Memory Usage(Physical) in one Word? Suse Linux.

Experts,

I have been trying to figure out what is the total physical memory used from this output:
And what is the free memory available for the application or any programs.


The answer has to be in this format:
1. Physical Memory Used= xx.xx%
2. Physical Memry available= yy.yy%

Can any one answer this question please.,


DATA: (output of free command ) :
######
OS=Suse Linux 11.

Code:
             total       used       free     shared    buffers     cached
Mem:      12200000   12003044     196956          0         52     524220
-/+ buffers/cache:   11478772     721228
Swap:     20955132     802368   20152764


I figured this means the Memory Usage= used/total * 100 = 98.3%







- Since The Usage (in sar) showing 98.45% it is high time to wake up and to be alert.
Since this is closed to full capacity, and things can start breaking if not paid enough attention to the usage.


# from sar -r : What I am seeing is below:
Code:
           kbmemfree kbmemused  %memused kbbuffers  kbcached  kbcommit   %commit
05:24:01 PM    188908  12011092     98.45        52    494044  15664476     47.25
05:25:02 PM    186124  12013876     98.47        52    494524  15669836     47.26
05:26:01 PM    187284  12012716     98.46        52    496068  15664196     47.25
05:27:01 PM    180372  12019628     98.52        52    496712  15664384     47.25
Average:       186109  12013891     98.47       500   2123739  15654751     47.22


-So I am trying to ask the experts what is the opinion about it , and if one can answer in a simple answer to this question: (Descriptive answer is welcome but I also want answer to 1. & 2.
I have a feeling like this is not real usage, so checking with linux experts.,

1. Physical Memory Used= xx.xx%
2. Physical Memry available= yy.yy%


Thank you for your time...

set_color(1)                                                           fish                                                           set_color(1)

NAME
set_color - set_color - set the terminal color set_color - set the terminal color Synopsis set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR] Description Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple, cyan, white and normal. o -b, --background Set the background color o -c, --print-colors Prints a list of all valid color names o -h, --help Display help message and exit o -o, --bold Set bold or extra bright mode o -u, --underline Set underlined mode o -v, --version Display version and exit Calling set_color normal will set the terminal color to whatever is the default color of the terminal. Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey font color, while set_color --bold white will result in a white font color. Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator. set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of ncurses and recompile fish against it in order to fix this issue. Version 1.23.1 Sun Jan 8 2012 set_color(1)
