Abstract

A non-transitory computer-readable recording medium has stored therein a program that causes a computer to execute a process including creating a frequent message group based on an appearance frequency of each message included in a message group that is generated in the past, in response to a generation of an error message; extracting, as an error periphery log, a message group within a predetermined time period before and after the error message from an accumulated message group; determining whether or not the error message is included in the frequent message group based on a degree of relation between the error periphery log and the frequent message group; and outputting a message that is not included in the frequent message group in the error periphery log as a related message associated with the error message based on a result of the determining.

First claim

What is claimed is:

1 . A non-transitory computer-readable recording medium having stored therein a program for causing a computer to execute a process, the process comprising:
creating a frequent message group based on an appearance frequency of each message included in a message group that is generated in the past, in response to a generation of an error message; extracting, as an error periphery log, a message group within a predetermined time period before and after the error message from an accumulated message group; determining whether or not the error message is included in the frequent message group based on a degree of relation between the error periphery log and the frequent message group; and outputting a message that is not included in the frequent message group in the error periphery log as a related message associated with the error message based on a result of the determining.

2 . The non-transitory computer-readable recording medium of claim 1 , wherein the process further comprises:
extracting a message group which may not be in the error periphery log as an anomaly message group; outputting the frequent message group as the related message when the error message is included in the frequent message group; and outputting the anomaly message group as the related message when the error message is not included in the frequent message group.

3 . The non-transitory computer-readable recording medium of claim 2 , wherein creating the frequent message group includes:
classifying, into a plurality of different message formats, messages included in an observation message group which is a message group generated in the past, creating an observation data matrix aggregating the number of appearances of each classified message format, and creating the frequent message group from the observation data matrix.

4 . The non-transitory computer-readable recording medium of claim 3 , wherein the extracting the error periphery log includes:
classifying the error periphery log in each of the plurality of different message formats, creating an observation data matrix of an error periphery log aggregating the number of appearances of each classified message format, and wherein the determining whether or not the error message is included in the frequent message group includes: extracting the frequent message group included in the observation data matrix of the error periphery log, extracting the anomaly message group excluding the frequent message group from the observation data matrix of the error periphery log, and determining whether or not the frequent message group is generated in a time zone in which the error message is generated.

5 . The non-transitory computer-readable recording medium of claim 4 , wherein the outputting further includes:
outputting the frequent message group as the related message when the frequent message group is generated in the time zone in which the error message is generated, and outputting the anomaly message group as the related message when the frequent message group is not generated in the time zone in which the error message is generated.

6 . A computer-implemented output method comprising:
creating a frequent message group based on an appearance frequency of each message included in a message group that is generated in the past, in response to a generation of an error message; extracting, as an error periphery log, a message group within a predetermined time period before and after the error message from an accumulated message group; determining whether or not the error message is included in the frequent message group based on a degree of relation between the error periphery log and the frequent message group; and outputting a message that is not included in the frequent message group or in the error periphery log as a related message associated with the error message based on a result of the determining.

7 . An information processing apparatus comprising:
a memory; and a processor, coupled to the memory, configured to: create a frequent message group based on an appearance frequency of each message included in a message group that is generated in the past, in response to a generation of an error message; extract, as an error periphery log, a message group within a predetermined time period before and after the error message from an accumulated message group; determine whether or not the error message is included in the frequent message group based on a degree of relation between the error periphery log and the frequent message group; and output a message that is not included in the frequent message group or in the error periphery log as a related message associated with the error message based on a result of the determining.
