Nagios Plugin check_temperature

check_temperature - monitors the hardware's temperature

[/etc/nrpe.d/check_temperature]
command[check_temp_zone0]=/usr/lib/nagios/plugins/check_temperature -t 0 -w 80 -c 90

Usage note

This plugin monitors the hardware's temperature.
It requires the sysfs tree /sys/class/thermal to be mounted and readable.

Usage:
  check_temperature [-f|-k] [-t <thermal_zone_num>] [-w COUNTER] [-c COUNTER]
Options:
  -f, --fahrenheit  use fahrenheit as the temperature unit
  -k, --kelvin      use kelvin as the temperature unit
  -l, --list        list all the thermal sensors reported by the kernel
  -t, --thermal_zone    only consider a specific thermal zone
  -w, --warning COUNTER   warning threshold
  -c, --critical COUNTER   critical threshold
  -h, --help      display this help and exit
  -V, --version   output version information and exit
Note:
  If the option '-t|--thermal_zone' is not specified, then the thermal zone
  with the highest temperature is selected. Note that this zone may change
  at each plugin execution.
Examples:
  check_temperature --list
  check_temperature -w 80 -c 90
  check_temperature -t 0 -w 80 -c 90
