1. A method of collecting performance data for a system including a computer, a storage system, and a switch device coupled to the computer and the storage system, the method comprising:
- collecting a first performance data from a first element of an access path, used by the computer for accessing from the computer to the storage system via the switch device, the access path including connecting ports of the computer, the storage system and the switch device;
selecting a second element of the access path based on relationship information including a relationship between the connecting ports included in the access path; and
changing a collecting process of a second performance data from the second element of the access path if the first performance data collected from the first element of the access path indicates that a performance condition of the first element is satisfied, in order to determine a cause of the performance condition of the first element.

13. A method of collecting performance data for a system including a computer, a storage system, and a switch device coupled to the computer and the storage system, wherein a relationship information of connecting ports of the computer, switch device and storage system indicates an access path from the computer to the storage system, the method comprising the steps of:
-
collecting first performance data from a first element of the access path; determining if the first performance data indicates that a change in performance of the first element has occurred that satisfies a predetermined condition; if it is determined that the change in performance of the first element does satisfy the predetermined condition, selecting a second element along the access path based on the relationship information and modifying a manner in which second performance data from the second element is collected in order to determine a cause of the change in performance of the first element. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
