HP SPT/XL User's Manual: Analysis Software

Logfile Summary Information 

This screen shows the top 10 intrinsics (based on processing time) that
HP SPT/XL found when it monitored your program.  It shows the percentage
of time spent in both the system code and your application code.  It also
displays the total processing time.  You can use this total time to
verify that optimization worked.

To further analyze the time spent in system code, use the Transaction
Intrinsic Profile screen.  To further analyze the time spent in
application code, use the Code File Sample screens.

Processing time spent in system code includes all time in the intrinsics
intercepted by HP SPT/XL during collection.

Processing time spent in application code includes all time spent in
execution of program file code, user executable library (XL), code and in
any intrinsics not intercepted by HP SPT/XL.

Since access to mapped files using pointers bypasses the MPE File System
Intrinsics, this time is accumulated in application code.

Access this screen by selecting  Analyze on the Main Menu and enter a
logfile name.  You will only see this screen if you have not yet
restructured the logfile for transactions.  Or you can select  Redefine 
Trans to display this screen.

Screen Definitions 

% of Total Processing     Percentage of program's total processing time
Time                      in application and system code.

Application code          Application program procedures.

System code               System intrinsics.

Total processing time     Time HP SPT/XL monitored the program, minus
                          time spent in waiting for terminal input.

Intrinsic name            Top 10 intrinsics in the program.

Calls                     Times this intrinsic was called.

Time (sec)                Processing time spent in this intrinsic minus
                          time spent waiting for terminal input.

% of Total Processing     Percentage of total processing time spent in
Time                      this intrinsic.

Histogram                 Graphic representation of the percentage of
                          total processing time spent in this intrinsic.

                          It is understood as follows:

                            C to C = CPU time.

                            * to * = Wait time.

                            C to * = Total processing time.
