determine free memory

[Amresh Prasad]

Hi all,
I'm trying to find out how to obtain memory usage information (used/free vs total physical memory) on an HPUX 11 box. Is there a utility/command that gets this information easily?
Also, when one uses 'swapinfo' to get the swap space information, does the amount listed under memory include regular memory usage or is it just memory swap space?

Hi Amresh,

You can use "top" to see (among many other things) your memory usage. Top is included with the OS. If you purchased GlancePlus, you can use the memory report (m) in it to observe your data, also.

The "memory" item in a swapinfo output is pseudoswap usage. Pseudoswap is imaginary swap (the OS lying to itself, if you will). It consumes no physical RAM and no disk space.

All The Best,
Jim

Hi,
You can use vmstat check man pages for vmstat will give you the details. The memory listed with swapinfo is the system memory avail for paging if I understand correctly.
Also you can use Glance which is more precise.

Goodluck.
