Time at which paging was high??

[Former Member]

Hi,

We had high paging on our production system two days back.

we would like to know the time at which paging was high in a day.

No dumps reported about high paging.

Ours are AIX sytems.

I don't have permission to do "svmon" in OS level

Is there any way of finding the same from OS level.

Regards,

Venkat

In most cases a message is displayed on the console when the system runs out of memory and paging occurs but if you don't have permission to run 'svmon' I doubt you will have permission to view the console log.

Anyway the command would be:

alog -o -f /var/adm/ras/conslog

Hi,

As per your assumption I don't have permission to view the conslog.

I need you help in analyzing this command "sar"

when I did sar -u below is the out put.

sar -u

Can't open /var/adm/sa/sa29

Try running /usr/lib/sa/sa1 <inc> <num>

what is <inc> <num> meant for ????

I am able to go to the path /usr/lib/sa and file sa1 is existing under user "bin"

Venkat.

what is <inc> <num> meant for ????

<inc> is increment ie how many seconds between samples <num> is number of samples

...so eg

sar -u 1 5

...will give you 5 samples with 1 second between each sample.

See 'man sar' or the following [link|http://docs.hp.com/en/B2355-60127/sar.1M.html] for further information.

You should setup sar correctly with a cron and make sure directory /var/adm/sa exists. Otherwise just use the above for current measurement.
