vmstat analyser and how to check the memory utilisation

Dear HPUX gurus,
would like to seek your advice. Im turning the vmstat capturing. Is there is a tool that can automatically analyse the output for me. If i want to read manually,how to get the memory utilisation? can u help based on the below utilisation as a sample. If let say like below, how do u read the memory utilisation.
kthr memory page disk faults cpu
r b w swap free re mf pi po fr de sr m1 m1 m2 m2 in sy cs us sy id

If I want to know the io from the server, can I use sar or vmstat or I need to turn on the iostat?

Im a newbie.Many many thanks for your advice and reply. Thank you

Re: vmstat analyser and how to check the memory utilisation

The quickest and easiest metric available from vmstat is in the "po" column. As long as that remains 0, you are not paging and your memory is adequate. As the number starts rising above 0, your performance will begin to degrade. Once the number gets above 10, you have a real problem.

Re: vmstat analyser and how to check the memory utilisation

HI

'vmstat' is a Berkeley Unix developed utility and has not be reliable on HP-UX since the migration to ATT Unix at version 10.0. As Pete indicated, 'po', is the only valid metric.

Instead try ps -o and UNIX95.

UNIX95=1 ps -ef -o vsz,ppid,pid,comm

You will many thread here in the forum about others using UNIX95.

You can check more detial memory usage with kmeminfo,
You have to download the tool, dependig on the os version.
