GLIMPSE: a generic and flexible monitoring infrastructure

To respond to the growing needs of evolution and adapta- tion coming from the modern open connected world, appli- cations must continuously monitor their own execution and the surrounding context. The events to be observed, belong- ing to guaranteed functional and non-functional properties, can themselves vary in scope and along time. Therefore the monitor must be easily configurable and able to serve dif- fering event consumers. To address these requirements, we developed the Glimpse monitoring infrastructure conceived having flexibility and generality as main concerns. The pa- per introduces the architecture of Glimpse and shows how it can support runtime performance analysis through a simple example.
