Abstract

A management computer has a processor configured to: select a service performance name pairing with a received first apparatus performance name; select a performance value of the received first apparatus performance name and a performance value of the selected service performance name; select a threshold of the first apparatus performance name and a threshold of the selected service performance name; determine whether the performance value of the first apparatus performance name exceeds the threshold of the first apparatus performance name within a predetermined period; determine whether the performance value of the service performance name exceeds the threshold of the service performance name within the predetermined period; and when a determination result of the performance value of the first apparatus performance name and a determination result of the performance value of the service performance name are the same result simultaneously, increase evaluation of the threshold of the first apparatus name.

First claim

What is claimed is:

1 . A management computer configured to monitor a system including an apparatus, the management computer comprising:
a storage unit; a processor configured to refer to the storage unit; and an interface for communications to/from the apparatus, wherein: the storage unit is configured to hold: performance information including a performance value of the apparatus and a performance value of a service provided by the system; setting threshold information including a threshold which is used for determining whether or not each of the performance values is abnormal; and service infrastructure performance relationship information including a pair of a service performance name and an apparatus performance name that exhibit correlation in change of performance; and the processor is configured to: select, in the case of receiving a first apparatus performance name for identifying the performance of the apparatus, the service performance name that forms a pair with the received first apparatus performance name from the service infrastructure performance relationship information; select the performance value of the received first apparatus performance name and the performance value of the selected service performance name from the performance information; select the threshold of the first apparatus performance name and the threshold of the selected service performance name from the setting threshold information; determine whether or not the performance value of the first apparatus performance name exceeds the threshold of the first apparatus performance name within a predetermined period; determine whether or not the performance value of the service performance name exceeds the threshold of the service performance name within the predetermined period; evaluate the threshold of the first apparatus performance name so as to increase evaluation of the threshold when a determination result of the performance value of the first apparatus performance name and a determination result of the performance value of the service performance name are the same result simultaneously; and output an evaluation result of the threshold.

2 . The management computer according to claim 1 , wherein:
the storage unit is configured to hold service and I/O relationship information including a pair of the service performance name and an I/O performance name indicating an input/output amount of data of the apparatus, which exhibit correlation in change of performance; and the processor is configured to: select the I/O performance name that forms a pair with the selected service performance name from the service and I/O relationship information; select, from the performance information, the performance value of the selected I/O performance name at a time close to a time indicated by the performance value of the selected service performance name; determine whether or not the performance value of the I/O performance name within the predetermined period is high; and evaluate the threshold of the first apparatus performance name based on the determination result of the performance value of the first apparatus performance name, the determination result of the performance value of the service performance name, and a determination result of the performance value of the I/O performance name.

3 . The management computer according to claim 2 , wherein the processor is configured to:
select all the performance values of the selected I/O performance name from the performance information; and deteimine that the performance value of the I/O performance name within the predetermined period is high in the case where the performance value of the I/O performance name within the predetermined period is included in a predetermined proportion from a top of all the performance values of the selected I/O performance name.

4 . The management computer according to claim 2 , wherein the processor is configured to:
identify a plurality of times at which the performance value of the selected service performance name exceeds the threshold; select the performance values of the I/O performance name at a plurality of times close to the identified plurality of times from the performance information; and deteimine that the performance value of the I/O performance name within the predetermined period is high in the case where the performance value of the I/O performance name within the predetermined period exceeds a mean value of all the performance values of the selected I/O performance name.

5 . The management computer according to claim 2 , wherein the processor is configured to:
select, from the service infrastructure performance relationship information, a second apparatus performance name that forms a pair with the selected service performance name and is different from the first apparatus performance name; select the performance value of the second apparatus performance name from the performance information; select the threshold of the second apparatus performance name from the setting threshold information; determine whether or not the performance value of the second apparatus performance name exceeds the threshold of the second apparatus performance name within the predetermined period; and evaluate the threshold of the first apparatus performance name based on the determination result of the performance value of the first apparatus performance name, the determination result of the performance value of the service performance name, the determination result of the performance value of the I/O performance name, and a determination result of the performance value of the second apparatus performance name.

6 . The management computer according to claim 5 , wherein:
the storage unit is configured to hold threshold evaluation information storing the evaluation result of the threshold of the apparatus performance name; and the processor is configured to: acquire the evaluation result of the threshold of the second apparatus performance name from the threshold evaluation information; and evaluate the threshold of the first apparatus performance name based on the determination result of the performance value of the first apparatus performance name, the determination result of the performance value of the service performance name, the determination result of the performance value of the I/O performance name, the determination result of the performance value of the second apparatus performance name, and the evaluation result of the threshold of the second apparatus performance name.

7 . The management computer according to claim 6 , wherein:
the storage unit is configured to hold exceptional information including a definition of the apparatus performance name that is exceptional in the evaluation of the threshold of the apparatus performance name; and the processor is configured to: refer to the exceptional information to determine whether or not the second apparatus performance name is exceptional; and evaluate the threshold of the first apparatus performance name based on the determination result of the performance value of the first apparatus performance name, the determination result of the performance value of the service performance name, the determination result of the performance value of the I/O performance name, the determination result of the performance value of the second apparatus performance name, the evaluation result of the threshold of the second apparatus performance name, and a determination result indicating whether or not the second apparatus performance name is exceptional.

8 . The management computer according to claim 7 , wherein:
the apparatus included in the system is a storage apparatus; and the exceptional information d
