Script to determine number and size of CPU's

[Penni Nussbaum]

I need to write a script (assuming Glance and stm is not installed on the server) to determine the number and size of the CPU's. I could get the size of the CPU from the model type, but how would I detremine the number of CPU's?

Hi .. Hope this helps

##Number of processors

sar -Mu 1 1|awk 'END {print NR-5}'


ioscan -kfnC processor


###To obtain the processor speed (MHz):

echo itick_per_usec/D|adb -k stand/vmunix /dev/kmem|awk 'NR==2 {print}'

or

echo itick_per_usec/D | /usr/bin/adb -k /stand/vmunix /dev/kmem



##total of memory

#!/bin/ksh
if [ `uname -r` = "B.11.00" ]
then
echo "phys_mem_pages/D" | adb /stand/vmunix /dev/kmem|grep phys|tail -1|awk '{print $2/256 " MB"}'
else
echo "physmem/D" | adb /stand/vmunix /dev/kmem|grep phys|tail -1|awk '{print "Memory size = " $2 / 256 " Megabytes"}'
fi

ioscan -fnkC processor | grep proc | wc -l

for number..

model is a good start to guess cpu speed without stm..
alternatively try /opt/ignite/bin/print_manifest

Later,

hi ,

maybe you could try the following
echo runningprocs/D | adb -k /stand/vmunix /dev/mem

hi,

if u have ignite installed
to get the no. of cpus
issue
/opt/ignite/bin/print_manifest |grep Processors

regds

If you have top - you could run top -d 1 (assumming you dont need to extract the values).

Many ways


dmesg | grep Proc | wc -l

sam---> performance moniotor-->System properties

print _manifest

Here's pretty much everything you ever wanted to know:
echo `hostname` "is a " `model |sed 's/9000\/800\///' |sed 's/9000\/899\///'` "w
ith" `ioscan -k |grep -n processor |wc -l` `/nfs/yukon/apps/hols/bin/ts/cpuspeed
` "Mhz processors and" `/nfs/yukon/apps/hols/bin/ts/memory` "KB of memory"

My apologies, that didn't paste very well. It ought to look something like this:
echo `hostname` "is a " `model |sed 's/9000\/800\///' |sed 's/9000\/899\///'` "with" `ioscan -k |grep -n processor |wc -l` `cpuspeed`
` "Mhz processors and" `memory` "KB of memory"

cpuspeed:
HPUX=/stand/vmunix

MHZ=$(echo itick_per_tick/D | adb -k $HPUX /dev/kmem | tail -1 | awk '{print $2/10000}')
echo $MHZ

memory:
HPUX=/stand/vmunix
MAJORREV=$(uname -r | cut -f2 -d .)
if [ $MAJORREV -ge "11.0" ]
then
MYSYMBOL="phys_mem_pages"
else
MYSYMBOL="physmem"
fi

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


At least I hope this is going to be more readable.
