The monitoring mechanisms of open-source IaaS software OpenNebula and monitoring system Ganglia were analyzed. Reduce overload of retrieving resource usage information by deploying the Ganglia monitoring agent. And for improving the robustness of monitoring subsystem, the authors take measures on the privileged domain of virtualization nodes to hide the agent to prevent regular or malicious users checking, modifying, unloading or killing it intentionally or unintentionally. The mechanism is very helpful to enhance the effectiveness, reliability and sturdiness of the monitoring system of IaaS platforms.
