Monitoring Appliances using Prometheus/Grafana

In this tutorial we will assume that you have deployed several instances of Web Safety secure web gateway/filtering proxy appliances and would like to configure a central hub for monitoring internal state of those appliances as well as setup an alerting system if case something goes wrong.

To achieve these goals, we will deploy a separate machine, install and configure Prometheus server on it for collection of system metrics, Loki for log aggregation and Grafana for presenting results to the admins.
