  • Publication number: 20220066842
    Abstract: Provided are an event monitoring apparatus and an event monitoring method that make it possible to set a proper threshold without handling monitoring target systems on an individual basis. There are included: a threshold determination program calculating degree of similarity between a ledger guide message and an event message, regarding a maximum value of the calculated degree of similarity as a first threshold, and setting a second threshold that is greater than the first threshold by a predetermined value; a ledger allocation program associating a ledger guide message having the degree of similarity intermediate between the first threshold and the second threshold with the event message; and a threshold evaluation program reporting the degree of similarity to a manager of a monitoring target system when the degree of similarity is higher than the first threshold.

  • 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.

  • Publication number: 20150280987
    Abstract: In a multi-tenant information processing system, when initially constructing a tenant, design items depending on the tenant are specified for each device constituting the tenant, and design values of the design items are calculated without overlapping with those of other tenants. In a tenant design item management table, the design items set for the devices and information indicating whether the design items depend on the tenant, are stored for each device. In a design algorithm management table, calculation formulae for making the design values to be different for each tenant are stored corresponding to the design items. A tenant design unit refers to the tenant design item management table, specifies the design items depending on the tenant among those corresponding to the devices constituting the tenant, calculates the design values of the design items according to the calculation formula, when initially constructing the tenant.
