How does PrEstoCloud support cloud-based monitoring at infrastructure-level?

A set of infrastructure-level metrics (e.g. CPU, memory, disk, etc.) related to cloud-based servers should be measured continuously whether by the infrastructure provider’s monitoring probes or by the PrEstoCloud monitoring probes. Monitoring probes periodically send the monitoring data to the “Message Broker” component from which it can be distributed to any other PrEstoCloud component such as the “Autonomic Resource Manager”. It should be noted that the monitoring data are mainly exploited by the “Situation Detection Mechanism (SDM)” and the “Workload Predictor”.
