Patent ID: 8751417

Claim:
A computer readable, non-transitory medium having stored therein a trouble pattern creating program, the program causing a computer to execute: (a) extracting, from a plurality of log messages that are output from an information system having a plurality of configuration items and that are output in a predetermined period of time, configuration items that output the log messages; (b) calculating a hop count between the configuration items as a degree of relationship between the configuration items extracted in the (a) extracting; (c) executing learning of the rate of the number of occurrences of troubles in the information system in the number of times the log messages are output, the learning is executed by a number of times which increases as the hop count calculated in the (b) calculating increases and the degree of relationship becomes higher; (d) creating, in accordance with a result of the learning in the (c) executing, a trouble pattern message that is output when a trouble occurs; and (e) calculating, with respect to a combination of configuration items whose degree of relationship calculated in the (b) calculating is equal to or greater than a threshold and using the degree of relationship calculated in the (b) calculating, a weight of each configuration item, wherein the weight of each configuration item uses the hop count between the configuration items.
