NAME
sar, sa1, sa2, sadc - system activity report package
SYNOPSIS
/usr/lib/sa/sadc [t n] [ofile]
/usr/lib/sa/sa1 [t n]
/usr/lib/sa/sa2 [-aAbcdgkmpqruvwy] [-e time] [-f filename]
[-i sec] [-s time]
DESCRIPTION
System activity data can be accessed at the special request of a user
(see sar(1)) and automatically, on a routine basis, as described here.
The operating system contains several counters that are incremented as
various system actions occur. These include counters for CPU utiliza‐
tion, buffer usage, disk and tape I/O activity, TTY device activity,
switching and system-call activity, file-access, queue activity, inter-
process communications, and paging. For more general system statistics,
use sstore(1), iostat(8), sar(1), or vmstat(8).
sadc and two shell procedures, sa1 and sa2, are used to sample, save,
and process this data.
sadc, the data collector, samples system data n times, with an interval
of t seconds between samples, and writes in binary format to ofile or
to standard output. The sampling interval t should be greater than 5
seconds; otherwise, the activity of sadc itself may affect the sample.
If t and n are omitted, a special record is written. This facility can
be used at system boot time, when booting to a multi-user state, to
mark the time at which the counters restart from zero. For example,
when accounting is enabled, the svc:/system/sar:default service writes
the restart mark to the daily data file using the command entry:
su sys -c "/usr/lib/sa/sadc /var/adm/sa/sa`date +%d`"
The shell script sa1, a variant of sadc, is used to collect and store
data in the binary file /var/adm/sa/sadd, where dd is the current day.
The arguments t and n cause records to be written n times at an inter‐
val of t seconds, or once if omitted. The following entries in
/var/spool/cron/crontabs/sys will produce records every 20 minutes dur‐
ing working hours and hourly otherwise:
0 * * * 0-6 /usr/lib/sa/sa1
20,40 8−17 * * 1−5 /usr/lib/sa/sa1
See crontab(1) for details.
The shell script sa2, a variant of sar, writes a daily report in the
file /var/adm/sa/sardd. See the OPTIONS section in sar(1) for an expla‐
nation of the various options. The following entry in
/var/spool/cron/crontabs/sys will report important activities hourly
during the working day:
5 18 * * 1−5 /usr/lib/sa/sa2 -s 8:00 -e 18:01 -i 1200 -A

NOTES
The sar service is managed by the service management facility, smf(7),
under the service identifier:
svc:/system/sar
Administrative actions on this service, such as enabling, disabling, or
requesting restart, can be performed using svcadm(8). The service's
status can be queried using the svcs(1) command.
Starting in the Oracle Solaris 11.4 release, the StatsStore is provided
to record a wider array of statistics than sar and to view them in more
ways, including the System Web Interface. See the Using Oracle Solaris
11.4 StatsStore and System Web Interface book for more information.
