Claim 0:
1. An operation management apparatus comprising:
at least one memory configured to store:
instructions;
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; and

at least one processor configured to execute the instructions to:
receive at least one designation of the service definition information corresponding to an interrupted service, from among the plurality of pieces of service definition information;
specify, 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;
specify, 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, specify 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
generate output information indicating a failure probability based on the specified timeout value for the via-apparatus.
