Performance management system, information processing system, and information collecting method in performance management system

An information processing system comprising:

• a performance management system for a storage system including a server on which applications operate, a storage apparatus for managing data, which is to be accessed by the server, in a storage, and a switch for communicatively coupling the server with the storage apparatus, the performance management system being communicatively coupled with the server, the storage apparatus and the switch, and collecting management information used for performance management of the storage system;
• an information collecting part which collects the management information from a plurality of resources existing on input-output paths that couple the respective applications with the storage;
• a collecting method setting part which sets a method of causing the information collecting part to collect the management information from each of the resources;
• a congestion monitor which monitors whether or not congestion occurs due to input-output between the performance management system and the resources for collecting the management information;
• and
• a collecting process controller which controls the information collecting part so that the management information is collected in accordance with the method set by the collecting method setting part,
• wherein the collecting method setting part sets the collecting method in accordance with a first processing method of using different timings to collect the management information for the respective input-output paths.

An information collecting method in a performance management system for a storage system including a server on which applications operate, a storage apparatus for managing data, which is to be accessed by the server, in a storage, and a switch for communicatively coupling the server with the storage apparatus, the performance management system being communicatively coupled with the server, the storage apparatus and the switch, and collecting management information used for performance management of the storage system, the information collecting method executed by the performance management system comprising:

• a first step of collecting the management information from a plurality of resources existing on input-output paths that couple the respective applications with the storage;
• a second step of setting a method of collecting the management information from each of the resources;
• a third step of monitoring whether or not congestion occurs due to input-output between the performance management system and the resources for collecting the management information;
• a fourth step of controlling collection of the management information in accordance with the set method;
• and
• a fifth step of setting the collecting method in accordance with a first processing method of using different timings to collect the management information for the respective input-output paths.
