As the increasing use of the cloud computing, virtualization technology have been combined and applied a variety ofrequirements. Cloud computing has the advantage that the support computing resource by a flexible and scalable to users as theywant and it utilized in a variety of distributed computing. To do this, it is especially important to ensure the stability of the cloudcomputing. In this paper, we analyzed a variety of component measurement using open-source tools for ensuring the performanceof the system on the education system to build cloud testbed environment. And we extract the performance that may affect thevirtualization environment from processor, memory, cache, network, etc on each of the host machine(Host Machine) and a virtualmachine (Virtual Machine). Using this result, we can clearly grasp the state of the system and also it is possible to quicklydiagnose the problem. Furthermore, the cloud computing can be guaranteed the SLA(Service Level Agreement).
