Abstract: Execution end timing of a jobnet is predicted with stable accuracy. An information processing apparatus executes jobnet execution time prediction model generation processing for generating an execution time prediction model for predicting execution time of a jobnet to be executed on the basis of information associated with execution time of each of previously executed jobnets, a prediction model accuracy determination processing for calculating prediction accuracy for the execution time of each of jobnets by the generated execution time prediction model, and delay determination processing for determining whether to predict execution end timing of a designated jobnet among a jobnet group that is a set of a plurality of jobnets currently being executed or to be subsequently executed on the basis of the execution time prediction model, on the basis of the calculated prediction accuracy for the execution time of each of the jobnets.

Abstract: Provided are an event monitoring apparatus and an event monitoring method that make it possible to set a proper threshold without handling monitoring target systems on an individual basis.
There are included: a threshold determination program calculating degree of similarity between a ledger guide message and an event message, regarding a maximum value of the calculated degree of similarity as a first threshold, and setting a second threshold that is greater than the first threshold by a predetermined value; a ledger allocation program associating a ledger guide message having the degree of similarity intermediate between the first threshold and the second threshold with the event message; and a threshold evaluation program reporting the degree of similarity to a manager of a monitoring target system when the degree of similarity is higher than the first threshold.
