Delivered Assignments of the Collection/Reorganization Schemata

Definition

By assigning MTE classes to a collection and reorganization schema, you collect this MTE class in the Central Performance History (CPH). You can make these assignments yourself (see Assigning Performance Values to Collection and Reorganization Schemata), however you can also use the assignments delivered by SAP.

The standard assignment contains a selection of MTE classes for the following topics:

· Utilization of the CPU and scope of operating system paging (see Operating System Monitor)
· Performance of the dialog system (see Dialog Overview Monitor)
· Availability of systems, logon groups, and application servers (see Availability and Performance Overview Monitor)

Use

The delivered assignments only trigger the collection of the associated MTE classes in the CPH after you have activated the Central Performance History.

Structure

By default, the following MTE classes are assigned to one or both of the following delivered collection and reorganization schemata:

· SAP_HOUR_COLLECTION_WITH_AGGR_TO_DAY

MTE Class	Description
R3DialogResponseTime	Average response time of the dialog service that includes the entire processing time of a dialog step, the time for the network transfer and the processing time at the frontend are not taken into consideration
R3DialogFrontEndNetTime	The time used in the network during the first data transfer from the frontend to the application server and during the last data transfer from the application server to the frontend.
R3DialogDefLoadTime	Average response time of a standard transaction that simulates the normal workload of a transaction by accessing data on the database and executing a range of ABAP function modules
R3UsersLoggedIn	Average number of users currently logged on
Availability_SysPercent	Average availability of a system
Availability_GroupPercent	Average availability of a logon group
Availability_InstPercent	Average availability of an application server

· SAP_QTR_COLLECTION_WITH_AGGR_TO_DAY

MTE Class	Description
CPU_Utilization	Average usage of the CPU in a host system; the value shows how intensively the CPU is used and how much processing capacity is still available
5minLoadAverage	Average number of processes in a host system that are ready for execution but must wait to be processed by the CPU
Page_In	Average number of page-ins per second; a page-in occurs if a process must access a data page that is not available in the main memory. Before the process can be continued, the operating system must retrieve the page from the paging file
Page_Out	Average number of page-outs per second (page-out occurs if a page is stored out of the main memory to make room for the pages required by other processes)
