A network control device includes a network database and a switch controller. The network database stores topology information representing a network, and network flow information representing a data forwarding rule in the network. The switch controller generates the topology information by taking a plurality of switch devices included in the network as nodes and stores the generated topology information in the network database, generates switch flow information that defines an action of each of the plurality of switch devices, based on the network flow information stored in the network database, and sets the switch flow information into a corresponding one of the plurality of switch devices.

Network control device, network control method, and storage medium

An operation management apparatus includes a correlation destruction detection unit and an evaluation value calculation unit. The correlation destruction detection unit detects correlation destruction on a correlation between metrics of two different server among a plurality of servers executed on one or more processing devices in a system. The evaluation value calculation unit calculates and outputs, when correlation destruction on a correlation between two servers has been detected for inputted measurements of metrics, an evaluation value of the correlation destruction on the basis of a relation between the two servers with respect to the correlation on which the correlation destruction has been detected in the system.
