Hi:

I'd use 'glance'. Of course, you have to purchase a license if you don't have it [aside from a 30-day free trail version from the Application CDROMs].

Regards!

Re: Total, Used and Free memory in HPUX

There are many possible solutions, Glance without a doubt being the best. Also available are vmstat, swapinfo, sar, even ps. The problem with all these freely available tools, other than Glance, that is, is that they all have their own unique way to look at memory and therefore give different answers. That is why Glance is so clearly superior and no system should be without it.

Senthil,
Following will display the top 10 process which is using high CPU/MEmory.

UNIX95= ps -ef -o pid,ppid,pcpu,args | sort -nbk 3 | tail -10

No. that will show only processes with high CPU, it will not show the memory usage of processes at all... if you wanted to look at (virtual) memory usage of a process (in kilobytes) you might do:

UNIX95= ps -eo pid,ppid,vsz,args | sort -nbk 3 | tail -10

Hi Sharma Sanjeev,

The script posted by you is showing total, used and free memory for phusical and swap.


Now i want to view the top 3 memory (physical) utilizing process.

Re: Total, Used and Free memory in HPUX

Take Duncan's command and use sz instead of vsz (Physical instead of Virtual).

UNIX95= ps -eo pid,ppid,sz,args|sort -nbk 3 |tail -10

Re: Total, Used and Free memory in HPUX

Hi Don,

is "sz" showing the size of physical memory in KB or MB?

Actually i want to view in percentage format.

Example:

pcpu - will display the percentage of cpu usage.

like that i want to view the memory in percentage for each process. (like "pmem" in linux)
