From 80f02ea55c24c46b2ca8589e30a231f4f9f2636f Mon Sep 17 00:00:00 2001
From: David Harrigan <dharrigan@gmail.com>

Subject: [PATCH] Use (Prometheus) node_exporter to expose metrics.

This new plugin allows for Prometheus to scrape an OPNsense installation for
metrics - including CPU, Memory, devices, interfaces and so on.

The data can then be used for remote monitoring/alerting of an OPNsense
installation, or indeed graphing using popular graphing technologies such as
Grafana.

closes #452
