Code File Sample Profile 

One way HP SPT/XL monitors an application is by frequently sampling the
instruction address where the application is executing.  The screen in
Figure 5-1 lists these samples by procedure name for the specified
program or library file.  See "Collecting Data" in chapter 1 for more
information.

You would typically use this screen when you are analyzing an
application's time spent in user code or application code.

Access this screen by selecting  Sample Profile to display the Code File
Sample Summary screen, then select  FileSmpl Profile.

Screen Definitions 

Procedure Name            Procedures sampled during this transaction from
                          the selected code file.

Sampling...               Reminder that the SYSPROCNAMES option was
                          disabled during data collection.

Sample Count              Number of times a procedure was sampled.

% of Samples              Percentage of samples taken from this
                          procedure.

% of Transaction Process  Percentage of overall transaction processing
Time                      time spent in this procedure.

Histogram                 Graphic representation of percentage of overall
                          transaction processing time spent in this
                          procedure.

 Prc Smpl Profile         Prompts for procedure name, then displays the
                          Detailed Procedure Sample Profile screen.


NOTE  A procedure name preceded by a question mark (?)  signifies that
      the code is associated with a procedure call export stub, which is
      the entry location used by callers from external modules.  Refer to
      the Procedure Calling Convention Reference Manual (09740-90015) for
      a more detailed discussion of export stubs and native-mode
      procedure organization.


It is possible to have more than one procedure with the same name in the
same executable library file.  For example, if an executable library has
two object modules, both can have local procedures of the same name.  To
identify these procedures uniquely, HP SPT/XL puts the starting address
of the procedure in parentheses in front of the procedure's name--for
example, (3A5)PROC1 and (304B)PROC1.

If you select  Prc Smpl Profile, you will be prompted for the procedure
name.  The entire name, including the address, should be entered.  The
names are case sensitive.
