# raspberrypi-temperature-telegraf
|
||
|
|
Collect RaspberryPi CPU and GPU temperature with telegraf
|
||
|
|
|
||
|
|
### How to use (No script required :fire:)
|
||
|
|
1. Add this to you telegraf.conf
|
||
|
|
```
|
||
|
|
[[inputs.file]]
|
||
|
|
files = ["/sys/class/thermal/thermal_zone0/temp"]
|
||
|
|
name_override = "cpu_temperature"
|
||
|
|
data_format = "value"
|
||
|
|
data_type = "integer"
|
||
|
|
|
||
|
|
[[inputs.exec]]
|
||
|
|
commands = [ "/opt/vc/bin/vcgencmd measure_temp" ]
|
||
|
|
name_override = "gpu_temperature"
|
||
|
|
data_format = "grok"
|
||
|
|
grok_patterns = ["%{NUMBER:value:float}"]
|
||
|
|
|
||
|
|
```
|
||
|
|
2. Add telegraf user to video group ```sudo usermod -a -G video telegraf```
|
||
|
|
3. ```sudo service telegraf stop;sudo service telegraf start```
|
||
|
|
4. Run test ```telegraf -config /etc/telegraf/telegraf.conf -test```
|
||
|
|
|
||
|
|
### How to use (Old way)
|
||
|
|
1. Copy ```telegraf_pi_temp.sh``` to ```/usr/local/bin/telegraf_pi_temp.sh```
|
||
|
|
2. Modify file permissions ```chmod +x /usr/local/bin/telegraf_pi_temp.sh```
|
||
|
|
3. Add ```telegraf``` user to video group ```sudo usermod -a -G video telegraf```
|
||
|
|
4. ```sudo service telegraf restart``` or ```sudo reboot```
|
||
|
|
5. Add to your telegraf.conf snippet from ```telegraf.conf```
|
||
|
|
6. Run test ```telegraf -config /etc/telegraf/telegraf.conf -test```
|
||
|
|
|
||
|
|
### Data format
|
||
|
|
To get a human readable *cpu* temperature divide it by 1000 (in grafana use the math(/ 1000) function
|
||
|
|
```json
|
||
|
|
{"cpu":54768, "gpu":54.8}
|
||
|
|
```
