Despite its importance for operating Cloud systems, Cloud monitoring has received limited attention from the research community. In this paper, the authors provide an analysis of Cloud monitoring. More precisely, they discuss the main motivations, basic concepts and definitions, and point out open research issues and future directions for Cloud monitoring. Accurate and fine-grained monitoring activities are required to efficiently operate Cloud Computing platforms and to manage their increasing complexity and security requirements. In literature, there is a large number of works proposing surveys and taxonomies of Cloud Computing in general of Virtualization technologies and of Cloud Security.
