SA1(8) Linux User's Manual SA1(8)NAME
sa1 - Collect and store binary data in the system activity daily data file.
SYNOPSIS
/usr/lib/sa/sa1 [ interval count ]
DESCRIPTION
The sa1 command is a shell procedure variant of the sadc command and handles all of the flags and parameters of that command. The sa1 com-
mand collects and store binary data in the /var/log/sa/sadd file, where the dd parameter indicates the current day. The interval and count
parameters specify that the record should be written count times at interval seconds. If you do not specify these parameters, a single
record is written.
The sa1 command is designed to be started automatically by the cron command.
EXAMPLES
To create a daily record of sar activities, place the following entry in your root or adm crontab file:
0 8-18 * * 1-5 /usr/lib/sa/sa1 1200 3 &
FILES
/var/log/sa/sadd
Indicate the daily data file, where the dd parameter is a number representing the day of the month.

sa1 -- Generate a system activity daily data file.
SYNOPSIS
/usr/lib/sa/sa1 [t n]
DESCRIPTION
The sa1 command is a shell script used to invoke the system activity data collector, sadc. The binary sample data is collected at intervals
t seconds apart, in a loop n times. The binary sample data is written to the standard daily data file, /var/log/sa/sadd where the dd repre-
sents the current day of the month.
sa1 is intended to be started by cron.
EXAMPLE CRON ENTRY
# Starting at 8am collect system activity records
# every 20 minutes for 12 hours
# 20 minutes = 1200 seconds
# 12 hours with 3 samples each hour = 36 loops
0 8 * * 1-5 /usr/lib/sa/sa1 1200 36
# After the 12 hour period,
# collect a system activity report
30 20 * * 1-5 /usr/lib/sa/sa2 -A
FILES
/var/log/sa/sadd Default daily activity file that holds the binary sampling data. dd are digits that represent the day of the month.
