problem with sar command

UNIX Solaris
1

hi all:-
when i try to use sar command i get this error how can i fix it

bash-3.00# sar -A
sar: can't open /var/adm/sa/sa16
No such file or directory

In order to report on historical data, that historical data must exist.
See "man sadc" for example crontab entries.

Alternatively, if you look for current values, you can provide a sampling interval and count.
eg:

sar -A 5 12

For historical data

  1. Uncomment the lines in /etc/init.d/perf file to enable system activity data gathering.
  2. /etc/init.d/perf start
  3. You will also need to uncomment the sa entries in the system crontab /var/spool/cron/crontabs/sys

Indeed. On Solaris 10 and newer, the command would be:

svcadm enable svc:/system/sar

Then uncomment the last three lines in the sys crontab and modify them if you need to:

EDITOR=vi crontab -l sys
...
0 * * * 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
