Abstract: In analyzing an elaborate computer system which requires large-scale or numerous event propagation models, a law-of-causality matrix gains size, so that significant amount of storage resources has been used in a management computer. To solve such a problem, the management computer to manage the computer system stores topologies, event propagation models, and causality information including one or more causal relations in the storage resources, determines, when the management computer analyzes or detects an event, whether a causal relation has already been created for the event to be analyzed, and creates the causal relation based on a topology and event propagation models, if not yet.

Abstract: A management system manages a computer system including a plurality of types of managed objects. A storage device of the management system stores one or more meta-rules indicating a correspondence relationship between a cause event and one or more influence events, as well as change frequency information indicating a change frequency for each relation between the types of managed objects. A control device of the management system divides, on the basis of the change frequency information, a first relation group indicating a connection configuration within a rule for a first meta-rule, into a second relation group configured by a relation in which a change frequency is equal to or larger than a predetermined value, and a third relation group configured by a relation in which a change frequency is less than a predetermined value, and divides a first meta-rule into a second meta-rule in which the connection configuration indicated by the second relation group is the connection configuration within a rule, and a third meta-rule in which the connection configuration indicated by the third relation group is the connection configuration within a rule.

Abstract: A management system manages a plurality of management target devices. A storage device stores one or more rules, plan information, and plan history information. A control device specifies a first cause event that is a candidate of a cause of the event that has occurred in any one of the management target devices based on the one or more rules, specifies a plurality of first plans that can be executed in the case in which the first cause event is a cause based on the plan information, calculates an index value indicating a possibility of succeeding in a failure recovery in the case in which the plan is executed for each of the plurality of first plans based on the plan history information, and displays data indicating any one or more plans of the plurality of first plans according to a display mode decided based on the index value.

Abstract: There is provided a management computer comprising a processor and a storage resource. The processor acquires information on a type of the first management object and the second management object; traces association from the type of the second management object to the type of the first management object; generates a metarule including a condition part and a conclusion part; generates a method of acquiring information on a topology constructed by the association from the type of the second management object to the type of the first management object based on a method of the trace from the type of the second management object to the type of the first management object; acquires the information on the topology based on the generated method; generates an expanded rule from the generated metarule and the acquired information on the topology; and analyzes a detected new failure based on the generated expanded rule.

Abstract: A distributed ledger system has a configuration in which each of the distributed ledger subsystems includes a sub-ledger that holds ledger data shared in the distributed ledger subsystems, and a smart contract that interlocks between the distributed ledger subsystems having a common sub-ledger to perform a transaction processing related to an input and output of the ledger data, transmits a transaction request targeted for ledger data of another sub-ledger managed by another distributed ledger subsystem to another distributed ledger subsystem having the common sub-ledger by receiving a predetermined transaction request from a predetermined device and executing the smart contract, and replies with a transaction reply obtained from the other distributed ledger subsystem to the predetermined device.

Abstract: Operation management with consistent policies and timings between nodes even in a situation where there are a plurality of administrators in the distributed ledger system is realized. In an operation management system 10 for a distributed ledger system 6 comprising a plurality of nodes, each of at least two or more predetermined nodes in the plurality of nodes manages an operation smart contract 372 for operation management of the distributed ledger system with a distributed ledger 37, when at least one node in the two or more predetermined nodes receives a transaction, the node which has received the transaction judges whether or not a type of the transaction is the operation smart contract 372, and, based on the judgment result, executes the operation smart contract 372.
