How to get physical memory usage.

[jeevarajkn]

Dear Gurus

Is swapinfo will give physical usage or I want to go for TOP command as Glance is not installed in my server.

Hi

Please check the ipcs .
Using this command you can find the shared memory usage

Use

dmesg | grep physical
top
glance
swapinfo -tam

Thanks

Hi,

The total memory can be seen with:
- glance, memory (m) report
- top
- dmesg
- also logged to the file, /var/adm/syslog/syslog.log
The free memory on the system can be seen with:
- glance, memory (m) report
- vmstat

The swap space being used can be seen with:
- glance, swap space (w) report
- swapinfo

If you want to find which processes are using what memory

Then to find the actual size (sz) and Virtual size (vsz) use the below command

#UNIX95=1
# ps -efo vsz,sz,pid,args |grep -v grep | sort -rnk 1 | more

You don't have an entry for "memory". You need to enable the kernel parm swapmem_on.

>Sagar: #UNIX95=1
# ps -efo vsz,sz,pid,args |grep -v grep | sort -rnk 1

These need to be on the same line:
$ UNIX95=EXTENDED_PS ps -efo vsz,sz,pid,args | sort -rnk 1

Memory leak detector might get you enough info to go with.
