Classification: CPC G  H | IPC G

Claim 3:
4. An operation management method comprising:
storing, by a computer:
a plurality of pieces of communication path information each associating a system element of a communication source, a system element of a communication destination, a via-apparatus, and a timeout value in the system element of the communication source with each other; and
a plurality of pieces of service definition information each associating a service and some of the plurality of pieces of communication path information,
wherein the timeout value indicates a threshold of a waiting time of a communication response that is allowable in the system element of the communication source;

receiving, by the computer, at least one designation of the service definition information corresponding to an interrupted service, from among the plurality of pieces of service definition information;
specifying, by the computer, some of the plurality of pieces of communication path information included in the designated service definition information as a plurality of pieces of specific communication path information;
specifying, by the computer and with respect to each of the plurality of pieces of specific communication path information, the via-apparatus, the system element of the communication destination, and the timeout value;
when a same via-apparatus is specified for two or more of the plurality of pieces of specific communication path information, specifying, by the computer, a shorter timeout value among the timeout values in the system elements of the communication source defined in the two or more of the plurality of pieces of specific communication path information; and
generating, by the computer, output information indicating a failure probability based on the specified timeout value for the via-apparatus.
