## What is Netdata data source plugin for Grafana?

Netdata’s data source plugin connects directly to our Netdata Cloud API’s, meaning that you’ll need to have your nodes (hosts) connected to [Netdata Cloud](https://app.netdata.cloud/?utm_source=grafana&utm_content=data_source_plugin) in order to be able to have them exposed on our plugin. For security purposes you will also need an API token for authentication (which you can get from within your Netdata profile).

## How to install the plugin?

To start using the Netdata data source plugin on your Grafana environment, local or Cloud, you need to install the plugin manually - it currently isn't signed. Here are some tips to get through this depending on your setup:
* Docker
* Linux (local)
* Windows (local)
* Building the plugin locally

### Docker

#### Pre-buit script - setup-demo-environment
We provide you a script `setup-demo-environment.sh` that will help you setting this up real fast.
To start the container with the Netdata datasource plugin already installed you just need to:
> `setup-demo-environment.sh run`

To remove container:
> `setup-demo-environment.sh remove`

This script will:
1. Spin up a grafana container without starting grafana itself
1. Retrieve the latest available release of the Netdata datasource plugin
1. Install the Netdata datasource plugin in /var/lib/grafana/plugins
1. Start grafana

#### Manual step-by-step

1. Setup your grafana docker container with the the permissions to load netdata plugin as unsinged

`docker run -d --env GF_PLUGINS_ALLOW_LOADING_UNSIGNED_PLUGINS=netdata-datasource --name=grafana grafana/grafana`

2. Ensure you have the desired version of the plugin you want to install, get it from github releases

```curl -s https://api.github.com/repos/netdata/netdata-grafana-datasource-plugin/releases/latest \
jq -r '.assets[] | select(.name|match("zip$")) | .browser_download_url'
```

3. Grafana plugins, by default, should be under /var/lib/grafana/plugins. Create a folder for netdata inside the container. Enter in an interactive session

`docker exec -ti grafana bash`
`mkdir /var/lib/grafana/plugins/netdata`

4. Copy the contents of the Netdata data source plugin to the new plugin folder created on step 2

`unzip netdata-datasource-<version_number>.zip`
`docker cp netdata-datasource grafana:/var/lib/grafana/plugins/netdata/`

### Linux (local)

1. Ensure you have the desired version of the plugin you want to install, get it from github releases

```curl -s https://api.github.com/repos/netdata/netdata-grafana-datasource-plugin/releases/latest \
jq -r '.assets[] | select(.name|match("zip$")) | .browser_download_url'
```

2. Grafana plugins, by default, should be under /var/lib/grafana/plugins. Create a folder for netdata

`mkdir /var/lib/grafana/plugins/netdata`

3. Copy the contents of the Netdata data source plugin to the new plugin folder created on step 2

`unzip netdata-datasource-<version_number>.zip`
`cp -rf netdata-datasource/ /var/lib/grafana/plugins/netdata`

4. Ensure that Netdata plugin which currently isn’t signed can be registered

`vi /etc/grafana/grafana.ini`

On `allow_loading_unsigned_plugins` entry add **netdata-datasource**

`allow_loading_unsigned_plugins = netdata-datasource`

5. After adding the plugin a restart of grafana server is needed

For init.d based services you can use the command:
`sudo service grafana-server restart`

For systemd based services you can use the following:
`systemctl restart grafana-server`

### Windows (local)

1. Ensure you have the desired version of the plugin you want to install, get it from github releases

```curl -s https://api.github.com/repos/netdata/netdata-grafana-datasource-plugin/releases/latest \
jq -r '.assets[] | select(.name|match("zip$")) | .browser_download_url'
```

2. Grafana plugins, by default, should be under C:\Program Files\GrafanaLabs\grafana\data\plugins. Create a folder for netdata

`mkdir ‘C:\Program Files\GrafanaLabs\grafana\data\plugins\netdata’`

3. Copy the contents of the Netdata data source plugin to the new plugin folder created on step 2

`wzunzip -d netdata-datasource-<version_number>.zip`
or
`gzip -d < netdata-datasource-<version_number>.zip `
`cp .\netdata-datasource\* "C:\Program Files\GrafanaLabs\grafana\data\plugins\netdata"`

4. Ensure that Netdata plugin which currently isn’t signed can be registered

`notepad ‘C:\Program Files\GrafanaLabs\grafana\conf\default.ini’`

On `allow_loading_unsigned_plugins` entry add **netdata-datasource**

`allow_loading_unsigned_plugins = netdata-datasource`

5. After adding the plugin a restart of grafana server is needed

`net stop Grafana`
`net start Grafana`

### Building the plugin locally

For any of the above steps if you prefer to build this plugin locally instead of retrieving it from from the releases you can:

1. Clone this repo
`git clone https://github.com/netdata/netdata-grafana-datasource-plugin`

2. Build it locally
`yarn`
`yarn build`

3. Place the contents of the `/dist` folder under the netdata folder in Grafana plugins directory.
