Find Swap usage on Solaris

In Solaris, swap and physical memory can be interchanged, that is physical memory can be
reserved for swap instead of using the swap device. 

1. swap -lh
2. swap -sh
3. prtconf | grep size
4. ps -A -o vsz,rss | awk 'BEGIN {size = 0; rss = 0;} {size += $1; rss
+= $2} END{printf("Size = %d kb, RSS = %d kb\n", size, rss);}'

The first shows how much of the physical swap device has been used.  The
second looks at how much swap is used and reserved, versus available.
The third is just a sanity check for the physical memory.  The fourth
looks at all of the processes in the system and allows us to see the
total difference between the vsize and the rss.


Now to figure out per process usage of swap space, we can do the following


1) bash-3.00$ top -b -o size
load averages:  2.99,  2.94,  3.02;                    up 199+21:07:21 12:06:32
103 processes: 99 sleeping, 4 on cpu
CPU states: 88.7% idle,  9.0% user,  2.3% kernel,  0.0% iowait,  0.0% swap
Memory: 64G phys mem, 4834M free mem, 16G total swap, 16G free swap

looks like pid 12510 is using most virtual memory.. to figure out how much of i
is swap, use pmap's help

2) bash-3.00$ pmap -S 12510 | tail -1
total Kb 2368032 2022672

PID 12510 is using 2.02G of swap.
