What is the best command to determine physical memory of a system?

[James R. Ferguson]

Hi:

# top
# dmesg
# glance
# grep -i physical /var/adm/syslog/OLDsyslog.log

...JRF...

[Frances Prindle]

We have tried all of these commands and have come up with as many different answers. How is it determined which is the TOTAL USABLE PHYSICAL MEMORY

[Curtis Larson]

got diagnostics?

echo "sc product MEMORY;info;wait;infolog\ndone\n" | cstm

might need a different syntax for different version of diagnostics. So if product isn't correct syntax try type instead.

depending on what information you want, this will give some good numbers
echo "..." |cstm |
awk '/Memory Board Inventory/ {
flag=1;
}
/Memory Controller Inventory/ {
exit;
}
{if ( flag == 1 ) print $0;} '

if your not interested in details:
/usr/sam/lbin/getmem

[Bill Hassell]

Of the tools:

# top
Never have figured out what those numbers mean exactly...installed physical memory is not reported though

# dmesg
Only works if your console has not pushed the information off the top of the incore buffer.

# glance
glance -m works every time. The Phys Mem reports installed memory.

# grep -i physical /var/adm/syslog/OLDsyslog.log
Should work but often fails because a cron job is truncating syslog.

# /usr/sam/lbin/getmem
Doesn't seem to provide the correct info for 11.0 and 11i

Here's a simple script to ask the kernel:

MAJOREV=$(uname -r|cut -f 2 -d .)
if [ $MAJORREV -ge "11" ]
then
MYSYMBOL="phys_mem_pages"
else
MYSYMBOL="physmem"
fi

MYMEM=$(echo "${MYSYMBOL}/D" | adb /stand/vmunix /dev/kmem | grep "${MYSYMBOL}: *." | awk '{print int($2*4/1024+.5)}')

echo $MYMEM

The question is can SAM do it ? or better why SAM did not do it?.
