Abstract: Monitoring apparatus is configured to execute: obtaining pieces of information about access in a first time slot by specifying the first time slot including access to a first apparatus in the system where a response time is long; selecting a feature common to the access in the first time slot from the pieces of information about the access in the first time slot that have been obtained; first extracting from pieces of information about access in a given period of time, pieces of information about access that has the common feature selected as a feature common to the access in the first time slot; and first generating a first graph which shows changes with time in response time, based on the pieces of information about the access having the feature common to the access in the first time slot that have been extracted.

Abstract: A storage system includes a plurality of storage systems and an analysis server. The analysis server analyzes and outputs an information of a storage system to another storage system based on information of the storage system and information of the other storage system which cooperates with the storage system.

Abstract: A resource allocation system calculates a performance ratio and a cost for each of a plurality of service tiers. For each of the service tiers, the performance ratio is a ratio of the intended performance to an agreement performance, the agreement performance is a performance that serves as a reference performance of the service tier, the intended performance is a performance calculated for the service tier, and the cost is based on a used capacity of an allocated storage resource among the storage resources belonging to the service tier. The system displays a service tier map that has an axis corresponding to the performance ratio and a second axis orthogonal to the axis and corresponding to the cost. A display object is placed, for each service tier, at a position according to the calculated performance ratio and the calculated cost of the service tier on the service tier map.

Abstract: A scaling system ranges over a first base in which a first calculating apparatus having first and second worker nodes operates, and a second base in which a storage apparatus connected to the first base by a network is set. The storage apparatus includes first and second network ports, and first and second volumes accessed by first and second worker node, respectively. A second calculating apparatus is further set in the first base, and the second worker node is moved to the second calculating apparatus and operates as a third worker node and the second volume communicates with the third worker node through the second network port if the transfer rate of the first calculating apparatus or the transfer rate of the first network port exceeds a predetermined threshold when the first and second volumes are in communication with the first calculating apparatus through the first network port.

Abstract: To reduce a risk of detecting an access within a range of temporarily elevated access authority as an unauthorized access, an unauthorized access detection device stores elevated access management data related to an elevated access operation (an operation within a range of temporarily elevated access authority) performed on a system. An operation log source that is a source of an operation log is configured to accumulate operation logs of operations as the elevated access operation on the system, as well as operation logs of operations other than the elevated access operation. The unauthorized access detection device acquires an operation history (one or more operation logs) from the operation log source, and performs determination on whether a response is required that is a determination on whether an operation identified from the operation history is an operation as an unauthorized access not matching an operation identified from the elevated access management data.

Abstract: An operation assistance system receives selection of a first procedure in a procedure manual including a plurality of procedures relating to an operation of an operation target. The operation assistance system displays an estimation structure obtained by structuring at least part of the first procedure based on an abstraction structure obtained by structuring a second abstraction procedure included in a first abstraction procedure corresponding to the first procedure and the selected first procedure.

Abstract: A response time of an access to an application is monitored, and, when a trouble may occur, an alert is given to an administrator to reduce a workload on the administrator. A response time of the application is measured, a request in which the response time exceeds a reference value is extracted, and exceeding requests are aggregated in units of predetermined time widths. An interval between adjacent time bands in which the exceeding requests are present is calculated to determine a periodical tendency of occurrence of exceeding. An alert having a level depending on the tendency is output.
