HP-UX 11iv3 memory reporting issue and fix

[Flack, Earl]

First I'd like to say thank you to Henrik and the other Xymon developers
for all their hard work on this program.

We are running Xymon 4.3.0 beta 2 client running on HP-UX 11iv3 Itanium
with non default (4k) memory page sizes. We discovered a problem with
Xymon memory reporting on HP-UX 11iv3 when we increased memory page
sizes from 4k to 16k or 64k.

The Xymon program hpux-meminfo located in ~client/bin has incorrect
reporting with HP-UX 11iv3 Itanium, for example:

On an HP-UX 11iv3 server with 32GB of memory (with about 15GB free) and
16k memory page size the hpux-meminfo program reports:

Total:8190   #Looks like the included hpux-meminfo grabs the wrong
output lines.
Free:3328

Here is the complete output of swapinfo -tm:

# swapinfo -tm

Xymon bug id #3134680


Here is a script we created to replace the hpux-meminfo binary that
comes with Xymon 4.3.0 beta 2.

------------------------------------------------------------------------
------------------------------

#!/usr/bin/ksh
# 10 DEC 2010 Daniel Grahek
# This script properly calculates memory values on HP-UX 11iv3 Itanium
systems 
#This script replaces the binary hpux-meminfo in client/bin directory.
#version 1.0
# Distributed under GPL v2 license.

FREE=`/usr/sbin/swapinfo |grep ^memory |awk {'print $4'}`
FREEREPORT=`echo $FREE / 1024 |/usr/bin/bc`
TOTAL=`/usr/sbin/swapinfo |grep ^memory |awk {'print $2'}`
TOTALREPORT=`echo $TOTAL / 1024 |/usr/bin/bc`
echo Total:$TOTALREPORT
echo Free:$FREEREPORT

The output from this script returns the following on the same system.

Total:32362
Free:14818
