Hi Reuven

There is hp tool called kmeminfo with which you can view the split memory utilization of each process.

I'm attaching a script which calculates top processes using memory.

syntax: mem.sh <# of processes>

Hi reuven,

You can always use common unix tools like top,sar,iostat and vmstat. But if you want to use the HP proprietary tools, you can go ahead using glance or gpm. However, if you are using HPUX 11iv3 and the foundation operating environment, you might not be able to run glance. The best way to learn how to use the command glance is by using the man page and things that were done by sar are very readily done by glance as well.

Hi:

These unix tools: top,sar,iostat and vmstat, will perform differently depending upon the O/S. However, using the 'ps' command with the -o argument to monitor 'vsz' and 'rsz' seems to be very reliable on solaris, hp-ux, and linux. The only difference between the two is 'vsz' is in kb and 'rsz' is in blocks, so there may be so more accuracy with blocks. Just learn the conversion.

Here is the basic command:

ps -e -o vsz,pid,ppid,comm | sort -rn | more

For HP-UX its:

UNIX95=1 ps -ef -o vsz,pid,ppid,comm | sort -rn | more

Note that the 'UNIX95' temporarily references the X open or XPG4 ps command format which allows you to use the -o options from Berkely UNIX. (* HP-UX defaults to the System 5 / ATT format *)
