SMF statistics are generated by IBM's System Management
Facility. If your system is configured to enter the SMF exit, and
if the SAS system options SMF and SMFEXIT= are in effect, up to 20
SMF statistics can be written to the SAS log for each task.
SMF statistics are written
to the SAS log only when the STATS system option is in effect.
For further information
about SMF statistics, see the configuration instructions for SAS in
the
z/OS environment.
