# Install Telegraf

Install and configure Telegraf

```java
sudo docker pull telegraf
```

Create a default configuration

```
sudo docker run --rm telegraf telegraf config > telegraf.conf
```

* Do the configuration on telegraf.conf and search for "mqtt\_consumer" and add/modify the following lines:

```
server = ["tcp://raspberry_pi_ip:1883"]
topics = [
  "sensors"
]
data_format = "influx"
```

**Note:** "raspberry\_pii\_ip" is the actual ip address of the raspberry PI. You can check its IP by going to the terminal on raspberry pi command line "ifconfig" and find for "inet addr". 

* Then, look for outputs.influxdb and add/modify the following lines

```
urls = ["http://raspberry_pi_ip:8086"]
database = "sensors"
skip_database_creation = true
username = "telegraf"
password = "telegraf"
```

**Note:** The output file normally is located in "/home". Open that file and do the modification above. Don't forget to un-command the line that is modified. Otherwise, it won't work. 

* Finally, run Telegraf

```
sudo docker run -v /home/pi/:/etc/telegraf:ro telegraf
```
