Method and program of collecting performance data for storage network

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.

1 . A displaying method in a management computer: coupled to a computer, a storage system and a switch device, the switch device being coupled to the computer and the storage system, the displaying method comprising the steps of: 
 storing relation information including a first relation among a first port of the computer, a second port of the switch device and a third port of the storage system, the first, second and third ports being used by the computer to send data to the storage system;    collecting performance information of the first port, the second port and the third port; and    displaying the performance information of the first, the second and the third ports with a physical correspondence among the computer, the switch and the storage system by using the relation information.    
   
   
       2 . A displaying method according to  claim 1 , 
 wherein the relation information further includes a second relation between the first relation and a volume included in the storage system,    wherein in the collecting step, performance information of the volume is collected by the management computer, and    wherein in the displaying step, the performance information of the volume is displayed with the physical correspondence among the computer, the switch and the storage system by using the relation information.    
   
   
       3 . A displaying method according to  claim 1 , 
 wherein the performance information of the first, second and third ports are displayed on a graph.    
   
   
       4 . A displaying method according to  claim 1 , 
 wherein the performance information includes temporal changes of performance of the first, second and third ports.
