Use of awk to filter out the command output

Hi All,

I am trying to find out number of cores present for hp-ux server from the output of print_manifest (as shown below). i suppose awk will be best tool to use for filtering.
output of print_manifest is :

PHP Code:


System Hardware
    Model:              ia64 hp Integrity Virtual Partition
    Main Memory:        6137 MB
    Processors:         2
        Intel(R)  Itanium(R)  Processor 9560 (2.53 GHz, 32 MB)
        8 cores, 16 logical processors per socket
        6.38 GT/s QPI, CPU version D0
               Active processor count:
               1 socket
               1 core
               2 logical processors (2 per socket)
               LCPU attribute is enabled

search should satisfy below conditions :
1. first it should check for presence of 'core' , this can be achived using

Code:

# print_manifest | grep -i "core"
        8 cores, 16 logical processors per socket
               1 core

now as the output shows , 8 cores are of physical machine on which this particular vm is built and 1 core is the actual number of cores assigned to this HP-UX vm. so can someone let me know how can i filter out only the numerical value that is 8 and 1

hostinfo

hostinfo(8)						    BSD System Manager's Manual 					       hostinfo(8)

NAME

     hostinfo -- host information

SYNOPSIS

     hostinfo

DESCRIPTION

     The hostinfo command displays information about the host system on which the command is executing.  The output includes a	kernel version
     description, processor configuration data, available physical memory, and various scheduling statistics.

OPTIONS

     There are no options.

DISPLAY

	   Mach kernel version:
	   The version string compiled into the kernel executing on the host system.

	   Processor Configuration:
	   The maximum possible processors for which the kernel is configured, followed by the number of physical and logical processors avail-
	   able.

	   Note: on Intel architectures, physical processors are referred to as cores, and logical processors are referred to as hardware threads;
	   there may be multiple logical processors per core and multiple cores per processor package.	This command does not report the number of
	   processor packages.

	   Processor type:
	   The host's processor type and subtype.

	   Processor active:
	   A list of active processors on the host system.  Active processors are members of a processor set and are ready to dispatch threads.
	   On a single processor system, the active processor, is processor 0.

	   Primary memory available:
	   The amount of physical memory that is configured for use on the host system.

	   Default processor set:
	   Displays the number of tasks currently assigned to the host processor set, the number of threads currently assigned to the host proces-
	   sor set, and the number of processors included in the host processor set.

	   Load average:
	   Measures the average number of threads in the run queue.

	   Mach factor:
	   A variant of the load average which measures the processing resources available to a new thread.  Mach factor is based on the number of
	   CPUs divided by (1 + the number of runnablethreads) or the number of CPUs minus the number of runnable threads when the number of
	   runnable threads is less than the number of CPUs.  The closer the Mach factor value is to zero, the higher the load.  On an idle system
	   with a fixed number of active processors, the mach factor will be equal to the number of CPUs.
