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.
Claims14
An information processing system comprising:
- a storage subsystem having a plurality of logical volumes;
- and
- a computer coupled to the storage subsystem, 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;
- a management computer coupled to the storage subsystem and the computer, 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 manages a plurality of collection time intervals associated with the plurality of elements, collects a performance data of the plurality of elements according to the plurality of collection time intervals, and adds performance values into performance value information based on the collected performance data;
- and
- wherein the management computer selects a certain element from the plurality of elements which satisfies a performance condition based on the performance condition information, selects at least one of the plurality of elements corresponding to the certain element, and modifies a part of the plurality of collection time intervals associated with the certain element and the at least one of the elements corresponding to the certain element.
A management computer for information processing coupled to a computer and a storage subsystem having a plurality of logical volumes, the management computer comprising:
- a storage network management module;
- a processor;
- a memory for 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;
- wherein the management computer is configured to manage a plurality of collection time intervals associated with the plurality of elements, collect performance data of the plurality of elements according to the plurality of collection time intervals, and add performance values into performance value information based on collected performance data;
- and
- wherein the management computer is configured to select a certain element from the plurality of elements which satisfies a performance condition based on performance condition information, select at least one of the plurality of elements corresponding to the certain element, and modify a part of the plurality of collection time intervals associated with the certain element and at least one of the elements corresponding to the certain element.
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 where 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;
- managing a plurality of collection time intervals associated with the plurality of elements;
- collecting performance data of the plurality of elements according to the plurality of collection times intervals;
- adding performance values into performance value information based on the collected performance data;
- selecting a certain element from the plurality of elements which satisfies a performance condition based on the performance condition information;
- selecting at least one of the plurality of elements corresponding to the certain element;
- and
- modifying a part of the plurality of collection time intervals associated with the certain element and the at least one of the elements corresponding to the certain element.
