SNT Throughput Level Analysis

Calculating the Amount of Cross-Domain Traffic
micsrm140
Sometimes the network analyst is faced with the question of which of the network's host processors is the optimum location for a given application. If users in several domains have access to the application, it is advantageous to have the application reside in the domain which generates the greatest load. With a new application, this location is often obvious. But, when an application has been widely used over a long period of time, some analysis may be necessary to determine which domain produces the most transactions.
This analysis can be accomplished fairly easily using the data in the DETAIL timespan cycles of the NLDM Service (SNTNSV) File as follows:
  1. Summarize the data to the PLU, PLDOMAIN and SLDOMAIN
    %INCLUDE INCLLIB(#SNTMACS); MACRO _BY PLU PLDOMAIN SLDOMAIN % MACRO _BREAK SLDOMAIN % PROC SORT DATA=_dSNTX.SNTNSV01 OUT=DOMAINS; BY _BY; RUN; DATA DOMAINS; SET DOMAINS; BY _BY; _NSVSUM RUN;
  2. Report the total response event count (NSVTRESC) by secondary logical unit domain (SLDOMAIN)
    PROC PRINT LABELS DATA=DOMAINS; BY PLU; ID PLUDOMAIN; VAR SLDOMAIN NSVAVTTM NSVPCOBM;
