The Operating System Layer
Using the tests mapped to this layer, administrators can determine the percentage of physical CPU/disk/memory resources that are used by a QVD Server Node, and thus understand whether/not the node is right-sized. In addition, the tests associated with this layer also monitor the current state of and the load on the target Server Node, and in the process, alert administrators to the abnormal state of the node or a potential overload condition.
Most of the tests of this layer have been dealt with in the Unix and Generic Servers
