-[Prometheus](https://prometheus.io) metrics exporter for NETGEAR switches of the Smart Managed Plus series.
+Open metrics exporter for NETGEAR switches of the Smart Managed Plus series to provide data to databases such as [Prometheus](https://prometheus.io) or [InfluxDB](https://www.influxdata.com/).
+
+## What is the purpose?
+NETGEAR switches of the [Smart Managed Plus series](https://www.netgear.de/business/products/switches/web-managed/) do not provide a standards conform interface for providing statistics of traffic and other information. There is no support for monitoring protocols such as [SNMP](https://en.wikipedia.org/wiki/Simple_Network_Management_Protocol). Still these switches are deployed in large numbers in professional and private environments where monitoring of the switches is highly desired. A common solution for monitoring is to store the data in a [Prometheus](https://prometheus.io) database and visualize and alert with tools such as [Grafana](https://grafana.com/). prosafe_exporter_python provides a tool that colelcts the data from the switches webinterface and provides it using the [OpenMetrics format](https://openmetrics.io/) that can be directly used in [Prometheus](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#scrape_config) or [Influx scrape jobs](https://docs.influxdata.com/influxdb/v2.0/write-data/no-code/scrape-data/manage-scrapers/create-a-scraper/).
