SA1(8) Linux User's Manual SA1(8)
sa1 - Collect and store binary data in the system activity daily data
file.
/usr/local/lib64/sa/sa1 [ --boot | interval count ]
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
command collects and stores binary data in the current standard
system activity daily data file.
The standard system activity daily data file is named saDD unless
sadc's option -D is used, in which case its name is saYYYYMMDD, where
YYYY stands for the current year, MM for the current month and DD for
the current day. By default it is located in the /var/log/sa
directory.
The interval and count parameters specify that the record should be
written count times at interval seconds. If no arguments are given to
sa1 then a single record is written.
The sa1 command is designed to be started automatically by the cron
command.
--boot This option tells sa1 that the sadc command should be called
without specifying the interval and count parameters in order
to insert a dummy record, marking the time when the counters
restart from 0.
To collect data (including those from disks) every 10 minutes, place
the following entry in your root crontab file:
0,10,20,30,40,50 * * * * /usr/local/lib64/sa/sa1 1 1 -S DISK
/var/log/sa/saDD
/var/log/sa/saYYYYMMDD
The standard system activity daily data files and their
default location. YYYY stands for the current year, MM for
the current month and DD for the current day.
