ARM Performance Macros

Example: ARM Performance Macros

The following example code writes output to the SAS log. The application name is Perf_App. There are two transactions, Perf_Tran_1 and Perf_Tran_2. The performance macros are highlighted within the code.

%log4sas();
%log4sas_logger(Perf.ARM, 'level=info'); 
options armagent=log4sas; 
%let _armexec=1; 
%perfinit(appname="Perf_App");

%perfstrt(txnname="Perf_Tran_1");
  data x;
  do i=1 to 10000;
  x=i; y=0-i;
  output;
  end; 
run;

  proc sort  data=x threads; by y;  
run;
%perfstop;

%perfstrt(txnname="Perf_Tran_2");
  data x;
  do i=1 to 10000;
  x=i; y=0-i;
  output;
  end; 
run;
  proc sort  data=x threads; by y;  
run;
%perfstop;

%perfend;
run;

The following is the SAS log output for the example code. Note the performance macros that were highlighted in the example code.
