  • Publication number: 20210365189
    Abstract: The present invention aims to specify a bottlenecked resource more accurately in an IT system. In a performance analysis apparatus which includes a processing device, a storage device and an input/output interface and analyzes a performance of an IT system, the processing device creates an overall performance prediction model by using a nonlinear regression algorithm with a first overall performance value being set as an objective variable and with a first resource performance value being set as an explanatory variable, creates an explanatory model by inputting the overall performance prediction model and using an XAI technology and calculates a degree of per-resource influence on the overall performance value which is output by inputting a second resource performance value into the explanatory model.

  • Publication number: 20210264375
    Abstract: Prediction of time series data can be performed while coping with a “non-equidistant event,” “extrapolation,” and a “base line shift.” An event regression section calculates event prediction data that is predicted values of metric data in an intended period including a past certain period on the basis of actual measured value data indicating values of the metric data in the past metric data. A correction section calculates, as prediction result data that is a prediction result of the time series data, data obtained by shifting each value of the event prediction data in response to a difference between the actual measured value data and the event prediction data in a same period.

  • Patent number: 10909016
    Abstract: In a system where resources are used in a varying manner, when performances are monitored based on detected past behavior when the system was operating normally, if performance behavior is detected that is different, it is difficult to determine whether the detected performance behavior results from resources being used differently than when the system was operating normally. According to the present invention, monitoring accuracy is improved by determining whether performance behavior results from change in characteristics relating to the usage of the system by using means for measuring performances when the system is in operation and detecting a performance different from when the system was operating normally, means for measuring characteristics relating to the usage of the system and detecting whether the characteristics are different from when the system was operating normally, and means for comparing performance information with characteristic information relating to the usage of the system.

  • Patent number: 10904159
    Abstract: It is necessary to allocate sufficient surplus resources to each service in order to maintain a service level of each service, but, as a result, many resources which are not used may be necessary. A resource allocation optimizing system performs, with respect to each of a plurality of services, a predictive judgement which is a determination of whether or not accurate prediction of a workload of the service is able to be anticipated, and controls allocation of a resource to the service on the basis of a result of the predictive judgement. With respect to each service, the predictive judgement is performed on the basis of at least one of (x) time-series measured workloads and time-series predicted workloads in a predefined period for the service and (y) at least one of a measured service level and a predicted service level in the predefined period for the service.

  • Patent number: 10235005
    Abstract: Pursuant to the increase in the number of objects to be managed and the complication of relations of the objects to be managed, the current condition is that the visibility of the GUI of management software is deteriorating. As one such current condition, there is a problem in that the display name of equipment to be managed on the GUI cannot be entirely displayed depending on the screen. Thus, the present invention improves the readability on the GUI by changing the display name according to the objective of the administrator by using a label in which the display name is divided into morphemes and the priority assigned thereto, as well as using topology information, and fitting the display name within the display area prepared on the screen.
