We view the problem of flexible and adaptive processing of distributed data streams as a grid computing problem. We have been developing a middleware for processing of distributed data streams. Our system is referred to as GATES (grid-based adaptive execution on streams). It is designed to use the existing grid standards and tools to the extent possible. Because of the real-time requirements, there is a need for adapting the processing in such a distributed environment, and achieving the best accuracy of the results within the real-time constraint. For this purpose, our system flexibly achieves the best accuracy that is possible while maintaining the real-time constraint on the analysis. We have developed and implemented a self-adaptation algorithm. This paper focuses on describing and evaluating this algorithm.","PeriodicalId":345031,"journal":{"name":"International Conference on Autonomic Computing, 2004.

We record runtime properties of each request and apply automated machine learning and data mining techniques to identify the causes of failures. We train decision trees on the request traces from time periods in which user-visible failures are present. Paths through the tree are ranked according to their degree of correlation with failure, and nodes are merged according to the observed partial order of system components. We evaluate this approach using actual failures from eBay, and find that, among hundreds of potential causes, the algorithm successfully identifies 13 out of 14 true causes of failure, along with 2 false positives. We discuss some results in applying simplified decision trees on eBay's production site for several months. In addition, we give a cost-benefit analysis of manual vs. automated diagnosis systems. Our contributions include the statistical learning approach, the adaptation of decision trees to the context of failure diagnosis, and the deployment and evaluation of our tools on a high-volume production service.","PeriodicalId":345031,"journal":{"name":"International Conference on Autonomic Computing, 2004.

Fontana","doi":"10.1109/ICAC.2004.59","DOIUrl":"https://doi.org/10.1109/ICAC.2004.59","url":null,"abstract":"The Component Balancer establishes and maintains response time goals for selected business logic contained in methods in component-based applications without the need to modify application code. The premise for this optimization is that meaningful business logic in component methods can be driven to response time goals by controlling the calling rate of other methods. For example, if two methods are accessing the same database, one method's response time can be improved if the other method is selected to withstand longer delays.","PeriodicalId":345031,"journal":{"name":"International Conference on Autonomic Computing, 2004.
