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

1. A management system, configured to manage a computer system configured to provide a resource to be used to provide virtual or physical machines to a tenant, comprising:

a storage device; and

a control device coupled to the storage device, wherein

the control device is configured to;

(A) output catalog data, which show at least one resource group and a use of the resource group, and receive a selection of one of the at least one resource group;

(B) provide at least a plurality of the virtual machines with the selected resource group to the tenant;

(C) determine whether a measurement value, which relates to a processing performance of a network service processed in the virtual machine provided by the selected resource group and which can be monitored by the management system, is normal or abnormal, and

(D) determine, based on a number of abnormal machines in the resource group, which is the virtual or a physical machine whose measurement value relating to the processing performance is abnormal, whether a network service failure caused by the processing of the network service using the selected resource group has occurred, or whether a resource failure caused by an apparatus providing the selected resource group has occurred,

wherein a threshold value used for determining whether the measurement value is normal is set based on the use in the output catalog data for the selected resource group without requiring information of the network service which is actually processed with the selected resource by the tenant.

2. A management system according to claim 1, wherein

the control device is further configured to determine whether a resource failure caused by an apparatus related to the provision of any of the selected resource groups has occurred, or whether neither the business service failure nor the resource failure has occurred.

3. A management system according to claim 1, wherein

the control device is configured to notify, in a case where determination is made that the business service failure has occurred, a management program of the business service notification to that effect.

4. A management system according to claim 1, wherein

the control device is configured to notify, in a case where determination has been made that the resource failure has occurred, a management program of the resource that the resource failure has occurred.

5. A management system according to claim 1, wherein

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

6. A management system according to claim 1, wherein

the control device is configured to determine that the business service failure has occurred in a case where the number of abnormal virtual or physical machines in the resource groups is larger than a prescribed value.

7. A management system according to claim 1, wherein

the control device is configured to determine that the business service failure has occurred in a case where the ratio of the number of abnormal virtual or physical machines in the resource group to the number of virtual or physical machines provided by the selected resource group is larger than a prescribed value.

8. A management system according to claim 1, wherein

the control device is configured to:

determine with respect to a first resource group whether there exists a first virtual machine whose measurement value is abnormal, and, in addition, in a case where the number of abnormal virtual or physical machines in the first resource group is smaller than a prescribed value and/or the ratio of the number of abnormal virtual or physical machines in the first resource group to the number of virtual or physical machines provided by the first resource group is smaller than a prescribed value, whether there exists in a second resource group different from the first resource group a second virtual machine to which a second physical machine is allocated, which is related to a first physical machine allocated to the first virtual machine; and

determine that the resource failure has occurred in a case where the measurement value for the second virtual machine is also abnormal.

9. A management system according to claim 8, wherein

the computer system comprises multiple storage systems providing volumes and

the control device is configured to recognize that the first physical machine and the second physical machine are related in a case where at least one of the volumes is provided by the same storage system to the first physical machine and the second physical machine.

10. A management system according to claim 7, wherein

the measurement value comprises an input/output response time with respect to a volume.

11. A management system according to claim 9, wherein

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

12. A method for managing a computer system, which is configured to provide a resource to be used to provide virtual or physical machines to a tenant, the management method comprising:

(A) outputting catalog data, which show at least one resource group and a use of the resource group, and receiving a selection of one of the at least one resource group;

(B) providing at least a plurality of the virtual machines with the selected resource group to the tenant;

(C) determining whether a measurement value, which relates to a processing performance of a network service processed in the virtual machine provided by the selected resource group and which can be monitored by the management system, is normal or abnormal, and

(D) determining, based on the number of abnormal machines in the resource group, which is the virtual or a physical machine whose measurement value relating to the processing performance is abnormal, whether a network service failure caused by the processing of the network service using the selected resource group has occurred, or whether a resource failure caused by an apparatus providing the selected resource group has occurred,

wherein a threshold value used for determining whether the measurement value is normal is set based on the use in the output catalog data for the selected resource group without requiring information of the network service which is actually processed with the selected resource by the tenant.

13. A non-transitory computer-readable medium encoded with a computer program, for execution by a computer for managing a computer system, which provides a resource to be used in the provisioning of virtual or physical machines to a tenant, the computer program causing the computer to:

(A) output catalog data, which show at least one resource group and a use of the resource group, and receive a selection of one of the at least one resource group;

(B) provide at least a plurality of the virtual machines with the selected resource group to the tenant;

(C) determine whether a measurement value, which relates to a processing performance of a network service processed in the virtual or physical machine provided by the selected resource group and which can be monitored by the management system, is normal or abnormal, and

(D) determine, based on the number of abnormal machines in the resource group, which is the virtual or a physical machine whose measurement value relates to the processing performance is abnormal, whether a network service failure caused by the processing of the network service using the selected resource group has occurred, or whether a resource failure caused by an apparatus providing the selected resource group has occurred,

wherein a threshold value used for determining whether the measurement value is normal is set based on the use in the output catalog data for the selected resource group without requiring information of the network service which is actually processed with the selected resource by the tenant.
