[Xymon] Memory utilization reporting for HP-UX 11.31 ia64

[innate.ideas]

Here is an updated script we use to report memory utilization on HP-UX 
11.31 ia64. The obnoxious part is that it requires a sudoer entry for 
the Xymon user to run /usr/bin/adb.

#!/usr/bin/ksh
#
#  This has been modified to compensate for ia64 reporting inaccuracy 
from swapinfo.  It does in the case of ia64 require a
#  sudo entry to allow the user to execute a /usr/bin/adb command.

# This script properly calculates memory values on HP-UX systems where 
memory
# page size has been increased. Tested on HP-UX 11iv3 Itanium with 8k, 
16k, and 64k
# memory page sizes.
#
#  This has been modified to compensate for ia64 reporting error from 
swapinfo.  It does in the case of ia64 require a
#  sudo entry to allow the Xymon user to execute a /usr/bin/adb command.
# sudoers entry something this should work: BB      ALL=NOPASSWD: 
/usr/bin/adb
#
#This script replaces the binary hpux-meminfo in client/bin directory.
