Installation Install using the RPM file of the Fuel Plugins Catalog
============ ------------------------------------------------------
Prior to installing the StackLight Collector Plugin,
you may want to install the backend services the *collector* uses
to store the data. These backend services include:
* Elasticsearch
* InfluxDB
* Nagios
There are two installation options:
1. Install the backend services automatically within a Fuel environment using the Fuel Plugins listed below.

* `StackLight Infrastructure Alerting Fuel Plugin Installation Guide <http://fuel-plugin-lma-infrastructure-alerting.readthedocs.io/en/latest/installation.html#installation-guide>`_.
2. Install the backend services on your own outside of a Fuel environment.
Note that in this case, the installation must comply with the StackLight Collector
