# HP-UX port from original cpu plugin, here using sar instead of
# Solaris' kstat. Also note that kstat as well as Linux /proc/stat
# use counters (of cpu cycles?), whereas sar merely displays
# percentages (hopefully this comes close enough)
#
# Customizations. The values shown here are the defaults
#
# [sar_cpu]
# env.SYSWPCT 30 # System percentage to warn at
# env.SYSCPCT 50 # System percentage where we're critical
# env.USRWPCT 80 # User percentage to warn at
# env.scaleto100 1 # Graph in percent rather than absolute ncpu
#
# Contributed by <ralph dot grothe at itdz minus berlin dot de>
