Background documentation Monitoring the ABAP Performance Locate the document in its SAP Library structure

You can use the ABAP Key Performance Indicators monitor to obtain the most important values about the performance of the instances of your ABAP system or monitored ABAP systems and to identify possible causes for performance problems. You can see areas that you particularly need to monitor in your daily administration at a glance in the subtrees of this monitor.

Execution

Check the ABAP Key Performance Indicators monitor for alerts. To open the monitor, proceed as described in Tasks. Depending on the affected nodes, you can react to the alert as follows:

Affected MTE

Description

Dialog Service

This subtree contains the most important performance values of the ABAP dialog service. The Structure linkWorkload Monitor (transaction ST03) is set as the analysis method.

   <SysID>\<instance>
        FrontendResponseTime
        ResponseTime
        UsersLoggedIn

These nodes (dialog response time, front end dialog response time, and the number of users logged on) summarize the current situation of the dialog service.

For possible procedures if alerts occur, see:

·        Structure linkDialog Overview Monitor

·        Structure linkDialog per Application Server Monitor

Operating System

This subtree contains the most important performance values at operating system level, which are collected by the operating system collector SAPOSCOL. The Structure linkOperating System Monitor (transaction OS06) is set as the analysis method.

    <SysID>\<instance>\...
        CPU_Utilization
        Page_In
        Page_Out

These nodes (CPU utilization and paging rates) summarize the current utilization of the operating system resources.

For possible procedures if alerts occur, see Structure linkOperating System Monitor.

Memory management

This subtree contains the most important performance values of the SAP memory management system. The Structure linkTune Summary (transaction ST02) is set as the analysis method.

    <SysID>\<Instance>
        R3RollUsed
        EsAct
        HeapAct
        Swap

These nodes show the following values:

·        Structure linkSAP Roll Area

·        Structure linkSAP Extended Memory

·        Structure linkPrivate Memory

·        Page outs due to full buffers per minute (see Structure linkSwap Space Requirement)

If alerts occur in this area frequently, you should reconfigure the memory management (see Structure linkPlatform-Specific Description of Memory Management).
