Towards semantic monitoring data collection and representation in federated infrastructures
The federation of infrastructures in the fields of Cloud and Future Internet (FI) test beds is evolving rapidly due to its multilateral benefits for end-users and infrastructure owners. However, interoperable monitoring data exchange across multiple administrative domains is a critical task to achieve as the heterogeneity of the used tools and interfaces arises. Several efforts have been done to unify interfaces but are task or domain specific. In this paper alternative, existing data models and collection protocols are reviewed. Their limitations to serve the need of a generic monitoring solution operating across federated, heterogeneous infrastructure are identified. This paper introduces an approach for unification of monitoring data collection and representation based on Semantic Web technologies. The main contribution of this paper is the design and implementation of an ontology-based information model for monitoring federated infrastructures. An initial validation has been achieved in a local cloud test bed, however, this solution is planned for a federation of multiple heterogeneous test beds within the context of the European Fed4FIRE project.
