The Application Processes Layer
For a SAP TREX server instance, this layer is mapped to a Trex Alerts test, which will quickly capture errors/warnings encountered by the SAP TREX server. Apart from this test, this layer is mapped to the Processes test which reports on the status and resource usage of process patterns that have been explicitly configured for monitoring. In addition to these tests, a SAP Process Status test also runs on this layer which is elaborately discussed in the Monitoring the SAP ABAP Instance document. This layer is also mapped to a host of other tests that are discussed already in the Monitoring Unix and Windows Servers document.
