sar: Can't open /var/adm/sa/sa22

[K.Vijayaragavan.]

Hi,

1)When i do "sar" i get this error message stating "sar: Can't open /var/adm/sa/sa22".

2)Created this file manually and when i do "sar" once again it does nothing.

3)Issued the command (seen from man page)," /usr/lbin/sa/sadc /var/adm/sa/sa`date +%d` " to create sa## as described.

After this if i do sar,

It gives message stating -->
HP-UX wks1 B.11.00 A 9000/785 03/22/02

"Memory fault(Core dump)"
<---

How do i get it resolved?

Note:
->55% of /var is only used.
->It is on HPUX 11.00 B2000 Wks

Hi,

if you launch sar without timing specifications it will get its data from an history file, which is created by a cronjob.

To see current statistics use for example:
sar -d 5 5
(display disk statistics 5 times with 5 seconds interval)

good luck,
Thierry.

Hi

to inetractively run sar try these commands

sar 1 5

sar -o temp 60 10

sar -d -f temp

sar -u -M -f temp

checkout man pages

cheers
John.

Hi

Cron this to start each day, I use 05:00 Hrs
And it will create and run sar throughout the day - each and every day.


00 05 * * * /sysadmin/sardump

----------------Cut here------------------

#!/bin/sh

# 1 minute
period=${1:-"60"}


iterations=${2:-"`expr 86400 / $period`"}


echo "sar: $iterations iterations at $period second intervals"
/usr/sbin/sar -A \
-o /var/adm/sa/sa`date +%d` \
$period \
$iterations > /dev/null
------------------ Cut Here-----------


Change the -A switch to suit.

There should be a sa1 script in your /usr/lbin/sa dir. You can put it in your crontab file to create a daily sar output file like:
0 * * * * /usr/lbin/sa/sa1 1200 3
This script creates an entry every 20 minutes in the output file sa.
See man sa1 for more details.
And remember to create the /var/adm/sa dir if it doesn't already exist.

Hi,

Accounting is already turned on.

checked "/etc/rc.config.d/acct" for the entry "START_ACCT=1" and
rebooted the workstation

Still "sar , sar -d" gives memory fault(core dump message) .

rest all like,
1)
"sar 1 5 and
sar -o temp 60 10"
works fine.

2)
"sar -d -f temp" - returns to #prompt.

3)
"sar -u -M -f temp " - just returns to #prompt.

Hi Ruediger,

Tried as you mentioned.
But still "sar" and "sar -d " ,displays "Memory fault(Core dump)"

Do you need a sar patch?

On my 11.0 box i have installed the patch bundle from March 2001 but no further single patches for sar.

Hi

2)
"sar -d -f temp" - returns to #prompt.

3)
"sar -u -M -f temp " - just returns to #prompt.

Hi John,

Yes! it creates the temp file.

But the commands "sar & sar -d " alone wont work and gives "memory fault (core dumped) error."

Hi Vijay,

Perhaps your sa## file is corrupted. I'd delete it (rm /var/adm/sa/sa##) and recreate it with:
/usr/lbin/sa/sa1

Then running sar (without specifying the interval and number of repetitions) should automatically select the sa## file for the current date.

man sa1 for more info, especially for running it via cron.

By the way, you don't have to turn on accounting for sar.

Hi

You have to specify sar with some argument like sar 2 2 or sar -d 2 2 to make it work

Hi ruediger,

can you mention the PATCH id of the sar patch you were mentioning?

-Vijay

[Ruediger Noack]

Sorry, I have *NOT* installed an additional sar patch, only the complete patch bundle March 2001 on my box and sar runs fine.
May be there are some filesets / patches on your box not configured?
Check with:
swlist -l fileset -a state
