Requirement for ARM Appender

When using ARM, options must be specified in a certain order when setting up the ARM appender. Options can be specified using the SAS command line or OPTIONS statement.

When using the OPTIONS statement, the following order is required:

the ARM appender must be enabled at the INFO diagnostic level before specifying the ARMAGENT= option

the ARMAGENT= option must be specified before the ARMSUBSYS= option

%log4sas();
%log4sas_logger(Perf.ARM, 'level=info'); 
options armagent=log4sas; 
options armsubsys=(arm_proc);

When using the SAS command line, the following order is required:

the ARM appender must be enabled at the INFO diagnostic level before specifying the ARMAGENT= option
the ARMSUBSYS= option must be specified before the ARMAGENT= option
```
"<SAS92_installation_path\sas.exe>"
 -CONFIG "<SAS94_installation_path\nls\en\SASV9.CFG>" 
-armsubsys (arm_proc) -armagent log4sas -logconfigloc logconfig.xml
```
Note: On the command line, the ARMSUBSYS= option is before the ARMAGENT= option. In the OPTIONS statement, the ARMAGENT= option is before the ARMSUBSYS= option.

Note: In SAS 9.4, if you have an ARM appender that is defined in the XML configuration file, you no longer need to set the ARMAGENT=LOG4SAS system option. ARM sets ARMAGENT to LOG4SAS6 internally.
