Abstract: A system (200) comprises a plurality of data collectors (210), a correlator (220), a context analyser (230), a baseline analyser (250), a database (260), and a graphical user interface (GUI) (270). The data collectors (210) are deployed on the services or applications that they monitor, or on the network between these applications as a network appliance, and are designed to capture messages that are passed between the various services. The data collectors (210) are non-intrusive, i.e. they do not to impact the behavior of the monitored services. The data collectors (210) can capture messages transmitted using communication protocols including, but not limited to, SOAP, XML, HTTP, JMS, MSMQ, and the like.

Abstract: A method and apparatus that uses application errors as a predictive metric for overall measuring of applications functional health are disclosed. The automated system intercepts messages exchanged between inter-services of enterprise applications, analyzes the context of those messages, and automatically derives application errors embedded in the message. Thereafter, it is capable of showing deviations from expected behavior for the purposes of predicting failures of the monitored application. Furthermore, the invention displays the user's real-time actionable data generated using the application errors.

Abstract: A method and apparatus for detecting abnormal behavior of enterprise software applications is disclosed. A profile that represents the behavior of the function is created for each service and error function integrated in an enterprise software application. This profile is based on input measurements, such as response time, throughput, and non-availability. For each such input measurement, the expected behavior is determined, as well as the upper and lower bounds on that expected behavior. The invention further monitors the behavior of service and error functions and produces an exception if at least one of the upper or lower bounds is violated. The detection scheme disclosed is dynamic, adaptive, and has self-learning capabilities.

Abstract: According to the invention, a data model and method and apparatus for performing content and context modeling are disclosed. The method dynamically classifies and gathers selective information on various monitored systems to detect content related problems and provide context for diagnosing the root cause of these problems. The selected, monitored information for classification is converted to a plurality of dimensions that may be preconfigured, added incrementally after the monitored system is in production, or when a need for more advanced analysis or for wider context arise.

Abstract: A system and a method for automatic verification of complex enterprise software systems, which improves the testing process by producing test scenarios using business process specifications.

Abstract: A World Wide Web site data retrieval system includes an input device for inputting data and commands to access the World Wide Web, and a memory for storing a Web site data retrieval driver which includes a Web reader, stored Web site address information, stored Web site commands, and stored format information. The memory also stores process steps to connect to a Web site and to issue commands within the connected Web site, and a connection to the World Wide Web. The system includes a processor for launching the Web site data retrieval driver in response to a command to access the World Wide Web.

Abstract: Halftoning gray scale image data includes selection of one of plural dither matrices based on an analysis of local tonality gradient for each target pixel. Plural different but reciprocally compatible dither matrices are defined, and for each target pixel in the gray scale image data, a local gradient for tonality is calculated. One of the dither matrices is selected in accordance with the calculated gradient, and the target pixel is thresholded using the selected dither matrix. Enhanced dithering according to the invention improves smoothness of gradations present in the invention, diminishes the "banding" or "contouring" effect found in natural images, and improves visual appearance and stability of business graphics, particularly in cases where a complex image contains both natural and computer generated business graphics.
