Abstract

In a storage network including at least a computer system, at least an external storage and at least a network system for communication of input/output data between the computer system and the external storage, a method of collecting the performance data on the network system and the software operated on the network system, in which the range or degree of data collection is automatically adjusted as required based on the performance data collected.

Claims

1. An information processing system, comprising:

a storage subsystem having a plurality of logical volumes;

a computer coupled to the storage subsystem and executing a file system managing a plurality of files associating the plurality of logical volumes, and executing a database program managing a plurality of table spaces associating the plurality of files; and

a management computer coupled to the storage subsystem and the computer and storing performance condition information on each of a plurality of elements, the plurality of elements including the plurality of logical volumes and the plurality of files and the plurality of table spaces, and a relation information between the plurality of elements,

wherein the management computer determines, based on the relation information, a necessity as to whether a time interval for collecting the performance condition information on a certain element to be collected of the plurality of elements is changed or whether the performance condition information is collected or not;

the management computer selects, based on a relation of transmitting and receiving an input/output operation between elements, an element to be collected on a path which traces the relation of transmitting and receiving the input/output operation toward an upstream side which imposes a load on the performance condition and toward a downstream side in which the load is imposed on the performance condition, from an element as an origin which is determined to be necessary to collect;

the management computer further selects, based on the relation of transmitting and receiving the input/output relation, an element to be collected on a path which traces the upstream side and the downstream side based on the relation of transmitting and receiving the input/output operation, from each of the element to be collected on the path as a further origin.

2. The information processing system according to claim 1, wherein the performance condition is related to the number of inputs/outputs per second.

3. The information processing system according to claim 1, wherein the certain element is one of the plurality of table spaces, and the at least one of the plurality of files and at least one of other elements corresponding to the certain element is one of the plurality of logical volumes.

4. The information processing system according to claim 1, wherein the relation information comprises a table space-file relation table, a file-volume relation table and a volume-logical volume-port relation table.

5. The information processing system according to claim 1, wherein the database program further manages a plurality of tables associating the plurality of table spaces and the plurality of elements further includes the plurality of tables.

6. The information processing system according to claim 1, wherein the management computer determines the necessity if a value of a specific performance condition obtained for a certain element exceeds or decreases below a predetermined reference value for the value of the specific performance condition or if a change in the value of the performance condition exceeds or decreases below a predetermined reference value for the change.

7. The information processing system according to claim 1, wherein the upstream side indicates a direction for connecting from the management server to the computer and the downstream side indicates a direction for connecting from the management server to the storage subsystem.

8. The information processing system according to claim 1, wherein an element, as the relation of transmitting and receiving an input/output operation between elements, is selected by transmitting or receiving the input/output operation from or to the element to be determined as the necessary as to whether the time interval for collecting the performance condition information is changed or the performance condition information is collected.

9. The information processing system according to claim 1, wherein, if the management server determines that the necessity is canceled, the management server keeps or further selects the time interval or a frequency for collecting the performance condition information on an element to be determined to be canceled.

10. The information processing system according claim 1, the selected element is further selected based on a specified condition.

11. A method of information processing on a management computer of a system including a storage subsystem having a plurality of logical volumes, a computer coupled to the storage subsystem, and wherein the management computer is coupled to the storage subsystem, the method comprising:

storing performance condition information on each of a plurality of elements, wherein the plurality of elements includes the plurality of logical volumes, a plurality of files, a plurality of table spaces, and a relation information between the plurality of elements;

determining, based on the relation information, a necessity as to whether a time interval for collecting the performance condition information on a certain element to be collected of the plurality of elements is changed or whether the performance condition information is collected or not;

selecting, based on a relation of transmitting and receiving an input/output operation, an element to be collected on a path which traces the relation of transmitting and receiving the input/output operation toward an upstream side which imposes a load on the performance condition and toward a downstream side in which the load is imposed on the performance condition, from an element as an origin which is determined to be necessary to collect; and

selecting, based on the relation of transmitting and receiving the input/output relation, an element to be collected on a path which traces the upstream side and the downstream side based on the relation of transmitting and receiving the input/output operation, from each of the element to be collected on the path as a further origin.

12. The method according to claim 11, wherein the performance condition is related to the number of inputs/outputs per second.

13. The method according to claim 11, wherein the certain element is one of the plurality of table spaces, and the at least one of the plurality of files and at least one of other elements corresponding to the certain element is one of the plurality of logical volumes.

14. The method according to claim 11, wherein the relation information comprises a table space-file relation table, a file-volume relation table and a volume-logical volume-port relation table.

15. The method according to claim 11, wherein the database program further manages a plurality of tables associating the plurality of table spaces and the plurality of elements further includes the plurality of tables.

16. The method according to claim 11, wherein the management computer determines the necessity if a value of a specific performance condition obtained for a certain element exceeds above or decreases below a predetermined reference value for the value of the specific performance condition or if a change in the value of the performance condition exceeds above or decreases below a predetermined reference value for the change.

17. The method according to claim 11, wherein the upstream side indicates a direction for connecting from the management server to the computer and the downstream side indicates a direction for connecting from the management server to the storage subsystem.

18. The method according to claim 11, wherein an element, as the relation of transmitting and receiving an input/output operation between elements, is selected by transmitting or receiving the input/output operation from or to the element to be determined as the necessary as to whether the time interval for collecting the performance condition information is changed or the performance condition information is collected.

19. The method according to claim 11, wherein, if the management server determines that the necessity is canceled, the management server keeps or further selects the time interval or a frequency for collecting the performance condition information on an element to be determined to be canceled.

20. The method according claim 11, the selected element is further selected based on a specified condition.
