Chapter 2   
           Performance Collection SoftwareAn Overview 

Introduction 

Performance Collection Software consists of four basic programs.  This
chapter discusses how these programs interact, describes the modes in
which Performance Collection Software functions, and provides information
about softkeys and native language support (special features of the
UTILITY and EXTRACT programs).

The basic programs are

   *   SCOPE (or SCOPEXL, depending on your system),

   *   SCOPE2 (or SCOPEXL2),

   *   UTILITY, and

   *   EXTRACT.

Performance Collection Software Schematic 

The following schematic diagram shows the relationship between the
different components of the Performance Collection Software system.  The
components comprising the host programs are shaded.

Current HP LaserRX/MPE Users 

Significant changes were made to enhance the Performance Collection
Software product since the version-A releases (versions A.nn.nn) of HP
LaserRX/MPE. These changes include the following:

   *   New log file formats.

   *   A command-driven user interface for UTILITY and EXTRACT.

   *   The ability to log disc-space metrics.

   *   New THRESHOLD directives.

   *   Increased and enhanced functionality for UTILITY and EXTRACT.

   *   New log files in the SCOPE.SYS group.

For details on Performance Collection Software enhancements, see chapter
8.


CAUTION  The command-driven user interface and the new log file formats
         require that you alter your UTILITY and EXTRACT batch jobs, and
         that you convert existing log files to the new format.  For
         these reasons, we strongly recommend that you review the
         information on the UTILITY and EXTRACT programs before you try
         to use the new versions.

         The operation of SCOPE(XL) has not changed.  The batch job that
         runs the data collector should not require any changes.
