Solaris

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

00:00:00 %usr %sys %wio %idle
00:05:00 0 0 0 100
00:10:00 0 0 0 100
00:15:01 0 0 0 100
00:20:00 0 0 0 100
00:25:00 0 0 0 100
00:30:00 0 0 0 100
00:35:00 0 0 0 100
00:40:01 0 0 0 100
00:45:00 0 0 0 100

Just FYI...I solved the problem. Seems as though I did not stop/start the cron service daemon after modifying the cron file to enable sar. Running the following command fixed my problem:

svcadm restart svc:/system/cron:default

I have Linux SuSE 10 built recently, when I　ｔｙｐｅ：　
＞　ｓａｒ
Cannot open /var/log/sa/sa17: No such file or directory

（today　ｉｓ　Ｆｅｂ　１７）

Please help what's wrong there, is there package missing or I should use different utility?

Thanks
