Patent ID: 8682899

Claim:
An apparatus for managing systems each including a plurality of configuration items, the apparatus comprising: a processor to: generate configuration group information by classifying a first plurality of configuration items of a first system into first configuration groups each including one or more configuration items that have outputted messages having a commonality, based on first log information storing messages outputted by the first plurality of configuration items, the configuration group information storing identifier identifying each of the first configuration groups in association with messages outputted by one or more configuration items included in the each of the first configuration groups, generate relation class information that defines, in association with the first configuration groups, first one or more message propagation relations indicating propagation relations of messages outputted by configuration items belonging to the first configuration groups, based on the configuration group information and propagation relations between messages outputted by the first plurality of configuration items, wherein a propagation relation between messages indicates a cause-effect relationship between a pair of configuration items and indicates a propagation of a message in which, within a predetermined period of time since an occurrence of a first event corresponding to a first message that was outputted from a configuration item at a propagation source, a second event derived from the first event at the propagation source occurs at a propagation destination, and, at the same time, a second message regarding the second event is outputted, classify a second plurality of configuration items of a second system into second configuration groups included in the first configuration groups, based on the configuration group information and second log information storing messages outputted by the second plurality of configuration items, and apply second one or more message propagation relations that are associated, by the relation class information, with third configuration groups included in the second configuration groups, to the second plurality of configuration items; and a memory to store the configuration group information and the relation class information.
