6.2.4.1 CA NetMaster Network Tracking System (NTS)

CA NetMaster NTS provides services similar to those provided
by Tivoli NetView Session Monitor/NLDM.  NTS data is written
to the CA MICS NLDM files. NTS controls the performance class
(CA NetMaster RTM class) definitions for the Response Time
Monitor (RTM), which is a microcode function provided in the
3174 and 3274 cluster controllers.  NTS is shipped with a
sample user exit to write the RTM data to SMF as the type 39
subtype 3 record.  Additionally, NTS records session
configuration, data traffic, and connect time information in
the SMF type 39 subtypes 4 and 5 record.  This information is
referred to as CA NetMaster accounting data. The CA MICS
Network Analyzer processes these SMF type 39 record subtypes
to add RTM and accounting data to its data base.

The INPUTSMF DD statement specifies the data set name for the
CA NetMaster input data to the NLDM Files. It is your
responsibility to provide an archive file that contains the
SMF type 39 records for daily processing by CA MICS.

RESPONSE TIME MONITOR
---------------------

The RTM function is provided in the 3274 and 3174 cluster
controllers.  This function includes a specific microcode
support level and a hardware timer adapter card that is read
by the microcode.  CA NetMaster RTM data includes average
response time, a count of the responses that occurred within
user-defined response distribution times, and an indicator of
whether installation-defined service objectives were met
during the data recording interval.

Since service objectives may be defined differently for
different network users, NTS permits the installation to
define RTM classes and to associate each response objective
with a specific RTM class.  An RTM class can be anything the
installation defines, from a group of sessions attached to a
particular cluster controller to all TSO sessions.  RTM
classes are established using the CA NetMaster RTM class and
Session class definitions.  NTS RTM classes are equivalent to
NetView performance classes and are referred to as
performance classes elsewhere in CA MICS documentation.

NTS records all RTM data to the SMF type 39 record, but both
NTS and NEWS can initiate collection of the RTM data.  NTS
collects RTM data at session end and in response to NTS
operator commands to view RTM data online.  Only NEWS allows
for collection of RTM data at regular user-defined intervals.


ACCOUNTING AND AVAILABILITY
---------------------------

NTS accounting data consists of statistical data about user
sessions, including connect time, message and data traffic
counts, configuration data, and BIND failure information.

When the NTS accounting function is activated, the SMF type
39 record is written at session start, at session end, and
when a session is rejected due to a BIND failure.

NTS does not automatically synchronize periodic collection of
RTM and accounting data.  Consequently, it may be misleading
to compare RTM and accounting data for a given period.  For
information on how to provide for synchronized collection of
RTM and accounting data at regular intervals, see the
NetMaster Network Error Warning System User Reference,
Planning and Installation documentation.  Also, see Section
6.3.9, Important Usage Notes for the NLL and LSY Files, for a
discussion of this issue and its effect on data in the CA
MICS database.
