finding info

khilari — Mon, 26 Feb 2007 11:15:27 GMT

Hi guys, i wanted to know how do u get to know how much memory an hp-ux system has. And also for network interface how do u find the speed and also if its duplex or not.Also, just want to confirm that the default route means the gateway right?. And lastly, netmask ffff8000 means 255.255.128.0 ?
Thanks

HI Khilari,

U can use swapinfo command to view your memory in hpux.

same time you can use print_manifest to view complete machine configuration.

Note this option only works if ignite is installed. Try it out.

Ther are several ways to get the info you want

SAM
Glance
dmesg

all the above will give you a part of the info you want

You can also download and run sysinfo from the attached site. It will give you all of the info you want, plus more, in a nicely fornatted report

You can use glance and go into the memory section (by bpressing m) to get the phyiscal memory

& yes netmask ffff8000 means 255.255.128.0

Hi Khilari,
There are many ways through which you will get information about memory.Following are some commonly preferred ways:
1]glance --> by using glance command you can check for the memory.
2]swapinfo -->swapinfo prints information about device and file system paging space
By default, swapinfo prints to standard output a two line header as shown here, followed by one line per paging area:
o/p-->
Kb Kb Kb PCT
TYPE AVAIL USED FREE USED

START/ Kb
LIMIT RESERVE PRI NAME

3]dmesg -->gives you physical,available & lockable memory in kbytes

4]print_manifest

5]machinfo --> provides another mechanism for reporting the amount of physical memory.

Reshma

Here's a script for lancards:

# cat /usr/local/bin/lancards
#!/usr/bin/sh
# script to check speed and settings of lan cards
PATH=/usr/sbin:/usr/bin
ppas=`lanscan | awk '$3~/^[0-9]$/{print $3}' | xargs`
for i in $ppas
do
printf "Card at PPA %s - " $i
ipa=`ifconfig lan${i} 2>/dev/null | awk '{ip=$2}END{if(ip==""){printf("Not assigned")}else{printf("%s ",ip)}}'`
printf "IP Address: %15s- " "$ipa"
lanadmin -x $i 2>/dev/null | awk '{$1="";printf("%s",$0)}'
echo ""
done

and one for memory:

# cat /usr/local/bin/hpmem
#!/bin/ksh
#
# Taken from the HP/UniGraphics FAQ
# You must be ROOT to execute this since it uses adb to
# examine the running kernel
#
GetKernelSymbol()
{
echo "$1/D" | \
adb $hpux /dev/kmem | \
tr "\012" " " | \
awk -F: '{print $3}'|\
read kval
}
hpux=/hp-ux
rev=$(uname -r | cut -d. -f2)
if ((rev > 9)); then hpux=/stand/vmunix ;fi
/bin/uname -a
# if 11iv2 or higher - get cpu this way
ver=$(uname -r | cut -d. -f3)
if ((ver > 22)); then
kval=`echo "processor_count/D" | adb /stand/vmunix /dev/kmem |tail -1|awk -F: '{print $2}' `
else
GetKernelSymbol "processor_count"
fi
print CPU Count: $kval
GetKernelSymbol "itick_per_tick"
let speed=kval/10000
print CPU Speed: $speed MHz
if ((rev > 10)); then
print CPU HW Support: `getconf HW_CPU_SUPP_BITS`-bit
print Kernel Support: `getconf KERNEL_BITS`-bit
GetKernelSymbol "memory_installed_in_machine"
else
GetKernelSymbol "physmem"
fi
# if 11iv2 or higher - get memory this way
ver=$(uname -r | cut -d. -f3)
if ((ver > 22)); then
kernel=$(/usr/sbin/kcpath -x)
hexval=$(echo "phys_mem_pages/A" | adb $kernel /dev/kmem|tail +2|awk '{print $2}')
REAL_MEM=$(echo ${hexval}=D|adb)
mb=$(expr ${REAL_MEM} / 256)
else
let mb=kval*4/1024 # convert pages to MB
fi
print RAM Size: $mb MB
GetKernelSymbol "bufpages"
let mb=kval*4/1024 # convert pages to MB
print bufpages: $mb MB
GetKernelSymbol "maxuprc"
print maxuprc: $kval
GetKernelSymbol "maxvgs"
print maxvgs: $kval
GetKernelSymbol "maxfiles"
print maxfiles: $kval
GetKernelSymbol "max_thread_proc"
print max_thread_proc: $kval
GetKernelSymbol "nfile"
print nfile: $kval
GetKernelSymbol "nproc"
print nproc: $kval
GetKernelSymbol "ninode"
print ninode: $kval
GetKernelSymbol "vfd_cw"
print shmmax: $kval
GetKernelSymbol "shmmni"
print shmmni: $kval
GetKernelSymbol "dbc_max_pct"
print dbc_max_pct: $kval

Or you can compile the attached c program called memdetail.

Hi,
to get memeory info you can use this Perl script from EACH user:

# 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";'

netmask ffff8000 means 255.255.128.0

HTH,
Art
