1)you mean if i add RSS column values i can get how much physical memory consumed
This will give you the sum of physical memory used by the userland processes, not the overall sum of physical memory used. The kernel and other entities make use of RAM too.
If you want a detailed view of RAM usage, run this command:

2)as you said from vmstat command the column free will give us free ram avabilable and what is column that swap indicate and this sizes are in kbytes??
Hi Guru's,
Since Iam learning Solaris 10 and want to instal it on to my computer in which 'Windows' is already installed. Also many other applications including Oracle, Java etc,. were also installed associated with Windows.
Now how can I install Solaris 10 on my system with out affecting my... (4 Replies)
I need some information for the top statistics being displayed in Solaris 10
they look like the following
CPU states: 92.0% idle, 3.3% user, 4.7% kernel, 0.0% iowait, 0.0% swap
Memory: 8192M real, 216M free, 9208M swap in use, 1236M swap free
I need to know what does 0.0% swap means.... (1 Reply)
Hi folks,
Sorry to barge in and ask a question right off the bat without contributing first.
I have a V440, 4 X 1GHZ, 32GB ram, and recently syslogd has started showing 30+ % cpu usage. It's also repeating entries in the syslog, over and over.
the /var/log/syslog file had grown to over 2GB - I... (2 Replies)
Ever noticed that using the top command on a multiple cpu box can often give totally misleading answers, like 230%, when you think that 100% should be the max?
Well, that's because top has a bizarre mode called "Irix mode" wherein if you have 4 cpus, the %CPU column of top can go up to 400%. I... (1 Reply)
I am changing jobs and need to know a little about Solaris specific commands. I come from AIX and we have commands like errpt, smit, and lsattr that are AIX specific.
Any help is appreciated. (4 Replies)
Hi all,
I found like top command could be used to find the Memory and CPU utilization. But i want to know how to find the Memory and CPU utilization for a particular user using top command.
Thanks in advance.
Thanks,

FREE(1) User Commands FREE(1)NAME
free - Display amount of free and used memory in the system
SYNOPSIS
free [options]
DESCRIPTION
free displays the total amount of free and used physical and swap memory in the system, as well as the buffers and caches used by the ker-
nel. The information is gathered by parsing /proc/meminfo. The displayed columns are:
total Total installed memory (MemTotal and SwapTotal in /proc/meminfo)
used Used memory (calculated as total - free)
free Unused memory (MemFree and SwapFree in /proc/meminfo)
shared Memory used (mostly) by tmpfs (Shmem in /proc/meminfo, available on kernels 2.6.32, displayed as zero if not available)
buffers
Memory used by kernel buffers (Buffers in /proc/meminfo)
cached Memory used by the page cache (calculated as Cached - Shmem in /proc/meminfo - the Cached value is actually the sum of page cache
and tmpfs memory)
OPTIONS -b, --bytes
Display the amount of memory in bytes.
-k, --kilo
Display the amount of memory in kilobytes. This is the default.
-m, --mega
Display the amount of memory in megabytes.
-g, --giga
Display the amount of memory in gigabytes.
--tera Display the amount of memory in terabytes.
-h, --human
Show all output fields automatically scaled to shortest three digit unit and display the units of print out. Following units are
used.
B = bytes
K = kilos
M = megas
G = gigas
T = teras
If unit is missing, and you have petabyte of RAM or swap, the number is in terabytes and columns might not be aligned with header.
-c, --count count
Display the result count times. Requires the -s option.
-l, --lohi
Show detailed low and high memory statistics.
-o, --old
Display the output in old format, the only difference being this option will disable the display of the "buffer adjusted" line.
-s, --seconds seconds
Continuously display the result delay seconds apart. You may actually specify any floating point number for delay, usleep(3) is
used for microsecond resolution delay times.
--si Use power of 1000 not 1024.
-t, --total
Display a line showing the column totals.
--help Print help.
-V, --version
Display version information.
