The Operating System Layer

One of the key functions of this layer is to monitor the CPU/memory/disk resources utilized by the Windows host, and report whenever there is excessive resource usage at the host. Figure 1 depicts the tests associated with this layer.

Since most of the tests listed in Figure 1 have already been dealt with in Chapter 1, this section deals with the SystemDetails test (as the test parameters applicable are slightly different for Windows systems), the DiskActivity test (as it reports a different set of metrics for a Windows server), the MemoryDetails test (as it reports additional measures for Windows sytems), the WindowsSystem test and the PageFiles test only.
