Computer-implemented method, system, and storage medium
First Claim
1. A computer-implemented method comprising:
- acquiring, from a system to be monitored, a plurality of messages output by a plurality of configuration items in the system, each of the plurality of messages including an output time;
referring to the plurality of messages and setting a plurality of configuration item pairs which combine two configuration items among the plurality of configuration items, as target configuration item pairs;
first determining, for each of the plurality of configuration item pairs, a strength of relevancy between the target configuration item pairs based on a first co-occurrence probability which indicates a probability that a message is output from one configuration item of a target configuration item pair within a prescribed time period before or after the output time of a message output from the other configuration item of the target configuration item pair; and
second determining, by a processor, a priority ranking for investigating one or more of the configuration items among the plurality of configuration items other than a certain configuration item based on the strength of relevancy of each of the plurality of configuration item pairs, as a response to an input of an investigation ranking determination instruction which designates the certain configuration item among the plurality of configuration items as an investigation start position.

Abstract
A method includes: acquiring messages output by items in the system, each of messages including an output time; referring to the messages and setting item pairs which combine two items among the items, as target item pairs; determining, for each of the item pairs, a strength of relevancy between the target item pairs based on a co-occurrence probability which indicates that a message is output from one of the target item pair within a prescribed time period before or after the output time of a message output from other of the target item pair; and determining a priority ranking for investigating one or more the items among the items other than a certain item based on the strength of relevancy of each of item pairs, as a response to an input of an investigation ranking determination instruction which designates the certain item among the items as an investigation start position.

14. A system comprising:
-
a memory; and a processor coupled to the memory and configured to; acquire, from a system to be monitored, a plurality of messages output by a plurality of configuration items in the system, each of the plurality of messages including an output time, refer to the plurality of messages and setting a plurality of configuration item pairs which combine two configuration items among the plurality of configuration items, as target configuration item pairs, determine, for each of the plurality of configuration item pairs, a strength of relevancy between the target configuration item pairs based on a first co-occurrence probability which indicates a probability that a message is output from one configuration item of a target configuration item pair within a prescribed time period before or after the output time of a message output from the other configuration item of the target configuration item pair, and determine a priority ranking for investigating one or more of the configuration items among the plurality of configuration items other than a certain configuration item based on the strength of relevancy of each of the plurality of configuration item pairs, as a response to an input of an investigation ranking determination instruction which designates the certain configuration item among the plurality of configuration items as an investigation start position.

15. A non-transitory storage medium storing a program for causing a computer to execute a process, the process comprising:
-
acquiring, from a system to be monitored, a plurality of messages output by a plurality of configuration items in the system, each of the plurality of messages including an output time; referring to the plurality of messages and setting a plurality of configuration item pairs which combine two configuration items among the plurality of configuration items, as target configuration item pairs; first determining, for each of the plurality of configuration item pairs, a strength of relevancy between the target configuration item pairs based on a first co-occurrence probability which indicates a probability that a message is output from one configuration item of a target configuration item pair within a prescribed time period before or after the output time of a message output from the other configuration item of the target configuration item pair; and second determining a priority ranking for investigating one or more of the configuration items among the plurality of configuration items other than a certain configuration item based on the strength of relevancy of each of the plurality of configuration item pairs, as a response to an input of an investigation ranking determination instruction which designates the certain configuration item among the plurality of configuration items as an investigation start position.
