Notes
=====

* The grafana default account is admin/admin. Don't forget to change this !!!
* In grafana you have to create a datasource for influxdb. Use `http://influxdb:8086` as URL and the informations you enter in INFLUXDB_USER, INFLUXDB_USER_PASSWORD and INFLUXDB_DB for username/password and database name.
* You can use this dashboard : https://grafana.com/dashboards/3056
