Application Performance Analyzer for z/OS, Version 11.1, User's Guide

Detail line descriptions

Application module

This identifies an application module to which attribution of CPU usage in system routines has been referred. During the measurement, Application Performance Analyzer determined that execution in system modules was initiated by a system request statement (such as a CALL) with an invocation point in the identified application module.

Under Heading This is Displayed
Name Name of application load module in which CPU usage measured in system modules was attributed.
Description Functional description of the load module if one is available. Otherwise, "Application Program" is shown here.
Percent of CPU Time The percentage of attributed system module CPU usage referred back to this application module.

CSECT in application module

These lines appear under the application module detail line. Each one reports an external name (CSECT) within the application module in which invocation points for attributed CPU execution reside.

Under Heading This is Displayed
Name Name of CSECT in which CPU usage measured in system modules was attributed.
Description CSECT in loadmodname appears here.
Percent of CPU Time The percentage of attributed system module CPU usage referred back to this CSECT.

Offset in CSECT

These lines appear under the CSECT detail line. Each one reports a return address offset - the point in the CSECT at which control is returned from the attributed system services CPU usage. This identifies the address of the application statement.

Under Heading This is Displayed
Name The hexadecimal offset of the return point in the CSECT of the system execution invocation request.
Description "Offset in csectname" appears here.
Percent of CPU Time The percentage of CPU time measured in this system routine for the indicated invocation/return address.

Source statement

One or more lines showing the source statement appear at the same level as the Offset in CSECT detail line. This appears only when the source program has been mapped and loaded. For more information, see Source program mapping.

System Module

This line identifies a system module in which CPU usage was measured and attributed to the reported application module.

Under Heading This is Displayed
Name The name of a system module in which CPU usage was measured and referred back to the application module under which this line appears.
Description Functional description of the system module.
Percent of CPU Time The percentage of CPU time measured in this system routine for the invocation/return address under which this line appears.

CSECT in System Module

This line identifies a CSECT within a system module in which CPU usage was measured and attributed to the reported application module.

Under Heading This is Displayed
Name The name of the CSECT in which CPU usage was measured and referred back to the application module under which this line appears.
Description Functional description of the CSECT.
Percent of CPU TIme The percentage of CPU time measured in this system CSECT for the invocation/return address under which this line appears.

Unresolved address

This line identifies an unresolved address in which CPU usage was measured and attributed to the reported application module.

Under Heading This is Displayed
Name An unresolved address range in which CPU usage was measured and referred back to the application module under which this line appears.
Description "Unresolved Address"
Percent of CPU Time The percentage of CPU time measured in this address range.
