Abstract

A method for estimating a candidate cause in a failure occurred in an information processing apparatus by a computer, the method includes retrieving, by the computer, a first set of incident information from a data storage region on the basis of failure symptom data which is set on the computer, the data storage region storing incident information, each piece of the incident information including failure symptom data, first cause data of a positive judgment result of a cause in the failure, and second cause data of a negative judgment result of the cause in the failure, each of the first set including the failure symptom data identical to the set failure symptom data.

Claims

1. A method of estimating a candidate cause in a failure occurred in an information processing apparatus by a computer, the method comprising:

retrieving, by the computer, a first set of incident information from a data storage region on the basis of failure symptom data which is set on the computer, the data storage region storing incident information, each piece of incident information including failure symptom data, first cause data of a positive judgment result of a cause in the failure, and second cause data of a negative judgment result of the cause in the failure, each of the first set including failure symptom data identical to the set failure symptom data;

extracting, by the computer, a second set of incident information from the first set on the basis of cause data which is set on the computer, each piece of the second set including the second cause data identical to the set cause data; and

outputting, by the computer, the first cause data included in the second set as candidate cause data.

2. The method according to claim 1, further comprising:

storing in the data storage region, by the computer, the set failure symptom data, the first cause data and the second cause data of the second set as a piece of incident information.

3. The method according to claim 2, wherein the storing is performed in case that log-in information which is set on the computer matches registered log-in information, log-in information used for specifying a user.

4. The method according to claim 1, wherein the outputting includes outputting a respective number of incident information including identical first cause data.

5. The method according to claim 4, wherein the outputting includes outputting the first cause data in descending orders of respective numbers of incident information.

6. An apparatus for estimating a candidate cause in a failure occurred in an information processing apparatus, the apparatus comprising:

a storage configured to store incident information including failure symptom data, first cause data of a positive judgment result of a cause in the failure, and second cause data of a negative judgment result of the cause in the failure; and

a processor coupled to the storage and configured to;

retrieve a first set of incident information from the storage on the basis of failure symptom data which is set on the estimating apparatus, each of the first set including failure symptom data identical to the set failure symptom data,

extract a second set of incident information from the first set on the basis of cause data which is set on the estimating apparatus, each piece of the second set including the second cause data identical to the set cause data, and

output the first cause data included in the second set as candidate cause data.

7. The apparatus according to claim 6, wherein the processor is configured to store in the storage, the set failure symptom data, the first cause data and the second cause data of the second set as a piece of incident information.

8. The apparatus according to claim 6, wherein when log-in information which is set on the apparatus matches registered log-in information, log-in information used for specifying a user, the processor is configured to store in the storage, the set failure symptom data, the first cause data and the second cause data of the second set as a piece of incident information.

9. The apparatus according to claim 6, wherein the processor is configured to output a respective number of incident information including identical first cause data.

10. The apparatus according to claim 9, wherein the processor is configured to output the first cause data in descending orders of respective numbers of incident information.

11. A computer-readable non-transitory medium storing a program causing a computer to execute a process for estimating a candidate cause in a failure occurred in an information processing apparatus the process comprising:

retrieving a first set of incident information from a data storage region on the basis of failure symptom data which is set on the computer, the data storage region storing incident information, each piece of incident information including failure symptom data, first cause data of a positive judgment result of a cause in the failure, and second cause data of a negative judgment result of cause in the failure, each of the first set including failure symptom data identical to the set failure symptom data;

extracting a second set of incident information from the first set on the basis of cause data which is set on the computer, each piece of the second set including the second cause data identical to the set cause data; and

outputting the first cause data included in the second set as candidate cause data.

12. The computer-readable non-transitory medium according to claim 11, the process further comprising:

storing in the data storage region, the set failure symptom data, the first cause data and the second cause data of the second set as a piece of incident information.

13. The computer-readable non-transitory medium according to claim 12, wherein the storing is performed in case that log-in information which is set on the computer matches registered log-in information, log-in information used for specifying a user.

14. The computer-readable non-transitory medium according to claim 11, wherein the outputting includes outputting a respective number of incident information including identical first cause data.

15. The computer-readable non-transitory medium according to claim 14, wherein the outputting includes outputting the first cause data in descending orders of respective numbers of incident information.
