Abstract: A non-transitory computer readable medium for a real time analysis of a computer system performs a method of describing an occurrence pattern, for which a set of tasks is provided. The tasks are partially repeatedly requested by the system and processed or repeatedly generate events by requests to partial components of the system. An occurrence pattern of the events requesting the tasks or events generated by the task during the real-time analysis is represented by a description of event densities. The description includes a set of elements describing a portion of the occurrence pattern of the events. At least two elements for the description of the part of the occurrence pattern include a further set of elements providing a plurality of hierarchical levels. The further sets and thus the part of the occurrence pattern described by the further sets differ from each other.

Abstract: The invention relates to a method for analyzing, especially in real time, a system, particularly a computer system, which comprises a set of different tasks (?). At least some of the tasks (?n) are requested and processed in a repetitive manner by the system or repeatedly generate requests to partial system components (events). The occurrence pattern of the events that request the tasks or are generated by the task are represented at least in part by a description during the analysis, said description being composed of a set of elements, each of which describes the occurrence pattern of events. The inventive method is characterized that a set of not necessarily uniform elements is used once again with at least two elements for describing the occurrence pattern represented by said at least two elements, while said sets of elements, and thus the occurrence pattern described thereby, are different from each other.
