sa1 Command

Purpose

Collects and stores binary data in the /var/adm/sa/sadd file.

Syntax

/usr/lib/sa/sa1 [ Interval Number ]

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 command collects and stores binary data in the /var/adm/sa/sadd file, where dd is the day of the month. The Interval and Number parameters specify that the record should be written Number times at Interval seconds. If you do not specify these parameters, a single record is written. You must have permission to write in the /var/adm/sa directory to use this command.

The sa1 command is designed to be started automatically by the cron command. If the sa1 command is not run daily from the cron command, the sar command displays a message about the nonexistence of the /usr/lib/sa/sa1 data file.
