      -S { keyword[,...] | ALL | XALL }
             Possible keywords are DISK, INT, IPV6, POWER, SNMP, XDISK, ALL and XALL.
             Specify which optional activities should be collected by sadc.  Some activities are op‐
             tional to prevent data files from growing too large. The DISK  keyword  indicates  that
             sadc  should collect data for block devices. The INT keyword indicates that sadc should
             collect data for system interrupts. The IPV6 keyword  indicates  that  IPv6  statistics
             should be collected by sadc. The POWER keyword indicates that sadc should collect power
             management statistics. The SNMP keyword indicates that SNMP statistics should  be  col‐
             lected  by sadc. The ALL keyword is equivalent to specifying all the keywords above and
             therefore all previous activities are collected.

             The XDISK keyword is an extension to the DISK one and  indicates  that  partitions  and
             filesystems statistics should be collected by sadc in addition to disk statistics. This
             option works only with kernels 2.6.25 and later. The  XALL  keyword  is  equivalent  to
             specifying all the keywords above (including keyword extensions) and therefore all pos‐
             sible activities are collected.

             Important note: The activities (including optional ones) saved in an existing data file
             prevail over those selected with option -S.  As a consequence, appending data to an ex‐
             isting data file will result in option -S being ignored.
