Download or read book Workload sensitive Timing Behavior Analysis for Fault Localization in Software Systems written by Matthias Rohr and published by BoD – Books on Demand. This book was released on 2015-02-09 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: Software timing behavior measurements, such as response times, often show high statistical variance. This variance can make the analysis difficult or even threaten the applicability of statistical techniques. This thesis introduces a method for improving the analysis of software response time measurements that show high variance. Our approach can find relations between timing behavior variance and both trace shape information and workload intensity information. This relation is used to provide timing behavior measurements with virtually less variance. This can make timing behavior analysis more robust (e.g., improved confidence and precision) and faster (e.g., less simulation runs and shorter monitoring period). The thesis contributes TracSTA (Trace-Context-Sensitive Timing Behavior Analysis) and WiSTA (Workload-Intensity-Sensitive Timing Behavior Analysis). TracSTA uses trace shape information (i.e., the shape of the control flow corresponding to a software operation execution) and WiSTA uses workload intensity metrics (e.g., the number of concurrent software executions) to create context-specific timing behavior profiles. Both the applicability and effectiveness are evaluated in several case studies and field studies. The evaluation shows a strong relation between timing behavior and the metrics considered by TracSTA and WiSTA. Additionally, a fault localization approach for enterprise software systems is presented as application scenario. It uses the timing behavior data provided by TracSTA and WiSTA for anomaly detection.
Download or read book Model Driven Online Capacity Management for Component Based Software Systems written by André van Hoorn and published by BoD – Books on Demand. This book was released on 2014-10-15 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Capacity management is a core activity when designing and operating distributed software systems. Particularly, enterprise application systems are exposed to highly varying workloads. Employing static capacity management, this leads to unnecessarily high total cost of ownership due to poor resource usage efficiency. This thesis introduces a model-driven online capacity management approach for distributed component-based software systems, called SLAstic. The core contributions of this approach are a) modeling languages to capture relevant architectural information about a controlled software system, b) an architecture-based online capacity management framework based on the common MAPE-K control loop architecture, c) model-driven techniques supporting the automation of the approach, d) architectural runtime reconfiguration operations for controlling a system’s capacity, as well as e) an integration of the Palladio Component Model. A qualitative and quantitative evaluation of the approach is performed by case studies, lab experiments, and simulation.

Download or read book Mining Event Traces from Real time Systems for Anomaly Detection written by Mahmoud Salem and published by . This book was released on 2019 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Real-time systems are a significant class of applications, poised to grow even further as autonomous vehicles and the Internet of Things (IoT) become a reality. The computation and communication tasks of the underlying embedded systems must comply with strict timing and safety requirements as undetected defects in these systems may lead to catastrophic failures. The runtime behavior of these systems is prone to uncertainties arising from dynamic workloads and extra-functional conditions that affect both the software and hardware over the course of their deployment, e.g., unscheduled firmware updates, communication channel saturation, power-saving mode switches, or external malicious attacks. The operation in such unpredictable environments prevents the detection of anomalous behavior using traditional formal modeling and analysis techniques as they generally consider worst-case analysis and tend to be overly conservative. To overcome these limitations, and primarily motivated by the increasing availability of generated traces from real-time embedded systems, this thesis presents TRACMIN - Trace Mining using Arrival Curves - which is an anomaly detection approach that empirically constructs arrival curves from event traces to capture the recurrent behavior and intrinsic features of a given real-time system. The thesis uses TRACMIN to fill the gap between formal analysis techniques of real-time systems and trace mining approaches that lack expressive, human-readable, and scalable methods. The thesis presents definitions, metrics, and tools to employ statistical learning techniques to cluster and classify traces generated from different modes of normal operation versus anomalous traces. Experimenting with multiple datasets from deployed real-time embedded systems facing performance degradation and hardware misconfiguration anomalies demonstrates the feasibility and viability of our approaches on timestamped event traces generated from an industrial real-time operating system. Acknowledging the high computation expense for constructing empirical arrival curves, the thesis provides a rapid algorithm to achieve desirable scalability on lengthy traces paving the way for adoption in research and industry. Finally, the thesis presents a robustness analysis for the arrival curves models by employing theories of demand-bound functions from the scheduling domain. The analysis provides bounds on how much disruption a real-time system modeled using our approach can tolerate before being declared anomalous, which is crucial for specification and certification purposes. In conclusion, TRACMIN combines empirical and theoretical methods to provide a concrete anomaly detection framework that uses robust models of arrival curves scalably constructed from event traces to detect anomalies that affect the recurrent behavior of a real-time system.
