Check through Glance,

# glance

then press m for memory usage to check

Or Use below command,

UNIX95= ps -ef -o vsz,pid,user,pcpu,args"|sort -rn -k1

The "memory" line in the output of swapinfo is NOT physical memory, rather it is pseudoswap which is calculated to be 75% the size of RAM.

Provide the top output.

Download kmeminfo and run. this will show you the memory utilization.

This utility is not supplied by default with the OS. It is a single binary file. You can put it anywhere you like after you acquire it.

What is HP-UX OS version?

You can download kmeminfo and use it.
There is one more script attached that I found on the Forum. You can check with this also.

Output like:

# memdetail
