The adb command provides a way to gain useful information about a number of the
systems configuration areas.

To determine the physical memory (RAM) :

for HP-UX 10x
example:

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

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

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:
example:

echo phys_mem_pages/D | adb64 /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:
example:

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

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

echo total_lockable_mem/D |adb64 /stand/vmunix /dev/mem

To determine the number of free swap pages :
example:

echo swapspc_cnt/D | adb /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:
example:

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

To determine the number of processors in use:
example:

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

To determine the number of pages of buffer cache ( 4Kb in size)
example:
echo bufpages/D | adb /stand/vmunix /dev/mem
bufpages:
bufpages: 18848

To display kernel parameters using adb use the parameter name :
example:

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

To determine the amount of vxfs inodes in use
example:

echo vxfs_ninode/D | adb /stand/vmunix /dev/mem
vxfs_ninode:
vxfs_ninode: 64000

To determine the kernel you are booted from:
example:
10.x
echo 'boot_string/S' | adb /stand/vmunix /dev/mem
boot_string:
boot_string: disc(52.6.0;0)/stand/vmunix

11.x
example:

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
