Scalable and Configurable Monitoring System for Cloud Environments

The scale of the current cloud infrastructures and the heterogeneity of applications running on them pose significant challenges about resources management on clouds. This paper proposes a monitoring system that allows user to collect and aggregate data in a form flexible and adequate to the integration with the management policy that he adopt. This monitoring system is supplied by a a configurable and highly scalable version of publisher-subscriber pattern. It gives user the capability of selecting data he should obtain from the provider with the desired grain of triggering and is suitable to support distributed and cooperative management systems.
