## Requirements

Dependencies:

* see requirements.txt

## Configuration

Create `config.yaml`:

```yaml
---
interval: 5
port: 8000
username: user1
password: secret
hosts:
  - srv1-112.mgmt.wtb1.ch.abainfra.net
  - srv2-112.mgmt.wtb1.ch.abainfra.net
  - srv3-112.mgmt.wtb1.ch.abainfra.net
  - srv4-112.mgmt.wtb1.ch.abainfra.net
```

or:

```yaml
---
interval: 5
port: 8000
username: user1
password: secret1
hosts:
  - fqdn: srv1-112.mgmt.wtb1.ch.abainfra.net
    username: user2
    password: secret2
  - fqdn: srv2-112.mgmt.wtb1.ch.abainfra.net
    username: user3
    password: secret3
  - fqdn: srv3-112.mgmt.wtb1.ch.abainfra.net
    username: user4
    password: secret4
  - fqdn: srv4-112.mgmt.wtb1.ch.abainfra.net
    username: user5
    password: secret5
```

The `port`, `interval` are optional and can be overwritten by argument. Save default values are hardcoded.
