# DESCRIPTION:
#   This plugin uses uptime to collect load metrics
#   Basically copied from sensu-community-plugins/plugins/system/vmstat-metrics.rb
#
#   Load per processor
#   ------------------
#
#   Optionally, with `--per-core`, this plugin will calculate load per
#   processor from the raw load average by dividing load average by the number
#   of processors.
#
#   The number of CPUs is determined by reading `/proc/cpuinfo`. This makes the
#   feature Linux specific. Other OSs can be supported by adding OS # detection
#   and a method to determine the number of CPUs.
#
# OUTPUT:
#   metric data
#
# PLATFORMS:
#   Linux, BSD, Solaris, etc
#
# DEPENDENCIES:
#   gem: sensu-plugin
#   gem: socket
