Sam Malek, Nels Beckman, Marija Mikic-Rakic, Nenad Medvidovic
2005 Lecture Notes in Computer Science  
However, the lack of the appropriate tools for monitoring, analyzing, and effecting redeployment at the architectural level makes improving a system's deployment architecture a very challenging problem  ...  Dependability is a function of various system parameters, such as network bandwidth, frequencies of software component interactions, power usage, and so on.  ...  Monitor. To determine the run time values of the parameters in the model, a monitor is associated with each parameter.  ...

Incremental Model Synchronization for Efficient Run-Time Monitoring [chapter]

Thomas Vogel, Stefan Neumann, Stephan Hildebrandt, Holger Giese, Basil Becker
2010 Lecture Notes in Computer Science  
Thus, it is attractive to also apply these techniques for autonomic and selfadaptive systems at run-time to enable a comprehensive monitoring of their architectures while reducing development efforts.  ...  This requires special solutions for model transformation techniques as they are applied at run-time instead of their traditional usage at development time.  ...  The core idea of using model transformation techniques for monitoring and even for adaptation of autonomic systems has been presented in [5] , where there was no room for a comprehensive discussion.  ...
