/usr/lib/sysstat/sadc system activity data collector binary included in sysstat package.
SADC_OPTIONS="-S XXXXX"in/etc/sysstat/sysstatin Ubuntu- Amazon Linux:
/etc/sysconfig/sysstat
-S DISK -S XDISK -S ALL -S XALL
-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.
