Patent ID: 8751874

Claim:
A managing apparatus for managing an information processing system including a plurality of components, the managing apparatus comprising: a storing unit configured to store fault co-occurrence information storing the number of detection times that a first message pattern indicating a message group including one or two or more messages received from the information processing system in a predetermined duration is detected when a fault has occurred in the information processing system; a determining unit configured to detect the first message pattern from the one or two or more messages received from the information processing system in the predetermined duration, to read the number of detection times from the fault co-occurrence information stored in the storing unit, to calculate a co-occurrence probability of the fault and the first message pattern based on the number of detection times, and to determine that the fault has occurred when the co-occurrence probability is equal to or higher than a threshold value; and an updating unit configured to create a second message pattern indicating a message group obtained by excluding a message output by a changed component from the first message pattern upon detecting that the component has been changed, and to update the first message pattern stored in the fault co-occurrence information to the second message pattern, wherein the determining unit calculates the co-occurrence probability of the fault and the first message updated by the updating unit.
