-# Nagios script to check network I/O status
-#
-# Copyright 2007, 2008 Ian Yates
-#
-# See usage for command line switches
-#
-# NOTE: Because of the method of gathering information, bytes/s values are calculated here, so no wanring/critical values can be set to trigger.
-#       Consequently, this check plugin always returns OK.
-#       This plugin is a means of returning stats to nagios for graphing (recommend DERIVE graph in RRD)
