How to determine swap space utilization by process

[S.Rider]

"swapinfo" shows the current overall utilization of swap space. Is there a way to break down swap utilization, to show which processes are the heavy hitters ?

Shalom,

If you set UNIX95=1 there is a whole series of ps commands that can show you utilization of memory by process.

vmstat can give you more information.

glance/gpm a pay for add in from HP lets you drill into a process and see details of use. It is the best tool.

Every process reserves swap at start time in case it needs to be swapped to disk. That is never a problem. What becomes a problem is when a process is actually swapped to disk.

A process being a heavy hitter as far as reserving swap is meaningless. When overall your system starts to page (vmstat) then you have a problem.

You would probably need to use glance. But I would suggest installing more ram. You may have a program or programs that are not necessarily doing much but just have large memory requirements.

There are sophisticated tools, but see if 'top' does it for you. SIZE it virtual, RES is not.

Jay,

Download the attached procsize, ftp to the system,unshar and run with -s and -p options

# procsize -s -p

Hi S.Rider,
There are many ways through which you will get information about memory.Following are some commonly preferred ways:
1]glance --> by using glance command you can check for the memory.
2]swapinfo -->swapinfo prints information about device and file system paging space
By default, swapinfo prints to standard output a two line header as shown here, followed by one line per paging area:
o/p-->
Kb Kb Kb PCT
TYPE AVAIL USED FREE USED


START/ Kb
LIMIT RESERVE PRI NAME

3] top --> display and update information about the top processes on the system

4]ps â -> report process status
