# iostat: Sun Enterprise Server check - BB external script test
#
# version 1.0
# version 2.0 - now performs status check on vmstat results.
#               will now take over a minute and a half to run however.
# version 2.1 - now runs iostat in a more efficient manner
# version 2.2 - properly uses $CAT instead of cat
# version 2.3 - properly uses $MACHINE instead of `uname -n` in bb-hosts check
# version 2.4 - looks to see if $IOSTAT is set - for Linux mostly.
# version 2.5 - properly uses $THIS_HOST instead of $MACHINE due to fqdn using comma in name - thanks Craig Cook
# version 2.6 - properly works for HP-UX now
