Hi jlliagre!

First, thanks for responding!

So taking from your response,
The "iowait" and "swap" CPU state are items I should not worry about

I can use the vmstat "free" column for "Free" physical memory, but how do I test
for the total Physical memory?

I have checked and like the results from "swap -l". Thank you!

In the end, I don't want one single utility to do this. Or rather, once I understand how to get what I want I can build my script which will be the "one single utility" I use and can share.

Ultimately, the output needs to be:
Box Name, Mar-20-13,10:45:05,97.5%,10G,4473M,9083M,9083M,0.06, 0.05, 0.05
Where:
97.5% = CPU Idle [ This I still need * See below* ]
10G = Total phys memory [ This I can get from "vmstat 1 1" per your reply ]
4473M = Phys Memory in use [ This I still need ]
9083M = total Swap [ This and the next I can get from "swap -l" per your reply ]
9083M = Swap in us (this is a lab machine for design)
0.06, 0.05, 0.05 is the cpu load [This I can get from "prstat 1 1"]

Regarding the CPU Idle,
Top shows "97.5%"
where vmstat shows "83", being 83 percent.

Is this just an artifact of top not being accurate in a Solaris OS or is there something I am missing?

And on the "Phys Memory in use", how do I get that?
I am researching this, but came here when I found myself trying to read up on vmstat, prstat, kstat and several other things all at the same time. If I had one path, I could walk it myself. But I need direction on which to use or I'll be balancing on a toe each as I walk many paths rather than walking one with both feet

Thanks for your help.

An additional discovery I've made is that:
vmstat 1 1
gives a "free" of 5001808
where
kstat -n system_pages | grep availrmem
gives a "availrmem" of 1207874

So as I continue to research, I am finding that each of the roads I am walking give answers which appear similar but are vastly different

With help from you folks and my own research I found:

/usr/sbin/prtdiag | grep "Memory size" | awk '{print $3}'
gets me Phys memory size

/usr/bin/vmstat 1 1 | grep -v free | grep -v faults | awk '{print $5}'
gets me Phys Memory free

prstat 1 1 | grep load | awk '{print $8, $9, $10}'
gets: me the load averages

/usr/sbin/./swap -l
gets:me the swap size and free

/usr/bin/vmstat 1 1 | grep -v swap | awk '{print $22}'| sed '/^$/d'
gets me the CPU Idle

Thanks for the guidance!!!!

xsysinfo

XSYSINFO(1x)							 Debian GNU/Linux						      XSYSINFO(1x)

NAME

       xsysinfo - Display Linux kernel parameters in graphical form

SYNOPSIS

       xsysinfo [-help] [-update n] [-[no]title] [-[no]labels] [-[no]loadavg] [-[no]load] [-[no]mem] [-[no]swap] [-[no]smp]

DESCRIPTION

       Xsysinfo  is  an  X application to display some Linux kernel parameters in graphical form. It is like a mix of top, free and xload with the
       difference that the values are shown in form of a horizontal bar. The displayed values are: CPU load average, CPU  load,  memory  and  swap
       sizes (details see below).

OPTIONS

       -update n
	      Set update rate to n milli-seconds

       -title Show title string

       -notitle
	      Don't show title string

       -labels
	      Show gauge labels

       -nolabels
	      Don't show gauge labels

       -loadavg
	      Show CPU load average value

       -noloadavg
	      Don't show CPU load average value

       -load  Show CPU load value

       -noload
	      Don't show CPU load value

       -smp   Show separate SMP loads

       -nosmp Don't show separate SMP loads.

       -mem   Show memory info

       -nomem Don't show memory info

       -swap  Show swap info

       -noswap
	      Don't show swap info

       -help  Display options

DISPLAY

       Xsysinfo display the following values:

       CPU load average
	      CPU load average between 0.000-8.000. The gauge's bar is subdivided into segments, where one segment represents a load value of 1.0.
	      The bar's full length is automatically scaled, depending on the displayed value.

       CPU load
	      percentage CPU load time to CPU idle time subdivided in three segments: user load, system load and nice load. On an SMP  system  the
	      -smp option replaces the single total load meter with a separate meter for each processor.

       Memory The  memory  gauge's  bar is subdivided into two segments with the amount of physical memory, which is used by processes on the left
	      and physical memory used for the page and buffer cache on the right. The length of the whole bar, which is the sum of these two val-
	      ues, shows the amount of physical memory currently used by the system.

       Swap   The percentage of swap space used by the system to total amount of swap space.
