Memory utilization reporting for HP-UX 11.31 ia64

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.

# sudoers entry something this should work: BB      ALL=NOPASSWD: /usr/bin/adb
