Abstract: A communication monitor includes a path change determining unit that generates path change information including a path change at the time of the path change in a network and an alarm at the time of the path change, and a collecting unit that collects traffic information of each path in the network. The communication monitor further includes an evaluating unit that calculates a degree of coincidence of traffic information representing a degree by which traffic information at the time of the current path change coincides with previous traffic information in the path change information immediately before the path change. The communication monitor further includes a predicting unit that predicts an alarm of the path change information related to the previous traffic information as an alarm at the time of the current path change when the degree of coincidence of the traffic information exceeds an alarm threshold value.
