check_rasp_temp

Nagios-Plugin to check the CPU temperature of a Raspberry Pi

Installation

This example uses a Raspberry Pi with Raspbian Wheezy and a Nagios server running Debian Wheezy. You might want to use other thresholds, e.g. the Raspberry in our server room is normally running at ~43°C so I have set the threshold to 45°C.

Download Plugin

cd /usr/lib/nagios/plugins/ && \
wget https://raw.githubusercontent.com/larsen0815/check_rasp_temp/master/check_rasp_temp && \
chmod +x check_rasp_temp

Plugin needs to be run as root

cat <<EOF > /etc/sudoers.d/nagios_rasp_temp
nagios ALL=(root) NOPASSWD: /usr/lib/nagios/plugins/check_rasp_temp
EOF

Define NRPE command with thresholds

cat <<EOF > /etc/nagios/nrpe.d/rasp_temp.cfg
command[check_rasp_temp]=sudo -u root /usr/lib/nagios/plugins/check_rasp_temp -w 60 -c 70
EOF

Reload NRPE server

service nagios-nrpe-server reload

Define service on your Nagios host

define service{
        use                     generic-service
        hostgroup_name          raspberry-devices
        service_description     Temperature
        check_command           check_nrpe!check_rasp_temp
}

Reload Nagios server

service nagios3 reload

Test your new check on your Nagios server

/usr/lib/nagios/plugins/check_nrpe -H #Raspberry_IP# -c check_rasp_temp
