Abstract
We present a programming model and system support for the development of self-monitoring distributed applications, which sense changes in their networked environment and react by dynamically relocating their components. The monitoring service provides two unique capabilities. First, it enables to perform application-level monitoring, as opposed to only conventional system-level monitoring, without interfering with the basic application logic. Second, it enables dynamic relocation of the monitoring components, in addition to the migration of the monitored components, again, without requiring changes inside application components. The monitoring service and programming model were implemented as a subsystem of FARGO, a programming environment for dynamically-relocatable distributed application. In addition to a programming language interface, relocation can be programmed using a high-level script language, and manually controlled using a graphical tool that tracks component relocations.
