摘要： As an embodiment of the present invention, a network monitoring apparatus includes a combination rule storage section where a combination rule is registered; and the combination rule includes a combination of a plurality of failure event information to be monitored, and new event information to which the combination of the plurality of failure event information is to be changed. In this state, the network monitoring apparatus collects a plurality of failure event information from network apparatuses; extracts, from the plurality of failure event information collected, a combination of a plurality of failure event information detected to occur within a unit time; and collates the combination of the plurality of failure event information extracted with the combination of the plurality of failure event information defined to be monitored in the combination rule. Then, when the combination of the plurality of failure event information extracted matches in content and occurrence sequence with the combination of the plurality of failure event information defined to be monitored in the combination rule, the network monitoring apparatus adds the new event information included in the combination rule to the combination of the plurality of failure event information extracted, or alternatively, replaces the combination of the plurality of failure event information extracted with the new event information.

摘要： To enable more accurate determination of a failure cause event, an event mapping acquiring unit acquires an event mapping file defining a normalized alarm message indicating a normalized alarm content, a resource type indicating an event failure location, an alarm type, and an event type indicating event classification of the alarm in association with one another. An event type conversion unit determines whether input alarm information matches the definition of the event mapping file acquired, when the input alarm information matches the definition, sets the event type to a value defined in the event mapping file, when the input alarm information does not match the definition, sets the event type to the alarm type of alarm information, and registers the event type and the alarm information in association with each other as a failure event in the database.

摘要： In a failure location identification apparatus according to one embodiment, a facility information management unit records therein facility information including positional information of a physical resource, an external factor information management unit records therein external factor information concerning an external factor that possibly becomes a factor that causes a failure in the physical resource, the external factor information including positional information of the external factor, and a facility influence definition management unit records therein information concerning a possible influence of the external factor on the physical resource. A facility influence determination process unit identifies a failure occurrence location at which the failure is estimated to occur in the physical resource, from the facility information that is recorded in the facility information management unit and has positional information corresponding to the positional information of the external factor information, and outputs failure location information including information indicating the identified failure occurrence location, when it is determined that the external factor information recorded in the external factor information management unit influences the physical resource, on a basis of the information recorded in the facility influence definition management unit.
