Memory usage

[Aviad Twina]

Hi all,
What is best wat to measure memory usage in hpux 11.00?
Thanks,
Aviad

[Bernhard Mueller]

Aviad,

top
will tell you how much "Free KB" you have.

vmstat 1 1
will list you the free memory pages (4KB)

to monitor for an hour you can use top or run
vmstat 1 3600

To go more into detail, you may consider (buying) Glance, there is 60-day trial version on one of the Application CDs, if you want to take a closer look at it

Regards,
Bernhard

There are a number of tools.
Glance is the most user-friendly, just run it up and type "m".
There is also a number of other tools, best to read the man pages and try them.
vmstat
sar
swapinfo

Or if it's shared memory you're after, use ipcs -ma

Aviad,
Glance is the best tool around here.

you can also use. man ps for more details.
UNIX95= ps -efo pid, vsz, comm

sar is useful as also the top.
HTH,

#UNIX95= ps -e -o ruser,pid,vsz=Kbytes|more

Thank you all.
I'll take a deeper look in each one of your answers and i'll see what's the most suitable for my needs.

Try this one:

/usr/contrib/Q4/bin/kmeminfo

Output looks like:

# /usr/contrib/Q4/bin/kmeminfo
kmeminfo (3.11)
libp4 (5.17): Opening /stand/vmunix /dev/kmem

Loading symbols from /stand/vmunix

Geoff,
Many thanks for your great answer!
Now after you submitted your answer I found the details I wanted to have form the begining.

Geoff,
I need to give non root users the ability to run the kmeminfo.
Do you know if there is a patch/some other sulotion which enables this option?

Sombody posted some cool source code here to get memory detail. The good thing (in your case) is, it doesn't require root privalages. I'm attaching the source, if you need a binary let me know.

HTH.
