Re: Memory utilisation Isuue

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

Re: Memory utilisation Isuue

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.

Re: Memory utilisation Isuue


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?

Re: Memory utilisation Isuue

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
Memory Stat total used avail %used
