The Operating System Layer
Besides the SystemDetails test, DiskActivity test, DiskSpace test, Uptime test, and MemoryDetails test that have been already discussed, the Operating System layer of an Oracle server can be optionally enabled to execute the following tests. These tests are disabled by default. To enable a test, open the agents – tests configuration page using the Agents -> Tests -> Configure menu sequence, select Oracle Database from the Select a component type list, go to the disabled tests section, click on the check box preceding this test, and finally, click on the Update button.
