Example Playbook
----------------

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:

```yaml
- name: Installing Prometheus on hosted machine
  hosts: vagrant1
  sudo: yes
  roles:
    - role: ansible-prometheus
      prometheus_config_scrape_configs:
        - job_name: 'prometheus'
          honor_labels: true
          scrape_interval: '15s'
          scrape_timeout: '3s'
          metrics_path: '/metrics'
          scheme: 'http'
          static_configs:
            - targets:
                - 'localhost:9090' # Prometheus itself
                - 'localhost:9100' # Node exporter
        - job_name: 'consul-services'
          consul_sd_configs:
            - server: "localhost:8500"
```
