I am running Solaris 10 in a sparc environment.
I have the sys crontab setup to use sar to gather data and report it.
My sys crontab entry looks like this:
0,5,10,15,20,25,30,35,40,45,50,55 * * * 0-6 /usr/lib/sa/sa1
20,40 8-17 * * 1-5 /usr/lib/sa/sa1
5 18 * * 1-5 /usr/lib/sa/sa2 -s 8:00 -e 18:01 -i 1200 -A
I can manually run the sar command and it will report sar data to the screen: i.e. if I run sar 1 10 it will report, to the screen, 10 instances every one second
However, whenever I depend on the cron job to run sar and report back the statistics in the /var/adm/saXX files, it will not report.
If I run the sar command by itself, I get the message:
sar: can't open /var/adm/sa/sa19
My question is this, why is the cron job not saving the data in the
/var/adm/saXX file?
On a server in which sar is reporting correctly, I can run the sar command (no arguments or switches) by itself and it will correctly report as follows:
SunOS cl1eriaps04 5.10 Generic_125100-08 sun4v 10/15/2007
