Sar reporting incorrect date and average

dev44 — Mon, 15 Feb 2010 14:58:04 GMT

System: Proliant DL585
OS: RHEL 5.3 64 bit

When I type "sar", I get the following:

Linux 2.6.18-128.el5 (server) 01/13/2010 <- WRONG DATE

Average: all 38.93 0.01 15.10 10.63 0.00 3407.78

So the date and average are way off.

However, if I do a sar 5 5 it works fine.
Any ideas?

Here is what I have in my sysstat:
# run system activity accounting tool every 10 minutes
*/10 * * * * root /usr/lib64/sa/sa1 1 1
# generate a daily summary of process accounting at 23:53
53 23 * * * root /usr/lib64/sa/sa2 -A

Shalom,

Check the date command, your system date may be off.

You should consider using the date command to update it (as root) and then ntp to keep it synced up.

chkconfig --list ntpd

chkconfig ntpd on

What is the date stamp on /var/log/sa/sa(DAY) <
If it is not today then your sa1 script is not working.

The date is fine...we are using ntp. As I said in my first post...if I do a "sar 5 5" the date and averages are fine.
The problem is when I type

#sar

or

#sar -f sa15
