Abstract: Disclosed herein is a network management apparatus, comprising: a basic information acquisition unit configured to acquire basic server information including server information and location information, the server information including identification information of an accommodating station accommodating a server that constitutes a network and an identifier of a BMC of the server, the location information indicating an installation location of the server in the accommodating station; a related information generation unit configured to generate server-related information including at least an IP address of the server based on the basic server information; a setting information generation unit configured to generate setting information necessary for provisioning the server based on the basic server information and the server-related information; and a data query unit configured to query the server about normality of the setting information generated by the setting information generation unit.

Abstract: Disclosed herein is a network management apparatus, comprising: a correlating information storage unit configured to store correlating information that correlates an error that may occur when executing a workflow to a way of resolving the error, the workflow defining a series of network construction processes consisting of a plurality of processes; a log collection unit configured to collect logs related to executing the workflow; a workflow stop unit configured to stop executing the workflow when an error occurs during the workflow being executed; an error handling unit configured to, during the workflow being stopped, refer to the correlating information based on the logs and determine a handling dealing with the error to perform the handling; and a workflow resuming unit configured to resume, when the error is resolved by the handling, the workflow from a process corresponding to the handling among the plurality of processes.

Abstract: A credential management apparatus performs a change process, an acquisition process, and a locking process. The change process is processing that periodically changes credential information of components that constitute a network. The acquisition process is processing that acquires maintenance operation information related to a maintenance operation of the network. The locking process is processing that locks the credential information of, among the components, a target component for the maintenance operation not to be changed based on the maintenance operation information, at least during the period while the maintenance operation is being performed.

Abstract: A network management apparatus includes at least one memory configured to store program code; and electric circuitry including at least one processor, the at least one processor being configured to read and operate according to the program code, the electronic circuitry configured to: store configuration information on devices or functions that constitute a virtualized environment of a network; acquire, as property information of the workaround, information associated with one or more devices or one or more functions to which a workaround for a specific hardware or software problem is to be applied; extract the one or more devices or the one or more functions serving as an application target of the workaround by referring to the configuration information based on the property information; and request to execute the workaround with respect to the application target.

Abstract: Disclosed herein is a network management apparatus, comprising: a correlating information storage unit configured to store correlating information, about a failure that occurs, that correlates a notification notified when the failure occurs to a workaround for the failure; a notification acquisition unit configured to acquire, a plurality of notifications notified in relation to a plurality of components related to a device in which the failure has occurred, respectively; a failure determination unit configured to determine whether the failure is a known failure in which the notification is correlated to the workaround or an unknown failure, by referring to the correlating information based on the plurality of notifications; and a workaround determination unit configured to determine, when the failure is determined to be the known failure, the workaround that is correlated to a notification determined according to a predetermined ordering of the components, as the workaround to be applied.
