6.4.3 Creating Performance Classes for Reporting

Control units (3274s and 3174s) with the Response Time
Monitor feature installed measure end-user response time for
terminal sessions.  This unique feature also allows you to
specify response time objectives as the percentage of all
transactions being less than a predetermined value (in
seconds).  For example, an installation determines that the
terminals attached to control unit XYZ would provide adequate
service if 90% of all transactions have end-user response
times within three seconds.  These objectives are defined to
NetView Session Monitor or CA NetMaster NTS and to the
control unit.  If, during a predefined interval (such as 30
minutes), that objective is not met, the control unit and
NetView or CA NetMaster record the objective as missed.

Response objectives relate to NetView performance classes and
CA NetMaster RTM classes - both of which are referred to here
as performance classes.  A performance class constitutes any
grouping the installation chooses.  For example, all users on
the same link may belong to a performance class; or, all TSO
users may belong to a performance class.  With NetView, the
installation defines the performance class service
objectives, then maps the terminal sessions to the
appropriate performance classes using the NetView MAPSESS
definition statement.  With CA NetMaster, the Session Class
definition provides a similar function to the NetView MAPSESS
definition statement.

The following reports are based on installation-defined
performance class:

  o  Exception Report 12301, Response Objective Missed for
     Performance Class

  o  Tabular Reports

        SNT105, NLDM Service by Performance Class
        SNT115, NLDM Service by Performance Class

  o  Sample Graphic - Application Response by Performance
     Class

  o  MICF Inquiries

        SNTCD1, SNTPD1 - NetView Daily Avg Responses by
           PCLASS
        SNTCD4, SNTPD4 -  NetView Daily % Resp Within Obj by
           PCLS

For more information on how to establish and control NetView
performance classes, refer to the descriptions of the PCLASS
and MAPSESS definition statements in the Tivoli NetView
documentation.  For similar information on CA NetMaster,
refer to the descriptions of RTM classes and Session classes
in the CA NetMaster Network for SNA documentation.
