how to get cpu info

[Basel Naamna]

How can I get cpu info from the command line,
I need to know number of cpu's and the speed of each.
i dont have root permission , (and dont have permission to /dev/kmem)
also i can't use a scripts (i need to run rexec query)

[Pedro Cirne]

Hi,

You may check the number of CPUs by using the top command.

You can also get some information using the command model

I got this script from here on itrc somewhere.

#!/bin/ksh
#
# @(#) sysinfo - gives system information on HPUX machine
#
echo `hostname` "is a " `model |sed 's/9000\/800\///' |sed 's/9000\/899\///'` "with" `/usr/sbin/ioscan -k |grep -n processor |wc -l` `/home/adm/bin/cpuspeed` "Mhz processors and" `/home/adm/bin/meminfo` "of memory"

[Mel Burslan]

perl -e 'local($PSTAT, $PSTAT_PROCESSOR)=(239,10);
local($struct_pst_processor)=("L30");
local($cpu_info
, $cpu_ticks);
$cpu_info = "\0" x 120;
syscall($PSTAT, $PSTAT_PROCESSOR, $cpu_info, length($cpu_info), 1, 0);
($cpu_ticks)=(unpack($struct_pst_processor
, $cpu_info))[26];
print "speed=".int($cpu_ticks/10000)."\n";'

this will give you the speed of cpu without root privileges.

if you need more info this may help you:

echo "map\nselect device 33\ninfo\nwait\nil\n" | /usr/sbin/cstm

here on this command you need to know your CPU line number on the cstm map, which was 33 for one of my 4 cpus. you can get it from the output of this command and process it yourself:

echo "map" | /usr/sbin/cstm

hope this helps

Without root - very very hard....

If you are not root - then why do you need to know?

If you can pursuade the admin - ask them to install sudo, then this script:

# 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 $hpux /dev/kmem | \
tr "\012" " " | \
read junk junk2 kval
}
hpux=/hp-ux
rev=$(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

If you are familiar with CSTM, you can run all the syntax from the command line with out have to enter into the utility.
you can get CPU, memory, Machine serial number, etc.

[Rick Garland]

The info you are requesting can be readily obtained from a Sys Admin who has the root access. Without root you will be performing lots of commands that will seem to be taking you in a circle.
If you have (or can get) sudo priviledges then you will have an easier time.


To determine CPU speed;
echo itickl_per_usec/D | adb /stand/vmunix /dev/kmem


To determine number of processors in use;
echo "runningprocs/D" | adb /stand/vmunix /dev/mem


To get CPU HW support;
getconf HW_CPU_SUPP_BITS


To get kernel support;
getconf KERNEL_BITS

[Brad Baron]

#echo "selall;info;wait;infolog;view;done" | cstm

[H.Merijn Brand (procura]

It's all in my FAQ [1], and you don't need root[2].

[1] http://mirrors.develooper.com/hpux/faq.html
[2] http://mirrors.develooper.com/hpux/ux

As most possibilities are already posted here, I'll just take the shortest non-root version from the FAQ to put here:

a5:/wrk 108 > perl -MUnix::Processors -le'print join"\t",$_->id,$_->state,$_->type,$_->clock for @{Unix::Processors->new()->processors}'
0 online HP PA-RISC 2.0 750
1 online HP PA-RISC 2.0 750
a5:/wrk 109 >

Enjoy, Have FUN! H.Merijn

You can use sam for this also (if specific use is added to access sam).

sam -> performance monitor -> system properties -> processor

If you use sysinfo or adb then it will be able to get information from adb only.

hth.

Hi Basel

1. top command will give you number of CPUs in server

2. with cstm>sel all > info > il you can get complete information on CPUs

3. You may also use third part utility "cfg2html" available from freeware

Hi Basel
Please find the attached script(created by some other irtcian) & change permission and run.
# ./ranveer

This will give u information.

enjoy
