check_temp.pl

Project Notes

This plugin can be used with NRPE or on a local machine.
It has been tested with sensor output in several forms:
#{1,3}
#{1,3}.#
#{1,3}.##

It will also match $sensor[newline]$temp where $sensor is the value of the -s argument.

## NRPE example ##
/etc/nagios/nrpe.cfg
command[check_temp]=/usr/lib/nagios/plugins/check_temp.pl -c 85 -w 75 -s 'CPU ., Core .'

/etc/sensors.conf
chip "coretemp-isa-0000"
label temp1 "CPU 0, Core 0"

chip "coretemp-isa-0001"
label temp1 "CPU 0, Core 1"

chip "coretemp-isa-0002"
label temp1 "CPU 0, Core 2"
