Provided is an information processing system, and the like, with which even if target information that relates to a target of interest has been disguised, such disguising can be more accurately detected, and the appropriate information intended for presentation to a user can be presented according to the detection results. An information processing system is equipped with: a server apparatus which determines whether or not target information is authentic, on the basis of a determination condition and information from which target information relating to a target of interest has been created and which indicates at least a time/date and a first location and a client which controls a presentation unit such that presentation information intended for presentation to a user is presented according to the result of the determination made by the server apparatus.

Monitoring of a state of a system can be accurately performed even when a timing at which a relation changes is different for each set of the metrics. A monitoring apparatusincludes a model storage unitand a determination unit. The model storage unitstores, for each of a plurality of metric sets in a system, a model representing a relation among metrics included in the corresponding metric set. The determination unitdetermines and outputs whether the system is in one state, by comparing a combination of models to which the plurality of metric sets conform respectively when the system is in the one state and a combination of models to which the plurality of metric sets conform respectively when the system is in a state to be determined.

Information processing apparatus, information processing method, and recording medium

Fast classification of data can be performed according to characteristics. In a clustering device (), a data storage unit () stores a plurality of data sets. A cluster generation unit () generates an approximate line that approximates as many data sets as possible within a predetermined margin of error among the plurality of data sets in a space in which the plurality of data sets are arranged in accordance with data values. The cluster generation unit () generates a cluster by classifying the plurality of data sets based on the generated approximate line and outputs the generated cluster.

Information processing device and clustering method

Accuracy of risks defined for abnormalities that might occur in a system is improved. The risk determination deviceincludes a classification unitand a determination unit. The classification unitclassifies abnormal patterns, each representing a relationship among metrics at a time of abnormality detection in a system, into groupsbased on a similarity between the abnormal patterns. The determination unitdetermines, based on the number of abnormal patternsclassified into each of the groups, likelihood of an abnormality of the corresponding group

Information processing device, information processing method, and recording medium

A fault cause extraction apparatus including a storage unit which stores a model including one or more correlation functions between pieces of performance information acquired from a plurality of elements and a correlation-destruction-propagation detecting unit which calculates a degree of influence for each of the elements based on correlation destruction information. The correlation destruction information is calculated based on whether pieces of performance information newly acquired from the elements satisfy a relationship represented by the correlation functions.

Apparatus, method and storage medium for fault cause extraction utilizing performance values

A candidate to cause a fault is identified, in case that correlation destruction is detected in some processing apparatuses or the like due to spread of the fault within a system. A correlation destruction detecting unitdetects correlation destruction related to a correlation which is included in a correlation modelby applying inputted performance value of a monitored object to the correlation modelof the monitored object which a correlation model storing unitstores. The fault analyzing unitdetermines and outputs the monitored object which should be a candidate to cause a fault through comparing results of judging whether detecting or not detecting the correlation destruction related to a common correlation in a plurality of the monitored objects which are connected directly or indirectly with a common apparatus or common the monitored object and which have the correlation modelsincluding the common correlation.

Operations management apparatus, operations management method and program thereof

Performance information which is a possible generation cause of a fault is extracted accurately. A fault cause extraction apparatusincludes a storage unitand a correlation-destruction-propagation detecting unit. Here, the storage unitstores a correlation model including one or more correlation functions, each of which is generated based on a time series of performance information including a plurality of types of performance values in a system and transforms a performance value for one of the types being an input to a performance value for another one of the types being an output. The correlation-destruction-propagation detecting unitcalculates a degree of influence of a performance value for a base point that is one of the types upon the system, based on the number of base point propagation functions, the base point propagation functions being the correlation functions used to transform a performance value for the base point to a performance value for one of other the types being transformable from the base point directly or indirectly and not being input of the correlation function.
