Here is what I have from someone else. I saved this info in my docs. It is very useful.
adb is a debugger.

Here are some commands to verify system resources:
for HP-UX 10x
echo physmem/D | adb -k /stand/vmunix /dev/kmem
physmem:
physmem: 24576

for HP-UX 11.x systems running on 32 bit architecture:

echo phys_mem_pages/D | adb /stand/vmunix /dev/kmem
phys_mem_pages:
phys_mem_pages: 24576

for HP-UX 11.x systems running on 64 bit architecture:

echo phys_mem_pages/D | adb64 -k /stand/vmunix /dev/mem
phys_mem_pages:
phys_mem_pages: 262144

The results of these commands are in memory pages, multiply by 4096
to obtain the size in bytes.

To determine the amount of lockable memory:

echo total_lockable_mem/D | adb -k /stand/vmunix /dev/mem
total_lockable_mem:
total_lockable_mem: 185280

To determine the number of free swap pages :

echo swapspc_cnt/D | adb -k /stand/vmunix /dev/kmem
swapspc_cnt:
swapspc_cnt: 216447

This will display the number of free swap pages.
Multiply the number returned by 4096 for the number of free swap bytes.

To determine the processor speed:

echo itick_per_usec/D | adb -k /stand/vmunix /dev/mem
itick_per_usec:
itick_per_usec: 360

To determine the number of processors in use:

echo "runningprocs/D" | adb -k /stand/vmunix /dev/mem
runningprocs:
runningprocs: 2

To determine the number of pages of buffer cache ( 4Kb in size)

echo bufpages/D | adb -k /stand/vmunix /dev/mem
bufpages:
bufpages: 18848

To display kernel parameters using adb use the parameter name :

echo nproc/D | adb -k /stand/vmunix /dev/mem
nproc:
nproc: 276

To determine the kernel your booted from:

10.x
echo 'boot_string/S' | adb /stand/vmunix /dev/mem
boot_string:
boot_string: disc(52.6.0;0)/stand/vmunix

11.x
echo 'boot_string/S' | adb /stand/vmunix /dev/mem
boot_string:
boot_string: disk(0/0/2/0.6.0.0.0.0.0;0)/stand/vmunix

Let patel know
this post was helpful!

# and CPU speed
echo itick_per_usec/D | adb /stand/vmunix /dev/kmem

For more options
#man getconf
#man sysconf
