Dynamic Dependencies and Performance Improvement (2009)
The art of performance tuning is, alas, still an art; there are few tools to help predict the effects of changes that are motivated by performance needs. In this work, we present dynamic dependency...
Complexity of Composability of Configuration Management (2008)
The explosion of information and integration of technology into everyday life has brought on new demands for how people manage and maintain computer systems. Demand is already outpacing supply when...
Experience Implementing an IP Address Closure (2008)
Most autonomic systems require large amounts of human labor and configuration before they become autonomous. We study the management problem for autonomic systems, and consider the actions needed...
Alva Couch, System Configuration, Federated Configurations, Paul Says
If we have no clear way of stating the required configuration, then we can’t create a tool to implement it! LISA 2004 (2) The configuration problem
Machine Learning for the System Administrator (2008)
In this paper, we explore how some of the principal ideas in machine learning can be applied to the specific task of monitoring computer systems. We show that machine learning can be a valuable tool...
Modelling next generation configuration management tools (2006)
There are several current theoretical models used to discuss configuration management, including aspects, closures, and promises. We examine how these models relate to one another, and develop a...
A.: Autonomic computing approximated by fixed-point promises (2006)
Abstract. We use the concept of promises to develop a service oriented abstraction of the primitive operations that make an autonomic computer system. Convergent behaviour does not depend on...
Understanding One’s Systems: A New Role for Auditing (2006)
Alva Couch, Marc Chiarini, Josh Danziger
Auditing at the kernel level has frequently been used to debug the performance of operating systems and applications [27, 8] or to detect intrusions by finding anomalies in program behavior [20, 16]....
Experience in implementing an http service closure (2004)
Steven Schwartzberg, Bbn Technologies, Alva Couch
One ideal of configuration management is to specify only desired behavior in a high-level language, while an automatic configuration management system assures that behavior on an ongoing basis. We...
On observed reproducibility in network configuration management (2004)
A rigorous language for discussing the issue of configuration management is currently lacking. To this end, we develop a simple state-machine model of configuration management. Observed behaviors...
