If the incipience or onset of software aging mechanisms can be reliably detected in advance of performance degradation, corrective actions can be taken to prevent system hangs, or dynamic failover events can be triggered in fault tolerant systems. In the 1990 's the U.S. Dept. of Energy and NASA funded development of an advanced statistical pattern recognition method called the multivariate state estimation technique (MSET) for proactive online detection of dynamic sensor and signal anomalies in nuclear power plants and Space Shuttle Main Engine telemetry data. The present investigation was undertaken to investigate the feasibility and practicability of applying MSET for realtime proactive detection of software aging mechanisms in complex, multiCPU servers. The procedure uses MSET for model based parameter estimation in conjunction with statistical fault detection and Bayesian fault decision processing. A realtime software telemetry harness was designed to continuously sample over 50 performance metrics related to computer system load, throughput, queue lengths, and transaction latencies. A series of fault injection experiments was conducted using a \"memory leak\" injector tool with controllable parasitic resource consumption rates. MSET was able to reliably detect the onset of resource contention problems with high sensitivity and excellent false-alarm avoidance. Spin-off applications of this NASA-funded innovation for business critical eCommerce servers are described.","PeriodicalId":146269,"journal":{"name":"27th Annual NASA Goddard/IEEE Software Engineering Workshop, 2002.

Dynamic interactions and structural embedding, run-time loadable configurations, and services that can be deployed in arbitrary executions environments results in an increased complexity. Moreover, that the variety of possible states and behaviors becomes unpredictable. Thus, since testing during the development phase is always applied in simulated environments, it is almost impossible to detect faults, which appear under real condition, during production phase of a system. We therefore aim at concepts and methodologies that achieve on-line testing of distributed component based systems in their production phase. In comparison with off-line testing (i.e. testing that takes place during system development), on-line testing addresses particular aspects of the behavior of distributed systems, such as: functionality under limited time and resources available, complex transactions that are performed between components provided by different vendors, deployment, and composition of different services.","PeriodicalId":146269,"journal":{"name":"27th Annual NASA Goddard/IEEE Software Engineering Workshop, 2002.

Timely knowledge of what's happening around a soldier can mean the difference between life and death. The goals of an enhanced mobile infantry as expressed in Heinlein's timeless Starship Troopers is becoming a reality today through innovative progress being made by the U.S. Army's 21st Century Land Warrior (LW) program. However, the current system does not provide a \"head up\" display like the capability that today's avionics provides to fighter pilots. What is wanted is that when the soldier employs the weapon he sees objects easily distinguishable as friendly or not, as well as enemy locations. This work is aimed at developing smart icons that are superimposed on the video from a LW weapon sight. Eyekon is an intelligent agent-based decision support system hosted on the LW's wearable computer. Eyekon will use LW networked position reports to provide a perspective view in the weapon sight. This will naturally draw the warrior to the most desirable target. There are many performance and human factors issues to address before the concept can be used in lethal situations.","PeriodicalId":146269,"journal":{"name":"27th Annual NASA Goddard/IEEE Software Engineering Workshop, 2002.
