SAR (SA1) Activity Report

[Charles Legge]

Hello, Even though the man page doesn't specifiy an output option for the SA1 report, can the output be redirected to an alternate mount point other then the default /var/adm/sa?

Thanks in advance, Charles.

The /usr/lbin/sa/sa1 file is a script, which if you really wanted to, you could edit to change the location of the output files.

Hi,
you can also use the -f option with sar command.

/usr/lbin/sa/sa1 is a simple shell script. The variable DFILE specifies the output file name:

DFILE=/var/adm/sa/sa$DATE

You can modify this to put the sa files where you like.

You should update sa2 as well if you plan on using it, as it has /var/adm/sa in several places.

You can also make /var/adm/sa a symlink to another directory, and avoid changing the scripts. This would help if you do and upgrade or patch that replaces sa1 and sa2, since you would lose your changes.

With no sampling interval specified, sar extracts data from a previously recorded file, either the one specified by -f option or, by default, the standard system activity daily data file /var/adm/sa/sadd for the current day dd.

Exapmple, send sar sample to sar.out every 3 sec, 2 times:

# sar -o /tmp/sar.out 3 2
