You need /var/adm/sa directory to store sar data. it's asking for sa17 as 17 is todays date.

It could be a permissions issue on the directory if it is there.

Hello Phani,

Check files under /var/adm/sa.
Above message expects file /var/adm/sa/sa17, which is not present.

For an example , To get the current statistics:
You may run sar 2 2

HP-UX nido B.11.00 U 9000/800 06/17/09

02:41:26 %usr %sys %wio %idle
02:41:28 2 3 5 90
02:41:30 1 3 1 95

Average 2 3 3 92

Check the man page of sar for details:

Cheers!!

Normally if you give ony #sar the result wil be like this only. Always give the interval and count.

you may see the example below

# sar
sar: Can't open /var/adm/sa/sa17
[rx260-15]/
# uname -r
B.11.23
[rx260-15]/
# sar
sar: Can't open /var/adm/sa/sa17
[rx260-15]/
# sar -d 1 1

HP-UX rx260-15 B.11.23 U ia64 06/17/09

03:48:23 device %busy avque r+w/s blks/s avwait avserv
