Using SAS System Options to Track Resources

You can specify one or more of the SAS system options STIMER, MEMRPT, FULLSTIMER, and STATS to track and report on resource use. The availability, usage, and functionality of these options vary by operating environment, as described below:
Option
z/OS
UNIX and Windows
STIMER
Specifies that the CPU time is to be tracked throughout the SAS session.
Can be set at invocation only.
Is the default setting.
Specifies that CPU time and real-time statistics are to be tracked and written to the SAS log throughout the SAS session.
Can be set either at invocation or by using an OPTIONS statement.
Is the default setting.
MEMRPT
Specifies that memory usage statistics are to be tracked throughout the SAS session.
Can be set either at invocation or by using an OPTIONS statement.
Is the default setting.
Not available as a separate option; this functionality is part of the FULLSTIMER option.
FULLSTIMER
Specifies that all available resource usage statistics are to be tracked and written to the SAS log throughout the SAS session.
Can be set either at invocation or by using an OPTIONS statement.
In the z/OS operating environment, FULLSTIMER is an alias for the FULLSTATS option.
This option is ignored unless STIMER or MEMRPT is in effect.
Specifies that all available resource usage statistics are to be tracked and written to the SAS log throughout the SAS session.
Can be set either at invocation or by using an OPTIONS statement.
In Windows operating environments, some statistics are not calculated accurately unless FULLSTIMER is specified at invocation.
STATS
Tells SAS to write statistics that are tracked by any combination of the preceding options to the SAS log.
Can be set either at invocation or by using an OPTIONS statement.
Is the default setting.
Not available as a separate option.
SAS system options are initialized with default settings when SAS is invoked. However, the default settings for some SAS system options vary both by operating environment and by site. For details, see the SAS documentation for your operating environment.
You can turn off any of these system options by using the options below:
  • NOSTIMER
  • NOMEMRPT
  • NOFULLSTIMER
  • NOSTATS
Note: In the z/OS operating environment, NOFULLSTIMER is an alias for the NOFULLSTATS option.
Note: Guidelines for interpreting the statistics that are generated by the FULLSTIMER SAS system option are also available at support.sas.com.
Note: You can also use SAS Application Response Measurement (ARM) macros to monitor the performance of your applications. ARM macros are not covered in this course. To learn more about ARM macros, see the SAS documentation and detailed information about ARM macros at support.sas.com.
