How to view the memory size (RAM size)

[senthil_kumar_1]

Hi

In HP-UX, how to view the memory size.

In linux i am using "# free -m". like this
what is the commnad used in HP-UX.

[Frank de Vries · Accepted solution]

swapinfo -m

or

top (12th line)

Memory: 826688K (466512K) real, 3096440K (2098204K) virtual, 176636K free Page# 1/17

or
vmstat 5 55 (5th collumn)

Hi Senthil,


check following commands...


# dmesg |grep -i Physical

#print_manifest |grep -i memory

Check with sam also as,

sam -> performance monitor -> system properties -> memory

[T G Manikandan]

# echo "selclass qualifier memory;info;wait;infolog"|cstm

this will give out the memory arrangment and slots in the board.

Hi,

you can check using glance
#glance -m

Senthil,

Use #print_manifest

(/opt/ignite/bin/print_manifest)

Check this link as well http://docs.hp.com/en/B2355-90772/ch05s06.html [Admin: This link is no longer valid]

Attached are some useful docs..

Hi:

If you are running an Itanium server, use :

# machinfo

[Hakki Aydin Ucar]

the following command also can be used:

dmesg | grep -E -i 'memory|physical'

[Avinash20]

If lot of diagnostic messages are being logged to system buffer, the dmesg wont be able to show your the Physical memory

Better way as suggest above is print_manifest or machinfo from the OS.

Hi,

Many ways you can find the physical memory details. Fews are,

# echo "selclass qualifier memory;info;wait;infolog" | /usr/sbin/cstm | grep 'Total Configured'
# echo "selclass qualifier memory;info;wait;infolog" | /usr/sbin/cstm | awk '/Total Configured/{print $5}'|head -1
# /opt/ignite/bin/print_manifest |grep i memory
# dmesg |grep -i physical
# grep Phys /var/adm/syslog/syslog.log

[Md. Farhan A Azam]

Hi,

1). Through SAM
#sam> Press "Return" to continue...> Performance Monitors> System Properties> Memory.

2). You can get it through kmeminfo (if kmeminfo is installed).
#cd /tmp
#./kmeminfo


Thnx...Farhan

hi,
I always do this below command to check my physical memory.

# dmesg |grep -i physical
or
machinfo
or

Hi,
# To get RAM size in KB
perl -e 'local($PSTAT,$PSTAT_STATIC,$mem_info,$PSTAT_STRUCT)=(239,2,"\0"x120,"LI4L");
syscall($PSTAT,$PSTAT_STATIC,$mem_info,length($mem_info),1,0);
print "RAM=".int((unpack($PSTAT_STRUCT,$mem_info))[4]*((unpack($PSTAT_STRUCT,$mem_info))[5])/(1024*1024))."\n";'

Hi,

# glance -m
sh: glance:  not found.

Not working.

You purchase glance separately.

(Try another of the above suggestions, except for dmesg.)

I manage a number of legacy HP-UX systems from HP-UX 9 to HP-UX 11 and not all have all toos/commands.

Thus I prefer something which works on all flavors.

dmesg does not give the answer if the system was up a long time and the buffer does not hold the boot information anymore. Kernel tools are different on different versions and support tools are often not installed.

Currently I use a combination of dmesg and syslog lookup and check for the Physical memory lines, which gives me a result in most cases.

   [[ -d /usr/adm        ]] && SYSLOGdir=/usr/adm
   [[ -d /var/adm/syslog ]] && SYSLOGdir=/var/adm/syslog
         dmesg | cat - $SYSLOGdir/*syslog* \
               | grep Physical: \
               | sed -e 's/.*ical: *//' -e 's/ .*//' \
               | sort -u | awk '{printf( "%d MB\n", $0/1024 )}'
