6.2.1.3 NPM Network Session Accounting Collection Function

The Tivoli NPM network session accounting function collects
connect time and traffic statistics for terminal sessions.
It collects this information from the NCP NPALU.  NPM Network
session accounting differs from NPM network collection (also
derived from the NPALU) in the following major respects:

   o  Network session accounting identifies sessions partners
      (i.e., PLU and SLU).

   o  Network session traffic statistics are for LU sessions
      and never include line overhead, such as polling and
      retransmissions.

NPM writes network session accounting data to the SMF Type 28
record, subtypes '50'X, '51'X, and '52'X.  CA MICS processes
each of these subtypes.
