Your first time here? Welcome, I'm glad you've dropped in.... David Soul (aka Bricoleur)

In
this powerpoint presentation Gail Kaiser, Janak Parekh, Phillp Gross
and Giussepper Valetto of the Programming Systems Lab of Columbia
University discuss how they are able to retrofit autonomic computing
onto legacy systems.  Their middleware infrastructure is introduced
externally to the target system but utilizes models of the desirable
and undesirable behavior of the system.

The KX architecture they introduce consists of sensors (to collect about the execution); guages (to interpret sensor data by filtering and aggregating the data streams to recognize abstract semantic events); controllers (to determine which semantic events warrant system adaptation); and effectors (to apply reconfigurations, tuning, etc. to individual components of the running system).

Their
event diistiller uses complex temporal event patterns to implement
matching of events across multiple streams/sources.  This event
distiller can trace its conceptual ancestry from David Luckham's
Rapiide and Complex Event Processing. – goto
