A Multi-Level Monitoring Approach for the Dynamic Management of Private IaaS Platforms

To properly implement a dynamic management system in a cloud environment it is imperative to have complete, holistic and up to date information of the environment itself. However, current private cloud IaaS monitoring solutions are not sufficiently evolved to fulfill this task. Such a monitoring system needs to contemplate all stakeholders and dimensions of a cloud environment, while at the same time hiding irrelevant information. We propose an information model that offers a multi-level view of a private IaaS cloud, separates the concerns between consumers and providers, and enables the correlation of the collected data to have a complete picture of the environment. Using it we have designed a monitoring architecture, and built it using agents based on open-source monitoring platforms. We show the feasibility of our approach through two sample scenarios deployed into a private IaaS cloud. This monitoring provides the capabilities needed to be used in an autonomous management system.
