#   check-environmentals
#
# DESCRIPTION:
#   Send a Warning message if an environmental sensor is
#   more than the warning threshold.
#   Send a critical message if sensor is beyond critical threshold.
#   Event is sent on first match. So if multiple environmental sensors
#   could trigger event, only the first found event will be seen in
#   the trigger event output
#   Send an event if minimum number of working fans is
#   less than --min-fans
#
# OUTPUT:
#   plain text
#
# PLATFORMS:
#   Cumulus Linux
#
# DEPENDENCIES:
#   gem: sensu-plugin
#
# USAGE:
#  Set warning threshold to 85% and critical threshold to 97%
#  So if the max Fan speed is 12000 RPM and current fan speed is 11900 RPM
#  a critical event is sent because current fan speed is
#  greater than 97% of max recommended fan speed.
#  Minimum number of fans working is 2. anything lower i
#  and an alert is issued.
#   ./check-environmentals -w 85 -c 97 --min-fans 2
