NAME¶
sa1 - Collect and store binary data in the system activity daily data file.SYNOPSIS¶
/usr/lib/sysstat/sa1 [ --boot | 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 command collects and stores binary data in the /var/log/sysstat/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 no arguments are given to sa1 then a single record is written.OPTIONS¶
- --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 restarts from 0.
EXAMPLE¶
To collect data (including those from disks) every 10 minutes, place the following entry in your root crontab file:Debian note¶
The Debian sysstat package has already placed such an entry in your system crontab. Please refer to the /usr/share/doc/sysstat/README.Debian file for details.FILES¶
/var/log/sysstat/saddIndicate the daily data file, where the
dd parameter is a number representing the day of the month.
