6.1.1.1 NPM Network Collector Function

The NPM Network Collector Function records volume,
performance, and reliability data, as collected in the
Network Control Program (NCP), which is the communication
controller's operating system.

NPM communicates with the Network Performance Analysis
Logical Unit (NPALU) in the NCP to retrieve data and record
it in one of three places:

o  A review file, which CA MICS does not process
o  The network log
o  SMF records

In z/OS, the data recorded by the NCP is transmitted to the
host processor and is written by an NPM host-based routine
into the SMF data set.

In VM, the SMF equivalent type 28 records are written to the
CMS files named on the FNMLOG2 FILEDEF statements in the NPM
startup EXEC.  It is your responsibility to transport the VM
NPM log files to your CA MICS z/OS host.

The NPM Network Collector Function builds a review file and
the NPM Network Log.  The Network Log can be written to a
sequential log file or the SMF data set.  For VM NPM, the
Network Log can be written to an SMF-equivalent CMS file.

The CA MICS Network Analyzer Option requires that the data be
in SMF or SMF-equivalent form (SMF type 28 for NPM).  It is
your responsibility to archive SMF data on a regular basis
for input to CA MICS DAILY update process. If you are running
VM NPM, it is also your responsibility to transport the data
to your CA MICS z/OS host.
