[Xymon] hpux-meminfo.c patch

[Flack, Earl]

Those work for physical memory in many cases but we are looking for a
command to determine how much memory is being consumed.

Here are some ideas that might be fruitful.

# dmesg | grep Physical   (works on all HP-UX from 11.00 onwards)

# print_manifest | grep -i memory  (I'd use this as a last resort, as
the manifest is created at factory and mightn't include field upgrades)

# machinfo | egrep "^Memory"

If you are on a cell based server, you can use the /usr/sbin/parstatus
command to get detailed information about your overall memory
configuration by cell board, partition, etc.

So the bad news is that swapinfo (on HP-UX 11iv3 ia64 at least) does not
take into account shared memory space memory utilization. 

We orginally tested the script on some idle servers with no databases
running at the time and it looked good there. After starting up a bunch
of oracle databases the output did not look right. Further investigation
showed that swapinfo was reporting an incomplete picture of memory, we
compared with kmeminfo and glance. Back to the drawing board for
scripts.
