## Run

Just run the compose file:

```

$ docker-compose up -d .

```

## Run (in Rancher)

Just paste the two from this repository configs (`docker-compose.yml` and `rancher-compose.yml`) to your monitoring stack and fire it up. Optionally you can change the `API key` to your needs.

## Autoscaling and control

The scaling of netdata master and slave services (containers) is loosely based on labels in rancher.

![Rancher monitoring stack](images/rancher-monitoring-stack.png)

A node inheriting the label `monitoring-slave = true` will start a monitoring slave (ephemeral node) and a node containing `monitoring-master`will start a master netdata (container).

![Rancher monitoring stack (hosts view)](images/rancher-monitoring-stack-hosts.png)

 Both, master and slave containers can scale. For true autoscaling, just remove the label constraints for the `monitoring-slave = true` from the above config.
