according to claim 2, wherein

the catalog-source data further comprises data showing the configuration of a relevant resource and the performance threshold related to the relevant resource for each of multiple provided resources, and

the control device outputs catalog data showing an application, a configuration, and the performance threshold of each of one or more resources included in each resource group.

7. A management system according to claim 2, wherein the control device determines that the business service failure has occurred in a case where the number of abnormal resources in group is larger than a prescribed value.

8. A management system according to claim 2, wherein the control device determines that the business service failure has occurred in a case where the ratio of the number of abnormal resources in group to the number of resources included in the provided resource group is larger than a prescribed value.

9. A management system according to claim 2, wherein

the resource is a virtual resource to which a physical resource is allocated, and

the control device:

in a case where multiple resource groups are provided, determines with respect to a first resource group of the provided multiple resource groups whether or not there exists a first resource for which the performance measurement value is abnormal, and, in addition, in a case where the number of abnormal resources in group is smaller than a prescribed value and/or the ratio of the number of abnormal resources in group to the number of resources included in the provided resource group is smaller than a prescribed value, whether or not there exists in a resource group different from the first resource group of the provided multiple resource groups a second resource to which a second physical resource is allocated, which is related to the first physical resource allocated to the first resource; and

determines that the resource failure has occurred in a case where the second resource group exists, and, in addition, the performance measurement value for the second resource is also abnormal.

10. A management system according to claim 9, wherein

the computer system comprises multiple storage systems,

the resource is a volume created in accordance with a storage area of the storage system being allocated, and

the control device assumes that the first physical resource and the second physical resource are related in a case where the first physical resource and the second physical resource are storage areas of the same storage system.

11. A management system according to claim 8, wherein the performance measurement value comprises an input/output response time with respect to a volume.

12. A management system according to claim 10, wherein

the computer system comprises multiple storage systems,

the resource is a virtual server to which has been allocated a volume created in accordance with a storage area of the storage system being allocated,

the performance measurement value comprises an input/output response time with respect to a volume, virtual server CPU utilization, and virtual server memory usage, and

the control device assumes that the first physical resource and the second physical resource are related in a case where the first physical resource and the second physical resource are storage areas of the same storage system.

13. A method for managing a computer system, which provides a resource to be used in the provision of a network service, the management method comprising:

(A) outputting catalog data, which has been created based on catalog-source data comprising data showing at least an application of a relevant resource with respect to each of the multiple providable resources, and which shows respective applications of the multiple resources, and receiving a selection of a resource to be provided from the multiple resources;
