# Raspberry Pi

Fluent Bit is distributed as **td-agent-bit** package and is available for the Raspberry, specifically for [Raspbian 8](http://raspbian.org). This stable Fluent Bit distribution package is maintained by [Treasure Data, Inc](https://www.treasuredata.com).

## Server GPG key

The first step is to add our server GPG key to your keyring, on that way you can get our signed packages:

```
$ wget -qO - https://packages.fluentbit.io/fluentbit.key | sudo apt-key add -
```

## Update your sources lists

On Debian and derivated systems such as Raspbian, you need to add our APT server entry to your sources lists, please add the following content at bottom of your **/etc/apt/sources.list** file:

#### Raspbian 9 (Stretch)

```
deb https://packages.fluentbit.io/raspbian/stretch stretch main
```

#### Raspbian 8 (Jessie)

```
deb https://packages.fluentbit.io/raspbian/jessie jessie main
```

### Update your repositories database

Now let your system update the _apt_ database:

```bash
$ sudo apt-get update
```

## Install TD-Agent Bit

Using the following _apt-get_ command you are able now to install the latest _td-agent-bit_:

```
$ sudo apt-get install td-agent-bit
```

Now the following step is to instruct _systemd_ to enable the service:

```bash
$ sudo service td-agent-bit start
```

If you do a status check, you should see a similar output like this:

```bash
sudo service td-agent-bit status
● td-agent-bit.service - TD Agent Bit

```

The default configuration of **td-agent-bit** is collecting metrics of CPU usage and sending the records to the standard output, you can see the outgoing data in your _/var/log/syslog_ file.
