6.1.4.2 CA NetSpy NCP Interface

The CA NetSpy NCP Interface records volume, performance, and
reliability data that is collected by a function in the
Network Control Program (NCP) called the NPA Logical Unit
(NPALU).  The NPALU collects data and reports it to the CA
NetSpy NCP Interface in the same way it performs this
function for Tivoli NPM.  CA NetSpy then records this data in
subtype N of its SMF record (or the VM equivalent).

Information may be collected for one or more NCPs, lines,
physical units (PUs), or logical units (LUs).  Start
parameters within CA NetSpy permit the installation to
control the data collected from various NCPs.

Because data from the CA NetSpy NCP Interface is so similar
to that provided by Tivoli NPM Network Subsystem, the CA MICS
Network Analyzer writes this data directly into four SNA
Network files shared with NPM Network data:

o  NCP Link File (SNTNCL)
o  NCP Activity File (SNTNAF)
o  Network Components Activity File (SNTCAF)
o  Network Incident File (SNTNIN)

Information supplied by the CA NetSpy NCP Interface includes
the following data types:

o  NCP Data
   --------
   NCP information includes the CCU cycle speed, used cycle
   time, buffer and channel queue statistics, and the amount
   of time in slowdown.

o  Line, Controller, and Terminal Data
   -----------------------------------
   Information for lines, controllers, and terminals
   includes message and character traffic counts, outbound
   queue statistics, and poll, error, and retransmission
   counts.
