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
|
|
```
