System RAM memory

Paul Clayton — Mon, 18 Feb 2002 10:08:58 GMT

How do I find the total system ram memory installed. I need to parse the info to a script. SAM does not work for me, and swapinfo gives incorrect results.

Thanx

Try the following.

typeset -i mem=$(grep Physical /var/adm/syslog/syslog.log | awk '{print $7}')
echo $(hostname) has $mem bytes memory.+- $(( $mem /1024 )) mb

Hi,

what is your needed information?

--> systems total physical memory?

--> system memory + swapspace?

--> available swapspace only?

which output do you want, KB or MB?

please post what you want exactly.

Allways stay on the bright side of life!

Hi:

If a view of physical memory is what you seek, including DIMM sizes and arrangements, use this:

# echo "selclass qualifier memory;info;wait;infolog"|cstm > /tmp/meminfo

Hi,

Try this,

echo phys_mem_pages/D |adb /stand/vmunix /dev/mem

Hope this helps.

Hi,

If you want to find out the size of memory modules on your system, the slots being used, try this,

echo 'selclass qualifier memory;info;wait;infolog'|cstm >/tmp/meminfo.txt

Hope this helps.

P,

If you would like to script this... The easiest and most efficient way to do is:

To print on stdout:

awk -F ": " '/Ph/{print $3}' /var/adm/syslog/syslog.log | awk '{print $1}'

To capture it in a variable:

TOT_MEMORY=`awk -F ": " '/Ph/{print $3}' /var/adm/syslog/syslog.log | awk '{print $1}'`

Hope this helps !

If you have Ignite/UX installed here is another method. Though it is a bit slow, it will give you the output in MB.

RAM=`/opt/ignite/bin/print_manifest | grep "Main Memory" | awk '{ print $3 }'`

Hi,

Well, I think the print_manifest command actually parses the manifest file (also manifest.info)... so basically you could do this.. instead of running the print_manifest command (save some time :-))

TOT_MEMORY_MB=`awk '/Memory/{print $3}' /opt/ignite/data/tutorial/manifest`
