 This application aims to help monitor Pure Storage FlashArrays by providing an "exporter", which means it extracts data from the Purity API and converts it to the OpenMetrics format, which is for instance consumable by Prometheus.
 
-The stateless design of the exporter allows for easy configuration management as well as scalability for a whole fleet of Pure Storage systems. Each time Prometheus scrapes metrics for a specific system, it should provide the hostname via GET parameter and the API token as Authorization token to this exporter.

 To monitor your Pure Storage appliances, you will need to create a new dedicated user on your array, and assign read-only permissions to it. Afterwards, you also have to create a new API key.
