The Operating System Layer

Since the status of a host depends on its CPU, memory, and disk utilization, the eG Enterprise uses a SystemDetails test that tracks the CPU and memory utilization and DiskActivity and DiskSpace tests that monitor the disk utilization. Figure 1 illustrates the tests that map to the Operating System layer. While the SystemDetails test tracks the overall health of the target host, the DiskActivity and DiskSpace tests report the states of each of the disk partitions of the host individually.
