# 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}
```
